What kind of lens is installed in cataract surgery
Cataract is a common eye disease, which occurs in middle-aged and elderly people. Phacoemulsification and intraocular lens implantation are needed for cataract surgery. What kind of lens needs to be replaced needs specific analysis. If the elderly have low requirements for vision, they can replace the monofocal intraocular lens. If young people have high requirements for vision, economic conditions permit that multifocal intraocular lenses or trifocal intraocular lenses can be replaced.
