Recently, 87-year-old Master Sun was happy because he not only saw, but also saw very clearly. 5 years ago, Master Sun felt gradually unable to see clearly and had been diagnosed with cataracts at the hospital, but some doctors and relatives around him told him that cataracts must wait until they were ripe, so Master Sun began a long process of waiting, and last year, he finally could not see at all, and went to several hospitals with the help of his family. Last year, he finally couldn’t see at all and went to several hospitals with the help of his family, but they all told him that the cataract was too heavy, the risk of surgery was too great, there were many complications, and he might not be able to see even after the surgery.
In March of this year, Mr. Sun, who could not tolerate the pain of blindness, came to Suzhou City Optometric Hospital and found Vice President Li Guoxing, a cataract specialist. Considering that Mr. Sun’s cataract was a large brown-black hard nucleus cataract, the current mainstream cataract ultrasound emulsification technology was too risky and had many complications. Therefore, Vice President Li Guoxing chose the safe small incision cataract extraction combined with IOL implantation for the patient.
After detailed preoperative examination and exclusion of contraindications to surgery, the patient’s surgery began with surface anesthesia and a 4mm size incision. Mr. Sun said, “I want to tell people around me that cataract must not wait until they can’t see, the waiting process is too painful.
According to Vice President Li Guoxing, the so-called cataract is a part of the human eye equivalent to the lens of a camera, called the “lens”, the lens is transparent under normal circumstances, when the lens is cloudy, the formation of “cataract”, the elderly are common. The normal lens is divided into the cortex and the nucleus. During the formation of cataract, both the cortex and the nucleus will become cloudy, and if the nucleus of the lens becomes severely cloudy, it will gradually turn brown or even brownish black. This type of cataract is more difficult to operate on due to the increased hardness of the nucleus.
The so-called ultrasound emulsification technique is to emulsify the cloudy cataract into a shattered substance through a 2~3mm incision and then implant an artificial lens to restore vision. Therefore, if the nucleus of the lens is very hard, the difficulty of emulsification increases, the emulsification time is prolonged, and the chance of surgical complications such as corneal edema and posterior capsule rupture increases, which affects the recovery of patients after surgery.
With the advancement of technology, cataract surgery is not only fast but also very safe, generally no anesthetic injection is needed, only surface anesthesia drops are needed, the operation time is generally only 5~10 minutes, and the patient can be discharged after 2 hours of postoperative observation, no hospitalization is needed. Pay attention to eye hygiene within 7 days after surgery, and you can usually live and move around normally after 1 week. Therefore, Vice President Li Guoxing suggests that cataract patients can consider surgery when their vision decreases and affects their life, instead of waiting until they can’t see. In addition, Vice President Li Guoxing reminded cataract patients that there is no effective drug treatment for cataract, so pure drug treatment cannot cure cataract, and surgery is the only effective way to treat cataract.
Many cataract patients are also concerned about whether cataracts will recur after surgery. Vice President Li Guoxing said that cataracts will not recur after surgery, and if vision gradually decreases, it is possible that posterior cataract has occurred.
