A new form of aberrometry based on Tscherning optics has been proposed that captures the refraction and high-order aberrations of the eye with and without accommodation.
Experimental clinical optics study.
A green neodymium:yttrium-aluminum-garnet laser grid pattern is projected into the eye and viewed on the retina through a narrow, collimated aperture of 1 mm. The resulting aberrated pattern is photographically recorded in a normal eye in the unaccommodated and accommodated state through a pharmacologically dilated pupil without cycloplegia.
Detection of pupil-dependent refraction and high-order optical aberration with and without accommodation.
Subtle pupil-dependent errors in refraction and high-order aberrations (spherical aberrations and coma) are demonstrated in the unaccommodated normal eye. Accommodation reveals slightly more spherical power through the central 3-mm zone than through a 6.5-mm pupil without significant increase in aberration.
Tscherning aberrometry based on 'retinal imaging' is useful in defining the refraction and optical aberrations in a normal eye. Accommodation increases spherical refractive power with only small aberration changes, including negative asphericity.
提出了一种基于切恩宁光学原理的新型像差测量法，可在眼睛调节和未调节状态下获取其屈光和高阶像差。
实验性临床光学研究。
将绿色钕：钇铝石榴石激光网格图案投射到眼睛中，并通过1毫米的窄准直孔径在视网膜上观察。通过药物散瞳但未使用睫状肌麻痹剂，在正常眼睛的未调节和调节状态下，通过摄影记录产生的像差图案。
在调节和未调节状态下检测与瞳孔相关的屈光和高阶光学像差。
在未调节的正常眼睛中显示出与瞳孔相关的细微屈光误差和高阶像差（球差和彗差）。调节时，通过中央3毫米区域的球镜度比通过6.5毫米瞳孔时略高，像差无明显增加。
基于“视网膜成像”的切恩宁像差测量法有助于确定正常眼睛的屈光和光学像差。调节可增加球镜屈光力，且像差变化很小，包括负非球面性。
