Scleral contact lenses
At Vivid Sight Optometry we strive to bring the most optimal vision to patients struggling with corneal eye disease and other irregularities. Dr. Villa specializes in a variety of specialty hard-to-fit contact lenses including scleral lenses. Scleral lenses are rigid contact lenses that vault over the cornea and rest on the sclera (white part of the eye). This technology creates a round smooth surface to allow for superior comfort and vision. Scleral contact lenses are indicated for patients with the following conditions:
- Keratoconus
- Irregular astigmatism
- corneal scarring
- dry eye syndrome (Sjogren's syndrome)
- Pellucid Marginal Degeneration
- Post- Lasik or other refractive procedures (RK)
- Steven Johnson Syndrome
- Burn injuries
Importance of the Sizing Process
The sizing portion is vital for matching you with the correct contact lens prescription. A poorly fit contact lens may not stay in your eye properly. Additionally, it could feel uncomfortable. Plus, the contact must stay in the proper position to optimize your vision.
This is especially the case if you have astigmatism. A contact lens for astigmatism has different focusing powers in different portions of the contact. If it doesn't stay in place, you may experience blurry vision or just not receive the optimal vision correction from the corrective lenses.
If you choose Ortho-K, a special fitting for gas-permeable lenses that you sleep in, they require a specialized fitting process to ensure they reshape your eyes in a manner that corrects your vision.
Contact Lens Fitting Process with Vivid Sight Optometry
During a contact lens fitting, you look into a machine that gathers information about the dimensions of your eyes. The process is painless and takes only a few moments to complete. The machine, known as an auto-refractor, takes measurements of your eyes. It does so by shining light into your eyes and evaluating how the light reflects at different angles.
It's possible you'll need to have another test as well to fit you for contact lenses, which uses a keratometer. A keratometer is a machine that assesses the shape of your cornea. It's an evaluation used particularly for people with astigmatism or corneal problems. It determines if your cornea is more round or flat. We are able to fit patients with GP and scleral contact lenses for patients with irregular corneas such as keratoconus, RK patients, ocular surface disease, etc.
