In the clinic, there is no refractive lens implantation myopia surgery which is better, the patient should choose the appropriate surgical method according to his/her own situation, such as IOL implantation, IOL replacement and so on. 1. IOL implantation: the principle of the surgery is to implant an artificial lens in the eye after removing the cataract to re-form a near-normal refractive whole, and the vision can be restored quickly after the surgery, which is suitable for patients with cataract in one eye or both eyes. 2. IOL replacement: By removing the cloudy crystal and replacing it with an artificial crystal, the refractive error can be corrected and vision restored, which is suitable for adult patients who are older and suffer from high hyperopia or myopia. When patients have the need for refractive lens implantation myopia surgery, it is recommended that they go to a regular hospital for treatment.
