Abstract
Ocular lubricant solutions are described. The solutions are adapted to facilitate the formation of a corneal flap during LASIK surgery. The solutions contain one or more viscosity enhancing agents (e.g., chondroitin sulfate) in a substantially salt-free, ophthalmically acceptable vehicle. Methods of lubricating the cornea to facilitate flap formation are also described.
