There is theoretically no age limit for LASIK surgery. But in practical reality, most patients age 65 years and above would have some degree of cataract and would be better serve by a cataract operation.
If you are 46 and suffer from myopia, presbyopia (lao hua) and astigmatism, you can go for LASIK or TransPRK.
For patients age 40 years and above, most eye surgeons will advise mono-vision laser vision correction where the dominant eye is corrected to see well for near and the non- dominant eye is corrected to leave a small amount of residual myopia (about 1.50 dioptre or 150 degrees) to see well for near.
The difference between the two eyes are deliberately kept at no more than 1.50 dioptres so that in this way, binocular vision is still preserved for both distance and near!
