Purpose: The purpose of this study was to quantify the corneal power changes after wearing orthokeratology lenses different back optic zone diameters (BOZDs) and propose a novel 4-parameter model capable revealing associations between each parameter axial length growth (ALG). Methods: A prospective self-controlled conducted June 2022 December 2023. One eye in subject (N = 33) randomly assigned wear lens with BOZD either 5 mm (5 oz) or 6 (6 oz). Axial lengths were measured at 12 months ALG...
To investigate changes in refractive error schoolchildren before and during the coronavirus disease 2019 (COVID-19) pandemic. This study included 2792 students, who underwent a 3-year follow-up from 2018 to 2020. All participants yearly noncycloplegic refraction ocular examinations. Time-related sphere, cylinder, spherical equivalent (SE) measurements both genders were analyzed. The myopic sphere (− 0.78 ± 1.83 vs. − 1.03 1.91 D; P = 0.025) SE 1.04 1.90 1.32 1.99 0.015) progressed...
Purpose: To evaluate the visual performance in adolescents undergoing orthokeratology (OrthoK) treatment with two different optical zone diameters (OZDs). Methods: This randomized, double-masked, self-controlled prospective study was conducted at Tianjin Eye Hospital (Tianjin, China) June 2022. Thirty-six eligible schoolchildren were enrolled and fitted corneal refractive therapy lenses sizes of OZDs (5 mm [5OZ] 6 [6OZ]). Each participant randomized to wear 5OZ one eye 6OZ contralateral eye....
To obtain a continuous range of clear vision for pseudophakic eyes, design intraocular lens (IOL) with extended depth focus (EDoF) was proposed. The IOL optimized multi-configuration approach based on eye model and the optical performances designed were analyzed. modulation transfer function (MTF) values remain above 0.2 at 50 lp/mm object distance ranging from 0.35 m to infinity in both photopic mesopic over field 4°. stable when pupil diameter changes 2.25 mm 5 mm. Besides, presented...
<title>Abstract</title> Background To evaluate the effect of distant-image screen on myopia prevention and control. Methods Cross-designed randomized controlled trial. A total 40 children were recruited. The subjects randomly assigned to single-vision spectacle (SVS) lenses group or defocus incorporated multiple segments (DIMS) group.In each group, participants allocated tablet computer (TC)or (DIS)group, exchanged after 3 7 days. Participants asked watch videos for 90 minutes. Outcomes...
