wavefront-aberrometer

The instrument seen here is an aberrometer and the technology that it provides us in known as “aberrometry”. This is a new technology that allows us to design a scleral lens with superior optics when compared to previous scleral lens designs. There are millions of patients around the world who have lost quality vision due to refractive surgery, keratoconus, corneal transplant surgery and corneal disease who suffer varying degrees of vision defects known as “higher order aberrations” or simply “HOA’S”. HOA’S are complex vision disorders responsible for patients experiencing ghosting, double vision, starbursts and halos around lights. Measuring these aberrations cannot be done by simply scanning the anterior surface of the eye. In order to identify and measure these aberrations, the aberrometer seen here is used to send a light into the eye. This light passes through the cornea and the lens of the eye and is reflected back to the retina. The reflected light is then identified and measured by the aberrometer. Finally, these aberrations (HOA’S) are displayed in 3D on the aberrometer’s computer screen. How the light passes through the eye is known as wavefront technology. The resulting aberration profiles are uploaded to a special laboratory that embeds this information into the surface of a highly oxygen permeable so that these HOA’S can be eliminated and the patient’s vision improved.

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
