Scientific titleNepafenac and prevention of cystoid macular edema (CME) after cataract surgery in patients receiving latanoprost: a randomised controlled trial
Study objectivesTo evaluate whether there is a potential benefit, in term of cystoid macular edema (CME) prevention, in the administration of nepafenac and/or discontinuation of latanoprost in patients receiving latanoprost undergoing uneventful cataract surgery by phacoemulsification and intraocular lens (IOL) implantation.
Ethics approval(s)Institutional Review Board, Faculty of Medicine, Chulalongkorn University, approved on the 14th October 2010 (ref: COA no.514/2010 IRB no.241/53)
Health condition(s) or problem(s) studiedCystoid macular edema (CME)
InterventionOnly eyes received 0.005% Latanoprost at least 1-month prior to a planned phacoemulsification with PC-IOL implantation, would be included, as indicated in the inclusion criteria. Subjects that were met with inclusion and exclusion criteria will be randomly assigned using block-of-six to one of the following three groups:
Group 1: 0.005% Latanoprost ed
Group 2: 0.005% Latanoprost ed and 0.1% Nepafenac ed
Group 3: artificial tears as Latanoprost placebo

0.005% Latanoprost and Latanoprost placebo are masked and given once daily before bedtime, starting from the first day after cataract surgery until the study endpoint at the 10th post-operative week. 0.1% Nepafenac (Nevanac; Alcon Inc., Fort Worth, Tx, USA) is given 3 times daily 3 days before surgery until the 3rd post-operative week.

All subjects undergo a clear corneal incision, phacoemulsification, and intraocular lens implantation using an acrylic foldable IOL (AcrysofIQ; Alcon Inc., Fort Worth, Tx, USA). Post-operative regimen includes 0.5% Moxifloxacin (Vigamox; Alcon Inc., Fort Worth, Tx, USA) given qid for 1 month, and 1% Prednisolone acetate (Pred-Forte; Allergan Inc., Westport, Ireland) given q2h x1d, qid x4wk then tid x4wk.
Intervention typeDrug
PhasePhase III
Drug / device / biological / vaccine name(s)Nepafenac, latanoprost
Primary outcome measure(s)

Difference in incidence of post-operative CME - detected with OCT and measured up to 10 weeks accumulatively - between either approaches: discontinuation of Latanoprost or continuing Latanoprost but with the administration of Nepafenac, compared with a group of patients who continue to use Latanoprost as previously used pre-operatively (control group or non-intervention group).

Key secondary outcome measure(s)

Occurrence of post-cataract surgery CME in the non-intervention group (control group) detected by OCT.
