Antibiotic prophylaxis in cataract surgery - An evidence-based approach

Area of Science:

• Ophthalmology
• Infectious Disease Prevention
• Surgical Prophylaxis

Background:

• Endophthalmitis prophylaxis protocols in cataract surgery are debated.
• Intracameral (IC) antibiotic prophylaxis is a key area of focus.
• Recent evidence highlights the impact of various prophylactic strategies.

Purpose of the Study:

• To summarize recent evidence-based studies on endophthalmitis prophylaxis.
• To emphasize the role and efficacy of intracameral antibiotic prophylaxis.
• To discuss safety, adoption, and emerging trends in antibiotic prophylaxis.

Main Methods:

• Review of large, international clinical studies on antibiotic prophylaxis.
• Analysis of efficacy data for intracameral cefuroxime, vancomycin, and moxifloxacin.
• Evaluation of evidence for eyes with posterior capsule tear.

Main Results:

• Majority of studies report significant reduction in endophthalmitis rates with IC antibiotic prophylaxis.
• IC moxifloxacin demonstrates convincing efficacy.
• IC antibiotics show significant reduction in endophthalmitis in high-risk eyes (posterior capsule tear).

Conclusions:

• Intracameral antibiotic prophylaxis is effective in reducing endophthalmitis rates.
• Moxifloxacin is a promising alternative to vancomycin due to safety concerns.
• Increased adoption of IC antibiotic prophylaxis is expected with approved formulations.
