Objective: To investigate the effect of laser refractive surgery on night weapons firing. Methods: Firing range performance was measured at baseline and postoperatively following photorefractive keratectomy and laser in situ keratomileusis. Subjects fired the M-16A2 rifle with night vision goggles (NVG) at starlight, and with iron sight (simulated dusk). Scores, before and after surgery, were compared for both conditions. Results: No subject was able to acquire the target using iron sight without correction before surgery. After surgery, the scores without correction (95.9 ± 4.7) matched the preoperative scores with correction (94.3 ± 4.0; p = 0.324). Uncorrected NVG scores after surgery (96.4 ± 3.1) exceeded the corrected scores before surgery (91.4 ± 10.2), but this trend was not statistically significant (p = 0.063). Conclusion: Night weapon firing with both the iron sight and the NVG sight improved after surgery. This study supports the operational benefits of refractive surgery in the military.
