What Are Scleral Contact Lenses?
Scleral contact lenses are typically gas permeable contact lenses, but new hybrid scleral lenses are now availbile. The lenseshave a larger diameter than a soft contact lens, ranging in size from 14mm to 20mm. As a result of this larger size, they sit on the scleral, the white of the eye, and improve the comfort for the wearer by removing the pressure on the sensitive cornea.
Who Can Benefit from Scleral Contact Lenses?
Scleral contact lenses are used for a wide range of patients who have corneal or ocular surface abnormalities, commonly due refractive surgery. Keratoconus eyes are another example of eyes that can benefit from these contacts. Also, patients with chronic dry eyes or who are at risk of having the contact dislodged from the eye due to athletic activities can use these lenses.
Adjusting to Scleral Contact Lenses
If your doctor believes that you could benefit from scleral contact lenses, and you have been wearing soft contact lenses, you should be prepared for a period of adjustment. These lenses will feel different than soft contact lenses, and they require a unique application and removal process. However, if your soft lenses have been irritating your eyes, you may find relief by making the switch, which creates a less difficult adjustment period. However with new technology hybrid scleral contact lenses are now available to provide better comfort and optics.
How to Apply and Remove Scleral Contact Lenses
Scleral contact lenses are applied using a bulb shaped plunger that applies the lens to the surface of the eye. You may need to fill the lens with fluid before application, as directed by your doctor. When you are ready to remove the lens, attach the plunger to the edge of the lens and tilt it out of the eye. Throughout this process, you must use one hand to hold both lids completely out of the way to avoid a problem.
How to Get Scleral Contact Lenses
If you think you need scleral contact lenses, talk to your eye care professional. You will be able to get the lenses through your eye doctor, but only after a thorough evaluation to determine the proper lenses that will help you, followed by careful instruction on proper care and use of the lenses.
