Corneal biomechanical properties in normal, regular astigmatic, and keratoconic eyes
Corneal hysteresis (CH) is a parameter which measures the viscoelastic behaviour of the cornea, indicating its biomechanical integrity1. Some clinical conditions such as keratoconus, Fuchs corneal dystrophy, high myopia, glaucoma and corneal refractive surgery, may induce changes in corneal biomechanical properties, leading to a decrease in CH2-6. Astigmatism, a refractive error related to corn...
متن کاملThe biomechanical properties of the cornea and anterior segment parameters
BACKGROUND To investigate the biomechanical properties of the cornea measured with the Ocular Response Analyzer (ORA) and their association with the anterior segment parameters representing the geometric dimensions including the corneal volume and anterior chamber volume. METHODS A retrospective review of 1020 patients who visited the BGN Eye Clinic was done. The mean radius of the corneal cu...
متن کاملBiomechanical properties of the cornea in high myopia
PURPOSE To determine corneal biomechanical properties in patients with high myopia. DESIGN Observational study. METHODS High myopia patients (n=45, age: 37.0+/-12.6 years) with refractive errors of spherical equivalent (SE) greater than -9.00D were recruited in this study along with healthy subjects (n=90, age: 33.7+/-12.4 years) with refractive errors of SE ranging from 0D to -3.00D. Only ...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولEffects of pterygium on the biomechanical properties of the cornea: a pilot study.
OBJECTIVE To investigate the changes induced by a pterygium or its surgical removal on the biomechanical properties of the cornea and to determine factors that might affect these parameters. METHODS This prospective pilot interventional, non-randomized, observer-masked study included 20 eyes of 20 patients with a unilateral primary pterygium (pterygium group) and 19 fellow healthy eyes (contr...
