73 yr old male with vision in one eye.. have cataract that is impacting life style. is it worth the risk for surgery and is laser surgery preferred?

Yes: Cataract surgery is really very easy now.

Cataract Surgery Ris: Depending on other risk factors (length of eye: if very short; history of other eye, h/o trauma, diabetes, on aspirin, flomax, (tamsulosin) general health, etc) cataract surgery is generally very safe and recommended in monocular (have vision in 1 eye only) pts. LENSX/Laser intralase surgery is generally the best option as it decreases many post operative issue/risks.
