In addition to restoring vision, cataract surgery has these benefits

Editor's note: Cataract is the first eye disease causing blindness in the world, and about 46% of the world's blind people are blinded by cataract. The current mainstay of cataract treatment is surgical removal of the cataract—removing the cloudy lens and inserting an intraocular lens to restore clear vision to the patient. This is also the most obvious benefit for patients. But did you know there are other benefits of cataract surgery that are not related to the eye? Professor John Hovanesian, an ophthalmologist and a member of the academy, an expert in cataract and corneal surgery, pointed out that with the development of new technologies, cataract surgery can not only improve vision, but also preserve more capabilities and help patients enjoy a better quality of life. Benefit #1: Life becomes more interesting While there are many things in life that people have no control over, people with cataracts have plenty of say in how their vision can be changed. Before surgery, cataract patients will discuss with their ophthalmologist which intraocular lens to choose. In the end, the doctor will comprehensively evaluate the patient's vision, hobbies, occupation, budget and other factors, select the most suitable intraocular lens for the patient, and correct hyperopia, myopia or astigmatism while removing the cataract. This means that many patients can reduce or even stop relying on glasses when reading, working, watching TV, and driving; many also find that they can resume their previous hobbies. Professor Hovanesian added that under normal circumstances, cataract surgery can improve patients' vision and quality of life, and things that are inconvenient to do before surgery, such as sewing and reading, can be easily done after surgery; ability". One of Professor Hovanesian's patients had always dreamed of diving, but was too short-sighted to try it. After cataract surgery, the patient achieved good distance vision without wearing eyes, finally realizing his years-long dream. Benefit 2: Preventing falls and injuries Falls are the leading cause of injury and death in the elderly, and the long road to recovery after a fall can lead to social isolation and even depression in the elderly. About one-third of falls occur among older adults who wear bifocal or multifocal glasses. These glasses reduce contrast sensitivity and depth perception, which can cause people to fall on the side of the road or on steps. Intraocular lenses reduce the need for glasses by correcting near vision, intermediate vision or distance vision, and some patients do not need glasses after surgery. In fact, studies have shown that cataract surgery can reduce the risk of falls in older adults. Benefit Three: Prevention of Dementia The relationship between vision loss and dementia has been the focus of research. A new study draws the convincing fact that removal of cataracts reduces the risk of dementia. The study followed more than 3,000 older adults diagnosed with glaucoma or cataracts for 24 years. Balancing factors such as education level, ethnicity, health history and access to health care, the results showed that people who had cataract surgery were about 30 percent less likely to develop dementia than other groups. Professor Hovanesian explained that cataract surgery prompts people to use more vision to blend into their surroundings, and when people have better vision, it stimulates certain parts of the brain that help keep the brain at normal levels. All of these benefits suggest that a comprehensive eye exam at age 40 is necessary. Regular eye exams can detect and treat cataracts and other vision-threatening eye problems early. Ophthalmologists can better help the elderly population maintain and improve their quality of life.
