Why Do Scleral Lenses Work for Dry Eye?

Scleral lenses are a unique type of contact lens that are used as a treatment to restore vision to people who suffer from dry eye, keratoconus, radial keratotomy, corneal transplants, or any other condition that causes irregularities of the corneal surface.

Today, we’ll focus on how scleral lenses can help those who experience dry eye. Symptoms include irritation, burning, light sensitivity, excessive tearing, and blurry or fluctuating vision. Patients have dry eye for a variety of reasons including low-grade inflammation, systemic conditions, eyelids that do not close completely, lack of tear production, lack of oil production, as well as scarring or irregular corneas due to conditions such as Ocular Cicatricial Pemphigoid.

How can scleral lenses help treat dry eye? Unlike traditional contact lenses, scleral lenses rest on the white part of the eye (the sclera) and do not touch the cornea, where most dry eye symptoms are felt. Here are a few reasons why scleral lenses are so effective in treating dry eye:

  1. Comfort: Scleral lenses create a barrier between the cornea and the environment. They are filled with saline before insertion, providing a cushion of fluid that reduces irritation and discomfort.

  2. Hydration: The fluid layer created by scleral lenses keeps the eye hydrated, reducing the symptoms of dry eye, such as itching, burning, and redness.

  3. Protection: Scleral lenses protect the cornea from environmental irritants, such as dust, wind, and glare.

  4. Improved Vision: Scleral lenses can improve vision for those with dry eye by creating a smooth, uniform surface for light to pass through, reducing distortion and blurry vision.

  5. Versatility: Scleral lenses can be customized to meet the individual needs of each patient, making them a versatile option for those with dry eye.

In conclusion, scleral lenses offer a unique and effective solution for those suffering from dry eye syndrome. By providing comfort, hydration, protection, improved vision, and versatility, scleral lenses can greatly improve the quality of life for those with dry eye.
