What if a patient had LASIK, will this change NRA/PRA?

@optometry-with-samir 7 месяцев назад

We do it with correction, LASIK surgery is also a type of correction. If after LASIK patient is emmetropic then we can proceed with the test. If after LASIK patient is having Refractive error then we have to correct leftover refractive error and the proceed with the test.

While doing PRA with minus lens is it good to having 2 lenses in one eye? I have studied " Remove one lens then only put the other minus lens"

@optometry-with-samir 11 месяцев назад

Removing 1st lens after placing 2nd lens can be problematic for ill sustain accommodative patient. A patient with normal accommodative response can easily absorb this change of power while placing 2nd lens and removing 1st lens.. Changing of the lens is done in less than 1sec so it won't be any problem. If you have materials related to that you can share with me: samirsutradhar0@gmail.com Thank you, Samir Sutradhar.
