Cataract is a common disease in the elderly, but many elderly people have been informed of the disease but do not want to operate, “some patients because of the fear of surgery, bought some drugs advertised on the market, according to the instructions to use a few courses of treatment, but not effective, but more difficult to see things, and finally had to come to the hospital to do surgery, such examples are very common in the clinic. ” In the past, due to the limitation of medical technology, cataracts had to wait until they were completely “mature” and the affected eyes could not see before surgery, and patients had to endure the trouble and pain of low vision for a long time. Nowadays, with the application and development of cataract ultrasonic emulsion aspiration combined with IOL implantation, the safety and effectiveness of cataract surgery have been greatly improved, and patients do not have to wait until they are completely blind before having surgery.
Early surgery does not increase the risk of surgery for experienced surgeons. For different patients, how early or late they receive surgery can result in different outcomes. In developed countries patients with corrected visual acuity of 0.6 or less must undergo surgery. Otherwise, they cannot hold a driver’s license. In China, it is generally considered that patients with vision less than 0.4 to 0.5 with proper glasses can be considered for surgery. Currently, the main surgical procedure mostly uses ultrasound emulsification, which has a small surgical incision, no sutures, fast post-operative recovery, little astigmatism and few complications.
Cataract surgery is not complicated, and the whole procedure takes only ten to twenty minutes, without pain or fear. We have successfully operated on a 100-year-old man. After cataract removal, many elderly people feel that their quality of life has been greatly improved, and the blurred bus signs, people walking across the street, and the scenery of outings have become clearer and more relaxing. Therefore, the elderly should first overcome their psychological fears, and secondly, if they have diabetes, hypertension and other diseases, they can come to surgery if their blood pressure and blood sugar are controlled normally first.
