Keratoconus Patient with Transplant and ALK now 20/25 with GVR Scleral Lens

The young woman in the center of this photo was diagnosed with keratoconus many years ago. In the 1980's she underwent corneal transplant surgery in her right eye. Over the years this patient has had difficulties wearing any type of contact lens to restore quality vision especially in her right eye which is the eye with the transplanted cornea. In 2000, this patient was referred to a internationally renown eye institution where 2 surgical incisions (AK surgery) were placed into the transplanted cornea in an effort to decrease the corneal astigmatism. The surgical incisions in the right transplanted cornea never healed and remained open to this day. The vision in this patient's right eye decreased after this surgery and she continued to experience unstable vision along with frequent eye pain. Last year in an effort to stabilize her corneas she underwent Collagen Cross Linking therapy. When this patient first visited out office 3 months ago, the visual acuity in her right eye was 20/800 and in her left eye 20/250. Over the last 3 months we have been fitting her with GVR Scleral lenses. With these lenses this patient is corrected to 20/25 vision in each eye. She can now see clearly and comfortably with all day lens wear. In the bottom left photo you can see a profile of her right cornea. The faint grey line is where the host cornea and donor cornea meet. Look carefully toward the bottom of this photo. You will note a curved line within the lower portion of the corneal transplant. This is one of the open incisions placed into this cornea. The bottom right photo is a frontal view of the transplanted cornea. Note the curved line at the top of the photo going from 11:00 O'Clock to 2:00 O'Clock and the curved line at the bottom of the photo going from 6:00 O'Clock to 8:00 O'Clock. These curved lines are the AK or "relaxing" incisions which created many problems for this patient. These incisions are open exposing the internal corneal tissues to the environment and the blinking action of the eyelids. The scleral lenses, in addition to providing vision also are acting to protect the compromised cornea and to keep the cornea in a moist environment. I feel that this patient will be able to wear her scleral lenses comfortably and with clear vision for many years.

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
