Same-day bilateral cataract surgery shows strong safety profile — but it's not for everyone

Operating on both eyes in one visit is safe — under the right conditions. A multicenter retrospective study of 797 patients (1,594 eyes) found that same-day bilateral cataract surgery, performed without IV sedation or an anesthesiologist, demonstrated a favorable safety profile comparable to traditional single-eye surgery. Presented at the AAO 2026 Annual Meeting, the findings showed zero cases of endophthalmitis or toxic anterior segment syndrome, and an anterior vitrectomy rate of just 0.25% — consistent with prior studies.

But it's not a one-size-fits-all solution. Lead researcher Dr. Christopher Yo emphasized that ideal candidates are calm, healthy patients with straightforward cataracts and no risk factors for corneal or macular edema, uveitis, or cardiac complications. Surgeons with high complication rates should not attempt it, and if an unexpected anterior vitrectomy is needed on the first eye, the second eye should not be operated on the same day.

Key Takeaways

• Use separate instruments, gloves, and gown for each eye — treat each as an independent surgery
• Avoid in patients with posterior polar cataracts, cardiac devices, or MI risk
• Requires dedicated, experienced ophthalmic staff — less ideal in multispecialty ASC settings
• Medicare reimburses the second eye at only 50%, creating financial disincentives in fee-for-service settings
• Best suited for capitated systems (e.g., Kaiser Permanente) or VA settings with long wait times

Why it matters: With over 3.5–4 million cataract surgeries performed annually in the US, same-day bilateral surgery could save patients time and reduce costs — potentially up to $896 million in anesthesia fees per year. But broader adoption hinges on patient selection, surgeon expertise, and reimbursement reform.
