An improved viscoelastic composition useful in the performance of ophthalmic surgical procedures and especially cataract procedures is disclosed. The embodiments of the composition comprise combinations of sodium hyaluronate and chondroitin sulfate and exhibit an improved rheological profile.

Combinations of viscoelastics for use during surgery

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.

Ophthalmic lubricating solution adapted for use in lasik surgery

Disclosed are viscoelastic compositions and methods of their use in surgical and non-surgical packing and in effecting drug delivery, especially in conjunction with trauma to of disorders of the ear.
