Article Abstract
The International Commission on Radiological Protection recommended a significant reduction of the equivalent dose limit for the eye lens. Reportedly, medical staff in charge of diagnostic imaging procedures may exceed the new dose limits for the eye lens. The use of dosimeters dedicated to the eye lens remains low, and dosimeters for the neck region were often used to assess eye lens doses. However, measurements by neck badges may overestimate or underestimate the recommended eye lens doses because the height of the neck differs from that of the eye. This study aimed to evaluate the air dose distribution in the vertical plane to understand the difference between neck and eye doses. H*(10) in the height of the eye position was 52.8% lower than that in the height of the neck position in the under-table position. Thus, the equivalent eye lens dose evaluated using a neck badge dosimeter may be overestimated.

Predictors of Post-treatment Visual Improvement After Bacterial Keratitis Infection at a Referral Center in Southern California.
Cornea
September 2025
Department of Ophthalmology, University of California Los Angeles, Los Angeles, CA.
Purpose: To evaluate visual outcomes after bacterial keratitis (BK) and identify predictive factors for poor prognosis at a tertiary referral center in Southern California.
Methods: This is a cross-sectional retrospective review of patients' medical records with culture-positive BK at University of California Los Angeles from January 1, 2014, to December 31, 2019. Main outcome measure was change in best-corrected visual acuity (BCVA) at 12 weeks posttreatment.
Presbyopia-correcting intraocular lenses in eyes with corneal conditions: an update.
Curr Opin Ophthalmol

Singapore Eye Research Institute, Singapore National Eye Centre.
Purpose Of Review: Modern presbyopia-correcting intraocular lenses (IOLs) offer a potential solution to address the rising postoperative demand and expectations for spectacle independence following cataract surgery. However, IOL calculation and selection becomes more complex when presented with previous corneal refractive surgery (CRS) or co-existing corneal conditions. This review explores the use of presbyopia-correcting IOLs in eyes with co-existing corneal conditions or surgically altered corneas.

Phacoemulsification with intraocular lens (IOL) implantation has become the standard method for cataract extraction regardless of its etiology. In modern phaco surgery, implantation of multifocal IOLs is considered the most advanced method for correcting aphakia following lens extraction. The wide range of available multifocal IOLs is promoting the ongoing discussion regarding the advantages of each type, as well as potential strategies for optimizing surgical outcomes.

The ocular surface microbiome (OSM) is a low-density, low-diversity microbial ecosystem influenced by host and environmental factors, including age, hygiene, contact lens use, and systemic disease. Unlike other mucosal sites, the eye lacks a well-defined core microbiome, and its microbial composition varies significantly between individuals. Advances in metagenomics have revealed that commensals such as and may contribute to immune regulation and homeostasis.

Jinan University, Guangzhou, Guangdong, China.
Purpose: This study aims to explore the factors influencing refractive error following Phacoemulsification combined with intraocular lens implantation (PE + IOL) in patients with primary angle-closure glaucoma (PACG), providing a theoretical basis for preoperative consultation and IOL power selection in clinical practice.
Methods: A retrospective analysis was conducted on 404 PACG patients from Shenzhen Eye Hospital between 2019 and 2024. Preoperative ocular biometric parameters and combined surgical approaches were evaluated using Spearman correlation, multinomial logistic regression, and receiver operating characteristic (ROC) curve analysis.
