# Second-Eye Surgery After Previous CMO: How We Plan and Protect the Macula

Having CMO after first-eye cataract surgery raises understandable anxiety about second-eye surgery. The key is to treat the second eye as high-risk and plan accordingly.

Pre-operatively we obtain detailed macular OCT, document any residual changes and review the course of CMO in the first eye. Intra-operatively we minimise inflammation and vitreous disturbance.

Post-operatively we use extended steroid–NSAID prophylaxis, often beyond six weeks, and schedule earlier OCT checks.¹

Our audited series includes a patient who developed CMO after first-eye surgery elsewhere; in the second eye operated at Blue Fin Vision®, oedema appeared only after extended drops were stopped and resolved when therapy resumed. This reinforces how tightly macular stability is linked to prostaglandin suppression in susceptible eyes.²
