Fast recovery after cataract surgery, hospitalization time is related to the type of surgery, depending on the type of surgery the hospitalization time is different, the fastest can be discharged from the hospital after surgery, the slower will need about a week of hospitalization. 1. Intracapsular cataract extraction: This is a type of surgery in which the suspensory ligament of the crystalline lens is cut off and the crystalline lens is removed intact. This procedure is suitable for elderly cataracts with hardened crystals or dislocated crystals. It requires three days of preparation before the operation and the conjunctival sutures are removed five days after the operation, so a total hospitalization of about one week is needed. 2. Extracapsular cataract extraction: Through microsurgical techniques and closed suction, the anterior capsule is torn or incised, and the cataract nucleus and its cortex are removed, and the posterior capsule can be preserved intact. The procedure is indicated for adults with nuclear cataracts. The hospitalization time is shorter than that of intracapsular extraction and the damage is less than that of intracapsular cataract extraction. 3. Ultrasonic cataract emulsification: the lens nucleus is sucked out by ultrasonic pulverization, the operation time is short, the recovery is fast, and the patient can be discharged from the hospital after the operation, which is the cataract surgery with the least damage and the fastest recovery after the operation. After discharge, patients should avoid strenuous exercise and excessive bumps and strain, do not wash their face, do not rub their eyes to avoid causing anterior chamber hemorrhage, and follow the doctor’s instructions for eye-dotting and follow-up; meanwhile, pay attention to rest, avoid staying up all night and over-exerting their eyes.
