In addition to no time, want to stay at home
It may also be difficult to see
Today is Double Ninth Festival
Myopia, presbyopia, cataracts…
Eye health is a nuisance for many older adults
Among them, cataracts have the greatest impact
Many elderly people have always been afraid of surgery
Ophthalmology experts from the First Affiliated Hospital of Zhejiang University School of Medicine said
Modern medical technology has advanced to the point
One operation can solve many problems
Today, let’s talk about it
High myopia meets cataract
Auntie, 53, is “blind”
Hangzhou Aunt Liu (pseudonym) is 53 years old this year. She has a high degree of myopia of more than 900 degrees in both eyes and is retired at home. She wears a pair of thick frame glasses for a long time, and her daily life is basically difficult. Affected, but since the second half of last year, she felt that things became blurred. “It always feels like a piece of white gauze is covering my eyes, and it’s foggy.” She thought it was because her myopia had deepened, but she was told that she had cataracts during an examination at a hospital near her home.
“I was originally short-sighted, and I couldn’t see far away. Now I have cataracts. Our local doctor suggested that I go to Hangzhou Grand Hospital for this operation.” Aunt Liu said that due to the situation at the time It’s not very serious, and in addition to the idea that cataracts need to be retired and operated on, this matter has been delayed.
Until recently, Aunt Liu felt that the “fog” in front of her eyes was heavier, like a blackout curtain blocking her eyes. Even with glasses, she could not see the road clearly. It’s like being “blind”. For this reason, she stays at home almost every day, and only goes downstairs for a walk accompanied by her daughter at night.
Retirement is over before it even begins. Unwilling, Aunt Liu was determined to change the status quo, so she came to the Ophthalmology Department of the First Hospital of Zhejiang University for treatment.
It’s fine to see far or near
Multifocal crystals solve troubles
“The examination revealed that she was highly short-sighted in both eyes, and both had moderate-to-severe mixed cataracts.” Lou Dinghua, chief physician, head of the cataract professional group of the Department of Ophthalmology, Zhejiang University First Hospital, introduced that the lens is an important part of the eyeball. Structure, under normal circumstances, the lens is clear and transparent, but under the action of age, trauma and other factors, the degeneration of the lens becomes cloudy and forms a cataract, which affects vision. Further analysis of visual function showed that Aunt Liu’s visual quality was extremely poor and she had to undergo surgery.
“But doctor, I am short-sighted and cataract. Will the operation be very troublesome. Can these problems be solved at one time?”
Facing Aunt Liu’s doubts, Chief Physician Lou Dinghua said with relief that the current cataract surgery can not only solve two problems at the same time, but also can solve the problem of presbyopia by inserting a multifocal intraocular lens. and many other issues.
Chief Physician Lou Dinghua further explained that under normal circumstances, our eyes are like a high-definition camera, which can automatically adjust the focus and see things in the distance and near things clearly. However, many senile cataract patients often have various problems such as presbyopia or myopia. The traditional monofocal lens does not have an adjustment function. Patients can only choose to see near or far, and often need to wear a pair of myopia or reading glasses after surgery. . The multifocal intraocular lens breaks through this limitation, realizing that objects in multiple positions can focus on the retina, satisfying near, intermediate and far vision, bringing good news to cataract patients.
Femtosecond laser can also treat cataracts
Eye regains ‘young age’ after surgery
A few days ago, Chief Physician Lou Dinghua performed femtosecond laser-assisted cataract surgery and multifocal intraocular lens implantation for her.
If a cataract is compared to a grape, the grape skin is the capsular bag of the lens, the grape flesh is the lens cortex, and the grape nucleus is the lens nucleus. During traditional phacoemulsification, the doctor will open a small opening (tear the grape skin) Capsule), the inner lens cortex and lens nucleus are “cleaved” (cleaved nucleus), “crushed” (phacoemulsification), and then suctioned out, and then the intraocular lens is implanted.
In the past, the “capsulorhexis” was done manually by doctors, which put forward extremely high requirements on the stability and accuracy of the doctor’s operation. With femtosecond laser technology in the treatment of myopia Mature application in , in recent years, it has also been used in cataract treatment. The femtosecond laser replaces the traditional scalpel. With the assistance of the computer imaging system, the key steps such as incision, capsulorhexis, and nuclear splitting that are manually completed in traditional surgery are completed, avoiding manual operation errors, and truly realizing the knife-free cataract surgery. , to achieve precise, minimally invasive, safe and fast surgical results.
Currently, after surgery and multifocal intraocular lens implantation, Aunt Liu has achieved 1.0 visual acuity in both eyes after surgery.
The world’s first cause of blindness
Seek medical attention if found
“Cataract ranks first among the causes of blindness due to eye diseases, and it is the first cause of blindness in the world.” Chief physician Lou Dinghua introduced that most cataracts start at the age of 40, and the incidence increases with the age of 40. It increases with age. The prevalence of cataracts in people aged 60 is 30%, and when they are 70 years old, it increases to 50%, and patients with high myopia will develop cataracts earlier. Therefore, it is recommended that people over 50 years old should take Check your eye health.
Once a cataract is diagnosed, it should go to a professional medical institution for treatment. “The older the cataract, the better” is a misunderstanding. Delaying treatment will not only affect life but also affect the treatment effect.
For cataract patients diagnosed as requiring surgical treatment, multifocal intraocular lens placement can be selected under the evaluation of the doctor. Generally speaking, it is suitable for the following people:
01
A cataract patient with no obvious corneal scar, irregular astigmatism, no lens dislocation, suspensory ligament laxity, and no obvious fundus lesions.
02
Patients who are eligible for a multifocal IOL after a complete eye exam.
03
Abundant life or work activity needs (distance, intermediate, and near vision needs).
