My 1986 experience with posterior capsulotomy was certainly painless and effective. However, seeing and hearing the sizzling inside my head as the capsule burning away was disconcerting. I said, "That sounds like bacon frying inside my head!"
I did have a whopper of a headache for some twenty-four hours and had quite the Draconian schedule with eye drops.
But the results! Stupendous!
I'm looking forward to getting better vision in my right eye. The last several weeks have been tedious as the field of vision on my right has been very cloudy, thus causing eye strain and reduced time on the web.
