Scleral contact lenses have become a popular choice for individuals with specific eye conditions, such as keratoconus, extreme dry eyes, or those who have undergone refractive surgeries like Post Radial Keratotomy (RK). These lenses provide improved vision and comfort by vaulting over the cornea and resting on the sclera, the white part of the eye.
What are Scleral Contact Lenses?
Scleral contact lenses are large-diameter contact lenses that cover the entire cornea and extend onto the sclera. Unlike traditional contact lenses, which rest directly on the cornea, scleral lenses create a tear-filled reservoir between the lens and the cornea. This reservoir helps to provide a smooth optical surface, reducing vision distortions caused by irregular corneal shapes and improving visual acuity.
Scleral lenses offer several advantages over traditional contact lenses. They provide better stability on the eye, making them less likely to dislodge or move during activities. The tear-filled reservoir beneath the lens also helps to keep the eye lubricated, making them an excellent choice for individuals with severe dry eye conditions. Additionally, the larger size of scleral lenses makes them more comfortable to wear, as they do not come into direct contact with the sensitive corneal surface.
Common Issues with Scleral Contact Lenses
While scleral contact lenses offer numerous benefits, they can come with some common issues that users may encounter. These issues include lens fogging, discomfort, and challenges with lens insertion and removal.
One of the primary concerns with scleral lenses is lens fogging. Lens fogging occurs when the lens surface becomes coated with moisture, leading to reduced vision and discomfort. Factors such as temperature changes, humidity, and certain activities can contribute to lens fogging. To overcome this challenge, it’s essential to follow proper lens cleaning and care techniques, as well as utilize anti-fog solutions or drops.
