Myopia surgery is also known as ICL intraocular lens implantation, which is a technique to achieve refractive correction through the implantation of an IOL. 1. Small incision: The incision for the surgery is usually small and does not require surgical sutures; 2. Fast results: Patients can usually feel the effect of vision correction immediately after the surgery; 3. Patients who do not want to continue to carry, or whose vision has changed and are not suitable to continue to carry the crystal, can remove or replace the crystal at any time, and then wear contact lenses or frame glasses again for improvement; 5. Wide range of correction: In addition to myopia, for patients with low astigmatism, farsightedness, etc., can also be corrected by means of crystal implantation. 2. Cons 1. Infection: There is a possibility of infection after surgery, and if serious infection occurs, it may affect vision; 2. Axis rotation: Not suitable for people with high astigmatism, which may lead to rotation of the axis, thus affecting the comfort and clarity of the wearing process; 3. Economy: The price of crystal implantation for myopia surgery is relatively expensive; 4. Dislocation: Some patients may experience dislocation or semi-dislocation after surgery. The dislocation or semi-dislocation of the lens may seriously affect the improvement of vision after IOL surgery; 5. Complications: It may affect the metabolism of the lens and cause cataract, and the increase of intraocular pressure may lead to glaucoma, etc., but it is generally controllable. For patients with myopia correction needs, in addition to crystal implantation myopia surgery, they can also consider correcting it by wearing glasses or performing keratoconus surgery. You should also be careful not to overuse your eyes, avoid long hours of overtime and late nights, and relax your eyes with eye massage when you have free time.
