A Few Words about the GVR (Global Vision Rehabilitative) Scleral Lens
For over 25 years our specialty contact lens practice has been devoted to the restoration of quality vision and ocular comfort to those patients who have been affected by keratoconus, refractive surgical complications, corneal transplant surgery, ocular trauma, chronic dry eyes, corneal dystrophies and degenerations and a host of other ocular conditions and diseases.
For this reason, we named our practice the Global Vision Rehabilitation Center. The great majority of our patients who have suffered vision loss are now wearing scleral lenses designed by us using propriety software and computers made by Zeiss Optical Corporation. Because of the unique nature of each scleral lens that we design we named and registered our scleral lens design as the GVR® Scleral lens.
Every eye is unique and different from every other eye in the world, much as a fingerprint is unique and different from every other fingerprint. A great deal of time is taken and numerous examinations and tests are done before a GVR® lens can be created. We are proud of the fact that we have many thousands of patients throughout the world wearing GVR® Scleral lenses, which are providing them with clear, comfortable vision once again. Many of these patients had no functional vision for years prior to visiting our specialty practice.
The photo below shows a large GVR Scleral lens filled with sterile unpreserved saline solution. This lens is significantly larger than a gas permeable contact lens. A scleral lens is not referred to as a “contact” lens because there is not contact between the lens and the cornea. The GVR scleral lens vaults over the cornea and rests on the white portion of the eye which is called the scleral. The saline solution that you see in this photo fills the space between the back surface of the scleral lens and the front surface
of the cornea. In other words, the cornea is always in a liquid environment. A gas permeable contact lens will not be able to address the many issues that confront a compromised cornea. So many of these corneas are dry and irritated. In addition, most of the altered corneas that we see at the Global Vision Rehabilitation Center are very distorted. A conventional gas permeable contact lens will have to rest on the compromised cornea. If the cornea is dry and irritated due to LASIK surgery, transplant surgery, trauma, disease or from keratoconus,this type of lens will only make matters worse because there is contact with the cornea. The same principle holds true for a hybrid lens as this lens also will have contact with the compromised cornea. Only the scleral lens has the ability to provide relief from pain and discomfort while at the same time provide excellent vision and promote healing to the compromised cornea.
