Treatment of pain and inflammation after Cataract Surgery
Brief summary
This is a Phase 2, multi-center, randomized, parallel-arm, double-masked, placebo-controlled study. One (1) to 2 days prior to their scheduled cataract surgery, each study subject will be randomized (2:1) in to one of two treatment groups: N-PPDS or p-PPDS, which are inserted in the lower punctum of the subject's scheduled surgical eye. All plugs will remain in the study subject's lower punctum for a period of 2 weeks following cataract surgery.
Detailed description
This is a Phase 2, multi-center, randomized, parallel-arm, double-masked, placebo-controlled study. One (1) to 2 days prior to their scheduled cataract surgery, each study subject will be randomized (2:1) in to one of two treatment groups: Group A: A total of 50 study subjects (50 eyes) will have an N-PPDS inserted in the lower punctum of their scheduled surgical eye. Group B: A total of 25 study subjects (25 eyes) will have a p-PPDS inserted in the lower punctum of their scheduled surgical eye. All plugs will remain in the study subject's lower punctum for a period of 2 weeks following cataract surgery.
Interventions
A punctal plug delivery system (PPDS) is being developed as a device that can deliver a sustained release of a drug to a specific eye. The PPDS is made up of a medical grade silicone punctal plug which holds an insert (core) that contains nepafenac, a nonsteroidal anti-inflammatory drug.

Eligibility
Inclusion criteria
1. A male or female subject in good general health, ≥ 22 years of age at the time of the screening visit 2. A subject with a cataract for which routine phacoemulsification extraction and implantation of an intraocular lens has been planned 3. A subject has a lower puncta that can be dilated to 1.0 mm in their scheduled surgical eye
Exclusion criteria
1. A subject with a history of complications, adverse events, trauma or disease in the nasolacrimal area, whether or not it was due to punctal plug wear, including but not limited to dacryocystitis, inflammation or canaliculitis in either eye 2. A subject with structural lid abnormalities (e.g., ectropion, entropion) in their schedule surgical eye 3. A subject with a puncta \>0.9 mm prior to dilation in their scheduled surgical eye 4. A subject with any signs of intraocular inflammation (cells/flare) in either eye at the screening visit 5. A subject with a known sensitivity to nepafenac or any inactive ingredient of the punctum plug, silicone, fluorescein, topical anesthetic, or any other products required for study procedures or cataract surgery 6. A subject with a history of chronic/recurrent inflammatory eye disease (e.g., scleritis, uveitis, herpes keratitis) in either eye
