Comparison of the optical image quality in the periphery of phakic and pseudophakic eyes.
PURPOSE The natural lens may provide some compensatory optical effect in the periphery. When it is substituted by an IOL during cataract surgery, the quality of the peripheral optics will be modified. We compared the peripheral image quality in the eyes of patients with one eye implanted with a monofocal IOL and the fellow eye still with the natural precataract lens. METHODS We used a scannin...
متن کاملComparison of intravitreal bevacizumab treatment between phakic and pseudophakic neovascular age-related macular degeneration.
INTRODUCTION Before the era of intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment, only prevention for visual loss might have been achieved in a limited number of neovascular age-related macular generation (nAMD) patients with different treatment options. OBJECTIVE To compare the efficacy of intravitreal bevacizumab (IVB) for the treatment of nAMD between phakic and ps...
متن کاملLight exposure and macular pigment optical density.
PURPOSE Biochemical research has demonstrated that lutein and zeaxanthin, the two macular carotenoids, are bleachable pigments. Further, evidence suggests that exposure to UV light can degrade plasma carotenoid levels in vivo. The present study investigated the effects of exposure to normal levels of light on the levels of lutein and zeaxanthin in the retina. METHODS The optical density of ma...
متن کاملEstimation of macular pigment optical density in the elderly: Test–retest variability and effect of optical blur in pseudophakic subjects
The reproducibility of macular pigment optical density (MPOD) estimates in the elderly was assessed in 40 subjects (age: 79.1+/-3.5). Test-retest variability was good (Pearson's r coefficient: 0.734), with an average coefficient of variation (CV) of 18.4% and an intraclass correlation coefficient (ICC) of 0.96. The effect of optical blur on MPOD estimates was investigated in 22 elderly pseudoph...
متن کاملProgression of age related maculopathy in phakic versus pseudophakic eyes.
Age-related maculopathy (ARM) is one of the leading causes of central visual acuity loss in older western population. Many factors are responsible for the fast development of ARM. One of this is significant increases of optical radiations through artificial lens after removal of the catarctous lens. The aim of this study was to compare progression of ARM in phakic and pseudophakic patients and ...
