Guide for Successful Scleral Lens Fitting

To date, scleral contact lenses have been known only as large-sized contact lenses with an uncomfortable fit, intended exclusively for patients with severe ocular surface diseases.

In this review article, we aim to discuss scleral contact lenses, including their indications and fitting methods.
