IOL implantation, or ICL for short, is maintenance-free because it is implanted inside the eye for a long period of time, and the implanted ICL does not bind to any tissue structure or move. ICL can meet the needs of patients with high myopia with other non-surgical changes in vision and refractive errors, as well as patients with unequal vision in both eyes. In addition, ICL has a unique double-sided arch design that is fixed in the ciliary sulcus and does not touch either the lens or the iris, making it impossible for anyone, including the patient, to see it from the outside. There is no need to worry about those worries of wearing glasses. ICL procedure】 The ICL treatment process is divided into three parts, first is the pre-operative examination and preparation, then is the appointment to schedule the surgery, and finally is the post-operative recovery period treatment and follow-up. Pre-operative examination: basically the same as LASIK examination, except that ICL implantation does not require corneal topography examination, but additional corneal endothelial function examination and anterior chamber depth examination. IOL implantation channel: After the examination, if the patient is eligible for surgery, the doctor will input the refractive error related data, anterior chamber depth, corneal curvature and corneal diameter of the myopic patient for ICL implantation into a special computer software, and through precise calculation, the patient will be implanted with the type of lens, and the ICL lens will be officially ordered by fax or other means. After the ICL arrives, the surgery can be scheduled. Procedure: The procedure is not complicated, safety is very important and must be operated by a physician with skillful microsurgery skills and extensive surgical experience. The procedure is performed through a minimally invasive incision at the edge of the cornea, and the collapsible, reduced ICL is simply implanted into the eye through a special pusher and fixed in the ciliary sulcus behind the pupil. The procedure takes only about 30 minutes, and a small number of patients may experience slight eye swelling during the procedure. Post-operative care: After the patient’s surgery, after resting with the eyes closed for 2 to 4 hours, the doctor will conduct the first post-operative examination and treat the patient accordingly, giving the patient some medications to prevent infection and control post-operative reactions, as appropriate. The first postoperative day, one week postoperatively and one month postoperatively will be reviewed in the hospital. After the surgery, eye drops need to be ordered for one to two weeks, which is the whole treatment process of ICL implantation. The latest progress of ICL at home and abroad, according to the U.S. FDA clinical validation report on the ICL implantation program, showed that among patients who underwent ICL implantation, the naked eye visual acuity of patients with mild to moderate myopia after ICL surgery exceeded the standards required by the FDA and met or exceeded the results of all LASIK clinical studies. In terms of surgical predictability, for the 800-1400 range, ICL results are more predictable than all currently approved excimer devices.
