PURPOSE To assess the repeatability and reproducibility of central corneal thickness (CCT) measurements by high-resolution rotating Scheimpflug imaging (Pentacam, Oculus) and Fourier-domain optical coherence tomography (RTvue-100, Optovue) after laser in situ keratomileusis (LASIK) and to compare the agreement with ultrasound pachymetry (USP). METHODS(More)
PURPOSE To assess the precision of ocular biometry with a new noncontact optical low-coherence interferometer (Aladdin) in healthy subjects and patients with cataracts. SETTING Eye Hospital of Wenzhou Medical University, Wenzhou, China. DESIGN Observational cross-sectional study. METHODS Eyes from healthy subjects and eyes from patients with cataracts(More)
PURPOSE To determine the effectiveness of different interventions to slow down the progression of myopia in children. METHODS We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov from inception to August 2014. We selected randomized(More)
AIM To investigate the correlation between corneal biomechanical properties, applanation tonometry and direct intracameral tonometry. METHODS Patients scheduled for phacoemulsification were enrolled in this prospective observer-masked study. Central corneal thickness (CCT) was obtained with ultrasound pachymetry. Corneal biomechanical properties including(More)
PURPOSE To compare visual performance and wavefront aberration in high myopia implanted with an aspheric intraocular lens (IOL) and a spherical IOL. METHODS In this prospective investigation, 31 highly myopic patients were randomized to receive two IOL types: aspheric IOL (Acri.Smart 36A, 22 eyes) and spherical IOL (Rayner Superflex 620H, 23 eyes).(More)
PURPOSE To determine the repeatability and reproducibility of measurements of central corneal thickness (CCT) using optical low-coherence reflectometry (Lenstar LS900; Haag Streit) in normal eyes and post-femtosecond laser in situ keratomileusis (post-FS-LASIK) eyes and evaluate their agreement with ultrasound (US) pachymetry. METHODS CCT was measured(More)
OBJECTIVE To investigate the efficacy and safety of an iris-claw phakic intraocular lens (ICPIOL) implantation for high myopia. METHODS A consecutive group of 25 eyes in 13 patients with -7.88 to -22.88 diopters (D) of myopia was implanted with the Verisyse ICPIOL (AMO), and was examined preoperatively and 1, 7 days, 1, 3, 6, and 12 months(More)
PURPOSE To evaluate axial length (AL) measurement failure rate with the IOLMaster (Carl Zeiss AG, Germany) and Lenstar LS 900 (Haag-Streit AG, Switzerland) in eyes with cataract. METHODS Two hundred and ninety-six eyes of 170 patients with cataract were enrolled. Cataract type and severity were graded using the Lens Opacities Classification System III(More)
The relationship of corneal biomechanical metrics provided by the Ocular Response Analyzer (ORA) and Corvis ST (CVS) with physical intraocular pressure (IOPp) and central corneal thickness (CCT) was evaluated. Thirty fresh enucleated eyes of 30 rabbits were used in ex vivo whole globe inflation experiments. IOPp was measured with a pressure transducer and(More)
Purpose. To assess the repeatability and reproducibility of central corneal thickness (CCT) measurements by corneal dynamic Scheimpflug analyzer Corvis ST in normal eyes and compare the agreement with Pentacam rotating Scheimpflug System and ultrasound pachymetry. Methods. 84 right eyes underwent Corvis ST measurements performed by two operators. The(More)
