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.

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
