Anterior Segment Biometry during Accommodation Imaged with Ultralong Scan Depth Optical Coherence Tomography
Purpose: To measure by ultralong scan depth optical coherence tomography (UL-OCT) dimensional changes in the anterior segment of human eyes during accommodation.Design: Evaluation of diagnostic test or technology.Participants: Forty-one right eyes of healthy subjects with a mean age of 34 years (range, 22–41 years) and a mean refraction of −2.5±2.6 diopters were imaged in 2 repeated measurements at minimal and maximal accommodations.Methods: A specially adapted and designed UL-OCT instrument was used to image from the front surface of the cornea to the back surface of the crystalline lens. Custom software corrected the optical ...
