Scleral Lenses: A Glimpse into Innovative Dry Eye Management

Dry Eye Disease (DED) is a common and often chronic condition that can significantly impact an individual's quality of life. Characterized by insufficient tear production or poor tear quality, it leads to symptoms such as burning, stinging, itching, redness, and blurry vision. Traditional treatments like artificial tears, warm compresses, and prescription eye drops offer relief but may not provide long-lasting solutions for all patients. In recent years, scleral lenses have emerged as a promising innovation in the management of dry eye disease, offering both symptom relief and improved ocular health. Let’s explore the benefits and applications of scleral lenses in managing dry eye disease.

Understanding Scleral Lenses (Custom Contact Lenses)

Scleral lenses are specialized contact lenses that are larger in diameter than traditional soft or rigid gas permeable (RGP) lenses. These lenses vault over the entire cornea, resting on the white of the eye (sclera) and forming a fluid-filled reservoir between the lens and the cornea. This unique design provides several advantages for individuals suffering from dry eye disease:

  1. Moisture Retention: Scleral lenses trap a layer of saline solution between the lens and the cornea, creating a stable and moisturizing environment that helps to alleviate dryness and discomfort. This reservoir of liquid acts as a constant source of hydration for the ocular surface.
  2. Protection: Scleral lenses protect the cornea from environmental irritants and reduce friction between the eyelids and the ocular surface, making them an excellent choice for patients with severe dry eye or ocular surface diseases.
  3. Improved Vision: The rigid material used in scleral lenses can help correct refractive errors, including astigmatism, providing improved visual acuity. This is particularly beneficial for patients who experience vision disturbances due to dry eye disease.
  4. Extended Wear Time: Scleral lenses can often be worn for more extended periods than traditional contact lenses without discomfort. This extended wear time can be especially helpful for individuals with chronic dry eye who require relief throughout the day.

Applications of Scleral Lenses in Dry Eye Management

Scleral lenses offer various applications in the management of dry eye disease, making them a versatile option for patients with different needs:

  1. Severe Dry Eye: Individuals with severe dry eye often find conventional treatments inadequate. Scleral lenses provide long-lasting relief by maintaining a stable tear film on the ocular surface, reducing irritation and discomfort.
  2. Irregular Corneas: Conditions such as keratoconus, corneal scarring, or post-surgical complications can result in irregular corneas. Scleral lenses can mask these irregularities, providing a smoother optical surface for improved vision and comfort.
  3. Graft-versus-Host Disease (GVHD): Patients undergoing bone marrow or stem cell transplantation may develop severe dry eye symptoms because of GVHD. Scleral lenses can alleviate their discomfort by providing continuous lubrication and protection.
  4. Environmental Sensitivity: People who work in dry, dusty, or windy environments may experience increased dry eye symptoms. Scleral lenses act as a barrier, shielding the eyes from external factors that exacerbate dryness.

Scleral lenses have revolutionized the management of dry eye disease, offering a unique and effective solution for patients who have struggled with traditional treatments. Their ability to provide continuous hydration, protect the cornea, and improve visual acuity makes them an invaluable tool in the armamentarium against dry eye symptoms. However, it's important to note that scleral lenses require proper fitting and ongoing care by a qualified eye care professional. If you're suffering from dry eye disease and haven't found relief with conventional treatments, it may be worth exploring scleral lenses as a potential solution to improve both your comfort and vision. Consult with your eye care specialist to determine if scleral lenses are right for you.
