Scleral lenses
A scleral lens is a rigid contact lens that vaults the entire cornea in saline solution and sits on the sclera. The fact that this lens only touches the sclera is the reason why this lens has amazing comfort. The sclera is the white tissue around the color part of the eye. This tissue is not very sensitive when compared to the cornea. By, vaulting the front surface of the eye we create a new refractive surface that is smooth and uniform. This is great for patients with:
1) Keratoconus
2) LASIK, corneal ectasias
3) Corneal transplants
4) High astigmatism
5) Dry eye
Because of the material of the scleral lens, the insertion and removal technique is very different from a soft contact lens, or even a rigid gas permeable lens. The way we insert a scleral lens requires a DMV and to remove the contact lens requires a plunger. Both are very easy to use.
By following these simple steps, your scleral lens experience will be comfortable and stress-free!
Follow Instructions for Proper Care
Scleral lenses are made from materials that are classified as "Gas Permeable." Only use cleaning, handling, or soaking solutions that are approved for gas permeable lenses. Preservative-free saline application solutions are intended for filling the lens and applying only, they are not intended for cleaning or storage of the lens. Always keep solutions separate and use only clean, fresh solutions for all care of scleral lenses. Be mindful not to switch left and right lenses. The lenses you're fit to are highly customized and are meant for individualization.
Use Correct Hygiene Techniques
It is very important to handle your scleral lenses in a clean environment. Always use clean tools and cases. Before handling anything, always wash your hands thoroughly with soap that does not contain moisturizer. Dry hands with a clean towel.
Pay Attention to the Health of Your Eyes
Be sure to evaluate the health of your eyes from time to time. This includes looking for any signs of redness, swelling, and inflammation that may indicate you need to be seen again by your optometrist for a possible adjustment of your fit. It's completely normal at first to have a slight impression ring where the lens is sitting. This will fade away quickly. Always consult your optometrist if you have any questions or concerns.
