Surgery is a very common method for the treatment of cataract, including extracapsular cataract extraction and intracapsular cataract extraction. The incision of extracapsular cataract extraction is smaller than that of intracapsular cataract extraction. The turbid nucleus of lens is expelled and the cortex is sucked out, but the posterior capsule of lens is left. The posterior chamber intraocular lens can be implanted at the same time. The visual function can be restored immediately after the operation. Extracapsular cataract extraction has become the conventional operation method for the treatment of this disease.

Another kind of intracapsular cataract extraction is to remove the turbid lens completely from the eye. This operation requires a larger incision, because the lens capsule is removed at the same time, so the posterior chamber intraocular lens cannot be implanted at the same time.
