If You Have Dry Eyes Or Can’t Tolerate Contacts, You May Be A Candidate For Scleral Lenses
For people who are unable to tolerate contact lenses or have severe dry eye syndrome, there’s a different type of contact lens that can be life-changing when it comes to improved vision and comfort. Scleral lenses are larger than typical contact lenses, ranging from 14 mm to over 20 mm in diameter. They are called “scleral” lenses because they extend beyond the cornea onto the scleral, which is the white part of the eye.
Because the cornea is one of the most highly sensitive tissues in the body, traditional lenses that rest on the cornea can become quite uncomfortable for some lens wearers. But the conjunctive, which is the tissue that covers the sclera, is much less sensitive than the cornea. So, lenses that rest on the sclera rather than the cornea alone can be much more comfortable.
An added benefit is that because scleral lenses extend under the upper and lower lids, they remain centered and stable and rarely dislocate.
Candidates For Scleral Lenses
For patients who have damaged corneal tissue, scleral lenses are much more comfortable since they don’t touch the cornea. The cornea also benefits by being bathed all day with preservative-free saline, which rejuvenates the surface of the eye.
Likewise, people who have severe dry eye symptoms—whether from tear production imbalances, as a result of LASIK surgery, or due to other eye conditions—often benefit greatly from scleral lenses.
You may be a candidate for scleral lenses if you have:
- Severe dry eye syndrome
- Irregular or damaged corneas, such as from keratoconus, post-LASIK ectasia, or other causes
- Ocular allergies
- Nearsightedness, and are unable to wear other forms of lenses
- Farsightedness, and are unable to wear other forms of lenses
- Astigmatism, and are unable to wear other forms of lenses
- Presbyopia, and are unable to wear other forms of lenses
