Objective: To evaluate the effect of an aspheric LASIK refractive enhancement performed by relifting the original flap on the higher order aberrations (HOA) of the eye and the relationship between central corneal thickness (CCT) and intra-ocular pressure (IOP). Methods: Consecutive case series of 30 eyes requiring refractive enhancement from 1804 uncomplicated primary LASIK procedures performed in 2012. Flap relift and wavefront optimized ablation (Wavelight Allegretto Eye Q 400 Hz excimer laser) were performed in all cases. Pre-and post-operative examination included Shack-Hartmann aberrometry for 3 mm and 5 mm pupil sizes, CCT and IOP. Postoperative results at 1 year were compared to baseline values. Results: Changes in average values of coma, spherical aberration (SA), trefoil, CCT and IOP were not significant. Linear regression revealed significant associations between change (y) .. View More»
