Under normal circumstances after cataract surgery to implant an artificial lens, the patient’s vision will be able to return to normal the next day. Cataract is a very common eye disease in ophthalmology clinics, and cataracts usually require surgical treatment. In addition to suctioning out the cloudy lens during surgery, an artificial lens needs to be installed, and the patient’s vision can return to normal only after the installation of the artificial lens. This is a very mature procedure, and most patients will be able to return to normal vision the next day after the implantation of the IOL. However, it is important to avoid rubbing the eyes for a period of time after the surgery and to avoid strenuous activities, and to pay proper attention to eye hygiene, so that the patient’s overall condition can return to normal only after one month.
