At present, the mainstream cataract surgery adopts phacoemulsification combined with intraocular lens implantation. This method has little damage and quick recovery. There is also advanced femtosecond laser-assisted phacoemulsification combined with intraocular lens implantation. Extracapsular cataract extraction combined with intraocular lens implantation and intracapsular cataract extraction combined with intraocular lens implantation are suitable for some special patients. There are also some special surgical methods, such as phacoemulsification combined with intraocular lens suspension, and the treatment cost is related to the choice of surgical methods and lenses.
