Dr. Delgado is a Scleral Contact Lens Specialist
Scleral contacts are large-diameter gas permeable contact lenses specially designed to vault over the entire corneal surface and rest on the “white” of the eye (sclera). 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.
Because 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. A special liquid fills the space between the back surface of the lens and the front surface of the cornea. This liquid acts as a buffer and protects the compromised corneal tissue. 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. These lenses are almost always very comfortable and the vision provided by them is extremely good. The great majority of patients are able to wear their scleral lenses almost all of their waking hours without problems.
Dr. Delgado prescribes scleral contact lenses for a variety of hard-to-fit eyes, including patients with Stevens-Johnson Syndrome, Radial Keratotomy and Lasik Complications and failures, Keratoconus, Corneal Ectasia, Post-Surgical Vision Loss, and Pellucid Marginal Degeneration.
