Post-operative dry eye disease (DED) may arise due to several factors such as pupillary dilation, antiseptic procedures, intraoperative exposure to light, and suction procedures. 1 In the preoperative examination of cataract patients, nearly 63% showed decreased tear break-up time. 1 The post-operative DED may persist for three months or longer. 1 Also, the perioperative damage to the ocular surface can lead to tear film insufficiency and a series of dry eye symptoms.
The most interesting feature of DED is that it is more prevalent in the elderly and women than in men. 2 In addition, post-operative DED can have an adverse effect on the recovery outcomes and time, thereby impacting the patients’ quality of life. 3
