To determine the presence, type, and size of optical higher-order aberrations (HOAs) in professional athletes with superior visual acuity and to compare them with those in an age-matched population of nonathletes.
Vero Beach and Fort Myers, Florida, USA.
Players from 2 professional baseball teams were studied. Each player's optical aberrations were measured with a naturally dilated 4.0 mm pupil using a Z-Wave aberrometer and a LADARWave aberrometer.
One hundred sixty-two players (316 eyes) were evaluated. The HOAs were less than 0.026 mum in all cases. Spherical aberration C(4,0) was the largest aberration with both aberrometers. There were small but statistically significant differences between the aberrometers in mean values for trefoil C(3,3) and C(3,-3) and secondary astigmatism C(4,2). Although statistically significant, the differences were clinically insignificant, being similar at approximately 0.031 diopter (D) of spherical power. A statistically significant difference was found between the professional baseball players and the control population in trefoil C(3,-3). These differences were clinically insignificant, similar to 0.071 D of spherical power.
Professional baseball players have small higher-order optical aberrations when tested with naturally dilated pupils. No clinically significant differences were found between the 2 aberrometers. Statistically significant differences in trefoil were found between the players and the control population; however, the difference was clinically insignificant. It seems as though the visual system of professional baseball players is limited by lower-order aberrations and that the smaller HOAs do not enhance visual function over that in a control population.
确定具有卓越视力的专业运动员的光学高阶像差（HOA）的存在、类型和大小，并将其与年龄匹配的非运动员人群进行比较。
美国佛罗里达州的维罗海滩和迈尔斯堡。
研究了来自 2 支职业棒球队的球员。使用自然扩张的 4.0 毫米瞳孔，每位运动员的光学像差均使用 Z-Wave 像差仪和 LADARWave 像差仪进行测量。
评估了 162 名运动员（316 只眼睛）。在所有情况下，HOA 均小于 0.026 mum。两种像差仪均显示，球差 C（4.0）是最大的像差。在平均三叶草 C（3.3）和 C（3.-3）和二次散光 C（4.2）方面，两种像差仪之间存在较小但具有统计学意义的差异。尽管存在统计学差异，但差异在临床上无意义，大约为 0.031 屈光度（D）的球镜力。在三叶草 C（3.-3）方面，职业棒球运动员和对照组之间存在统计学上的显著差异。这些差异在临床上无意义，类似于 0.071 D 的球镜力。
当用自然扩张的瞳孔进行测试时，职业棒球运动员的高阶光学像差较小。两种像差仪之间未发现具有临床意义的差异。在运动员和对照组之间发现了三叶草的统计学显着差异；但是，差异在临床上无意义。似乎职业棒球运动员的视觉系统受到低阶像差的限制，较小的 HOA 并不能增强其视觉功能，超过对照组。
