- Brief summaryRationale:
Cataract extraction is the most frequently performed surgical intervention. One of the most common causes of poor visual acuity after cataract surgery is the development of postoperative clinical (cystoid) macular edema ((C)ME). Several treatment options have been investigated, but a uniform treatment protocol does not exist. The current treatment strategies range from no to very intensive treatment with no strategy showing unambiguous benefits. However, based on our experience and extensive literature review, it is likely that a treatment using local application of a corticosteroid and a non-steroidal anti-inflammatory drug will be optimal. Therefore, the efficacy of treatment of CME with a combination of these types of drug will be investigated.

Objective:
To study the efficacy of treatment with Nevanac in combination with Pred Forte of Cystoid Macular Edema after phacoemulsification.

Study design:
Prospective randomized double-masked placebo-controlled clinical trial.

Study population:
Patients diagnosed with clinical CME within three months after phacoemulsification.

Intervention:
Group 1: Placebo eyedrops in two separate phials.
Group 2: 6 weeks treatment of nepafenac 0,1% eye drops 3 d.d., plus prednisolone acetate 1% eye drops 3 d.d.

Main study parameters/endpoints:
Before treatment and 4, 8, 12, 20 and 52 weeks after treatment has started:
1. Prevalence of (C)ME;
2. Best Corrected Visual Acuity by ETDRS;
3. Inflammation parameter (Laser flare count) by Laser Flare Meter;
4. Thickness of the macula, by OCT.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness:
There are no risks involved for patients in group 1; possible side effects of medication used in this study (group 2) can be found in the respective SPC's. Six study-related visits are scheduled, which will take 30 minutes each. Measurements are not invasive; burden is low.
