  • Patent number: 6117907
    Abstract: Post-operative method for the treatment of ocular pain following corneal reprofiling surgery by topical administration of an ophthalmic nonsteroidal solution and an ophthalmic steroidal composition. The nonsteroidal solution comprises a non-steroidal anti-inflammatory agent such as diclofenac sodium and the steroidal composition contains a corticosteroid such as fluorometholone. These ophthalmic medicaments when used in combination reduce the post-operative pain particularly associated with phototherapeutic keratectomy and photorefractive keratectomy performed with an excimer laser and promote re-epithelialization over the reprofiled corneal surface.
