Abstract: Implantable contact lens (ICL) implantation is now gradually accepted as one of the correction methods for refractive errors with the continuous progress of modern refractive surgery. The incidence of complicated cataract after ICL implantation is about 2% ~ 3.5%, and cataract surgery is needed in severe cases (<1%). The early complication of cataract after ICL implantation is related to the operation, patient's age and diopter, while the late complication of cataract is mainly due to the contact between ICL and lens or the change of aqueous humor circulation. In recent years, the incidence of early postoperative complicated cataract has decreased significantly, which is related to the improvement of ICL material and design type, and the increase of surgical experience. Some studies suggest that the ideal vault of ICL should be between 250 μm and 750 μm. (Int Rev Ophthalmol, 2021, 45: 141-145)
