Cataracts rank first among the blindness-causing eye diseases in the world and are also the first blindness-causing eye disease in China. With the gradual aging of our society, the number of cataract patients will increase. Currently, the only effective cataract treatment is surgery. Cataract surgery has made rapid development in the past half century and has gone through three stages: intracapsular cataract extraction, extracapsular cataract extraction and ultrasound emulsion extraction. In the past, cataract surgery required a large incision (about 12mm), large astigmatism in patients after surgery, long recovery time and unsatisfactory results. The mainstream of modern cataract surgery is ultrasonic emulsification combined with IOL implantation, which is very popular among patients and doctors because of the small surgical incision (about 3.2mm), fast recovery and no significant pain during surgery.
With the progress of the times, microincision cataract surgery was born to meet the higher requirements of patients. Micro-incision cataract surgery refers to surgery with incisions below the standard cataract surgery incision, and currently the clinical incision can be 1.8mm, which is only the size of a pinhole of an embroidery needle. The incision does not require stitches, and the surgery usually takes only 10 minutes, and young patients can go to work the day after surgery. Once this new technology was introduced, it was welcomed by cataract patients. After preliminary clinical practice, it was found that the surgery was safe and painless for patients, with fast postoperative recovery and good visual quality, bringing a boon to the majority of cataract patients and friends.
