Title: Comparison of Ketorolac Tromethamine 0.4% and Nepafenac 0.1% for the Prevention of Cystoid Macular Edema After Phacoemulsification: Prospective Randomized Double-masked Study
Brief Summary: To compare the anti-inflammatory efficacy of ketorolac of tromethamine 0.4% and nepafenac 0.1% eye drops for prophylaxis of cystoid macular edema (CME) after small-incision cataract extraction.


Options:
A: Inclusion Criteria:

* Planned cataract extraction by phacoemulsification with the implantation of a posterior chamber intraocular lens (IOL) into the lens capsule.
* History of Type 1 or Type 2 diabetes.
* History of nonproliferative diabetic retinopathy (NPDR), mild, moderate, or severe, in the study eye as defined by the International Clinical Diabetic Retinopathy Disease Severity Scale.
* Able to understand and sign an informed consent approved by an IRB/IEC.
* Central subfield macular thickness less than or equal to 320 μm in the study eye prior to cataract surgery.
* Absence of clinically significant macular edema in the study eye as detected by clinical exam.
* Other protocol-defined inclusion criteria may apply.

Exclusion Criteria:

* Signs of vitreomacular traction or epiretinal membrane in the study eye as detected by the reading center or Investigator.
* Current or previous ocular disease other than diabetic retinopathy in the study eye that, in the opinion of the Investigator, would have confounded the assessments of the macula, the retina, or central vision.
* Planned multiple procedures for the study eye during the cataract/IOL implantation surgery (eg, trabeculoplasty, corneal transplant).
* Corneal transplant in study eye.
* Baseline cumulative corneal fluorescein staining score (ie, sum of scores for all 5 corneal regions) for the study eye greater than or equal to 5, or baseline corneal fluorescein staining score in any single region for the study eye greater than or equal to 3.
* Other protocol-defined exclusion criteria may apply.
B: Inclusion Criteria:

* Patients with non-proliferative diabetic retinopathy (mild, moderate or severe) and planned cataract extraction by phacoemulsification.
* Other protocol-defined inclusion criteria may apply.

Exclusion Criteria:

* Central subfiled macular thickness greater than or equal to 250 microns
* CME in either eye.
* Other protocol-defined exclusion criteria may apply.
C: Inclusion Criteria:

* Patients older than 40 years with age-related cataract, and a normal ophthalmologic examination besides senile cataract.

Exclusion Criteria:

* Previous ocular surgery, central endothelial cell count less than 2000 cells/mm2, glaucoma or intraocular pressure greater than 21 mmHg, amblyopia, retinal abnormalities, steroid or immunosuppressive treatment, connective tissue diseases, or an allergy or hypersensitivity to NSAIDs. Enrolled patients who had complicated cataract surgery (eg, posterior capsule rupture, vitreous loss, or an intraocular lens not placed in the capsular bag) were subsequently excluded
D: Inclusion Criteria:

* · Male or female \> 18 years of age scheduled to undergo cataract surgery with surgeon expectation of 20/20 BCVA postoperatively

  * Must be in good general health. Patients with systemic diseases will be enrolled only if there are no ocular manifestations of their disease (ie diabetics with normal retinal exams)
  * Ability to provide informed consent and likely to complete all study visits

Exclusion Criteria:

* · Known contraindication to any study medication or any of their components

  * Uncontrolled systemic disease
  * Required use of ocular medications other than the study medications during the study
  * Abnormal pre-operative OCTs if obtainable
  * Diabetic patients with a history of macular edema or diabetic retinopathy
  * AMD patients with less than a 20/20 surgical outcome expectation, epi-retinal membranes, retinal vein occlusion, or any pre-existing macular disease
