With the acceleration of the aging process of the population, cataract and presbyopia have become a common problem for many middle-aged and elderly friends. What is a cataract?Presbyopia?What should I do if I have these eye diseases?What are the precautions for the daily use of eyes by middle-aged and elderly friends?......
Don't worry, in response to the concerns of middle-aged and elderly friends, Professor Zeng Liuzhi, chief physician of the Department of Ophthalmology of Chengdu First People's Hospital, gave an authoritative answer, let us find out together.
With age, there are some changes in the function, tissues and organs of the human body. Zeng Liuzhi introduced that people over 40 years old, the adjustment function of the eyes began to change, mainly the elasticity of the lens changed, and the elasticity became worse, "There are also cloudy lenses, these changes will cause us to see things blurred, especially when we see closely, there will be unclear, there is glare, this phenomenon is called cataract." ”
Technological innovations: Refractive cataract surgery and functional intraocular lenses continue to advance
The development of refractive cataract surgery, on the one hand, is more mature and stable in removing the cloudy lens (cataract) and implanting various types of functional intraocular lenses to improve vision, while solving the problems of myopia, astigmatism and presbyopia, that is, a type of surgery to solve many of your eye problems.
What should I do if I have cataracts and presbyopia?Zeng Liuzhi said that the most commonly used method for many elderly people is to wear reading glasses, but wearing reading glasses may bring some inconvenience to work and Xi, "Another solution is surgery**, replacing the lens with a functional intraocular lens with reduced self-adjustment function, so as to achieve far, medium and near vision can be seen clearly." ”
The newer is the wavefront remodeling continuous visual range (EDOF) intraocular lens, which is a new type of intraocular lens that can provide far, intermediate, and near continuous visual range with little visual interference, similar to monofocal intraocular lenses.
I started with glasses to correct it, but due to the aggravation of cataracts, my vision was only 05. It caused a lot of inconvenience to daily life and work, and later I decided to have surgery. "Mr. Guo was originally a surgeon, and his eyesight gradually deteriorated due to long-term work, and although he could see more clearly after wearing glasses, he always felt that it was not very convenient. "In addition, I learned that the cataract technology is now relatively mature, so I went to Director Zeng Liuzhi to perform cataract phacoemulsification combined with wavefront remodeling EDOF intraocular lens implantation surgery on me, and the distance vision of both eyes was 1 month after surgery0, middle visual acuity 08. Near visual acuity 08. The effect is very good, now the smaller words can be seen clearly, and it is no problem to drive at night. ”
If surgery is chosen, is there an age limit?Zeng Liuzhi said that if the self-lens aging occurs at a relatively young age, but the crystal is still transparent, it is not recommended to implant an intraocular lens, and vision protection and correction can be carried out through healthy eyes, correct wearing of glasses, etc., "But if the self-lens has been cloudy, no matter whether you are young or old, you can consider intraocular lenses." ”
In addition, for the healthy eyes of middle-aged and elderly friends, Zeng Liuzhi put forward two suggestions, one is that although life, work, and study Xi are inseparable from electronic products, but look at mobile phones, computers, and TV, you still need to pay attention to the time, not too long, and control it appropriately. Second, with the growth of age, the structure of the eyeball will undergo some changes, if the middle-aged and elderly friends watch TV at night and turn off the lights, it is easy to cause intraocular pressure to rise, inducing glaucoma. Therefore, it is recommended that middle-aged and elderly friends turn on the lights when watching TV at night and do not stay in the dark room for too long.
