The aim of this study was to determine the effect of laser refractive surgery on the offensive performance of professional baseball players.
Extensive search of the public media was conducted to determine which major league baseball players had undergone laser refractive surgery and when the procedure was performed. Baseball performance data were then used to determine presurgery and postsurgery baseball performance averages. A total of 17 position players were identified; however, 5 of these players were not considered in the analysis owing to insufficient playing experience either before or after the laser procedure.
No statistically significant or practically significant difference was found between the presurgery and postsurgery means on either on-base percentage (P = 0.31), batting average (P = 0.39), slugging percentage (P = 0.66) or on-base plus slugging (OPS; P = 0.997) of major league baseball players.
These preliminary findings suggest that professional baseball players should not expect a laser refractive surgical procedure to significantly improve their offensive baseball performance, despite the elimination of glasses or contact lens wear.
本研究的目的是确定激光屈光手术对职业棒球运动员进攻表现的影响。
对公共媒体进行广泛搜索，以确定哪些美国职业棒球大联盟球员接受了激光屈光手术以及手术时间。然后使用棒球表现数据来确定术前和术后的棒球表现平均值。总共确定了17名场上球员；然而，由于激光手术前后的比赛经验不足，其中5名球员未纳入分析。
美国职业棒球大联盟球员的术前和术后平均上垒率（P = 0.31）、击球率（P = 0.39）、长打率（P = 0.66）或上垒加长打率（OPS；P = 0.997）之间均未发现统计学上的显著差异或实际显著差异。
这些初步研究结果表明，职业棒球运动员不应期望激光屈光手术能显著提高他们的棒球进攻表现，尽管该手术可以让他们不再需要佩戴眼镜或隐形眼镜。
