my mom had a cataract surgery she used to take daily dosage of UNISTAR 75 which contains aspirin in it but doctor said not to take it for a week. what is the reason behind it ?

1 Answer 1


Aspirin has a "blood thinning" effect; it inhibits platelet aggregation. Therefore, it gives a higher risk of bleeding in the period surrounding the surgery.

I have not found a review about specifically cataract surgery, but this large trial (>10000 patients) shows that in noncardiac surgeries, aspirin gives an increased risk of major bleeding.
