Abstract:

Dry eye is a chronic ocular surface disease caused by multiple factors，which seriously affects patients′visual function and quality of life.Scleral lenses，as an innovative treatmentmethod，can form a＂reservoir＂on the ocular surface to maintain corneal moisture，reduce mechanical damage，and promote corneal healing.It has been shown that scleral lenses have significant therapeutic effects in the clinical treatment of dry eye，which can effectively improve patients′vision，reduce tear osmolarity，significantly alleviate dry eye symptoms，and enhance patients′quality of life.Scleral lenses are suitable for patients with moderate to severe dry eye，especially for those who have not responded well to traditional treatments.For instance，in cases of severe dry eye caused by chronic graft-versus-host disease，exposure keratitis，and Stevens-Johnson syndrome，wearing scleral lenses can provide physical protection，thereby effectively alleviating dry eye symptoms.In recent years，with the continuous exploration and development in design technology，material science and application fields，the application prospects of scleral lenses in dry eye treatment have become increasingly broad.Thewider application of scleral lenses in clinical practice can provide a safer and more effective treatment for dry eye patients，and further promote the progress and development of dry eye treatment field.
