Comparison of ocular biometry and intraocular lens power using a new biometer and a standard biometer.
PURPOSE To compare the repeatability and reproducibility of ocular biometry and intraocular lens (IOL) power obtained with a new optical biometer (AL-Scan) and a standard optical biometer (IOLMaster 500). SETTING Siriraj Hospital, Mahidol University, Bangkok, Thailand. DESIGN Prospective comparative study. METHODS Two independent operators measured eyes with cataract using both biometers....
متن کاملChanges in the anterior segment after cycloplegia with a biometer using swept-source optical coherence tomography
The aim of this study was to investigate changes in the anterior segment of the eye after cycloplegia. A biometer combined with swept-source optical coherence tomography (SSOCT) was used for measurements. Patients with strabismus or amblyopia who underwent cycloplegia were included. The axial length, central corneal thickness, anterior chamber depth, and lens thickness were measured with the bi...
متن کاملIntraocular lens power calculation after myopic and hyperopic laser vision correction using optical coherence tomography.
PURPOSE To use optical coherence tomography (OCT) to measure corneal power and calculate intraocular lens (IOL) power in cataract surgeries after myopic and hyperopic laser vision correction (LVC). METHODS Patients with previous LVC were enrolled in this prospective study at two centers (Doheny Eye Institute, Los Angeles, CA, USA and Cullen Eye Institute, Houston, TX, USA). Corneal power was ...
متن کاملThree-Dimensional Cataract Crystalline Lens Imaging With Swept-Source Optical Coherence Tomography.
Purpose To image, describe, and characterize different features visible in the crystalline lens of older adults with and without cataract when imaged three-dimensionally with a swept-source optical coherence tomography (SS-OCT) system. Methods We used a new SS-OCT laboratory prototype designed to enhance the visualization of the crystalline lens and imaged the entire anterior segment of both ...
متن کاملEstimation of Intraocular Lens Power Calculation after Myopic Corneal Refractive Surgery: Using Corneal Height in Anterior Segment Optical Coherence Tomography
PURPOSE To investigate the feasibility of estimating effective lens position (ELP) and calculating intraocular lens power using corneal height (CH), as measured using anterior segment optical coherence tomography (AS-OCT), in patients who have undergone corneal refractive surgery. METHODS This study included 23 patients (30 eyes) who have undergone myopic corneal refractive surgery and subseq...
