PURPOSE The purpose of this study is to compare the magnitude and axis of astigmatism induced by a combined inferior oblique (IO) anterior transposition procedure with lateral rectus (LR) recession versus LR recession alone. METHODS Forty-six patients were retrospectively analyzed. The subjects were divided into two groups: those having concurrent inferior oblique muscle overaction (IOOA) and...

PURPOSE To evaluate the 5-year results of femtosecond laser-assisted refractive lenticule extraction (ReLEx-FLEx) for the treatment of myopia and myopic astigmatism. SETTING Departments of Ophthalmology, Helios Klinikum Erfurt, Erfurt, and Phillips Universität Marburg, Marburg, Germany. DESIGN Prospective clinical trial. METHODS This was a follow-up of a prospective study that evaluated t...

BACKGROUND To evaluate the 5-year results of Refractive Lenticule Extraction (ReLEx) as Small Incision Lenticule Extraction (SMILE) technique for treatment of myopia and myopic astigmatism. METHODS In 2008/2009, the worldwide first 91 eyes were treated using a novel surgical technique (SMILE), where a refractive lenticule of intrastromal corneal tissue is removed though a small incision compl...

OBJECTIVE To assess the preoperative central corneal thickness (CCT) of myopic and/or astigmatism patients presenting for refractive surgery in a tertiary hospital in Yemen. METHODS In this hospital-based cross-sectional study, 2,304 subjects aged 18-50 years with myopia and myopic astigmatism who presented to the refractive surgery unit were recruited. Data for the current study was collecte...

Purpose To compare surgically induced astigmatism (SIA) and refractive outcomes between two operation methods for late in-the-bag IOL dislocation. Methods In this prospective, randomized, parallel-group clinical trial, 104 patients (eyes) were assigned to IOL repositioning by scleral suturing 1.5- to 2-mm posterior to limbus (n = 54) or IOL exchange with a retropupillar iris-claw IOL using a ...

PURPOSE To evaluate the degree of static and dynamic cyclotorsion using a rotational eye tracker in laser in situ keratomileusis (LASIK) to correct myopic astigmatism. SETTING Rothschild Foundation, Paris, France. DESIGN Cohort study. METHODS Laser in situ keratomileusis with active iris registration using a Zyoptix 100 Hz excimer laser with Advanced Control Eyetracking was performed in e...
