Scleral Lenses from Your Hialeah Ophthalmologist
If you have ever been told you have hard-to-fit eyes, or you have had a bad experience wearing contact lenses, scleral lenses may provide you with the comfortable vision correct you seek. Scleral lenses differ from other contact lenses because they are much larger gas permeable contacts that cover the entire corneal surface as well as the sclera, or the white part of the eye. In contrast, your typical contact lenses cover just 75 to 80 percent of the cornea. Scleral lenses correct refractive errors, including nearsightedness, farsightedness, presbyopia, and astigmatism, and their specialized design means patients with an irregular cornea, cornea transplant, dry eye, keratoconus, irregular astigmatism and other conditions can benefit from the variety of scleral lenses at our Hialeah ophthalmologist, Vision Care & Surgery Associates.
Scleral Lenses For Dry Eyes
Traditional contact lenses can irritate patients with dry eyes. By covering more of the eye and landing on the white of the eye, scleral lenses help lock in hydration and prevent the dryness associated with other lenses. You can think of these lenses as a fluid reserve for your eyes. In fact, scleral lenses work for dry eyes caused not only by dry eye syndrome, but also Sjogren's syndrome, Stevens-Johnson syndrome, graft vs. host disease, neurotrophic keratopathy, and certain inflammatory conditions.
Scleral Lenses for Keratoconus
Keratoconus is a condition that impairs visions and makes wearing traditional contact lenses difficult because it changes the shape of the cornea from a dome to bulging cone. With scleral lenses for keratoconus, many patients have found a comfortable fit. Scleral lenses work because the larger size allows the lenses to vault over the cornea and land on the sclera instead. If you have keratoconus and have had trouble with other gas permeable lenses moving around on the eye, you may find that scleral lenses do a better job of staying in place.
Types of Scleral Lenses
Scleral lenses come in varying sizes to correct vision in people with differing needs. Our Hialeah ophthalmologist will use the latest diagnostic technology to determine the right fit for you. Standard scleral lenses are 19 mm in diameter to 24 mm in diameter. Patients with milder forms of hard-to-fit conditions, such as irregular astigmatism or keratoconus, may not need this large of lenses and instead wear mini-scleral lenses that are 14 mm in diameter to 18 mm in diameter. Whether you wear standard or mini size, scleral lenses will always cover the entire corneal surface of the eye.
