"I finally took off my glasses. Now my vision is very clear and my life is much more convenient." Recently, 69-year-old Ms. Ren visited Aier Eye Hospital Underwent cataract surgery .
It is reported that Ms. Ren has been suffering from blurred vision due to cataracts, astigmatism and other problems. Recently, she underwent a trifocal intraocular lens implantation surgery, which solved this problem at the same time.
It is understood that this surgery can simultaneously solve problems such as cataracts, presbyopia , myopia, hyperopia, astigmatism, etc., and can achieve clear vision of "far, middle and near".
Over 40% of cataract patients in my country are accompanied by corneal astigmatism
According to statistics, about 80% of people over the age of 60 in my country are troubled by cataracts. As my country's population ages, the compound growth rate of cataract patients in my country will reach 13.6% from 2020 to 2025.
Professor Zhang Jinsong, member of the Standing Committee of the Chinese Medical Doctor Association’s Ophthalmologist Branch, said, “The aging of human organs is the main cause of cataracts, but now the age of onset of cataracts is getting younger and younger. Now some people in their 40s have already suffered from cataracts.”
"Surgery is the only way to treat cataracts. Failure to perform surgical treatment will eventually lead to blindness, which will seriously affect normal work and life." Professor Zhang Jinsong said, "Currently, cataract surgery is constantly being iterated, especially with the advent of femtosecond cataract surgery. At the same time, Patients can choose to implant a refractive intraocular lens to achieve full vision at distance, intermediate and near after surgery.”
According to relevant surveys, 41.8% of cataract patients have corneal astigmatism greater than 100 degrees. Based on the Chinese expert consensus on the clinical application of multifocal intraocular lens (2019), it is pointed out that when cataract patients choose to undergo multifocal intraocular lens implantation surgery, if the astigmatism is greater than 100 degrees, the problem must be corrected at the same time. Previously, multifocal intraocular lenses with astigmatism correction function could only achieve near and distance vision, but could not solve the problem of astigmatism.
Distance, intermediate and near vision problems are solved at the same time
The astigmatic trifocal intraocular lens used in Ms. Ren’s surgery this time has the function of astigmatism correction, which can correct 100- 300 degree astigmatism range. At the same time, while ensuring the needs of near and far vision, the mid-distance (60cm) vision effect is optimized, which can help cataract patients solve the problem of distance vision (such as walking, traveling), and sightseeing (such as eating, watching computers) , doing housework) and problems such as near vision (such as reading, reading newspapers, looking at mobile phones, etc.).
Experts also said that the lens can also filter harmful ultraviolet light and blue light , protect the fundus, effectively reduce the incidence of related complications , and allow more cataract patients to obtain long-lasting and stable clear and full vision after surgery.
After removing the glasses, the preoperative visual acuity improved from 0.4 to over 0.8.
Ms. Ren suffered from cataracts, her preoperative visual acuity was only 0.4, her eyes had astigmatism of 250 degrees, and her corneal astigmatism was 125 degrees. "I have had blurred vision in my right eye for two years. Sometimes when the light is dim at night, I can't even see the stairs clearly, which is quite dangerous." She said she wanted to improve her vision.
"Because the patient has corneal astigmatism, the existing trifocal intraocular lens cannot correct the degree of astigmatism. If you want to completely lose your lens after surgery, you need to choose an intraocular lens that can solve the astigmatism problem at the same time." Based on the patient's needs, we conducted a detailed and comprehensive After the preoperative examination, Professor Zhang Jinsong led the cataract diagnosis and treatment team of the hospital to tailor a personalized surgical plan for him, and decided to use a femtosecond laser cataract surgery system, a digital navigation system, a 3D visual surgery platform and a master-controlled fluid flow stabilization phacoemulsification multiplex The technology is paired with the latest astigmatism-correcting natural vision trifocal lens, which not only solves cataracts, but also solves many problems such as myopia, hyperopia, presbyopia, and astigmatism.
The surgery went smoothly. On the first day after the operation, Ms. Ren's vision improved from the original 0.4 to 1.0 for distance vision, 1.0 for intermediate vision, and 0.8 for near vision. “The operation lasted 10 minutes and was completely painless.On the first day after the operation, I could see very clearly, whether it was the mobile phone screen in front of me or the scenery in the distance. "Ms. Ren said excitedly. (For more news, please pay attention to Yangcheng Pai pai.ycwb.com)
