To the Editor: Flap creation is the most crucial step of LASIK and the introduction of the femtosecond laser led to the production of uniform flaps enhancing the accuracy and reproducibility of LASIK.1,2 However, intrastromal corneal opacity (such as scar and haze) raised controversies regarding the efficacy of the technique in such cases because it can interfere with laser tissue disruption, c...

PURPOSE The aims of our study were to investigate whether laser in situ keratomileusis (LASIK) improves health-related quality of life (HRQoL) and to identify factors that affect postoperative HRQoL. MATERIALS AND METHODS A total of 213 Japanese patients who underwent primary LASIK were analyzed in this study. The average age of patients was 35.0±9.4 years. The subjects were asked to answer q...

BACKGROUND The aim of this study was to evaluate long-term efficacy, safety, stability, and predictability of photorefractive keratectomy (PRK) as treatment of astigmatism. MATERIAL/METHODS Ninety-four eyes of 52 patients, treated with PRK for compound myopic astigmatism, compound hyperopic astigmatism, and mixed astigmatism were studied during a 36-month period. Main outcome measures were un...

BACKGROUND Wavefront-guided Laser-assisted in situ keratomileusis (LASIK) is a widespread and effective surgical treatment for myopia and astigmatic correction but whether it induces higher-order aberrations remains controversial. The study was designed to evaluate the changes in higher-order aberrations after wavefront-guided ablation with IntraLase femtosecond laser in moderate to high astigm...
