At Total Eyecare, our Elko optometrist team is proud to be among your area leaders in the advanced diagnosis and corrective services of a wide number of eye conditions. We get a lot of questions about a particular treatment option known as scleral lenses. This relatively unknown yet effective type of contact lens may be the perfect vision correction option you've been looking for.
What Are Scleral Lenses?
Picture the size of a standard contact lens. Now, imagine a contact lens that's quite a bit larger than normal, so large in diameter, in fact, that it covers the entire cornea and actually comes to rest on the whites of your eyes (also known as the sclera).
This, in effect, is what scleral lenses are.
Scleral contact lenses are gas-permeable. They provide a smooth optical surface that will correct vision problems caused by refractive errors (which happen when light entering the eye does not focus properly on the retina).
Who Are Scleral Lenses For?
Scleral contact lenses are a great option for people who have been told they have hard-to-fit eyes on account of irregularities in the shape of their corneas. For instance, they may have an advanced form of astigmatism (a refractive error caused by an abnormal corneal shape) or a condition known as keratoconus, in which the cornea outwardly bulges. For these patients, standard contact lenses may not work very well and feel pretty uncomfortable. Scleral lenses, on the other hand, can offer an effective solution.
Because scleral contacts can also keep protective fluids in place between the lenses and the corneas, they are also a good vision-correcting option for people who suffer from a condition called keratoconjunctivitis sicca, or more commonly known as (chronic dry eye syndrome). Most dry eye sufferers are unable to tolerate regular contact lenses, however, the unique design of scleral contacts can allow for comfortable wear without exacerbating their symptoms.
But the list goes on: our Elko optometry team has also successfully prescribed scleral lenses for patients who have had corneal transplants as well as people with other dry-eye related conditions, including Stevens-Johnson syndrome, Sjorgen's syndrome, and graft-versus-host disease (GVHD). We even offer bifocal scleral lenses that can help people dealing with age-related blurry vision when looking at nearby objects (a common condition known as presbyopia).
Are Scleral Lenses Right For Me?
Have you wondered if scleral contact lenses may be a good fit for you? If so, we encourage you to call Total Eyecare today to schedule a contact lens exam. During an exam, one of our optometrists will thoroughly assess both the internal and external anatomy of your eyes, test your visual acuity, and determine the most appropriate vision-correcting services to meet your unique needs. If scleral lenses are determined to be a good fit, we'll be sure to go over with you in detail how to insert, remove, and care for your new lenses.
