The most common surgical procedure for cataract surgery is cataract ultrasonic emulsification suction combined with IOL implantation. Patients can choose from aspheric multifocal IOL, aspheric monofocal IOL, astigmatism correcting IOL and so on according to their needs and symptoms. 1. Aspheric multifocal IOL: If the patient needs to drive or read books in normal times, has high visual requirements, and the financial condition allows, he/she can choose aspheric multifocal IOL, this kind of IOL satisfies the patients who have high requirements on the quality of life, and takes care of both distance and near vision. 2. Aspheric monofocal IOL: Patients who do not have too high requirements for visual quality can choose this type of IOL, which can only see far or near after surgery, and the price is relatively lower. 3. Astigmatism-correcting IOL: For patients with cataract and astigmatism, astigmatism-correcting IOL can be chosen. After cataract surgery, patients are advised to follow the doctor’s instructions, have regular checkups, and consult the doctor in time when discomfort occurs. Patients also need to pay attention to eye hygiene, do not rub the eyes with your hands, and when you wash your face and hair, you should avoid letting the water flow into the eyes, which may cause eye infections.
