Abstract
Objective To compare the clinical curative effect of corneal wavefront-guided combining Q-value guided aspheric keratctomy excimer LASEK for high myopia of thin cornea ( 500μm). Methods Of selected 25 high myopia of thin cornea (42 eyes), and 38 high myopia of thick cornea (65 eyes), compared the preoperative uncorrected visual acuity (UCVA), age, corneal thickness, atherectomy thickness,remnant thickness, spherical equivalent (SE), Coma-like RMS (root of mean square), spherical-like RMS,RMSg (root of mean square of general aberration) with postoperative UCVA of 2, 4 weeks, 1 month, 3, 6 months SE, Coma-like RMS, spherical-like RMS, RMSg, Level of Haze. Results There were no statistically significant differences between two groups 6 months aiter operation in UCVA, spherical equivalent (SE),Coma-like RIMS, spherical-like RMS and RMSg. Both groups showed high safety, efficacy, predictability and the same clinical curative effect. Conclusions Aspheric keratectomy excimer LASEK for high myopia of thin cornea and corneal wavefront-guided combining Q-value guided LASIK for high myopia of thick cornea have the same clinical curative effect. Key words: Thin cornea; High myopia; Asphcric keratectomy excimer Laser in situ keratomileusis (LASIK); Laser subepithelial keratomileusis (LASEK); Aberration
