IHP -- How long has it been since your surgery? Most people don't know this, but ANY surgery can affect eyesight for 6 months or more. For an example, in Sept, '01, I had heart bypass surgery. I'd managed to qualify for the Shooter of the Year competition in March, '02. I shot the normal course on Sat & did well, but on Sunday in the SOY competition, it was if someone had removed the sights from my rifle -- could NOT see them at all. There was another competition right after the SOY, & the sights were back, so I shot well again. I asked my Optometerist & he said that was a normal thing. I needed my glasses updated, but he declined even looking at me untill it was at least 6 months after surgery. If it's been 8 or 10 months since you got your eyes "fixed", then you might have something else going on & need to check with your Doc.
