The goal of this clinical study is to determine if antibiotic eye drops are needed after retinal surgery to prevent infection. Currently, patients are prescribed antibiotic eye drops to use for several weeks after they undergo retina surgery. The main question that we are trying to answer is:

- Are postoperative eye drops necessary to prevent eye infections after retina surgery? Patients will still receive steroid drops after their surgery to control inflammation. Additionally, patients will have regular follow up with their eye surgeon to monitor for the signs and symptoms of eye infection.
