摘 要：Purpose To evaluate the changes in oc ular aberrations in-duced by corneal flap *** Prospective inter-ventional nonrandomized clinical t *** This study included 15patients who were schedu led for laser in situ keratomileusis.A nasal hinge flap w as created,using the Nidek MK -2000microkeratome and then replaced without performing laser *** ocul ar aberrations were measured before and after flap creation using the Nidek Optical Path Difference Scanning System ARK -*** The root mean square wavefro nt errors of the high-er -order optical aberrations(third -,fourth -,fifth -,and sixth -order aberrations)were not significantly altered at 1week postsurgery compared with t he preoperative val-ues(P 0.35).Conclusions Creating a corneal fla p with the Nidek MK -2000microkeratome did not induce chan-ges in higher-order optical aberrations as measured with the Nidek Optical Path Difference Scanning System ARK -10000during the early postoperativ e period.
