We present a review of keratorefractive and intraocular approaches to managing residual astigmatic and spherical refractive error after cataract surgery, including laser in situ keratomileusis (LASIK), photorefractive keratectomy (PRK), arcuate keratotomy, intraocular lens (IOL) exchange, piggyback IOLs, and light-adjustable IOLs. Currently available literature suggests that laser vision correc...

The femtosecond laser (FS) is the most interesting technical de velopment in laser refractive surgery during the last few years. This technique was developed to create flaps for laser in situ keratomileusis (LASIK). The FS is a focusable infrared (1053 nm) laser that uses ultrafast pulses in the 100-femtosecond (100 x 10 second) range. The laser delivers closely spaced spots that can be focused...

PURPOSE To assess and compare corneal modifications induced by IntraLase PulsionFS femtosecond laser and mechanical microkeratome Hansatome for laser in situ keratomileusis (LASIK) using the new-generation Heidelberg Retina Tomograph II (HRT II)/Rostock Cornea Module confocal microscope. METHODS In this case-control study, 24 eyes of 12 patients were examined with the HRT II in the follow-up ...

PURPOSE To check whether myopic LASIK induces changes on the posterior corneal surface. METHODS A Scheimpflug system (Pentacam; Oculus, GmbH, Wetzlar, Germany) was used to measure preoperative and postoperative posterior corneal topography in 27 eyes (of 14 subjects) that had undergone standard myopic LASIK surgery (attempted corrections between -1.25 and -8.50 D) and on 18 nonoperated eyes (...

OBJECTIVE To determine whether procedure room environmental conditions are associated with outcomes after myopic laser in situ keratomileusis (LASIK) or laser-assisted keratomileusis (LASEK). DESIGN Retrospective chart review. PARTICIPANTS Eight hundred sixty-three eyes of 458 consecutive patients at a university-based academic practice. METHODS We reviewed the medical records of consecut...

PURPOSE To study the long-term results of photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) in low to moderate myopic corrections using the Pulzar Z1 system (CustomVis), a 213 nm wavelength solid-state laser. SETTING University refractive surgery center. METHODS This prospective noncomparative case series comprised 20 patients (40 eyes) who had refractive surgery us...

PURPOSE The purpose of this study was to retrospectively compare the incidence of intraoperative flap complications, such as partial flaps, donut-shaped flaps, central corneal cuts, and complete caps with the Hansatome and Automated Corneal Shaper (ACS) microkeratomes. METHODS All laser in situ keratomileusis (LASIK) procedures performed by a single surgeon with the Hansatome or Automated Cor...

In this article, we use a longitudinal census of laser in situ keratomileusis (LASIK) eye surgeries collected directly from patient charts to examine the learning-by-doing hypothesis in medicine. LASIK surgery has precise measures of presurgical condition and postsurgical outcomes. Unlike other types of surgery, the impact of unobservable underlying patient conditions on outcomes is minimal. In...

PURPOSE To develop a computational approach to corneal biomechanical risk analysis in refractive surgery and to investigate its utility in an enigmatic case of unilateral ectasia after bilateral LASIK. METHODS Preoperative corneal elevation datasets from both eyes of a patient who developed unilateral post-LASIK ectasia were used to construct geometrically patient-specific, microstructurally ...

PURPOSE To report the outcomes of laser in situ keratomileusis (LASIK) in patients with a history of ocular herpes simplex virus (HSV) or herpes zoster ophthalmicus (HZO). SETTING Clínica Baviera, Instituto Oftalmológico Europeo, Madrid, Spain. METHODS In this retrospective case series, the records of eyes with a history of ocular herpes that had LASIK from 2003 through 2005 were reviewed. ...
