The principle of ICL IOL implantation is to implant an artificial lens in the anterior chamber (or posterior chamber) of the patient’s crystalline eye to maintain the natural adjustment function of the lens and adjust the refraction at the same time. The advantages are that it is safe, predictable, and reversible. The procedure involves implanting an IOL into the eye through a tiny incision to correct vision. ICL surgery is another innovative technological achievement in the field of modern refractive surgery, which is approved by FDA, CE and China Food and Drug Administration. ICL surgery has a superior effect in the correction of ultra-high myopia that is incomparable to traditional excimer laser surgery, and its high efficiency and safety have been practiced in many clinics at home and abroad, opening up a new field of refractive surgery. ICL IOL implantation is the nemesis of super high myopia, allowing super high myopic patients to easily and permanently say goodbye to the “bottom of the bottle” glasses. Patients who are not willing to undergo laser corneal cutting. As long as the patient passes the strict preoperative examination, the postoperative visual acuity can meet or even exceed the preoperative expected corrected visual acuity.
