The participants included 1423 eyes undergoing elective intraocular surgeries (e.g., cataract, keratoplasty, trabeculectomy) or receiving intravitreal injections. The interventions studied were PVI combined with third-generation quinolones (levofloxacin, moxifloxacin, or gatifloxacin) compared with PVI alone. The outcome measure was post-intervention rate of positive conjunctival bacterial cultures prior to ophthalmic procedure.</p><p><strong>Clinical relevance: </strong>Postoperative endophthalmitis is a rare but serious complication of intraocular surgery, potentially leading to significant vision loss. While PVI is widely recognised as an essential prophylactic measure, the role of preoperative topical antibiotics remains debated. Defining the necessity of antibiotic use in routine cataract surgery is important, especially given the concerns about antibiotic resistance and the rising cost of healthcare. The current standard of care varies globally, with PVI commonly used alone in many regions, such as the UK.</p><p><strong>Methods: </strong>Studies were included based on the comparison of preoperative PVI with or without antibiotics in patients undergoing intraocular surgery.

Patients were randomized into two groups: patients laid down for one hour after surgery due to the clinical standard (LD group), patients walked around in the first postoperative hour (W group). No miotic eye drops were applied at the end of operation. A retroilluminated slit lamp picture was taken at the end of the operation (baseline), one hour and one day postoperative. Changes in IOL position were measured by an axis between two episcleral landmarks and the haptics of the IOL. Measurements were performed by an image processing application specified for medical and scientific purpose. If not normally distributed, the paired t-test was used. Otherwise, the Mann-Whitney-U-Test was used if data was not normally distributed.</p><p><strong>Results: </strong>IOL rotation in the first hour was 1.80° ± 1.80° in the LD group and 1.21° ± 2.11° in the W group (p=0.123).
