[Cataract surgery in diabetics]

Patients with diabetes mellitus have an increased risk of developing cataract and of postoperative complications. Postoperative cystoid macular edema is more common and prolonged in patients with diabetes. Furthermore, it has been clearly shown that cataract surgery favors the progression of diabetic retinopathy. For all these reasons, when cataract surgery is indicated for a diabetic patient, it is essential to thoroughly examine the patient's retinopathy before surgery, as this conditions the postoperative functional visual prognosis.
