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 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)
BACKGROUND We describe a modified method for deepitheliazation prior to corneal cross linking (CXL). The technique may overcome the current corneal pachymetric limitation parameter (over 400 microns) that is necessary for the safety of the procedure without affecting the overall benefits. METHODS In a series of two patients, with inferior topographic(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 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.

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 evaluate the outcomes and safety of a refractive inlay (Flexivue Micro-Lens, Presbia Coöperatief U.A.) for the corneal compensation of presbyopia. METHODS This prospective, interventional clinical study comprised 47 emmetropic presbyopes with a mean age of 52±4 years (range: 45 to 60 years). The inlay was inserted, centered on the line of(More)
PURPOSE To compare the ocular rigidity in vivo measurements of patients with age-related macular degeneration (AMD) and control subjects. DESIGN Prospective comparative clinical study. METHODS The pressure-volume relation and the ocular rigidity coefficient were compared among 32 patients with AMD (AMD group: 16 with neovascular and 16 with(More)
PURPOSE To evaluate the results of thin-flap laser in situ keratomileusis (LASIK) using a femtosecond-laser platform for flap creation. SETTING Institute of Vision and Optics, Faculty of Medicine, University of Crete, Heraklion, Greece. DESIGN Prospective interventional case series. METHODS Patients had LASIK with the FS200 femtosecond laser for flap(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)
