To the Editor: During the past 3 years, several studies have suggested that small incision lenticule extraction (SMILE) is a promising alternative to LASIK for the correction of myopia. For this reason, we have read with great interest the article by Lin et al.1 about the comparison of the visual results after SMILE and femtosecond laser-assisted LASIK (FS-LASIK) for the treatment of myopia. Ho...

Background: To investigate the relationship between high-order aberration (HOA) changes and RCST/CT (residual corneal stroma thickness/corneal thickness) after femtosecond LASIK surgery.

PURPOSE To study the changes in posterior corneal elevation after laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) using Scheimpflug topography with the Pentacam anterior segment imaging system (Oculus, Inc.). SETTING Department of Ophthalmology, Albany Medical Center, and a private clinical practice, Albany, New York, USA. METHODS In this prospective study, 121 co...

PURPOSE To compare the outcomes of topography-guided and wavefront-optimized treatment in patients having laser in situ keratomileusis (LASIK) for myopia. SETTING Advanced Eye Centre, Post Graduate Institute of Medical Education and Research, Chandigarh, India. DESIGN Prospective contralateral-eye case study. METHODS Patients had topography-guided LASIK in 1 eye and wavefront-optimized LA...

Title: Topography-Based Screening for Previous Laser in Situ Keratomileusis for Myopia and Hyperopia Purpose: To develop a screening tool based on corneal topography to detect previous myopic and hyperopic laser in situ keratomileusis (LASIK). Settings: Clinical data from three private clinics analyzed in a university setting. Methods: 476 topographies (Orbscan II, Bausch & Lomb) were randomly ...

BACKGROUND In this study, we used a Pentacam® device to evaluate the corneal changes that occur after laser-assisted in situ keratomileusis (LASIK). METHODS Our study included 60 eyes of 32 patients. All patients were treated for myopia and myopic astigmatism using LASIK. The eyes were examined preoperatively and 3 months postoperatively using a Pentacam to assess corneal changes with regard ...

We report the first pilot qualitative confocal microscopic analysis of a laser in situ keratomileusis (Lasik) treatment combined with sequential high-fluence accelerated corneal collagen cross-linking, denominated Lasik XTra, by means of HRT II laser scanning in vivo confocal microscopy after a 6-month follow-up. After obtaining approval from the Siena University Hospital Institutional Review B...

PURPOSE To report national case-finding results for nontuberculous mycobacterial keratitis and describe its association with laser in situ keratomileusis (LASIK). DESIGN Enhanced passive disease reporting. METHODS In April 2001, we investigated a California cluster of Mycobacterium chelonae keratitis associated with hyperopic LASIK using a contact lens mask. To identify other possibly relat...

We describe a patient with flap decentration after laser in situ keratomileusis (LASIK) and subsequent phakic toric intraocular lens (IOL) implantation. A 19-year-old man with mixed astigmatism had LASIK in the left eye complicated by flap decentration. Laser ablation was abandoned and implantation of a phakic toric IOL was done. Ten months after IOL implantation, the uncorrected visual acuity ...

INTRODUCTION The field of refractive surgery continues to evolve amid continued concerns as to which surgical technique minimizes the risk of inducing ectasia. PURPOSE To compare clinical outcomes between PRK, LASEK and Epi-LASIK in moderately to highly myopic eyes (-4.00 D to -8.00 D). MATERIALS AND METHODS A retrospective chart review of 100 PRK eyes, 100 LASEK eyes (with alcohol) and 97 ...
