The dynamics of the pre-corneal tear film topography are studied on 21 subjects with a purpose-built lateral shearing interferometer. Interesting tear topography features such as post-blink undulation, break-up, eyelid-produced bumps/ridges, bubbles and rough pre-contact lens tear surfaces were recorded. Using the calculated tear topography maps, the effects of the tear dynamics in visual performance, refractive surgery and ophthalmic adaptive optics are discussed in terms of wavefront RMS. The potential of lateral shearing interferometry for clinical applications such as dry eye diagnosis and contact lens performance studies is illustrated by the recorded topography features such as post-blink undulation, break-up, eyelid-produced bumps/ridges, bubbles and rough tear surfaces in front of contact lenses.
使用特制的横向剪切干涉仪，对21名受试者角膜前泪膜地形图的动态变化进行了研究。记录了一些有趣的泪膜地形图特征，如眨眼后的波动、破裂、眼睑产生的凸起/嵴、气泡以及接触镜前粗糙的泪膜表面。利用计算得到的泪膜地形图，从波前均方根的角度讨论了泪膜动态变化在视觉性能、屈光手术和眼科自适应光学中的作用。记录的地形图特征，如眨眼后的波动、破裂、眼睑产生的凸起/嵴、气泡以及接触镜前粗糙的泪膜表面，说明了横向剪切干涉术在干眼诊断和接触镜性能研究等临床应用中的潜力。
