Antibiotic prophylaxis for cataract surgery - Practice patterns amongst Indian Ophthalmologists

PURPOSE: To assess the current trends in use of perioperative antibiotic prophylaxis, especially intracameral antibiotics (ICAB), for cataract surgery in India. METHODS: This was an E-survey using a previously validated questionnaire carried out by the All India Ophthalmological Society (AIOS) in August 2022. An E-mail invitation to complete an online 40-point survey was sent to all members of the AIOS using a digital E-mail service (Survey Monkey) and social media platforms. RESULTS: Out of 1804 total respondents, 58% (n = 1022) reported using routine ICAB prophylaxis. Of those using ICAB, 89% (n = 909) reported using it for all cases, whereas the rest used it for specific indications such as post-PC rent (n = 43), one eyed patient (n = 19), and high-risk cases (n = 50). Commercially available moxifloxacin was by far the commonest agent used for ICAB (n = 686, 67%). Eighty respondents (8%) reported noticing occasional toxic reactions and nontoxic corneal edema (n = 64, 6%) with ICAB. Surgeons with >10 years’ experience especially practicing in medical colleges used fewer ICAB (OR = 0.52, 95%CI = 0.38 – 0.72, P < 0,001) compared to younger surgeons (<5-year experience) in solo clinics. The commonest reason for nonadoption of IC antibiotics was “unconvinced of the need to use it in my setting” (n = 296, 52% of those who answered this question). CONCLUSION: IC antibiotic prophylaxis for cataract surgery has significantly increased in India from 40% in 2017 to 58% in 2022. Commercially available moxifloxacin was preferred by the majority users. Intraocular inflammation may occur occasionally and needs safer formulations to avoid this.
