Effect of anti-inflammatory regimen on early postoperative inflammation after cataract surgery

To investigate whether a combination of topical nonsteroidal anti-inflammatory drugs (NSAIDs) and steroids were superior in controlling early postoperative inflammation after cataract surgery compared with topical NSAIDs alone and with dropless surgery where a sub-Tenon depot of steroid was placed during surgery.

Department of Ophthalmology, Rigshospitalet-Glostrup, Denmark.

Prospective randomized controlled trial with masked statistical analyses.

Patients undergoing phacoemulsification for age-related cataract were randomized to 1 of 5 regimens: ketorolac and prednisolone eyedrops combined (Pred+NSAID-Pre [control group] and Pred+NSAID-Post group) vs ketorolac monotherapy (NSAID-Pre and NSAID-Post groups) vs sub-Tenon depot of dexamethasone (dropless group). Drops were used until 3 weeks postoperatively, starting 3 days preoperatively in the Pre groups and on the day of surgery in the Post groups. Aqueous flare was measured at baseline and 3 days postoperatively.

Four hundred fifty-six participants, with a mean age of 72.1 (SD 7.0) years and 283 (62%) women, were included. Flare increased significantly more in the dropless group compared with the control group (Pred+NSAID-Pre), but none of the other groups differed significantly from the control group. Intraocular pressure decreased in all groups but significantly less in groups receiving prednisolone eyedrops (Pred+NSAID-Pre and Pred+NSAID-Post groups) compared with NSAID monotherapy and dropless groups. No differences in postoperative visual acuity were found compared with the control group.

No differences were found between groups randomized to NSAID monotherapy or combination of NSAID and steroid in controlling early inflammation after cataract surgery, but sub-Tenon depot of dexamethasone was less efficient. Initiating prophylactic eyedrops prior to surgery did not influence early postoperative anterior chamber inflammation.
