I would like to know if the degree of nearsightedness in my "reading" eye would determine the sucess of the surgery when corrected for monovision? My right eye (dominant eye) is 20/20 and the left flucuates sometimes 20/80 sometimes 20/200. The dr. says that it does not matter how my left eye sees in terms of distance because it's function is for reading but I am having a very hard time adjusting to the blurriness when indoors. My surgery was ll/l9. Thanks

Your doc is right. You measured distance vision coule be anything. What matters is how good your near vision is. The more reading power a person needs (increases with age), the worse the distance vision is.
e.g. I have some 40 y.o monovision patients that see about 20/40 at distance. Some 60 y.o. patients see about 20/100 to 20/200 in their reading eye at distance.
The answer, then, is if your can read at near, and you can tolerate the difference between the eyes, then your surgery is successful. If not, then you need to discuss your problems with your surgeon.
