To investigate the incidence, culture results, treatment, and visual outcomes of infectious keratitis after laser in situ keratomileusis (LASIK) worldwide, the Cornea Clinical Committee of the American Society of Cataract and Refractive Surgery (ASCRS) contacted 8600 United States and international ASCRS members by e-mail and asked them to respond to a questionnaire about post-LASIK infectious ...

PURPOSE To describe recent technological additions to the NIDEK CXIII and Quest excimer lasers. METHODS A summary article with data from previous published studies outlining the benefits of newer technology. RESULTS The addition of a 1-kHz infrared eye tracker decreased the spread of laser spot placement from a mean of 228.79 microm without a tracker to 38.47 microm with the eye tracker. Th...

PURPOSE The aim of this study was to compare the changes in corneal biomechanical properties following small-incision lenticule extraction (SMILE) versus Q-value-guided femtosecond laser-assisted in situ keratomileusis (Q-FS-LASIK). METHODS In this prospective comparative study, patients with a sphere plus cylinder measurement of less than -10.00 D and cylinder measurement of less than -5.00 ...

PURPOSE To present the 1-year outcomes of combining monocular bi-aspheric ablation profile and contralateral monofocal LASIK in hyperopic patients with presbyopia. METHODS In this retrospective case series, 36 consecutive patients (72 eyes) who underwent simultaneous bi-aspheric ablation (PresbyMAX: SCHWIND Eye-Tech-Solutions GmbH and Co KG, Kleinostheim, Germany) in the non-dominant eye and ...

PURPOSE To describe postoperative laser-assisted in situ keratomileusis (LASIK) flap dislocation occurred after trauma METHODS Ultrabiomicroscopy (UBM) is used to obtain a high-resolution imaging of the cornea. RESULTS The UBM results are presented and compared with histologic and confoscan findings CONCLUSIONS The technique is useful and easy to perform, offering more opportunities to st...

A new procedure which combines LASIK and corneal cross-linking (Lasik Xtra®) has been proposed as an alternative to traditional LASIK. It is aimed at restoring strength to the cornea, increasing stability in visual outcomes, increasing the accuracy of the refractive correction, and potentially lowering enhancement rates. This article reviews the current clinical evidence which has been publishe...

We read with great interest the article by Kanellopoulos and Asimellis1 and the subsequent correspondence with Reinstein et al.2 with the debate regarding the law that drives epithelial remodeling and the healing process. Kanellopoulos and Asimellis explained their findings of epithelial thickening after myopic LASIK with their hypothesis that epithelial behavior is related to the biomechanics ...

BACKGROUND The purpose of this study was to evaluate surgically-induced astigmatism after spherical ablation in photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis (LASIK) for myopia with astigmatism < 1.00 D. METHODS The charts of patients undergoing spherical PRK or LASIK for the correction of myopia with minimal astigmatism of <1.00 D from 2002 to 2012 at the John A...

PURPOSE To evaluate changes induced by standard laser in situ keratomileusis (LASIK) for hyperopia on total and corneal optical quality. METHODS Total and corneal aberrations were measured before and after standard hyperopic LASIK in 13 eyes (preoperative spherical equivalent refractive error +3.17 +/- 1.10 D). The Chiron Technolas 217C laser with PlanoScan was used. Total aberrations (measur...

OCTOBER 2008 I CATARACT & REFRACTIVE SURGERY TODAY I 53 I n late 1999, IntraLase Corp. (now owned by Advanced Medical Optics, Inc., Santa Ana, CA) obtained a 510k clearance for its beta 6-kHz femtosecond laser to create LASIK flaps.1,2 The power of subsequent models increased to generation 1 (10 kHz),3,4 generation 2 (15 kHz),5 generation 3 (30 kHz),6,7 generation 4 (60 kHz)8 and, in April 2008...
