Abstract:Scleral contact lenses are large diameter, rigid, gas-permeable contact lens that does not contact the cornea and are completely supported by the sclera. In the past, scleral contact lenses were used to treat severe eye diseases and a few doctors were authorized to prescribe them, but with the update of lens materials and design, the safety of the lens is improving, and its application is becoming more and more widespread. Scleral contact lenses can provide clear and stable vision for patients with corneal irregularity by neutralizing optical aberration, and can also effectively treat various ocular surface diseases. Scleral contact lenses have become a new treatment method for ocular surface diseases. Although scleral contact lenses have been proven to be effective in clinical practice, its preparation and use are complex and require long-term care and maintenance. In this paper, the characteristics, classification, development, clinical application and adverse reactions of scleral contact lenses are described, so as to further understand the current research status of the lenses and provide reference for the application of them.
