Perioperative nuances of cataract surgery in ocular surface disorders.

Ocular surface disorders (OSDs) constitute a varied spectrum of conditions that could be associated with dryness, compromised limbal status, varying grades of forniceal obliteration, corneal scars, and a possible underlying immune etiology. These associations adversely impact surgical outcomes in the eye. One of the treatable causes of decreased vision in these eyes is cataracts which could be secondary to the disease, its treatment, or age-related. The compromised ocular surface status can interfere with decision-making regarding the technique of cataract surgery, preoperative biometry for intraocular lens (IOL) power calculation, and intraoperative visibility, increasing the possibility of complications and compromising the final visual outcome. The postoperative course can be affected by complications, including melt and infection. Stabilization of the ocular surface by medical or surgical means, and appropriate management of underlying immune etiology, if any, helps improve and maintain a healthy ocular surface, optimizing cataract outcomes. With the help of pre, intra, and postoperative tools and means, such as punctal occlusion, ocular surface reconstruction, systemic immunosuppression, illuminators, capsule staining dyes, optical iridectomy, prosthetic replacement of the ocular surface ecosystem (PROSE) lenses, and others, the visual outcome post-cataract surgery in these eyes can be maximized. This article highlights the nuances of performing cataract surgery in various OSDs and the need to have a comprehensive stepwise approach is emphasized.
