摘　　要：目的探讨高海拔地区LASIK术后泪液的变化。方法对240眼LASIK术后4周泪液分泌量及泪膜破裂时间（BUT）进行测定。结果平均泪液分泌量≥10mm者14眼，占5．83％；平均泪液分泌量5～9mm者140眼，占58．34％；平均泪液分泌量〈5mm者86眼，占35．83％。BUT为15～35S者5例（10眼），占4．17％，BUT为15—10s者6例（12眼），占5．00％，BUT〈10s者109例（218眼）。占90．83％。结论高海拔地区LASIK术后对泪膜有一定程度的不良影响。发生机制与多种因素有关，术后适当的治疗，可减轻患者的眼部不适。Objective To investigate the changes in tear flow ＇after laser in situ keratomileusis （LASIK） at high altitude area. Methods Schirmer I experiment and tear fihn break-up time （BUT） determination were performed in 240 eye after LASIK. Resuits Mean values of Sehimer I were 〉 10 mm in 14 eyes （5.83%） ,it was 5 -9 mm in 140 eye（58.33% ） ,it was 〈5 nun in 86 eyes（35.83% ）. BUT was 15 - 35 s is 5 eases（ 10 eyes ,4.17% ）, 10-15s in 6 cases（12 eyes, 5.00%）, 〈 10s in 109 eases （218 eyes ,90.83% ）. Conclusion Laser in situ keratomileusis at high altitude area significantly alter the tear break-up time and Schirmer I test values.
