Corneal aberrations after small-incision lenticule extraction versus Q-value-guided laser-assisted in situ keratomileusis
Aim: To compare the changes in anterior corneal surface aberration characteristics after small-incision lenticule extraction (SMILE) versus Q-value-guided femtosecond laser-assisted in situ keratomileusis (Q-FS-LASIK) Methods: In this prospective comparative study, 102 patients with myopia and myopic astigmatism were divided between the SMILE and Q-FS-LASIK groups, consisting of 51 patients eac...
متن کامل[Laser in situ keratomileusis for correction of myopia].
OBJECTIVE To evaluate the efficacy and safety of laser in situ keratomileusis (LASIK) for the correction of myopia. METHODS A total of 429 eyes with preoperative refraction of -2.00 to -28.00 diopters were treated with LASIK and followed up for more than 12 months. Based on the refraction, the patients were divided into 3 groups: Group I, -2.00, to -8.00 diopters, 179 eyes; Groups II, -8.25 t...
متن کاملLaser in situ keratomileusis retreatment for residual myopia and astigmatism.
PURPOSE To evaluate the visual and refractive results of laser in situ keratomileusis (LASIK) retreatment on eyes with residual myopia with or without astigmatism. METHODS LASIK retreatment was performed on 35 eyes of 23 patients for correction of residual myopia, with or without astigmatism, with a mean manifest spherical equivalent refraction of -2.17+/-0.82 D (range, -1.00 to -3.87 D) and ...
متن کاملA comparison of CustomCornea myopia algorithms for wavefront-guided laser in situ keratomileusis.
OBJECTIVE To determine whether the new CustomCornea M3 (myopic astigmatism) algorithm places additional pulses in the periphery to counter excimer laser peripheral ablation inefficiency. METHODS Analysis of 25 myopic eyes of 18 patients that were within the approved indications for both the myopic astigmatism (M3) and myopic sphere (A7) algorithms. We analyzed ablation depth at peak and 4-mm,...
متن کاملCorneal irregular astigmatism after laser in situ keratomileusis for myopia.
AIMS To quantitatively evaluate the changes in corneal irregular astigmatism after laser in situ keratomileusis (LASIK) in relation to the amount of laser ablation. METHODS In 189 eyes of 116 patients undergoing LASIK for myopia, corneal topography was obtained before and 1 month after surgery. Using Fourier harmonic analysis of the topography data, corneal irregular astigmatism (asymmetry an...
