Extracapsular cataract extraction

Extracapsular cataract extraction refers to microsurgery under coaxial light illumination. The surgical method is to puncture and tear off the central part of the anterior capsule, deliver the crystal nucleus, and use a simultaneous cataract injection needle to suck out the surrounding capsule. In the cortex, the intact posterior capsule and the surrounding anterior capsule are retained. The main advantage of external cataract extraction is that it retains the posterior lens capsule, which is convenient for implantation and fixation of intraocular lens. It is suitable for nuclear cataract in adults. At present, extracapsular extraction and intraocular lens implantation are the main surgical methods in developed regions.
