Scleral Lenses at Our McKinney TX Clinic
If you're still getting used to the idea of placing contact lenses in your eyes, the idea of using oversized lenses might seem even harder to assimilate. But scleral lenses can actually prove even more comfortable than standard corneal-sized lenses -- and they hold some crucial advantages for individuals with certain eye/vision problems. Here at First Eye Care McKinney, we are happy to offer this advanced contact lens option for our patients in McKinney TX.
What Are Scleral Lenses?
Standard contact lenses are designed to sit on top of the corneas, covering the area extending out to the iris. While these lenses are both comfortable and effective for many people, they may not be adequate for eyes that have specific needs or issues. For instance, standard contacts can aggravate dry eye, adding to the irritation of this condition. Ordinary soft contacts may be no match for corneal irregularities because they're designed to conform to the wearer's corneal curvature. Keratoconus, a condition that causes the corneas to bulge outward, is a good example of a condition that can prove too severe for ordinary contacts to correct.
Scleral lenses solve this problem by not sitting on the corneas at all. Instead, they "vault" right over the corneas, with their edges resting on the white of the eye, or sclera. These rigid lenses thus provide a consistent curve that totally compensates for any irregularities underneath. They also provide a natural reservoir for tears, lending more moisture to chronically dry eyes.
Are Scleral Lenses Right for You?
You can get scleral lenses in a variety of sizes, ranging from the full-sized lenses (up to 24 millimeters in diameter) through mini-scleral, semi-scleral, and finally corneo-scleral designs (as small as 12.9 millimeters). You may be a good candidate for one of these options if you have:
- Dry eye (or underlying conditions that predispose you to it)
- Severe astigmatism
- Corneal irregularities resulting from eye surgery
- Inflammatory corneal diseases
Don't let the size of these lenses intimidate you. Once you get used to inserting, wearing, and removing them, you may find that your new scleral lenses are actually more comfortable than corneal lenses. This is because the tissue of the sclera is less sensitive than the super-sensitive corneal tissues.
