The first category: patients with high myopia, relatively thin corneal thickness or poor corneal morphology;
The second category: people who are not suitable or willing to accept glasses or contact lenses and have the desire for refractive surgery;
The third category: excluding glaucoma and uveitis, diabetes, autoimmune diseases and other eye diseases.
ICL implantation has the advantages of stable or even improved postoperative visual quality, certain reversibility and wide correction range. Although this kind of lens implantation has many advantages, its disadvantages are also very obvious. Generally speaking, this kind of lens implantation has the following disadvantages:
One is that surgery is expensive. Generally speaking, the price of ICL crystal is around 35,000, and the most expensive smile for laser surgery is around 20,000. Obviously, it is equivalent to 70% more expensive than laser surgery, which is the first shortcoming of crystal implantation surgery.
The second is that there are usually complications after operation. These complications include the following aspects:
1, eye infection (called endophthalmitis);
2. Cataract: within seven years after operation, 1% to 2% of patients will have cataracts (older patients with higher myopia are at higher risk);
3. Glaucoma: lens implantation will cause the iris to release pigment, thus blocking the drainage system of the eye, increasing intraocular pressure and leading to glaucoma;
4. Retinal detachment (any intraocular surgery will increase the risk of retinal detachment at the back of the eye);
5. Accelerating normal corneal aging may cause it to become cloudy.
In a word, although ICL implantation has many advantages, its disadvantages are also obvious. If you want to do this kind of operation, you must think it over.
