New Advances in Clinical Research on Dry Eye after Ultrasound Phacoemulsification Surgery for Type 2 Diabetic Cataracts

With the increasing prevalence of phacoemulsification surgery in our country, particularly refractive cataract surgery, patients have higher expectations for postoperative visual quality. However, symptoms such as redness, dryness, foreign body sensation, and blurred vision due to postoperative dry eye can adversely affect the visual quality and satisfaction of surgical patients. This is especially true for patients with type 2 diabetic cataracts, who may experience exacerbated dry eye symptoms postoperatively, which, in severe cases, can lead to complications such as corneal epithelial defects and corneal ulcers, resulting in vision impairment and becoming a cause of medical disputes. Consequently, postoperative dry eye following cataract surgery has garnered increasing attention. Strengthening the diagnosis and treatment of dry eye in diabetic patients during the perioperative period is a crucial means to enhance surgical safety and effectiveness. This article will provide a brief overview of the current status, pathogenesis, manifestations, and recent advancements in treatment methods for postoperative dry eye in diabetic cataract patients in China.
