Seventy-two Tactical Air Command (TAC) aircrew members completed one full year of soft contact lens (SCL) wear. A daily-wear regimen, using extended-wear lenses, was used to minimize corneal stress. Baseline measurements of visual acuity with SCLs and with spectacles after SCL removal and ocular indicator gradings were compared to measurements at 5-d, 10-d, 1-month, 3-month, 6-month, and 12-month examinations. Visual acuity did not decrease during the test. No aircrew member developed corneal ulcers or other serious complications requiring elimination from the test. Two aircrew members lost a total of 9 "duties not to include flying" (DNIF) days: one flyer was grounded for 1 d with a corneal abrasion and another for 8 d with epithelial microcysts. The TAC SCL Test, as designed, was generally successful. The conservative approach to SCL wear during the test and the meticulous follow-up care by United States Air Force eye care professionals most likely contributed to the low ocular complication rate.
第72战术空军司令部（TAC）的72名空勤人员完成了一整年的软性隐形眼镜（SCL）佩戴。采用每日佩戴方案，使用长戴型镜片，以尽量减少角膜压力。将佩戴SCL时的视力基线测量值、摘除SCL后使用眼镜时的视力测量值以及眼部指标分级与在第5天、第10天、第1个月、第3个月、第6个月和第12个月检查时的测量值进行比较。测试期间视力没有下降。没有空勤人员出现角膜溃疡或其他需要退出测试的严重并发症。两名空勤人员总共损失了9个“非飞行职责禁飞”（DNIF）日：一名飞行员因角膜擦伤停飞1天，另一名因上皮微囊肿停飞8天。按设计进行的TAC SCL测试总体上是成功的。测试期间对SCL佩戴采取的保守方法以及美国空军眼保健专业人员细致的后续护理很可能是眼部并发症发生率低的原因。
