[Double-blind study on 3 parallel groups of 2 formulations of 0.1% indomethacin and 0.1% diclofenac in preventing and controlling inflammation after cataract surgery].

PURPOSE

To evaluate the efficiency and safety of LCM 1110 eyedrops, a new 0.1% indomethacin formulation, compared with the registered 0.1% indomethacin solution and with 0.1% diclofenac, in the management of post cataract surgery inflammation.

METHODS

A total of 352 patients randomly assigned to LCM 1110 (n = 116), to indomethacin (n = 121) or to diclofenac (n = 115) were included in this three-arm, prospective, multicenter and double-masked trial, after giving written informed consent. They were given preoperatively 1 drop QID the day before surgery, 5 drops within 2 hours prior to operation then 1 drop QID for 1 month. Cataracts were extracted by either extracapsular or phacoemulsification methods, with PC-IOL implantation. The main efficacy evaluation was based on the assessments of anterior chamber cells and flare at days 1, 7 and 30 following surgery. Symptoms, other objective signs and IOP were recorded.

RESULTS

Cellular and proteinic Tyndall phenomenon did not significantly differ in the 3 groups, at any of the post surgical assessments. Clinical symptoms and visual acuity improved similarly. IOP was not adversely affected by any drug. Compared with subjects having received LCM 1110, diclofenac-treated patients experienced a superficial punctuate keratitis more frequently. Tolerance of instillation, measured by a visual analogic scale, was best improved by LCM 1110 followed by the indomethacin solution and by diclofenac (LCM 1110-diclofenac; p = 0.004).

CONCLUSION

These data suggest that LCM 1110, a new 0.1% indomethacin ophthalmic solution, appears to be a safe promising agent for the control of postoperative inflammation.
