摘要

我们展示了一种潜在视力测试仪（PVT），旨在研究和提高老化眼睛视力（VA）测量的准确性。主要功能包括麦克斯韦视图下的高分辨率视觉显示器，用于限制波前（WF）像差的3毫米瞳孔，用于量化眼像差的哈特曼夏克波前传感器，以及用于校正光学像差的可变形镜。在每个试验中，视差测量使用四种不同的强迫选择来测量单个黑对白E刺激，并对眼像差进行三种不同程度的校正。对于视力正常的受试者，当二级以上的高阶像差被纠正时，VA并没有明显改善。

Potential vision tester using Maxwellian view, small pupil, and different levels of wavefront correction with adaptive optics.

We demonstrate a potential vision tester (PVT) designed to study and improve the accuracy of visual acuity (VA) measurements in the aging eye. Key features include a high-resolution visual display presented in Maxwellian view, a 3 mm pupil to limit wavefront (WF) aberrations, a Hartmann Shack wavefront sensor to quantify the ocular aberrations, and a deformable mirror to correct optical aberrations. VA was measured using four alternative forced choices for a single black-on-white E stimulus in each trial, with three different levels of correction for the ocular aberrations. For normally sighted subjects, VA was not significantly better when higher-order aberrations beyond second order were corrected.
