ABSTRACT
AIM:
To evaluate the clinical outcomes of combined wavefront - guided and aspheric laser in situ keratomileusis ( LASIK ) to correct myopia and myopic astigmatism.METHODS:
Prospective study. Forty-five patients ( 62 eyes ) with myopia and myopic astigmatism were randomly dividied into two groupsthe wavefront-guided and aspheric LASIK group and the wavefront- guided LASIK group. Safety, efficacy, predictability, ocular higher order aberrations(HOAs), and contrast sensitivity under mesopic condition were compared at 6mo postoperatively.RESULTS:
Both platforms had equal safety, efficacy and predictability. At 6mo after operation, total HOAs, spherical aberration and coma increased in both groups(P 0. 05 ), while contrast sensitivity in the wavefront-guided group recovered to preoperative levels at all spatial frequencies(P>0. 05).CONCLUSION:
Wavefront-guided and aspheric LASIK induced less HOAs and associated with better mesopic contrast sensitivity compared with wavefront - guided LASIK.
