Macular Pigment and its Contribution to Visual Performance and Experience

Description : There is now a consensus, based on histological, biochemical and spectral absorption data, that the yellow colour observed at the macula lutea is a consequence of the selective accumulation of dietary xanthophylls in the central retina of the living eye. Scientifi c research continues to explore the...

Surgically Induced Astigmatism after Phacoemulsification with and without Correction for Posture-Related Ocular Cyclotorsion

Description : Purpose To report the impact of posture-related ocular cyclotorsion on one surgeon's surgically induced astigmatism (SIA) results and the variance in SIA. Setting Institute of Eye Surgery, Whitfield Clinic, Waterford, Ireland. Methods This prospective randomized controlled study included eyes that h...

Augmentation of Macular Pigment Following Supplementation with all Three Macular Carotenoids: an Exploratory Study

Description : Purpose:At the macula, the carotenoids meso-zeaxanthin (MZ), lutein (L), and zeaxanthin (Z) are collectively referred to as macular pigment (MP). This study was designed to measure serum and macular responses to a macular carotenoid formulation. Materials and Methods:Ten subjects were recruited into...

The Impact of Lens Constant Personalization on Refractive Outcomes Following Cataract Surgery Using the Haigis Formula

Description : Methods Personalization of Haigis IOL constants was performed using a series of 248 suitable eyes after biometry by partial coherence interferometry (IOLMaster) and IOL prediction based on optimized IOL constants derived from pooled data from the User Group for Laser Interference Biometry web site. ...

Macular Pigment Optical Density in an Aging Irish Population: the Irish Longitudinal Study on Ageing

Description : Purpose: The 3 carotenoids lutein, zeaxanthin, and meso-zeaxanthin, which account for the ‘yellow spot’ at the macula and which are referred to as macular pigment (MP), are believed to play a role in visual function and protect against age-related macular degeneration (AMD) via their optical and ant...

Augmentation of Macular Pigment Following Implantation of Blue Light-Filtering Introcular Lenses at the Time of Cataract Surgery

Description : PURPOSE. (Photo)-oxidative stress is believed to play a role in the pathogenesis of age-related macular degeneration (AMD), with the threshold for retinal damage being lowest for short-wavelength (blue) light. Macular pigment (MP), consisting of the carotenoids lutein (L), zeaxanthin (Z) and meso-Z,...

The Impact of Macular Pigment Augmentation on Visual Performance in Normal Subjects: COMPASS

Description : This study was conducted to investigate whether augmentation of macular pigment (MP) enhances visual performance (VP). 121 normal subjects were recruited. The active (A) group consumed 12 mg of lutein (L) and 1 mg of zeaxanthin (Z) daily. MP optical density (MPOD) was assessed by customized het...
