Why Choose Custom Scleral Contact Lenses? A Guide to Their Advantages and Fit

When it comes to correcting vision, many people are familiar with traditional glasses or soft contact lenses. However, for those who struggle with complex vision problems, custom scleral contact lenses offer a unique solution. Scleral lenses are larger, rigid gas permeable lenses that provide numerous benefits, particularly for individuals with irregular corneas or specific eye conditions.

What Are Scleral Lenses?

Scleral lenses are large-diameter, rigid gas permeable (RGP) contact lenses designed to rest on the white part of your eye (the sclera), rather than directly on the cornea. These lenses are larger than regular contacts, typically covering the entire corneal surface and extending over the sclera. Because of this unique design, scleral lenses create a tear reservoir between the lens and the cornea, which can significantly improve vision and comfort for people with a variety of eye conditions.

Enhanced Comfort and Stability

One of the most significant advantages of custom scleral lenses is their comfort. While traditional contact lenses can cause discomfort for individuals with irregular corneas, custom scleral lenses create a smooth, even surface for the eye. By vaulting over the cornea, they alleviate the pressure points that can cause irritation with regular lenses. Additionally, the lens creates a cushion of fluid between the lens and the cornea, which can soothe dry eyes, reduce irritation, and improve comfort.

Superior Vision Correction

Scleral lenses are particularly beneficial for people with irregular corneas, such as those with keratoconus, astigmatism, corneal scars, or post-surgical changes (e.g., after a corneal transplant). These conditions cause the cornea to be misshapen, which can lead to blurry vision. Scleral lenses create a new, smooth optical surface, helping to correct even the most complex vision issues. Custom scleral lenses are designed specifically for the individual’s eye measurements, providing the best fit and optimal vision correction.

Improved Eye Health

Since scleral lenses rest on the sclera and not directly on the cornea, they put less pressure on the cornea compared to regular contact lenses. The tear reservoir between the lens and the cornea also helps to keep the eye hydrated, which is especially important for people with dry eyes or conditions that reduce tear production. Scleral lenses protect the cornea from further damage by acting as a barrier between the eye and environmental irritants, such as allergens and pollutants.

Long-Lasting Wear Time

Custom scleral lenses can provide extended wear time for those who may struggle with other types of lenses. The ability to retain moisture and provide stability throughout the day makes scleral lenses ideal for people who need to wear contacts for long periods. With proper care and maintenance, scleral lenses can last for months or even years, making them a cost-effective solution in the long run.

Better Option for Dry Eyes

For individuals suffering from severe dry eye, custom scleral lenses offer a great alternative to traditional lenses or glasses. The lens forms a cushion of tears between the lens and the cornea, effectively creating a "moisture chamber" that keeps the eyes hydrated throughout the day. This feature can be particularly helpful for people with Sjögren’s syndrome, post-surgical dry eyes, or other conditions that lead to chronic dry eyes.

The Scleral Lens Customization Process

Fitting scleral lenses requires a high level of precision. The process typically involves:

•       Comprehensive Eye Exam: Your eye doctor will start with a thorough eye exam to assess the health of your eyes and the specific condition affecting your vision.

•       Custom Measurements: Your doctor will take detailed measurements of your cornea and the surrounding eye surface to ensure the lenses fit properly. This may include mapping the curvature of your cornea using specialized instruments.

•       Lens Fitting and Trial: After selecting the right size and design, trial lenses will be placed on your eyes to assess their fit. Your doctor will check for any discomfort or issues with vision and make necessary adjustments to the lens design.

•       Final Adjustments: Once your custom lenses are made, you will return for a follow-up visit to ensure that the lenses fit properly and are providing optimal vision and comfort.
