Fundus biomicroscopy is the clinical standard for comprehensive stereoscopic examination of the posterior segment of the eye.
Double aspheric hand-held condensing lenses provide excellent stereopsis and a uniformly illuminated wide-field image of the vitreous, retina and choroid. Although there is adequate visualization of vitreous structure, reflectance, and optical lens aberrations, including pupil aberrations, impose limitations on the resolving capabilities of the observation system.
Fundus biomicroscopy using the Volk Superfield NC lens provides a superior view of the vitreous structure and a stereoscopic, wide field of view of the structures of the retina and choroid, including a detailed view of the optic disc and macula.
This paper describes the new Volk Superfield NC lens and presents an overview of the high quality imaging capabilities and clinical application of the lens especially with respect to vitreous examination.
眼底生物显微镜检查是眼部后段全面立体检查的临床标准。
双非球面手持聚光透镜可提供出色的立体感以及玻璃体、视网膜和脉络膜均匀照明的宽视野图像。尽管玻璃体结构、反射率以及包括瞳孔像差在内的光学透镜像差有足够的可视化效果，但这些像差对观察系统的分辨能力造成了限制。
使用 Volk Superfield NC 透镜进行眼底生物显微镜检查可提供玻璃体结构的优越视图以及视网膜和脉络膜结构的立体宽视野，包括视盘和黄斑的详细视图。
本文介绍了新型 Volk Superfield NC 透镜，并概述了该透镜的高质量成像能力及其临床应用，特别是在玻璃体检查方面。
