You can consider wearing glasses about three months after cataract surgery. You should not get wet within one week after cataract surgery and try to rub your eyes as little as possible to avoid the occurrence of infection. It is important to insist on medication for about two weeks to one month in order to promote the recovery of the wound and the post-operative reaction in the eye. At about three months after surgery, the position and structure of the lens are relatively stable, and the recovery of the cornea is also relatively stable. In some cases, there may be edema or inflammatory reactions in the cornea that may affect the optometry results. However, by three months, most people are basically stable and have recovered to a normal level, so it is a reasonable time for optometry to be performed at three months. Some people have a monofocal lens placed and may need a pair of glasses to meet the need to see near or far.
