Cataract and diabetes: review of the literature

Cataracts can cause visual impairment in diabetic patients. Diabetes mellitus affects different parts of the eye and causes many complications and problems before, during, and after intraocular surgeries. In this review, we will discuss the effects of diabetes on different aspects of cataract surgery and review the current management of diabetic cataracts. Careful preoperative examination of the patient's ocular surface, cornea, iris, and posterior segment, as well as the use of advanced phacoemulsification techniques, new intraocular lenses and the appropriate use of auxiliary medications such as nonsteroidal anti-inflammatory drugs and anti-vascular endothelial growth factors have improved the outcomes of cataract surgery in diabetic patients.
