Topical ketorolac tromethamine in the reduction of adverse effects of laser in situ keratomileusist.

PURPOSE : To evaluate whether topical ketorolac tromethamine can reduce the adverse effect of laser in situ keratomileusis (LASIK). DESIGN: A prospective randomized controlled clinical study. PARTICIPANTS: Nineteen patients who underwent bilateral simultaneous LASIK performed at Siriraj Hospital. INTERVENTION: Patients received two drops of ketorolac tromethamine in one eye immediately after surgery. MAIN OUTCOME MEASURES: Symptoms of tearing, photophobia, foreign body sensation and pain were evaluated at 30 minutes, 6 hours and 24 hours. RESULTS: There was no statistically significant difference in symptoms at 30 minutes. At 6 and 24 hours, ketorolac-treated eyes had significantly fewer symptoms compared to non-treated eyes. CONCLUSIONS: Ketorolac tromethamine reduces some unfavorable symptoms within the first 24 hours after LASIK.

Amniotic membrane transplantation for ocular surface reconstruction.

OBJECTIVE: To study the efficacy of amniotic membrane transplantation in various indications for ocular surface reconstruction. METHOD: Amniotic membrane transplantations were performed in 140 eyes (130 patients) for ocular surface reconstruction. The indications for the corneal group were limbal stem cell deficiency, bullous keratopathy, persistent epithelial defect, band keratopathy, prosthesis, corneal ulcer and acute chemical burn. The indications for the conjunctival group were grafts for pterygium, conjunctival tumors, symblepharon, and covering the scleral graft. RESULTS: Success was noted in 75.7 per cent (106/140) eyes, partial success in 17.9 per cent (25/140) eyes, and failure in 6.4 per cent (9/140) eyes for a mean follow-up of 6.6 months (1-19 months). The success and partial success rate were 80.6 per cent (54/67), 14.9 per cent (10/67) in the corneal group and 71.2 per cent (52/73), 20.6 per cent (15/73) in the conjunctival group. CONCLUSION: Amniotic membrane transplantation can solve some difficult ocular surface problems, and can be used to promote epithelial healing, reduce inflammation and scarring.
