My 85 year old father is scheduled for some eye surgery described as: "Photodynamic Therapy with Visudyne for Macular Degeneration".

He has shown me a lengthy brochure about this from the eye clinic. There is a laser procedure, but also a shot of this Visudyne stuff involved. After the procedure he is not allowed any exposure to direct light, or light sources over 60 watts for two days. He has to wear gloves and hats and stay indoors in a darkened room for two days. According to the patients guide, the surgery "may or may not be successful" and "a deterioration in eyesight is possible".

My question is, does anyone have any experience with this treatment? Any insights?

I ask, because my father is not sure he wants this or needs it, but it was recommended to him by the eye clinic to which he goes.
