Microkeratome flap may induce more higher-order aberrations than femtosecond laser flap

Microkeratome LASIK flap creation induced more higher-order aberrations than femtosecond flap creation, according to a study.“Hinge position did not appear to influence the induction of coma directly, contrary to previously pub­lished reports. The difference in aberrations induction between the two groups might be due to the differences in flap thickness profiles,” the study authors said.
