Lasik in 2000, Ectasia in 2007, now 20/20 with GVR Scleral Lens

This is a photo of a patient and his wife who visited us from Santiago, Chile. In 2000 this patient underwent LASIK surgery. For 5 years following his surgery he saw clearly. In 2005 this patient started losing his vision in a progressive manner over the following years. In 2007 he was diagnosed with post-LASIK corneal ectasia. Corneal ectasia is a protrusion and thinning of the front surface of the eye (the cornea). This results in a very irregular, distorted cornea and distorted vision which cannot be corrected with eyeglasses or conventional contact lenses. This patient visited a number of doctors in his country seeking help with his vision. Several years ago he was fit with "piggy back" lenses. This is a combination of soft lenses placed on the eyes first followed by gas permeable lenses worn over the soft lenses. For several years this patient wore this lens combination which was not only painful but in addition the lenses would often pop out of his eyes. When we first saw this patient about 2 weeks ago, he could barely open his eyes. Both of his corneas had significant scarring from his small gas permeable lenses. Without his lenses this patient's visual acuity was less than 20/800 in each eye. With the lenses he first wore into our office his visual acuity was 20/80. We fit this patient with GVR Scleral lenses which now provide him with 20/20 vision in his right eye and 20/30 vision in his left eye. The reduced visual acuity in this patient's left eye was due to the corneal scarring in this eye. This patient returned home today. He is now able to wear his new lenses comfortably with all day lens wear. In the lower left photo you can see the corneal scarring created by his previous lenses. The lower right photo shows the protrusion (ectasia) that was caused by his LASIK surgery. I feel that this patient will be able to wear his new scleral lenses comfortably and with clear vision for many years to come.

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
