The purpose of the study was to evaluate the refractive results on a large cohort of patients who were implanted spherical or toric multifocal IOL's for cataract surgery or for refractive purpose. Preoperative refractive investigations included auto refractometer topography, pentacam, contact and noncontact biometry and many non-refractive investigations. The target in multifocal IOL usage was ...

PURPOSE To compare the effect of conventional phacoemulsification and femtosecond laser-assisted cataract surgery on the cornea using Scheimpflug imaging and noncontact specular microscopy. METHODS In each group, 38 eyes (38 patients) underwent cataract surgery using either femtosecond laser-assisted (Alcon LenSx laser) (femtolaser group) or conventional phacoemulsification (phaco group). Cen...

PURPOSE To explore the relationship between ablation parameters of myopic laser surgery and measurement area of wavefront aberration (WA) with Hartmann-Shack wavefront sensor. METHODS 58 subjects undergone myopic laser surgeries and 74 uncorrected myopic subjects were enrolled in this experiment. The laser ablation parameters were obtained from surgical records, which included spherical error...

Purpose: To compare changes in posterior corneal elevation, anterior chamber depth (ACD), anterior chamber volume (ACV) and corneal volume (CV) after laser in situ keratomileusis (LASIK ) and photorefractive keratectomy (PRK) for low to moderate myopia by pentacam imaging Methods: In this prospective comparative case series, 105 consecutive myopic eyes randomly scheduled for LASIK (n=59) or PRK...

PURPOSE To evaluate the technique, efficacy, and safety of posterior iris fixation of iris-claw intraocular lens (IOLs) implantation through a scleral tunnel incision for aphakia correction. DESIGN Noncomparative, interventional case series. METHODS A secondary posterior iris fixation of the Artisan iris-claw IOL (Ophthec BV, Groningen, The Netherlands) was implanted for aphakia correction ...

Purpose. To assess and compare the anterior and posterior corneal surface parameters, keratoconus indices, thickness profile data, and data from enhanced elevation maps of keratoconic and normal corneas with the Pentacam Scheimpflug corneal tomography and to determine the sensitivity and specificity of these parameters in discriminating keratoconus from normal eyes. Methods. The study included ...

PURPOSE To evaluate the agreement among three different optical methods in measuring anterior chamber depth (ACD), central corneal thickness (CCT), and pupil diameter. METHODS One hundred eyes of 50 healthy patients (25 men, 25 women) were enrolled in the study. Mean patient age was 25 years (range: 21 to 32 years). Exclusion criteria were history of any intraocular or corneal surgery, contac...
