LASIK (Excimer Laser) is widely used in myopia surgery today, but ICL implantation is superior for patients with high and super high myopia who are more eager to remove the “bottom of the bottle” lens. It can be placed in the safe area in front of the human eye lens and is only about 50 microns thick, thinner than the diameter of a hair, while the post-operative vision is better than wearing frames, contact lenses and other refractive correction techniques implemented on the cornea. ICL implants have been used in the United States since the 1990s and have been gradually promoted. In July 2006, ICL was approved by the Food and Drug Administration of the People’s Republic of China and allowed to enter the Chinese medical device market. It has been released to the domestic market in large quantities. Through unremitting efforts, we have received comprehensive technical support from foreign manufacturers, enabling this scientific research to be mastered by more ophthalmic medical institutions and to solve the long-standing eye problems for more myopic and astigmatic patients. ICL lens implantation can be done on an outpatient basis with only surface anesthesia, short surgery time, small incisions and no sutures, reducing the risk of inducing astigmatism. The post-operative recovery is quick and the patient’s quality of life is quickly improved. The surgery has been proven to have a high success rate. Even with high refractive error, it can be highly predictable, with good postoperative visual quality, very little regression, and high patient satisfaction. ICL implantation can be performed on a wide range of patients with myopia of 200-2500 degrees or hyperopia of 200-1000 degrees, as long as they are 20 years old or older, have a stable refractive status, and meet the conditions for the procedure through preoperative examination. ICL IOL implantation is considered one of the most promising refractive surgery procedures with good predictability, increased visual field, reversibility, ideal refractive correction, and preservation of the natural adjustment function of the lens. It is currently considered to be the newest and safest alternative to LASIK (excimer laser), PRK and other cutting procedures for refractive correction, and is now widely used in the United States. It can be used to correct a wide range of myopia, hyperopia and astigmatism without removing or destroying corneal tissue and without the need for post-surgical sutures. It also allows for predictable refractive correction and excellent visual quality. It is particularly effective in the treatment of high myopia. At present, most of the major ophthalmology centers and professional eye care institutions in China have taken the lead in ICL IOL implantation. The advantages of ICL treatment for high myopia are listed in detail: 1. Simple surgery, safe and fast: small surgical incision, surgery on the same day, discharge on the same day, and the crystal can be easily removed after surgery without changing the structure and shape of the eye tissue. 2. Wide range of correction without damage to the cornea: It can be used to correct a wide range of myopia, hyperopia and astigmatism without removing the cornea or destroying corneal tissue, without surgical suturing, and with excellent visual quality. 3, reversible, can be removed at any time: if the patient’s vision changes significantly and the ICL worn is no longer suitable, it can be removed or replaced at any time. 4.Since ICL is designed for long-term implantation inside the eye, no maintenance is required after surgery. 5. No foreign body sensation and good migration: After ICL implantation, no foreign body sensation will be felt in the eye and the implant will not be combined with any tissue structure. 6. Scientific design, practical and beautiful: ICL is implanted in the posterior chamber and fixed in the ciliary sulcus with a unique double-sided baked design, which does not touch the crystal or the iris and cannot be seen from the outside by outsiders or the eye itself, achieving perfection in cosmetology.
