Postoperative Ocular Infection

When dealing with postoperative ocular infection, an infection that occurs after eye surgery such as cataract removal, retinal procedures, or refractive correction. Also known as post‑surgical eye infection, it can involve the cornea, conjunctiva, or deeper structures like the vitreous. Endophthalmitis is the most feared form because it threatens vision within days of the operation. The condition encompasses bacterial, fungal, and occasionally viral agents, each with its own risk profile. Antibiotic prophylaxis reduces the incidence of infection when administered pre‑operatively and post‑operatively, while a strict ocular surgery sterile protocol limits organism entry. In practice, postoperative ocular infection requires early recognition of symptoms—pain, redness, decreased vision, or discharge—so that targeted therapy can be started promptly. Studies show that using intracameral cefuroxime at the end of cataract surgery drops infection rates from roughly 0.1% to 0.02%, illustrating the direct link between prophylactic measures and outcomes. The infection’s severity depends on factors like wound integrity, patient immune status, and the type of intra‑ocular lens implanted, making personalized risk assessment essential.

Key Factors and Practical Steps

Understanding the interplay between endophthalmitis and broader infection control helps surgeons and patients alike. Effective antibiotic prophylaxis not only involves a single drug but may combine topical drops, intracameral injections, and postoperative oral agents, tailored to the procedure’s risk level. A sterile environment during ocular surgery—including proper draping, instrument sterilization, and minimizing operative time—directly influences infection rates. Moreover, patient‑specific measures such as controlling diabetes, avoiding pre‑operative eye rubbing, and adhering to post‑operative drop schedules further lower risk. When infection does occur, rapid microbiological sampling, prompt intravitreal antibiotics, and sometimes vitrectomy are the standard of care, highlighting the importance of early detection.
