The great majority of patients are able to wear their scleral lenses almost all of their waking hours without problems.ĭr. These lenses are almost always very comfortable and the vision provided by them is extremely good. Scleral lenses are designed to fit with little or no lens movement during blinks, making them more stable on the eye, compared with traditional corneal gas permeable lenses. This liquid acts as a buffer and protects the compromised corneal tissue. In doing so, scleral lenses functionally replace the irregular cornea with a perfectly smooth optical surface to correct vision problems caused by, keratoconus, Lasik failures, post-surgical complications, and other corneal irregularities.īecause scleral lenses are designed to vault the corneal surface and rest on the less sensitive surface of the sclera, these lenses often are more comfortable for a person with corneal irregularities caused by keratoconus and other corneal irregularities A special liquid fills the space between the back surface of the lens and the front surface of the cornea. Scleral contacts are large-diameter gas permeable contact lenses specially designed to vault the entire corneal surface and rest on the “white” of the eye ( sclera). The problem we face as eye care practitioners is fitting the steep areas if the cornea without adversely affecting the flatter areas. Because so much of the cornea can be affected, fitting this type of cornea can be challenging. It is not unusual for 50% or more of the corneal surface to be involved. Pellucid corneas involve a larger distorted geographic area usually extending from the inferior corneal margins up to the center of the cornea. This entry was posted in Ectasia, Keratoconus, Pellucid Marginal Degeneration (PMD), PROSE Lens, Scleral lenses on Maby Post LASIK Doctor.Pellucid Marginal Degeneration is a sub-category of Keratoconus. Irwin Azman specializes in keratoconus, LASIK failures and other corneal irregularities neither avoids nor declines the challenge of prescribing the most difficult cases. Irwin Azman, Keratoconus Specialists in Maryland, prescribes PVR PROSE Lenses for a variety of hard-to-fit eyes, including patients with Stevens-Johnson Syndrome, Radial Keratotomy and Lasik Complications and Lasik failures, keratoconus, Corneal Ectasia, Post-Surgical Vision Loss, and Pellucid Marginal Degeneration.ĭr. In doing so, PROSE scleral lenses functionally replace the irregular cornea with a perfectly smooth optical surface to correct vision problems caused by, keratoconus, Lasik failures, post-surgical complications, and other corneal irregularities.īecause PROSE Lenses / scleral lenses are designed to vault the corneal surface and rest on the less sensitive surface of the sclera, these lenses often are more comfortable for a person with corneal irregularities caused by keratoconus and other corneal irregularities A special liquid fills the space between the back surface of the lens and the front surface of the cornea. PROSE Lenses are large-diameter gas permeable contact lenses specially designed to vault the entire corneal surface and rest on the “white” of the eye (sclera). With an exact fit, there is proper movement, comfort, and perfect vision. Utilizing our knowledge, experience, and technology, like the Vistante- Optical Coherence Tomography OCT, we are able to customize a prosthetic PROSE lens, with the precise measurements down to the micron. Our PVR PROSE Treatment is a process that uses a prosthetic device, like a scleral lens, to replace the ocular surface to provide functional vision to complex corneal conditions.
