ICL lens implantation refers to posterior chamber type IOL implantation in crystalline eyes. After the failure of the surgery, patients can rest for a period of time for re-implantation, treatment of corneal complications, or choose to wear lenses and other treatments, which are related to the patient’s condition. ICL lens implantation is a treatment method to correct refractive error after implanting an IOL into the posterior chamber. If there is no damage to the structure of the patient’s eye after the implantation failure, the patient can rest for a period of time to evaluate the parameters of the IOL and the state of the eye, and can undergo surgery again after meeting the surgical criteria. If the implantation failure is complicated by corneal conjunctival damage and other complications, patients need to follow the medical advice to use tobramycin eye drops and other medications to control inflammation and promote recovery. Patients with corneal decompensation can be treated with corneal transplantation to improve their vision. If ICL implantation fails to correct refractive error and the patient refuses to undergo another surgery, the patient can also wear frames and corneal contact lenses to correct myopia and improve vision. Post-ICL patients are advised to follow the doctor’s instructions, have regular check-ups, and seek prompt medical attention when discomfort occurs.
