[From the introduction]
Large diameter contact lenses that have their resting point beyond the corneal borders are believed to be among the best vision correction options for irregular corneas; they can postpone or even prevent surgical intervention as well as decrease the risk of corneal scarring. For true clearance of the cornea, without any mechanical involvement, it seems advised to avoid contact between the lens and the cornea by bridging over it. A few years ago, only a handful of very specialized lens fitters around the world were capable of fitting scleral lenses successfully, and only a few manufacturers were making scleral lenses. Now many contact lens manufacturers have scleral lens designs in their arsenal. Improved manufacturing processes allow for better design, make lenses more reproducible and decrease costs, which combined with better lens materials has contributed to better ocular health, longer wearing time and ease of lens fit. This, in return, has broadened up the indication range for scleral lens fitting. But scleral lens fitting is still in its infancy, and this scleral lens case report series will share and discuss knowledge gained by practitioners who regularly work with these lenses.
