Many patients with myopia have undergone lens implantation surgery. So what is lens implantation surgery? Generally speaking, lens implantation surgery refers to ICL implantation, which is implanted in the eye. An artificial refractive medium to correct myopia or hyperopia. Generally speaking, there are only three types of people who are suitable for this kind of surgery. These three types of people are:
The first type: those with high myopia, relatively thin corneal thickness or poor corneal shape. Patients with low myopia;
Category 2: Those who are not suitable or unwilling to accept glasses or contact lenses and have the desire to undergo refractive surgery;
Category 3: exclude glaucoma and uvea inflammation and other eye diseases, diabetes, autoimmune diseases, etc.
ICL implantation has many advantages, such as stable or even improved visual quality after surgery, certain reversibility, wide range of correction, etc. Although this kind of lens implantation has many advantages, it also has very shortcomings. Obviously, generally speaking, this kind of lens implantation surgery has the following major disadvantages:
First, the price of the surgery is very expensive. Generally speaking, the price of ICL crystal is about 35,000, and the price of SMILE, the most expensive laser surgery, is about 20,000. Obviously, it is equivalent to 70% more expensive than laser surgery, which is the number one disadvantage of lens implant surgery.
The second is that there are usually complications after surgery. These complications include the following:
1. Eye infection (called endophthalmitis);
2. Cataracts: In the seven years after surgery, hundreds of One to two patients will suffer from cataracts (older patients with higher myopia are at higher risk);
3. Glaucoma: Lens implantation will cause the release of pigment in the iris, thereby blocking The drainage system of the eye increases intraocular pressure and leads to glaucoma;
4. Retinal detachment (any intraocular surgery increases the risk of retinal detachment from the back of the eye);
5. Acceleration Normal corneal aging may cause it to become cloudy.
In short, although ICL implantation has many advantages, the disadvantages are also very obvious. If you also want to have this type of surgery, you must think about it.
