Cataract is a common eye disease in the elderly, and with the advent of an aging society, there are more and more cataract patients. However, there are misconceptions about the best time for cataract treatment, and many patients have delayed the most ideal treatment time.
Auntie Kong, who has been suffering from cataract in her left eye for more than 2 years, has not been to the hospital, and her daughter urged her to come to the hospital for surgery, but she always excused herself, saying that she was not yet familiar with it. In the past, due to imperfect surgical techniques and equipment, cataracts could not be operated until they were “mature”, and people knew that they could not do it unless they were mature. With the development of microscopic technology in ophthalmology, cataract surgery technology is very mature, and the cataract can be crushed and sucked out by advanced ultrasound emulsification machine, so as long as the cataract affects the patient’s normal work and life, and the visual acuity drops below 0.5, surgery can be performed, and there is no need to live in a long-term low vision state.
Doctors advise patients to consider cataract removal surgery whenever they feel that their vision is getting worse and affecting their daily life. If you miss the best time for treatment and wait until the cataract is too “mature”, it may lead to serious consequences. First, it is easy to induce secondary glaucoma, causing irreversible vision loss, which is more complicated and difficult to treat, and the return of vision after surgery is often unsatisfactory; second, the release of lens material into the eye induces an allergic reaction, leading to allergic uveitis of the lens cortex, which not only affects the treatment of the affected eye, but also may affect the other good eye. Some elderly people even have to remove their eyes because of long-term eye pain, which is unbearable and leaves lifelong regrets.
At present, the only way to completely cure cataract is surgery. With the development of ophthalmic microscopic technology and IOL materials, cataract surgery has entered the era of refractive surgery from the traditional era of restorative surgery.
The principle of surgery is to remove the cloudy lens and implant an artificial lens to replace the role of the original lens convex lens. The current refractive cataract surgery incision has been shortened from 8-10mm to 2-3mm without sutures, painless, only 5-10 minutes, fast recovery, and much safer surgery, and there are more choices of implanted IOLs: multifocal IOLs, astigmatism correction IOLs, aspheric IOLs, and adjustable IOLs to meet the needs of different people. For the needs of the city, is to obtain good functional vision after surgery.
