Can cataract be operated on twice?

Cataract surgery usually does not show lens opacity. Cataract is mainly due to lens opacity caused by vision loss, in the mature stage after surgery can remove the turbid lens, intraocular lens implantation can improve the vision of the eye, and intraocular lens itself is not cloudy. After cataract surgery, the visual acuity is reduced again. It is considered to be after-cataract, mainly caused by residual cortex and posterior capsule opacity. It is recommended to go to the hospital for slit lamp examination to make a clear diagnosis, also called after-cataract. For the visual acuity caused by after-cataract, it does not need to be treated by secondary surgery, mainly after laser surgery to disperse the posterior capsule can improve the vision of the eye.
