Background: The Impact of Vision Impairment (IVI) questionnaire is used to assess vision-related quality of life (VRQOL) among patients with visual impairment. This study aims to evaluate the factor structure of the IVI in the context of Thai culture to assess psychometric properties.
Methods: This cross-sectional study was conducted between February and July 2022.
Background: Disability is globally recognized as a key cause of depression. Likewise, the COVID-19 pandemic has significantly increased the vulnerability of patients with low vision to health and health-related issues, especially mental health. This study aimed to examine the association between the impact of COVID-19 and depressive symptoms in patients with low vision and blindness.

Methods And Results: 48 IC staff, with age- and sex- matches 37 unexposed controls obtained eye examines. Posterior lens change was graded using a modified Merriam-Focht technique by two independent ophthalmologists.
Purpose: The purpose of this study was to evaluate the effect of pupillary dilation on the Haigis formula-calculated intraocular lens (IOL) power and ocular biometry measurements by using IOLMaster(®).
Methods: A prospective study was performed for biometry measurements of 373 eyes of 192 healthy subjects using the IOLMaster at the outpatient department of King Chulalongkorn Memorial Hospital from February 2013 to July 2013. The axial length (AL), anterior chamber depth (ACD), keratometry (K), and IOL power were measured before and after 1% tropicamide eye drop instillation.
Purpose: This was a prospective descriptive study to determine the changes in intraocular lens (IOL) position after neodymium-doped yttrium-aluminum-garnet (Nd:YAG) laser posterior capsulotomy by measuring anterior chamber depth (ACD) and refraction, including the spherical equivalent (SE) and cylinder.
Materials And Methods: Forty-seven pseudophakic eyes with posterior capsule opacification of 29 patients were included. Nd:YAG laser posterior capsulotomy was performed.
The aim of this study is to assess the agreement of IOL power and ocular biometry measurements before and after pupillary dilatation by using the IOLMaster. This was the prospective nonrandomized cohort study. Measurements were taken with the IOLMaster (®) (Carl Zeiss Meditec AG, Jena, Germany) from healthy volunteers at the Department of Ophthalmology, King Chulalongkorn Memorial Hospital.

Patients And Methods: This was a nonrandomized prospective cohort study. The AL, steepest K, flattest K, and IOL power of nondilated eyes were measured at the initial examination and later at 6 months by the IOLMaster.
Objective: To report the characteristics and the success rate of treatment of newly diagnosed amblyopia at Department of Ophthalmology, King Chulalongkorn Memorial Hospital between January 2007 and December 2007.
Material And Method: The authors performed retrospective chart reviews of 16 newly diagnosed amblyopic literate patients. Successful treatment was defined as having best corrected visual acuity (BCVA) > or = 3 Snellen lines improvement or > or = 20/30 in the amblyopic eye.
