Recently, 68-year-old Ms. Fang finally solved her cataract problem that had been bothering her for years. It turns out that Ms. Fang had a serious loss of corneal endothelial cells due to a previous glaucoma attack, and conventional cataract surgery was risky. The femtosecond laser cataract surgery system introduced by Yinzhou Eye Hospital 2 years ago can remove the nucleus mass with lower super-emulsion energy and protect the intraocular cell tissue, which is suitable for special cases like Ms. Chen Fang. After the surgery, Ms. Fang’s vision recovered from 0.05 to 0.6. According to the introduction, “blade-free, precise and safe” are the characteristics of femtosecond laser cataract surgery, which also makes some difficult cataract surgery possible.
The woman’s glaucoma was controlled after treatment, but as she grew older, her vision became blurred. After a checkup at a local hospital, the doctor told her that the reason for the blurred vision was cataracts in both eyes, but due to the glaucoma attack, she had a serious loss of corneal endothelial cells and could not undergo conventional cataract surgery. Ms. Fang was very disappointed, could she only live in a blurred world for the rest of her life?
Cataract surgery is performed under the cornea, and the more severe the cataract is, the more energy is needed for the surgery. Patients with poor corneal endothelial cells will suffer from corneal edema and cloudiness due to the loss of endothelial cells, and in severe cases, corneal transplantation may be required. Ms. Fang’s cataract was already severe and her corneal endothelial cells were in poor condition. If she wanted to undergo surgery, she could use a femtosecond laser cataract surgery system. After consideration, Ms. Fang finally chose the femtosecond laser cataract surgery. The surgery went smoothly and Mr. Chen’s vision was restored to 0.6 after the surgery. “Knifeless” solution to three problems for better visual results Traditional cataract surgery incisions are operated by human beings, and there are more or less errors or even mistakes in accuracy, which affect the final result.
Femtosecond laser solves three major problems in cataract surgery: 1. More precise centering of the tearing capsule, different capsule openings are made according to the needs of different patients and different IOLs, making the IOL more stable in the eye.
2.Breaking the nucleus of the lens, setting the size of the broken nucleus according to the different degrees of cataract, avoiding the surgeon to operate too much in the eye, thus being able to remove the nucleus block with lower ultra-emulsion energy and protect the cellular tissue inside the eye.
3. The laser precisely makes the surgical incision, realizing “knifeless” surgery and avoiding surgeon’s operation error.
With femtosecond laser surgery system, the surgeon can perform visualization surgery with video image guidance, replacing most of the manual and unstable operations in cataract surgery with precise computerized operations, thus improving the safety and accuracy of surgery and obtaining better postoperative visual quality.
Some special cataracts can also be completed Femtosecond laser cataract surgery is suitable for most cataract patients, especially for those patients with higher vision requirements, such as those who need astigmatism correction, and those who need to see near and far at the same time after surgery to get rid of the need for presbyopic glasses. This is because these patients need more precise surgical design and operation. In addition, for some special cataracts, such as post-glaucoma complication cataract, traumatic cataract and lens dislocation, femtosecond laser technology has very obvious advantages to safely complete the surgery with less damage.
Nowadays, cataract patients no longer have to wait until they are completely blind to have the surgery, but can have the surgery at the right time according to their needs. If they wait until the cataract is fully mature before surgery, on the one hand, it will seriously affect the patient’s life due to visual impairment; on the other hand, an overly mature cataract will also make the surgery itself difficult and affect the post-operative vision recovery.
