I have had laser treatment to my right eye only about 20 years ago, it worked for me although I still have to wear glasses.
I was long-sighted with severe astigmatism in my right eye, without a corrective lens I couldn’t read the first line on the test chart, the best corrective prescription got me down to a fuzzy fourth line on the chart. A bit like looking through the bottom of an empty pint glass, and the lens was just as thick and heavy. The laser was one of only two in the country at the time capable of dealing with long-sight and the technique was experimental. The surgeon said because of defects to lens in my eye the best that could be achieved was that any corrective prescription would be simpler. The procedure involved using the laser to cut a rugby ball shaped scoop out of the cornea. The result was a slight improvement in vision, the prescription lens is thinner & lighter and I can have bi-focals (not possible before). The thing is I am now slightly short sighted in my right eye, long sighted in my left eye. But I still can’t shoot properly using my right-eye, (have had to adapt and shoot left-handed) and a curse on all those perverts who set weak shoulder stages. It's funny sometimes when I do try shooting weak shoulder, the RO's gets all excited, shouting "weak shoulder" as I put the gun to my right shoulder. I am thinking, didn't you just watch me shooting from the left on the strong shoulder stages.
None of that nonsense in CSR I am pleased to note.
