Characteristics of Scleral Lenses and Patient Selection

Abstract

Scleral lenses lies on the sclera, not the cornea, and help to improve vision in cases of irregular cornea or ocular surface diseases, and to treat ocular surface diseases with moisture to the cornea. The fitting rate of scleral lenses is increasing due to improvements in scleral lens materials and advancements in anterior segment imaging equipment. In order to successfully fit scleral lenses, it needs to understand the structure and principles of scleral lenses and select appropriate patients. There is no absolute contraindication of scleral lenses, but regular follow‐up is recommended for patients who require caution.
