I don't like to do a Yag Cap for PCO unless the person is symptomatic and has complaints. That is the way most ophthalmologists do it
My ophthalmologist saw the pco starting and told me we would take care of it if and when my vision deteriorated. At my 6 months checkup we mutually agreed it was time. Halos from lights, loss of couple lines on eye chart. Was like cataract was back. It was really not a big deal to have it done, but no sense having it done with no symptoms. IMO of course.
