Small trauma: Because the material of ICL crystal is soft and can be folded very small, it can be implanted in the eye through a smaller surgical incision, and the surgical incision does not need to be sutured; 2. Small foreign body sensation: Because ICL crystal is more compatible with human tissue, it has fewer adverse reactions such as rejection with the human body In addition, the foreign body sensation visible to the naked eye is smaller because the ICL crystal is implanted in the posterior chamber, so compared to wearing contact lenses, the ICL crystal is almost difficult to see with the naked eye, and the visual foreign body sensation is less; 3. Reversibility: If other problems occur in the eyes later, the implanted ICL crystal can be removed or even replaced. 2. Disadvantages: 1. relatively high price: ICL crystals are relatively expensive; 2. side effects: some patients will have a certain degree of soreness and swelling, and very few patients may have postoperative complications such as corneal edema and anterior chamber blood accumulation, which may also cause pre-cataracts, but the probability of occurrence is very small. after ICL crystal implantation, if pain, eye trauma, eye diseases, etc. occur, it is recommended to promptly consult a A professional doctor should be consulted for timely diagnosis and related treatment.
