Some netizens consulted: I just entered the university when I did a laser myopia surgery, now almost five years, that is feel very good, vision is also a lot, but then read the university that will, and classmates play games every day, now work is also every day to the computer, so I am myopia again, so I want to do a laser myopia surgery, I don't know if I can do this kind of surgery? How many times can laser myopia surgery be done? Here are the answers for everyone.
The doctor said that although the laser myopia surgery will not rebound, if you do not pay attention to the use of the eyes after the operation, you can still be myopia again, so you must develop a good habit of using the eyes correctly after the operation, so as not to be myopia again.
Generally speaking, myopia can generally only be operated on once, and the second operation is very difficult. This is in terms of traditional myopia surgery, because laser surgery for myopia is corneal refractive surgery, which, as the name suggests, is to surgically change the anterior surface morphology of the cornea to correct refractive errors. Some also call it "subtractive myopia surgery" because this laser surgery is irreversible. Therefore, laser surgery is to strive for one step in place and try to avoid secondary surgery. At the current level of laser surgery, the success rate is very high, and the possibility of postoperative myopia is extremely small.
In addition, there is also an "additive myopia surgery" - icl surgery, which is different from lasers and other surgeries that cut corneal tissue, it does not cut the cornea, and the crystal is implanted into the eye through minimally invasive surgery, without damage to the cornea, and the vision is clearer after correction. In the future, if there is something inappropriate about the implanted crystal, it can be removed or replaced by surgery, which is reversible. From a clinical medical point of view, the procedure can be done more than twice.
The ophthalmologist of Shenzhen Boai Shuguang Hospital reminds that if it is necessary to undergo laser myopia surgery again, it is still necessary to carry out strict preoperative examination to ensure that the conditions of the eyes are suitable for surgery and that the cornea thickness can meet the surgical requirements. However, the specific myopia surgery is more suitable for you, you have to go to a regular and experienced eye hospital, after a comprehensive eye examination, the doctor will choose the best.
