We read with great interest the recent article by Suto et al1 about perioperative glycemic control and progression of diabetic retinopathy and maculopathy in patients with type 2 diabetes mellitus (DM) undergoing unilateral phacoemulsification. They described an interventional prospective case-control study looking at the worsening of the retinopathy level and the worsening maculopathy after cataract extraction in different trends of perioperative glycemic control, and they compared the operated-on eye with the fellow unoperated-on phakic eye with regard to retinopathy and maculopathy progression.
