Specialty Contact Lens Fittings (Duette and Scleral Lenses)
During your eye exam, your eye doctor determines if your vision requires corrective lenses, and what your prescription will be. After taking a precise measurement, your doctor might recommend scleral or Duette lenses for you. With different eye conditions, different contact lenses might be the best option.
When an irregularly-shaped cornea (sometimes caused by keratoconus) requires you to wear different contact lenses, ask about scleral lenses. Scleral lenses have a larger than normal diameter for contact lenses, and the cornea is one of the most sensitive parts of the body. The conjunctiva is a soft, clear tissue that lies over the cornea, and is much less sensitive. You’ll find much more comfort if you wear a contact lens that rests on the conjunctiva, rather than the cornea.
These gas permeable lenses date back to the early 1880’s, so there’s a long-standing proof that these larger-diameter lenses work. Despite their size, scleral lenses are actually quite comfortable. There’s less irritating movement because they stay tucked beneath the eyelids. They’re also stable, meaning they’re less likely to become dislodged, or become uncomfortable, requiring removal. If you’re prevented from wearing lenses from dry eye, these lenses act like a “fluid reservoir” between the lens and your eye.
Other Eye Issues
Scleral lenses can be the solution for other eye issues as well. If you’ve underwent a corneal transplant, or suffer from severe dry eye conditions caused by Sjogren’s syndrome, graft-versus-host disease (GVHD), or Stevens-Johnson syndrome, scleral lenses may be the solution.
Duette contact lenses
If you have astigmatism, duette lenses can make your vision sharper and clearer than ever before. These advanced-technology lenses now offer Tangible Hydra-PEG coating to offer all-day comfort. With multiple features, like a rigid center and breathability, these meet your vision requirements for the workplace and your lifestyle.
The rigid lenses prevent you from experiencing “toric lens-rotation” and your vision stays clear from the moment you put them in to when you take them out at night. Duette’s rigid center and outer skirt are both made with breathable materials, providing a steady stream of oxygen throughout the day. After taking an eye measurement, Dr. Bettner can make a custom gas permeable lens, just for you.
If you’re not satisfied with the vision provided by the contact lenses you already have, it might be time to discuss scleral or duette with Dr. Bettner and determine what’s best for you.
