Scleral Lenses at Dr. Dorothy Park and Associates
One of the qualities that attract many wearers of corrective lenses to contacts is their small size. What could be more discreet and convenient than a pair of lenses that fit within the diameters of your corneas? Smaller isn't always better, though, especially for individuals with special vision needs. If you're one of those individuals, you may get better results with scleral lenses. Here at Dr. Dorothy Park and Associates, we can provide these specialized lenses to help you enjoy superior vision quality, unaffected by corneal irregularities or other complicating factors.
What Are Scleral Lenses?
In a sense, scleral lenses are actually a step into corrective vision's past, since the first contact lenses made available to the public belonged to this classification. Scleral contact lenses get their name from the fact that their rims rest, not on the corneal surface, but on the sclera, better known as the white of the eye. In fact, no part of these oversized lenses ever even touches the cornea, instead, their curvature extend slightly in front of the corneas.
The shape of scleral lenses offers some important advantages for people who have trouble with ordinary corneal contacts. For starters, people with extremely irregular corneas, such as severe astigmatism or the cone-shaped bulge caused by keratoconus, can't get much benefit from regular soft contacts at all. These contacts are designed to conform to the surface underneath them, meaning that they do nothing to compensate for significant irregularities. By contrast, scleral contacts, which are made of rigid gas-permeable materials, maintain just the right curvature at all times for proper vision correction, regardless of your corneal contours.
Scleral contact lenses hold other advantages as well. If you suffer from dry eye, for example, you may have had trouble finding soft contacts that don't aggravate the condition. Scleral contacts can help by trapping moisture in the space between the lens and the cornea.
Our optometrist will be happy to fit you for scleral lenses if corneal lenses are less than ideal for you. Depending on your specific needs, our optometrist may offer you a choice between full-sized scleral lenses or their smaller cousins, semi-scleral and corneo-scleral lenses. You may be pleasantly surprised to discover that your scleral lenses are actually even more comfortable to wear than traditional corneal lenses. That's because the sclera is less sensitive than the cornea.
