hahaha, i find this eye doctor friend of your brother really need to go back to school again.
even with my poor eyesight of -900, they were corrected down to -50, which was the original target, since i am already over 40, already have minor 老花, not suitable to correct to 0.00.
with the Intralase technology today, surgical correction can reduce to within 100, how would the eye surgeon allow " 如果保留二百度為第時減低老花程度 " ????? really talking nonsense.
furthermore, i don't think any of us will wear 老花 spectacles to play sports, watch movie, eat meals, etc
"真係有風險" that i will agree, which is why you definitely need to find a good doctor to assess your eyes correctly.
the recommendation is to remove contact lens at least 7 days prior to eye examination, and 7 days again prior to eye surgery.
some people complete everything in one go, so " 7 days prior to eye examination, and then wear spectacles for 1-2 more days and go ahead with eye surgery "
