Change with age of the refractive index gradient of the human ocular lens.
PURPOSE To study age-related changes in the refractive index distribution of the human ocular lens. METHODS Biometric data collected on 48 eyes in subjects ranging in age from 19 to 31 years and 48 eyes in subjects ranging in age from 49 to 61 years allowed estimation of a single parameter related to the refractive index distribution of the crystalline lens. The authors selected a gradient in...

Introduction: Today, Lasik surgery is one of the most common and effective procedures for correction of refractive errors. Less than 1% of patients undergoing Lasik operation suffer from serious and 3-5% suffers from mild complications. Also, results of lasik in most centers are promising. With the recent inauguration of the Lasik center of Yazd, it was decided to evaluate the results and compl...
متن کاملاندازهگیری همزمان ضریب شکست و ضخامت فیزیکی دستگاه‌های چندلایه‌ای با استفاده از نتایج مقطع‌نگاری همدوسی اپتیکی در فضای فوریه
In fourier domain optical coherence tomography, we can measure the optical thickness ( refractive index n times thickness d), to obtain the retinal layers in order to diagnose many disorders. In this work, we introduce a new method for measurement of refractive index and physical thickness of multiple layers simultaneously by Fourier domain optical coherence tomography, without additional infor...
