Abstract:
AIM: To compare the visual effects of optimized aspheric transition zone Laser in situ keratomileusis (OAT z-LASIK )versus conventional Laser in situ keratomileusis (con. LASIK).METHODS: In a prospective study 44 patients (88 eyes)underwent OAT z -LASIK and 50 patients (92 eyes) received conventional LASIK surgery. Visual acuity,refractions、contrast sensitivity (CS),glare sensitivity (GS), and increment of Q-value after surgery were studied.RESULTS: All of operations on 94 cases were successful without severe complication after 3 months' follow-up. There was no significant difference in term of postoperative refractions between the two groups (t-test,P>0.05). The uncorrected visual acuity (UCVA), CS, GS, and increment of Q-value of OAT z group were significantly better compared to the tradition group 3 months after the surgery (P<0.05).CONCLUSION: OAT z - LASIK is a more effective procedure to improve visual quality compared to conventional LASIK.
