Abstract

Results: The natural peak of pain was located between 24 and 36 hours. Initially, the degree of pain reduction was constant for both NSAIDs; it dropped after 24 hours and 36 hours in the ketorolac group and the diclofenac group, respectively. The postoperative time-serial pattern of the pain score changed in the diclofenac group but not in the ketorolac group compared with the pattern in the ofloxacin-treated eye. The visual outcome was not affected by either NSAID, and significant complications were not noticed for a mean of 7 months.

Methods: Ninety-four patients were randomly assigned to 2 groups: ketorolac group (ketorolac 0.5% in 1 eye and ofloxacin 0.3% in the other eye) and diclofenac group (diclofenac 0.1% in 1 eye and ofloxacin 0.3% in the other eye). One drop of each ophthalmic drug was applied 3 times to each eye 30 minutes before PRK. No other NSAID or steroid was prescribed until 4 days after PRK. The patients were asked to score the postoperative pain in each eye with a visual analog scale at 6, 18, 24, 36, 48, 72, and 96 hours.

Conclusions: The duration and pattern of the action may vary according to types of NSAIDs. Preemptive topical diclofenac 0.1% was a safe and effective method for post-PRK pain control.

Purpose: To investigate changes in the pain-suppressing potency of 2 preoperatively applied topical nonsteroidal antiinflammatory drugs (NSAIDs) after photorefractive keratectomy (PRK) using a time-serial pain-scoring system.

Design: Comparative case series.
