FAQ for Radial Keratotomy and Scleral Lenses

Dr. Boshnick; I had Radial Keratotomy surgery in the 1908’s follow by LASIK surgery about 10 years ago. I am having terrible problems with blurred, distorted vision especially at night. My ophthalmologist suggested that I have “Replacement Lens Surgery” to restore my vision. Do you think that this will help me?

Absolutely not. The reason you are not seeing clearly is because your corneas are distorted. We see this all the time in patients with surgical histories similar to yours. Placing an intra-ocular lens into the eye behind the cornea will not improve your vision. On the contrary, there are real risks of cataract formation and other ocular conditions such as infections, glaucoma and retinal tears and detachments. Think of it like this: If you are driving your car with a windshield that is distorted or warped, changing your eyeglasses or your eyeglasses prescription will not allow you to see clearly. If, however, you placed a new windshield over the distorted windshield with a liquid reservoir in between, you would have clear vision with the 2 windshields in place. This may not seem logical to you but optically speaking what I am writing here is true. In the same way, placing a gas permeable scleral lens over your distorted corneas will provide you with clear, comfortable vision once again. This is because the scleral lens vaults over the compromised cornea and replaces it as an optical surface. A liquid interface (.9% sterile saline solution) exists between the back surface of the lens and the front surface of the cornea. Just know that there are no surgeries (PRK, CK, LASIK, LASEK, SMILE, etc.) that will restore the vision you have lost due to your previous refractive eye surgeries. The only technology that will allow you to see clearly and comfortably once again is a well fit scleral lens such as the GVR Scleral lens.

The Wavefront Scleral Lens

The corneal irregularities created by refractive surgeries, such as LASIK and RK, are responsible for ghosting, halos, starbursting, and loss of contrast sensitivity. These "higher order aberrations" may exist on both the anterior and posterior. With aberrometry, the defects of the entire optical system can now be corrected by a scleral lens.

Autologous Serum for Dry Eyes

Dry eye conditions are among the most challenging conditions faced by refractive surgery patients. With autologous serum, blood is spun down to plasma, forming an eye drop that helps rehabilitate the cornea.

Optimum Infinite Gas Permeable Material

I am happy to announce that our Global Vision Rehabilitation Center will be designing and fitting all of our “high need” patients with the Optimum Infinite gas permeable contact lens material. The Optimum Infinite material is the most oxygen permeable material ever to be approved by the FDA. In addition, this newly FDA approved material includes a UV lens blocker. Now for the first time, with certain patients, wearing a scleral lens made with the Infinite material under extended wear conditions can be considered.

SMAP 3D Scleral Lens Design

NEW: Powerpoint presentation on SMAP 3D

Last year we introduced an exciting piece of technology that has allowed us to custom design a scleral lens much more accurately. It is the SMAP 3D, which is a computer attached to a dedicated camera that allows us to obtain a 3 dimensional image of the entire front surface of the eye, including the cornea and the surrounding white portion of the eye (the sclera). Up until now there has not been any technology that would allow us to measure the ocular curvatures outside the cornea. The SMAP allows us to do this. Read More

Blurred Vision, Burning Eyes: This Is a Lasik Success?

EyePrint Pro

EyePrintPro technology creates a scleral lens based on a mold of the cornea. The molding is accurate to 1 or 2 microns and fits perfectly because it exactly mirrors the irregularities of the individual corneal surface. The technology is well suited for post-Lasik, Keratoconus, RK, eye injury, and corneal transplant patients. Read More in this PDF about EyePrintPro Scleral Lens Technology
