Scleral Contact Lenses: Customized Vision
Have you been informed in the past that you are not a candidate for contact lenses, or that you cannot wear contact lenses because of an irregular cornea, dry eye, or another issue? If so, you may want to inquire about pursuing scleral contact lenses. They are a customizable lens that can worn by a greater number of individuals.Schedule An Exam Our Optometrists

Scleral Contact Lenses: What Are They?
Scleral contact lenses are large-diameter gas permeable contact lenses specially designed to span the entire corneal surface and rest on the "white" portion of the eye (sclera). The result is that the scleral lenses functionally replace the irregular cornea with a perfectly smooth optical surface to correct vision problems caused by keratoconus or other corneal irregularities. The gap formed between the cornea and back surface of a scleral lens becomes a reservoir for a saline solution that provides comfort for people with severe dry eyes, who otherwise could not tolerate contact lens wear.Schedule A Scleral Contact Lens Fitting

Scleral Contact Lenses: Types & Uses
Scleral contacts are comparatively larger than standard gas permeable (GP) contact lenses and have a diameter equal to or greater than soft contact lenses. With the average cornea being approximately 11.8 millimetres in diameter, even small scleral contact lenses cover the entire corneal surface. Corneo-scleral lenses often are a good choice for people who require larger-than-normal GP lenses for greater comfort. They also are frequently used when contact lenses are needed following corneal refractive surgery to correct irregular astigmatism. Larger scleral lenses are great for conditions such as keratoconus, chronic dry eyes, and severe ocular surface disease that may benefit from a large tear reservoir. That is because the gap created between lens and cornea would have a greater capacity to hold fluid (i.e., saline) and span large corneal variances.Schedule A Scleral Contact Lens Fitting

Scleral Contact Lenses: What To Expect.
Scleral contact lenses are tailor-made for each patient. Accordingly, fitting scleral contacts requires greater expertise, technology (i.e., corneal topographer) and more time than fitting standard soft or gas permeable contact lenses. Also, because scleral contact lenses are a precision product, adjustments to lens parameters may be needed and addtional be made and exchanged. The complete fitting process can require several visits to determine the optimal lens for both eyes. Mastering inserting and removing scleral lenses may also take some practice, even for experienced contact lens wearers. This is due to the larger lens size and the need to maintain a fluid reservoir under the lenses. Because of the expertise needed to fit and manufacture scleral lenses, costs are noteably greater than compared to fitting soft or GP contact lenses.Schedule A Scleral Contact Lens Fitting
