Aging and Color Vision: A Model Using the Farnsworth‐MUNSELL 100‐Hue Test

Color Research &Application, EarlyView.
ABSTRACT Introduction This study examined the theoretical changes in the FM100 Hue scores induced by age‐related changes in the ocular media transmittance. These changes were analyzed with and without a von Kries‐type chromatic adaptation to determine the role of this adaptation process on age‐related changes in hue discrimination.

Controversies in intraocular lens implantation in pediatric uveitis

Journal of Ophthalmic Inflammation and Infection, 2016
Cataract is one of the most common and visually debilitating complications of pediatric uveitis. It develops as a consequence of chronic inflammation and steroid use and is seen most often in juvenile idiopathic arthritis (JIA)-associated uveitis ...

Effect of Photo‐Initiation Polymerization and Thermal‐Initiation Polymerization on the Reduction of Glistening in Hydrophobic Acrylic Intraocular Lens Materials

Macromolecular Chemistry and Physics, EarlyView.
Glistening is the condensation of water that forms within intraocular lens (IOL), which can degrade the patient's vision quality. Photo‐initiation and thermal‐initiation polymerization are widely used for the preparation of IOL materials. An interesting result is obtained that the glistening of photopolymerized IOL materials is much smaller than that ...

Biocompatibility of Intraocular Lenses

Türk Oftalmoloji Dergisi, 2017
The performance of an intraocular lens is determined by several factors such as the surgical technique, surgical complications, intraocular lens biomaterial and design, and host reaction to the lens.

Retropupillary iris claw intraocular lens implantation in aphakia for dislocated intraocular lens

International Medical Case Reports Journal, 2016
Background Nowadays, dislocated intraocular lenses (IOLs) and inadequate capsular support are becoming a challenge for every ophthalmic surgeon. Explantation of dislocated IOL and iris claw IOL (ICIOL) are the techniques that have been used in our ...

Clinical examples of correct orientation of a toric intraocular lens in patients with postkeratotomic corneal ectasia [PDF]

Клиническая практика
BACKGROUND: Surgical treatment of cataract in patients with postkeratotomic corneal ectasia has various features. First, difficulties arise when calculating the optical strength of an intraocular lens and its cylindrical component and determining the ...

Long-term follow-up of retropupillary iris-claw intraocular lens implantation: a retrospective analysis

BMC Ophthalmology, 2015
BackgroundThe ideal intraocular lens in cases of aphakia without capsular support is debated. Choices include anterior chamber lenses, iris- or scleral-sutured lenses, and iris-claw lenses.

Jackknife and bootstrapping resampling techniques to evaluate the precision of lens formula constants

Acta Ophthalmologica, EarlyView.
Abstract Purpose The purpose of this study was to develop a method for evaluating intraocular lens (IOL) formula constant uncertainties using two modern statistical techniques—jackknife and bootstrap resampling. Methods Using two datasets (dataset 1: 888 eyes treated with the aberration correcting Hoya Vivinex IOL, dataset 2: 821 eyes with the ...

Incidence and risk factors of rhegmatogenous retinal detachment following paediatric cataract surgery: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract To determine the incidence and identify risk factors of rhegmatogenous retinal detachment (RRD) following paediatric cataract surgery. This systematic review and meta‐analysis adhered to PRISMA guidelines and was registered in PROSPERO (CRD42024538383). A comprehensive search was conducted across multiple databases, including Cochrane CENTRAL,
