For myopic patients, wearing frames is the safest way of correction. However, for people with high myopia above 600 degrees, wearing glasses sometimes does not give them clear vision, and many of them suffer from distorted vision, dry eyes, easy fatigue, and in severe cases, dizziness, headache and nausea. Some people with high myopia are blocked by excimer laser surgery because of poor corneal quality. What to do? A few days ago, Wuhan University People’s Hospital Eye Center admitted a patient with myopia of more than 1,500 degrees in both eyes, and eventually restored her clear vision through a procedure called ICL (artificial crystal) implantation, also known as implantable contact lenses. The patient was 26 years old, with myopia of 1,500 degrees in both eyes and astigmatism. Because the myopia was too high to be corrected by glasses, and because the cornea was too thin to undergo excimer laser surgery, her double vision became more and more serious over a long period of time. After systematic examination, the doctor chose ICL implantation for her. The surgery took only about 20 minutes, and at the checkup the next day after the surgery, her vision had returned to 1.0, and there was no eye pain, eye swelling and other discomforts. ICL implantation is a new way of treating myopia with better results. While preserving the patient’s “original” crystalline lens, the IOL is implanted into the iris to correct high myopia, hyperopia and astigmatism without removing or destroying the corneal tissues, and there is no need for stitches after the surgery, and there are no adverse complications, such as dry eye and conical cornea. Adverse complications. Therefore, ICL implantation can be considered for highly myopic patients between the ages of 21 and 45 years old who are refractorily stable and free of other ocular diseases and serious underlying conditions. This technology is reversible, with ideal refractive correction, and can effectively make up for the shortcomings of laser surgery.
