I had LASIK done 10 months ago. For 2 months it was not good, was not able to read or watch TV. After 3 months vision got better. I was able to watch TV and drive without discomfort. Now after 10 months vision got worse again with headaches, glares, very blurred vision. Before surgery I was -2,5 on both eyes, now I got prescription back to 0,5 on both eyes. Should I consider enhancement?
