Zembla Documentary on Lasik, Pain, and Suicidality

This Lasik documentary was created by investigative journalists in Holland. The language is mostly Dutch, with English subtitles. The documentary focuses on corneal neuropathic path after Lasik and the suicidality it creates. Dutch physician Dr. Michael Brouwer and other Lasik sufferers in Holland are interviewed, as is Dr. Edward Boshnick in the United States (see EyeFreedom.com). The investigators ask: Is the experience of pain after Lasik really uncommon? What are the consequences when it occurs? Also interviewed are Dr. David Barsook and Dr. Morris Waxler. Dr. Barsook is Director of the Pain and Imaging Neuroscience (P.A.I.N.) Group at Boston Children’s Hospital, MGH ,and McLean Hospital at Harvard University. Dr. Barsook maintains that corneal pain after Lasik follows an established model of neuropathic pain. Dr. Morris Waxler is the FDA's former chief research scientist on Lasik. Dr. Waxler maintains at his website HelpStopLasik.com that "The FDA does not want to admit that millions of people have now had a surgery that never should have been approved by its own rules. The FDA is now engaged in covering-up a scandal and an epidemic, and its own corrupt practices. This should be exposed, and LASIK should end." He revisits these conclusions in the video.

RK

GVR Scleral Lens and RK

Radial Keratotomy (RK) was the first refractive surgical procedure introduced into the United States. Millions of patients around the world underwent this needless and harmful procedure in the 1980's and 1990's. Over two million procedures were done in the United States and Canada alone. In addition, over a million LASIK procedures were later done to these same patients in an attempt to undo the damage done by the initial RK surgeries. The end result of these multiple refractive surgical procedures was millions of permanently damaged eyes requiring either corneal transplant surgery or the use of specialty contact or scleral lenses.

Radial Keratotomy involved the making of small deep slices into the cornea (the front surface of the eye) in an attempt to reduce nearsightedness (myopia) and astigmatism. The long term results of RK were complications that were so horrific that many of these patients were unable to function visually either with eyeglasses or contact lenses. In addition to the reduced vision, most of these hurt patients experienced significant ocular discomfort and pain. Many complications occurred years after the surgeries were done. These complications include:

  • 1. Loss of best corrected visual acuity.
  • 2. Double or triple vision.
  • 3. Irregular corneal curvatures.
  • 4. Unstable or fluctuating vision.
  • 5. Severe dry eye.
  • 6. Halos, glare and reduced indoor and night vision.
  • 7. Permanently open incisions.
  • 8. Recurrent ocular infections and inflammation.
  • 9 Severe depression and in some cases thoughts of suicide.

Over the years our specialty practice has treated thousands of RK patients who also underwent additional RK procedures followed by one or more LASIK procedures. In every instance, the additional surgical procedures only made matters worse. Many of these patients (less than 5%) eventually needed to undergo corneal transplant surgery.

In recent years advancements in scleral lens technology have allowed the great majority of this hurt patient population to see clearly and comfortably once again. Virtually every hurt post-RK/ post-LASIK patient who were fit with the GVR Scleral lens experienced a dramatic improvement in their visual acuity and ocular comfort.

The GVR Scleral lens is unique in that this lens vaults over the compromised cornea and rests on the white portion of the eye known as the sclera. Sterile unpreserved saline solution fills the space between the back surface of the lens and the front surface of the cornea. Comfort and vision are almost always excellent. In addition, the dryness (scratchy and itchy) issues that so many post-refractive surgical patients experience are for the most part gone. In other words, the GVR Scleral lens has a therapeutic effect of the damaged eye. It is not unusual for a post-RK patient to comment to us after having received their GVR Scleral lenses that they now have their life back.

An Example: This eye underwent R-K surgery in 1988. LASIK was performed in 2002. Shortly thereafter, post-LASIK ectasia developed. The R-K incisions are still open. A dye was instilled onto the corneal surface. You can tell that the incisions are still open because the dye can be seen within the incisions. The green-yellow circular line going around the periphery of the cornea is the LASIK flap. We fit this eye with a GVR Scleral lens in 2007 which has provided this eye with clear stable vision ever since.

RK Thirty Years Ago with Extreme Discomfort. Seeing Clearly with GVR Scleral Lens

This is a photo of an eye that underwent Radial Keratotomy (RK) about 30 years ago. Fluorescein dye was instilled on the ocular surface to make the RK incisions more visible. Note the yellow-green dye within the deep RK incisions. This tells you that these incisions never closed. In addition, virtually every post-RK cornea is irregular and dry. Last year this eye underwent cataract surgery. During the surgery, the vertical incision extending downward from 12:00 ruptured forcing the cataract surgeon to suture the open wound. Note the increased staining in the superior portion of this cornea. Without correction, this patient not only has poor vision with this eye but also extreme discomfort (burning, dryness etc.). This patient is now wearing a scleral lens on this eye which is not only protecting this compromised eye from the environment and the blinking action of the eyelids but also providing this patient with clear, stable vision once again. Scleral lenses are now the "standard of care" when it comes to treating post-refractive surgical corneas. That is corneas that have been altered by LASIK, Radial Keratotomy and a host of other harmful, unnecessary surgeries.

Radial Keratotomy Corrected to 20/100 with Glasses, now 20/20 with GVR Scleral Lens

This is a photo of me with my patient Ricardo, who has been visiting our practice from Guatemala for the past 10 years on a yearly basis for his annual eye examinations. About 30 years ago, Ricardo underwent Radial Keratotomy surgery in both eyes. While his vision at first was quite good for the first few years, his vision gradually started to deteriorate. When I first met Ricardo, he was wearing eyeglasses which were providing him with 20/100 vision with a lot of visual distortions. He tried to wear various contact lens designs which were either uncomfortable or were unable to provide him with functional vision. 10 years ago, we fit Ricardo with GVR Scleral lenses. With these lenses Ricardo has clear (20/20) vision both at distance and close up and is able wear his lenses all day comfortably. Over the past 10 years we have only had to make a few changes to his scleral lenses. The 2nd photo seen below shows a close up view of Ricardo's open RK incisions. Note the blood vessel growth along the incisions. The last image was taken with a technology known as "Optical Coherence Tomography" or OCT. In this image the top 2 curves lines represent the front and back surfaces of the scleral lens. The large grey structure going left to right is the cornea. Note the wide, open break in the cornea on the right side of the image. This is an open RK incision that will never heal. Ricardo's scleral lens protects this eye from the blinking action of the eyelids and from the environment. In addition, because of the liquid reservoir between the back surface of the lens and the front surface of the cornea, Ricardo's eye is always in a moist environment. I expect Ricardo to be able to wear his scleral lenses for many years with excellent comfort and vision.

Radial Keratotomy on Transplanted Cornea now 20/30 with GVR Scleral Lens

What was the surgeon thinking when he did this surgery? What you see in this photo is an eye with a transplanted cornea that later underwent Radial Keratotomy surgery. For many years after, this eye was legally blind since no spectacle lens or contact lens was able to provide this patient with functional vision. Eventually this eye was fit with a scleral lens which is allowing this patient to see 20/30 with comfortable vision with this eye.

Radial Keratotomy Incisions Bursted During Cataract Surgery. Patient 20/25 with GVR Scleral Lens

This eye underwent Radial Keratotomy (RK) surgery in the 1980's. Last year cataract surgery was done on this eye. During the cataract surgery, the open RK incision extending downward vertically from 12:00 O'Clock burst open requiring suturing in this part of the cornea. This photo shows the open RK incisions extending from the edge of the cornea toward the center. Note the scarring and blood vessel growth at the top of the photo. When this patient was seen in our office, this eye was very red and painful. In addition, the cornea is very distorted and irregular. This eye was fit with a scleral lens which is providing the patient with 20/25 vision without any distortions. To patients unfamiliar with refractive surgery complications, just know that the people who brought you Radial Keratotomy surgery are the same people who are bringing you LASIK, PRK, SMILE, CK, ALK and so on. Unnecessary elective surgeries done today may create untold havoc many years down the road. This eye is protected by the scleral lens and is no longer painful

Radial Keratotomy, then Lasik, then Transplant, now 20/25 with GVR Scleral Lens

These are photos of the same eye. In 1993, this eye underwent Radial Keratotomy surgery for the elimination of myopia and astigmatism. When the vision in this eye began deteriorating several years later LASIK surgery was done. The LASIK surgery following the RK surgery turned out to be disastrous, visually for this patient. In 2010, corneal transplant surgery was done in an effort to restore vision. For 6 years, this eye was unable to tolerate any form of soft or rigid contact lens. This eye was recently fit with a gas permeable scleral lens which is now allowing this patient to see 20/25 with this eye. The photo below is a frontal view of the new scleral lens over the transplanted cornea. The 2nd photo is a profile view of the same transplanted cornea. The center of gravity of this cornea is so far out that it is not possible for any contact lens to remain stable on this eye. For this reason a well fit scleral lens can provide lens stability and ocular comfort while at the same time restoring excellent vision once again.

RK Patient Happy for 20 Years, Then 20/50 and 20/200 and Uncorrectable. Now 20/20 with GVR Scleral Lens

The woman standing next to me underwent Radial Keratotomy (RK) surgery over 25 years ago. This surgery involves making radial incisions onto the corneal surface from the center of the cornea unto the periphery much like the spokes on a bicycle wheel. For 20 years, this patient was satisfied with her vision. Over the last 5 or 6 years her vision began to fluctuate and to deteriorate. When this patient first came in, her corrected vision was 20/50 in one eye and less than 20/200 in the other eye. We fit both of this patient's eyes with GVR Scleral lenses which are allowing her to see 20/20 in each eye with all day comfort. In the photo below, you can see the open RK incisions. These incisions will always remain open. The scleral lenses that were provided to this patient will not only correct her vision but also protect her corneas and keep them in a wet environment.

Happy with RK for 11 Years, then Struggling due to Declining Vision, Now 20/20 with GVR Scleral Lens

The patient in this photo underwent Radial Keratotomy (RK) surgery in both eyes in 1990. For 11 years he was very happy with his post RK vision. In 2001 his vision began to fail, requiring him to wear eyeglasses which needed to be changed quite frequently. As the years went by he needed stronger and stronger eyeglasses. Over a 14 year period he struggled with a variety of both soft and hard contact lenses which were not only very uncomfortable but provided him with unstable vision. When this patient first visited our office several months ago, he required over +10.00 diopters of spectacle correction to get him to see the 20/30 line with significant distortions. 6 weeks ago we fit this patient with GVR Scleral lenses. With his new scleral lenses this patient can see clearly (20/20) and comfortably with all day lens wear and without any distortions. In the photo below note the numerous RK incisions which remain open and unhealed to this day. I feel that this patient will be able to wear his scleral lenses comfortably with clear, stable undistorted vision for many years to come.

Radial Keratotomy in 1998, Lasik in 2002, Followed by Ectasia, has Six Years Good Vision with GVR Scleral Lens

This patient underwent Radial Keratotomy (R-K) surgery in both eyes in 1988. Several years later her vision began to deteriorate and in the following years was not able to obtain satisfactory vision with either eyeglasses or contact lenses. In 2002, she visited another corneal surgeon who encouraged her to undergo LASIK surgery to correct her distorted corneas created by the R-K surgery. Shortly afterwards, a condition known as post-LASIK corneal ectasia took place. This condition is a risk factor in patients who have undergone LASIK surgery, however, the risk of this developing is much greater in patients who have undergone prior refractive surgeries such as R-K. Corneal Ectasia involves a protrusion of the front surface of the eye (the cornea). This patient's cornea was not only extremely distorted, she also suffered from chronic dry eyes and ocular pain. Due to the significant pain she had been experiencing and her inability to obtain functional vision with eyeglasses, this patient visited our office 6 years ago seeking help. 6 years ago we fit this patient with GVR Scleral lenses which have provided her with clear, stable vision. Today, this patient came in for her yearly comprehensive eye and lens evaluation. Both of her corneas have remained stable and she is seeing clearly and comfortably with all day lens wear. Below the photo of this patient with me can be seen photos of her right and left eye with her Scleral lenses over her scarred corneas. If you look carefully you can see the R-K incisions. Next to these photos is a photo of her right cornea without a lens in place. A dye was instilled onto the front surface of her eye to demonstrate the open R-K incisions along with the LASIK flap. The straight lines in the cornea are the R-K incisions which still remain open after all these years. One can tell they are open because the dye can be seen within the corneal incisions. The round circular line going around the periphery of the cornea is the LASIK flap incision. This patient will need to be seen at least once each year to make certain that infection does not occur and that her corneas remain clear and stable.

RK Patient from Chile Seeing Well For Five Years with Scleral Lens

The photo below is of my patient David on the right with his wife, Patty in the center. David and Patty traveled to see us from Santiago, Chile. David underwent Radial Keratotomy surgery (R-K) in 1989 followed by LASIK surgery a number of years later. What resulted from these surgeries were severely distorted corneas along with a very dry eye. Without corrective lenses, David has no functional vision (less than 20/800). Eyeglasses and conventional contact lenses will not allow him to see correctly. 5 years ago, we fit David with GVR Scleral lenses. For the first time in many years, David has been able to see clearly and comfortably once again. Every year for the past 5 years, David has returned to Miami to visit our office for yearly examinations. Over the years, David's vision has remained clear and his corneas have remained stable. In addition,because David's scleral lenses keep his corneas in a liquid environment, he no longer has any dry eye symptoms. Before visiting us, 5 years ago, David was told that his only hope for clear vision was to undergo corneal transplant surgery. Based on how well David has done with his scleral lenses over the last 5 years, I don't feel that he will ever need to undergo corneal transplant surgery. The lower photo is David's right cornea with a GVR Scleral lens over it. The semi-round white cloudy spot below his pupil is due to a break or tear in the back surface of his cornea. This tear took place because his cornea became very pronounced over the years following his surgeries. When this happened fluid from inside the eye entered the cornea and created this milky-white spot. This condition is called "hydrops".

Fluctuating Radial Keratomy Vision Corrected to 20/20 with GVR Scleral Lens

The patient in this photo underwent Radial Keratotomy (R-K) eye surgery in 1990 for the purpose of eliminating his myopia and astigmatism and his dependence on eyeglasses. For many years his post-surgical vision was very good. In recent years his vision began to deteriorate. He noticed that his vision was not stable and would fluctuate depending on the day, the time of the day and the surrounding lighting conditions. Last year he underwent Collagen Cross-Linking treatment in both eyes in an effort to stabilize his corneas and to improve his uncorrected visual acuity. Six weeks ago we fit this patient with GVR Scleral lenses. For the first time in many years he is seeing clearly (20/20) and comfortably with all day lens wear. In addition, his vision is stable regardless of the surrounding lighting conditions. In the lower photo can be seen the deeply scarred R-K incisions in his cornea. These incisions are still open 25 years after the R-K surgery was done. Over this scarred cornea is a GVR Scleral lens. In addition to allowing this eye to see clearly once again, this scleral lens protects the compromised cornea from the environment and the blinking action of the eyelids.

Radial Keratotomy Patient Seeing 20/20 Comfortably with GVR Scleral Lens

This patient underwent Radial Keratotomy eye surgery in 1992 in an effort to eliminate her need for eyeglasses. She saw relatively well until 2012 when she noticed that her vision deteriorated very rapidly. She visited a number of eye clinics seeking help in restoring her vision. The eyeglasses and contact lenses that were prescribed for her were unable to provide her with functional vision. In October, 2012 she visited a corneal surgeon for a LASIK surgical consultation. This corneal surgeon declined to do LASIK telling her that she faced a greater risk for further vision loss with any additional refractive surgical procedures. In November, 2012, this patient visited our office. We examined her and fit both eyes with GVR Scleral lenses. With these special lenses, this patient can see clearly (20/20) and comfortably once again with all day lens wear. For the past several years both corneas have remained stable. The 2 photos below show her corneas with open incisions. The green color is due to a special dye that we instilled in her eyes. This view is taken through a microscope with a filter placed before each eye. Radial Keratotomy (R-K) incisions typically remain open and do not heal.The bright green linear lines are the open R-K incisions that have not healed 20+ years following her R-K surgery. Because of this, there is a life long risk of corneal and other intra-ocular infections. The scleral lenses that we designed for her not only provide this patient with excellent vision but also protect her corneas from infections and possible ocular trauma. In addition, because there is a liquid reservoir between the back surface of the lenses and the front surface of her corneas (the lenses do not touch the corneas) her corneas will always be in a liquid environment and not be dry.

Three RKs, Wide and Deep Incisions, Patient Seeing Clearly and Comfortably All Day with GVR Scleral Lens

This patient underwent 3 separate Radial Keratotomy surgeries over a 12 month period. These eye surgeries took place over 25 years ago. This patient's vision deteriorated with each successive surgical procedure. When first seen in our office, her corneas were extremely distorted and "beaten up." Both corneas had numerous wide, deep and open incisions. In addition to blurred distorted vision, this patient was so photophobic that she had to wear 2 pair of sunglasses (one over the other) to subdue to light so that she could function even indoors. The image below and to the left is an image of one of her corneas with a GVR Scleral lens over it. Note the open incisions to the right and left side of the image. The colored images below and to the right are her corneal topographies. The varying shades and colors represent the many elevations and depressions of her corneal surfaces. 3 years ago we fit this patient with GVR Scleral lenses. With these lenses she is able to see clearly and comfortably with all day wear. In addition, she is no longer photophobic (light sensitive) and does not need to wear sunglasses indoors since receiving her lenses.

Deteriorating RK Vision Advised for Transplant now 20/20 with GVR Scleral Lens

This patient visited our office from Guatemala. In 1990 he underwent 2 separate radial keratotomy (RK) surgeries in an attempt to eliminate his myopia. While his vision was improved for a period of years, eventually his vision began to deteriorate. When his vision could not be corrected any longer with eyeglasses or contact lenses, he visited a number of corneal specialists both in his country and in the United States for help. After being told that his only option would be corneal transplant surgery, he visited our office in 2008 for another opinion. If you look carefully at the attached images, you will see that his RK incisions are still open after all these years. The cross sectional corneal image shows a GVR Scleral lens over his cornea with an open incision that nearly perforated the cornea. Since 2008 he has been wearing his GVR Scleral lenses comfortably with all day wear and with 20/20 vision without any visual distortions. This patient will never need corneal transplant surgery.

Radial Keratotomy Patient Advised to Seek Transplant now 20/20 in Each Eye with GVR Scleral Lens

This patient visited out office last year from Argentina. 25 years ago he underwent 2 separate Radial Keratotomy surgeries in each eye followed by LASIK surgery in each eye in 2002. Over the years his best corrected visual acuity deteriorated to less than 20/50 in each eye with eyeglasses and contact lenses. After being told that he needed bilateral corneal transplants, he decided to visit us for a 2nd opinion. If you look carefully at the photos placed here you will notice that the RK incisions never healed but remained open. In addition all of these elective surgeries left both corneas extremely distorted and very dry. 15 months ago we fit this patient with GVR Scleral lenses. These lenses act as new corneas and are providing this patient with stable, clear (20/20) vision in each eye with excellent all day comfort. In addition, because these lenses vault over the corneas and keep the corneas in a liquid environment, dry eyes are no longer an issue.

Unstable Radial Keratotomy Cornea has Distortions Fixed by GVR Scleral Lens

In the 1988, this eye underwent an eye surgery known as Radial Keratotomy. Deep slices or incisions were made into the cornea in an effort to reduce this patient's dependance on eyeglasses and contact lenses. What took place instead was a large visual error (prescription) that became increasingly unstable and not correctable with eyeglasses or contact lenses. In addition, this eye presented the patient with halos, glare, light sensitivity and double vision. Look carefully and you will note blood vessels growing onto the cornea, where blood vessels do not belong. Several years ago we fit this eye with a GVR Scleral lens which has eliminated all of the visual distortions created by this surgery. In addition, the patient is no longer light sensitive. Because this lens acts as both a protective and therapeutic device we are hopeful that the growth of blood vessels onto the cornea will stop and hopefully recede.

Deteriorating Vision After RK for Police Officer, now 20/20 with GVR Scleral Lens

This police officer underwent several Radial Keratotomy eye surgeries in 1988. As the years went by his vision began to deteriorate to the point where he could no longer do his work. He went to a number of eye clinics and eye institutions seeking help but was told that his only choice was to undergo corneal transplant surgery. Contact lenses proved painful and eyeglasses were not able to provide him with functional vision. In addition his vision was constantly changing during he day. At night he was experiencing halos, glare and multiple images with each eye. Last year we fit this office with GVR lenses. Since last year his vision has been stable. He can see clearly (20/20) during the day and at night without glare, halos or multiple images. In addition, he is able to wear his lenses all day comfortably without any eye irritation or redness.

Radial Keratotomy Equals Pain and Blurry Vision, but Clear and Comfortable with GVR Scleral Lens

This patient had 2 separate R-K (Radial Keratotomy) eye surgeries done in the 1980's. What followed were years of painfully red eyes along with blurred, distorted vision. Over the years she visited a number of eye clinics and institutions that provided her with many types of contact lenses and eyeglasses. None of these items provided her with functional vision. 6 years ago we examined this patient and fit her with GVR Scleral lenses. For the past 6 years she has had clear, undistorted functional vision. In addition she is able to wear her scleral lenses all day comfortably and her eyes are no longer red.

Radial Keratotomy followed by Lasik Equals More Vision Loss, now 20/20 with GVR Scleral Lens

The young woman in the middle of this photo lost quality vision and comfort due to Radial Keratotomy surgery done in the 1980's followed by LASIK surgery a number of years later. When her vision began to fail following Radial Keratotomy, she was told by a LASIK surgeon that LASIK would improve her vision. What took place was additional vision loss, and a very deep depression when no one in her community was able to help her regain her vision. 4 years ago, this patient visited us seeking help. At the initial visit we fit her with GVR Scleral lenses which have allowed her to see clearly (20/20) once again with excellent comfort and all day wear. The young lady to my patient's left is her little sister who accompanied my patient to Miami for her annual eye and vision examination.

Radial Keratotomy Produces Dry, Irregular Cornea, now 20/20 Each Eye with GVR Scleral Lens

This is a photo of our student extern David Yoo with a patient who visited our office from Guatemala. In the 1980's this patient underwent Radial Keratotomy (RK) eye surgery which created a very distorted, irregular and dry corneal surface. In addition, both corneas have large, deep open incisions which never healed. When this patient first came to visit us, her best corrected visual acuity was very poor. We provided this patient with GVR Scleral lenses which are now allowing her to see close to 20/20 in each eye. However, this patient's open incisions will require us to make ongoing lens changes over the next few months to improve the quality of her vision and her comfort. Almost all patients who underwent RK surgery have open incisions which expose the corneal sensory nerves to the environment. The GVR Scleral lenses will protect the compromised cornea and help to promote healing.

Radial Keratotomy Patient with Diminished Vision now 20/20 with GVR Scleral Lens

During the 1980s this patient underwent 3 separate Radial Keratotomy surgeries in an effort to eliminate his myopia and astigmatism. As the years went by his vision gradually started to deteriorate. His decreased vision was not correctable with either eyeglasses or contact lenses. Seeking an answer to his diminished vision, he visited several nationally renown eye institutions in 2001. Eventually one of these facilities performed 2 separate LASIK procedures over an 18 month period. The result of these 5 separate refractive surgeries was horribly distorted corneas with open R-K incisions, ocular pain and ever changing vision. 4 years ago we fit this patient with GVR Scleral lenses which have provided him with clear (20/20 vision), stable vision with all day comfort. Because these lenses also protect the injured corneas from the blinking action of the eyelids and the environment, he no longer has any ocular pain.

Radial Keratomy Patient with Pain, Distortions now 20/20 and Distortion-Free

In the 1980's, this patient underwent 4 separate radial keratotomy surgeries in her right eye and 3 separate radial keratotomy surgeries in her left eye. For many years she suffered from pain in both eyes, visual distortions in both eyes and daily changes in her vision. In the years following her surgeries she visited a number of eye institutions seeking help only to be told that she would need corneal transplant surgery in both eyes. In 2010 she was examined in our office and fit with GVR Scleral lenses. For the past 5 years, she has been able to wear her lenses comfortably all day, with clear 20/20 vision and without any vision distortions.

RK followed by Lasik Advised to Have Transplant, Avoids Transplant with GVR Scleral Lens

In the 1980's this patient underwent several separate Radial Keratotomy surgeries in an attempt to eliminate her myopia and to improve her vision. When this failed, she underwent 2 separate LASIK procedures 15 years later. She went to a world renown eye institution about 12 years ago seeking help to restore her lost vision. They were unable to help her and informed her that her only option was to undergo corneal transplant surgery in each eye. We have been working with this patient diligently for the past 8 years trying every known lens design and material in existence in an effort to give her clear, comfortable vision with all day wear. Last year we fit her with a new GVR lens design which is providing her with what our goal initially was. She now has clear, comfortable vision with all day lens wear. I feel that she will never need to undergo corneal transplant surgery in either eye.

RK Patient now 20/20 with GVR Scleral Lens

This patient underwent Radial Keratotomy surgery in both eyes in the 1980's followed by LASIK surgery in her left eye in 2003. For many years she suffered from blurred, unstable vision which could not be corrected with eyeglasses or contact lenses. In addition she suffered from significant ocular pain and light sensitivity. Two years ago she was fit with GVR Scleral lenses which have provided her with clear (20/20 vision),stable vision and all day comfort without any visual distortions.

ALK Complications addressed with GVR Scleral Lens

This patient (in center of photo) underwent a refractive surgical procedure known as Automated Lamellar Keratoplasty or ALK. The purpose of this surgery was to eliminate this patient's hyperopia (far sightedness) and astigmatism. For 8 years this patient was satisfied with his post-surgical vision. After 8 years during a 3 week period his vision deteriorated to the point where eyeglasses and contact lenses were unable to provide functional vision. For several years this patient visited a number of doctors who told him that his only option was to have corneal transplant surgery. 3 years ago we fit this patient with GVR Scleral lenses. With these lenses he is able to see clearly (20/20) and comfortably with all day lens wear. In the photo with the cornea immersed in dye you can see the outline of the ALK cornea flap. The lower photo to the right shows a cross section of the post-surgical cornea with the GVR Scleral lens over it. The scarring from the ALK surgery is visible in the center of the cornea. With the GVR Scleral lens, this patient will never need corneal transplant surgery. By the way, the young lady to the right is our student extern (soon to be eye doctor) Tina Cheung.

The structural effect of the RK incisions on this cornea is clearly visible in the OCT cross-section, where an incision appears on the right.

Scleral Lens over RK incisions

Like most patients we see with RK, the incisions remain open many years later, and in fact, never heal.
