Scleral lenses are a specialized type of contact lenses that offer exceptional comfort and improved vision for various eye conditions. Unlike standard contact lenses that rest on the cornea, scleral lenses vault over the cornea and rest on the white part of the eye, known as the sclera. Their unique design and larger diameter make them an excellent choice for those who struggle with conventional lenses.
Understanding Scleral Lenses
Scleral lenses are larger than typical gas-permeable lenses, ranging from approximately 14.5 mm to 24 mm in diameter. They are designed to arch over the cornea without making contact with its surface, instead landing on the less sensitive sclera. This design creates a tear-filled vault over the cornea, which not only helps in managing various eye conditions but also provides significant comfort.
Benefits of Scleral Lenses
- Enhanced Comfort: Due to their size and the way they interact with the surface of the eye, scleral lenses distribute pressure more evenly than traditional contacts. This reduces the sensation of lens presence, making them comfortable for extended wear throughout the day.
- Improved Visual Acuity: The liquid reservoir trapped between the lens and the cornea can help correct vision distortions by creating a smoother optical surface. This is particularly beneficial for those with keratoconus or other corneal irregularities, where the cornea’s cone shape causes blurred and distorted vision.
- Protection and Healing: The protective buffer of saline solution can shield the cornea from exposure to air and debris, which is especially advantageous for people with dry eye syndrome or those recovering from corneal surgery.
- Stable Fit: Scleral lenses are less likely to dislodge from your eyes due to their size and the way they fit, making them ideal for sports or other physical activities.
Who Can Benefit from Scleral Lenses?
1. Patients with Keratoconus:
Those suffering from keratoconus, a condition where the cornea thins and bulges outward into a cone shape, can particularly benefit from scleral lenses. The lenses help in creating a smooth refractive surface to improve vision.
2. Individuals with Severe Dry Eyes:
For patients experiencing severe dry eye syndrome, traditional contact lenses may be uncomfortable or even impossible to wear. Scleral lenses can maintain hydration and reduce pain associated with dry eyes.
3. Those with Irregular Corneas:
Conditions such as post-corneal transplant and corneal scarring can lead to irregular corneas. Scleral lenses help by providing a uniform refractive surface to significantly improve visual clarity.
4. Contact Lens Wearers Needing More Comfort:
Individuals who find regular contact lenses uncomfortable due to sensitivity, previous surgery, or other issues may find scleral lenses to be a more comfortable and viable option.
Fitting and Care for Scleral Lenses
Getting fitted for scleral lenses involves a detailed and precise process. It typically requires advanced imaging and measurement to customize the lenses to the unique contours of each eye. Here’s what to expect:
1. Customized Fitting: Due to the larger size and specific fitting requirements, scleral lenses require a specialized and customized fitting. This ensures that the lenses not only fit properly but also provide the maximum comfort and vision correction.
2. Trial and Adjustment: Fitting scleral lenses might require several visits to an eye care professional to refine the lens fit and prescription. This process is crucial to achieving the best results.
3. Proper Care Routine: Scleral lenses require a strict cleaning and maintenance routine. They need to be cleaned and disinfected each day they are worn to prevent infections and maintain the quality of the lenses. Special solutions may be recommended by your eye care provider.
The Process of Wearing Scleral Lenses
1. Application: Inserting scleral lenses involves placing a prescribed amount of sterile saline solution into the bowl of the lens before placing it onto the eye. This technique may take practice to perfect but is essential for creating the liquid reservoir that ensures comfort and clear vision.
2. Daily Wear: While scleral lenses can be worn all day, it’s essential to follow the wearing schedule prescribed by your eye care professional to prevent complications.
3. Regular Check-ups: Regular appointments with your eye care provider are necessary to monitor the health of your eyes and the condition of your lenses.
Scleral lenses represent a significant advancement in the field of optometry, offering a superior solution for individuals who require vision correction and suffer from conditions that make traditional lenses unsuitable. Whether due to irregular corneas, severe dry eyes, or the need for enhanced comfort during physical activities, scleral lenses provide a stable, protective, and comfortable option that can dramatically improve the quality of life for many. If you think scleral lenses might be right for you, a consultation with an eye care professional trained in fitting scleral lenses is the best next step to explore this innovative vision solution.
