According to the integrity of lens capsule during lens extraction, it can be divided into two types: intracapsular extraction and extracapsular extraction.
Intracapsular cataract extraction and traditional extracapsular cataract extraction have become the past. For many years, extracapsular extraction with fine manipulation of surgical microscope has been used. With the popularization of microsurgery and the improvement of technology, modern extracapsular cataract extraction combined with intraocular lens implantation has become the most widely used surgical method. The operation requirements are relatively easy, the safety is high, the complications are few, and the effect of recovering vision after operation is good.
In recent years, small incision phacoemulsification has been carried out. There is no need to suture the wound after operation, and the wound heals quickly, with less postoperative astigmatism and rapid vision recovery.
