Abstract
|
|
|
|
Scleral contact lens is defined as a lens fitted to vault over the entire cornea, including the limbus, and to land on conjunctiva overlying the sclera. Scleral contact lens-associated adverse events or complications have not been frequently reported, as the modern scleral contact lens has high oxygen permeability. However, complications can occur anytime during long-term scleral contact lens wear. Infection is the most important complication which can lead to permanent visual loss. In addition, hypoxia, problems coming from asymmetric scleral shape, lens seal-off, conjunctival prolapse, limbal bearing, and mid-day fogging are unique problems associated with scleral contact lens wear.
