PURPOSE
To report excellent and stable vision in an astronaut during space flight after bilateral cataract surgery with intraocular lenses.
METHODS
A 60-year-old physician mission specialist astronaut developed cataracts and underwent phacoemulsification with insertion of one-piece polymethylmethacrylate intraocular lenses that had 6-mm optics bilaterally. Several months later, he flew on a space shuttle mission. Ocular examinations were performed before and after the mission, and the patient was questioned about visual changes during flight.
RESULTS
Ocular examinations demonstrated stable bilateral posterior chamber intraocular lenses. Our subject reported excellent vision during liftoff, 18 days of microgravity, changes in cabin pressure, and reentry.
CONCLUSION
Results suggest that intraocular lenses are safe, effective, and well tolerated during space flight.
目的
报告一名宇航员在双侧白内障手术并植入人工晶状体后太空飞行期间视力良好且稳定的情况。
方法
一名60岁的医生任务专家宇航员患了白内障，接受了超声乳化手术，并双侧植入了光学直径为6毫米的一体式聚甲基丙烯酸甲酯人工晶状体。几个月后，他执行了一次航天飞机任务。在任务前后进行了眼部检查，并询问了患者飞行期间的视力变化情况。
结果
眼部检查显示双侧后房型人工晶状体位置稳定。我们的受试者报告在升空、18天的微重力环境、舱内压力变化和重返大气层期间视力良好。
结论
结果表明人工晶状体在太空飞行期间是安全、有效的，并且耐受性良好。
