There is no authoritative information stating that patients aged 43 years old cannot undergo ICL implantation for myopia. If the patient does not have glaucoma, shallow anterior chamber, atrial angle abnormalities and other abnormalities, and meets the criteria for surgery, and has a strong will to remove the lens, then the surgery is feasible, but the patient needs to pay attention to postoperative care. The age of 43 is not a contraindication for ICL IOL implantation. If the patient meets the surgical criteria and has a strong desire to undergo surgery, ICL IOL implantation can generally be performed to improve vision. ICL IOL implantation is mainly used to correct the patient’s vision by implanting an IOL, and does not require any stitches after the surgery. However, if the patient suffers from glaucoma or has shallow anterior chamber, anomalous chamber angle, peripheral anterior iris adhesion, etc., ICL IOL implantation is not suitable for the patient, and the risk of postoperative complications is higher. It is recommended that myopic patients should consult a doctor in time to assess their condition and choose the appropriate treatment under the doctor’s guidance.
