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

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 ...

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

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 ...

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,
