PURPOSE To identify factors that can lead to corneal ectasia after laser in situ keratomileusis (LASIK). SETTING University refractive surgery center. METHODS In this retrospective study, the charts of all patients (2873 eyes) who had LASIK between May 1995 and November 1999 were reviewed. Fourteen patients (19 eyes, 0.66%) developed post-LASIK ectasia.(More)
PURPOSE To evaluate the long-term results of femtosecond laser-assisted anterior lamellar keratoplasty (FALK) for anterior corneal pathologies. DESIGN Retrospective, noncomparative, interventional case series. PARTICIPANTS Thirteen consecutive patients who underwent FALK for anterior corneal pathologies. INTERVENTION Femtosecond laser-assisted(More)
PURPOSE To report the technique and small case series results of femtosecond laser-assisted sutureless anterior lamellar keratoplasty (FALK) for anterior corneal pathology. DESIGN Retrospective, noncomparative, interventional case series. PARTICIPANTS Twelve consecutive eyes from 12 patients with anterior corneal scarring. INTERVENTION Femtosecond(More)
PURPOSE To evaluate long-term follow-up of Intacs microthin prescription inserts (Addition Technology, Inc, Fremont, California, USA) for the management of keratoconus. DESIGN A long-term (five years) retrospective, follow-up study. METHODS Seventeen eyes of 15 patients with keratoconus ages 24 to 52 years (mean age +/- standard deviation [SD], 34.0 +/-(More)
BACKGROUND Although the status of the axillary lymph nodes is widely accepted to be associated with prognosis in breast cancer patients, there is a need for biomarkers to be analyzed as indicators of responsiveness to treatment. The objective of this study was to test the hypothesis that the expression of apoptosis genes, bcl-2 and bax, predicts survival(More)
PURPOSE To measure the rigidity coefficient of a large number of subjects at clinically encountered intraocular pressures (IOPs) and to examine the possible correlation of ocular rigidity with other factors, such as the age of the patients, ocular parameters (axial length and corneal thickness), and pathologic conditions affecting the eye. METHODS The(More)
PURPOSE To discuss current applications and advantages of femtosecond laser technology over traditional manual techniques and related unique complications in corneal refractive surgical procedures, including LASIK flap creation, intracorneal ring segment implantation, astigmatic keratotomy, presbyopic treatments, and intrastromal lenticule procedures.

Pediatric keratoconus demonstrates several distinctive management issues in comparison with adult keratoconus with respect to under-diagnosis, poor compliance and modifications in treatment patterns. The major concerns comprise of the accelerated progression of the disease in the pediatric age group and management of co-morbidities such as vernal(More)
OBJECTIVE To review the published literature to assess the safety, efficacy, and predictability of femtosecond lasers for the creation of corneal flaps for LASIK; to assess the reported outcomes of LASIK when femtosecond lasers are used to create corneal flaps; and to compare the differences in outcomes between femtosecond lasers and mechanical(More)
PURPOSE To report the results of intrastromal corneal ring segment [ICRS] (KeraRing; Mediphacos, Belo Horizonte, Brazil) implantation using a femtosecond laser (IntraLase Corp, Irvine, California, USA) in keratoconic patients. DESIGN Retrospective, noncomparative, interventional study. METHODS Thirty-two keratoconic patients (50 eyes) who underwent ICRS(More)
