Abstract: Objective To investigate the outcome of the wavefront-guided laser in situ keratomileusis(LASIK) in correcting low and midrange myopia. Methods The wavefront-guided laser in situ keratomileusis(W-LASIK) were performed on 48 eyes. The visual acuity, refraction and higher order aberration were determined pre-and post-operation, and the outcomes were compared with those of 42 eyes following standard-LASIK(S-LASIK). Results At 1 month after wavefront-guided surgery, compared with the BCVA of pre-operation, the UCVA was raised 2 lines in 3 eyes, 1 line in 16 eyes, was not changed in 24 eyes, and was decreased 1 line in 3 eyes. The outcomes were superior to those of the S-LASIK group. The coma following W-LASIK was lower than that following S-LASIK. In addition, the post-operative root mean square (RMSh) negatively related to the pre-operative vertical coma. Conclusions The wavefront-guided laser in situ keratomileusis can decrease the higher order aberration of myopia patients and increases the quality of vision.

Key words: Laser in situ keratomileusis, Wavefront aberration, Myopia
