Abstract
Compositions and methods for facilitating the formulation and closure of a corneal flap during LASIK surgery are described. The compositions and methods are based on the use of one or more viscosity-enhancing agents (e.g., chondroitin sulfate) to provide an ophthalmic irrigating solution with improved coating properties and prolonged dwelling time on the cornea, thereby providing lubrication for the microkeratome used to form the corneal flap, reduce corneal epithelial abrasions, and help to produce smooth and consistent cuts with the microkeratome blade.
