Wondering if it's okay for an 82 year-old to undergo eyelaser treatment?

Ask Ophthalmologist. Your question is best addressed by Ophthalmologist. In general, eye surgeries are low risk procedures, at least from heart perspective. And vision is such an important aspect of living that I would be hard pressed to tell someone no. But bottom line, ask Ophthalmologist. Get 2nd opinion (another Ophthalmologist) if it'll make you feel better.
