Going To Have Cataracts Removed, Want To Correct Distance Vision With The New Lenses. Inputs ?

I am going to have cataracts removed. I ve been nearsighted all my life and can still take off my glasses to read. I was hoping to correct my distance vision with the new lenses and just get used to having reading glasses handy everywhere, but my doctor thinks that I won t like that and should continue to have distance corrected with glasses and continue to not need them for up close activities since I ve been that way all my life. Any input?

Dear user
After cataract surgery, glasses are required for distance vision for correction of astigmatism induced by surgery and for any difference in the spherical power between power of intraocular lens implanted and actual power required. The usual amount of astigmatism induced by surgery depends on the type of surgery, with phacoemulsification accounting for +/- 0.5 dioptres andsmall incision incision cataract surgery accounts for =/- 1.0 dioptres.

Near vision is not possible after cataract surgery because of total loss of accommodation. Hence all patients require correction for near vision. However if you want to avoid glasses for near vision after cataarct surgery, you have to get multifocal intraocular lens or accommodative intraocular lens.
