Does intraocular lens implantation hurt?

Cataract surgery does not require general anesthesia, nor does it require injection anesthesia. Just drop a few drops of topical anesthetic before surgery, that is, a special eye drops. After dropping it, you will not feel any pain. The doctor can perform the surgery. During the whole operation process, the patient is very clear. He can clearly sense every step of the operation. During the operation process, if the patient still feels a little pain, then he can directly tell the doctor at this time. A normal doctor would stop and drop one more drop of topical anesthetic, that is, order this eyedrop again, so that the patient would feel much more comfortable, and then he could continue the operation.
