Cystoid macular oedema (CMO), fluid accumulation within the layers of the central retina, is one of the most common causes of suboptimal visual acuity following otherwise uncomplicated cataract surgery. Its clinical incidence varies in published literature but is generally estimated between 1–2% in non-diabetic populations, with higher rates in patients with diabetes, uveitis, or epiretinal membrane. ¹
CMO prevention at Blue Fin Vision® is addressed at multiple points in the surgical pathway. Preoperatively, patients are assessed for risk factors including diabetic retinopathy, prior uveitis, vitreoretinal pathology, and previous CMO in the fellow eye. This informs the postoperative pharmacological protocol for each patient.
Postoperatively, all cataract surgery patients at Blue Fin Vision® receive combination topical therapy including both corticosteroid and non-steroidal anti-inflammatory (NSAID) eye drops. The evidence base for NSAID prophylaxis in reducing CMO incidence is robust. ² Current consensus guidelines recommend a treatment duration of four to six weeks for standard-risk patients, with extended courses considered for those with identified risk factors.
Intraoperative technique also contributes to CMO prevention. Minimising surgical inflammation through efficient, low-energy phacoemulsification and meticulous wound construction reduces the prostaglandin cascade that underpins CMO pathogenesis.
At Blue Fin Vision®, the low posterior capsule rupture rate, itself a risk factor for subsequent CMO, reflects a surgical technique that minimises intraoperative complications and the inflammatory sequelae associated with them.
CMO prevention at Blue Fin Vision® is a protocol-driven process, not a passive outcome. Risk stratification, pharmacological prophylaxis, and surgical technique together determine CMO incidence within a practice.
