In Mr A’s cataract surgery eye drop regimen, how many times per day should Tobradex be used in Week 1?

• A. Three times daily
• B. Four times daily
• C. Once daily
• D. Twice daily

Answer: (B)

Postoperative eye drops after cataract surgery are designed to control inflammation and prevent infection during the early healing period. Tobradex combines an antibiotic with a corticosteroid, so keeping drug levels high in the eye for the first week is important. Dosing four times a day maintains consistent therapeutic levels throughout waking hours, providing effective anti-inflammatory action while continuing antibiotic coverage as the eye heals. Doses of three times daily or less would risk gaps in protection during this critical period, and once-daily dosing is typically not sufficient to control both inflammation and infection right after surgery. After the first week, the frequency is often tapered as healing progresses, but in Week 1 four times daily is the standard approach.
