Abstract
Purpose:
To compare the effects of topical diclofenac and betamethasone on postoperative inflammation after combined sutureless cataract and vitreoretinal surgery in patients with macular hole (MH), epiretinal membrane (ERM), diabetic macular edema (DME), and rhegmatogenous retinal detachment (RRD).
Methods:
The study involved 180 eligible eyes that underwent the combined surgery, followed by treatment with topical diclofenac (n = 100) or betamethasone (n = 80) for 12 weeks. Maximum postoperative inflammation index (maxPOI), assessed by laser flare–cell meter, and intraocular pressure (IOP) were monitored. The relationships between maxPOI and total operation time or number of endophotocoagulations during surgery were investigated.
Results:
Postoperative inflammation peaked at 2 weeks and decreased thereafter in all 4 diseases, without significant differences between 2 treated groups. Postoperative IOP in MH and ERM was significantly higher in the betamethasone group. In DME and RRD, a greater number of endophotocoagulations increased maxPOI in both diclofenac and betamethasone groups, while longer operation time increased maxPOI only in diclofenac groups.
Conclusions:
In MH and ERM, topical diclofenac and betamethasone equally suppressed postoperative inflammation after the combined surgery, although diclofenac better controlled postoperative IOP. In DME and RRD, both drugs were equally effective in suppressing inflammation and controlling IOP, but diclofenac showed weaker suppression following longer operation.
