Effectiveness and Safety of 0.5% Moxifloxacin Hydrochloride Ophthalmic Solution in Perioperative Sterilization in Patients Undergoing Ophthalmic Surgery

Study Overview
=================
Brief Summary
-----------------
This is a non-interventional, uncontrolled, prospective, multicenter, post marketing surveillance study.

Detailed Description
-----------------
The study treatment i.e., 0.5% Moxifloxacin hydrochloride ophthalmic solution will be prescribed as per approved label; the assignment of the patient to the therapy will be decided within the current practice and the medical indication and will clearly be separated from the decision to include the patient in the study. The treatment period for each patient will be maximum 17 days from start of Moxifloxacin treatment. Study visit will be 1 day prior to surgery, day of surgery (Day 0) and 1 (day of surgery / post surgery), 7, and 14 days post-op (Note: Since its non-interventional study, the eligibility confirmation can be 1 or 2 days prior to the surgery depending on investigator's discretion). After the patients sign the informed consent, the patients will be advised to start with Moxifloxacin ophthalmic solutions 2 days prior to the surgery and will be advised to administer it 5 times a day. On the Day 0, day of the surgery, the patient will be instilled 1 drop of Moxifloxacin in the eye which will be operated prior to surgery and 1 drop twice post surgery. From Day 1 post surgery, patient will have 1 drop of Moxifloxacin instilled three times a day up to Day 14 (14 days after surgery). If there are any signs and symptoms of endophthalmitis, then at the investigator's discretion, Gram Stain & Culture assessment of aqueous & vitreous fluid may be performed post surgery on Days 1, 7, and 14.
