PURPOSE
To investigate the impact of laser in situ keratomileusis (LASIK) on the change in pupil size immediately after the procedure.
METHODS
In a prospective study, measurement of pupil size was assessed in 70 eyes of 35 consecutive patients using a hand-held pupillometer before and immediately after LASIK in mesopic condition at the refractive eye center, Riyadh, Saudi Arabia.
RESULTS
The pupil showed mild dilation immediate after LASIK. Mean pupil size before LASIK was 4.10 ± 0.74 and immediate after was 4.74 ± 0.82, P value <0.0001. No association was found with age, sex, central corneal thickness or pre-operative refractive measurements (CCT).
CONCLUSION
There is a change in pupil size that immerses immediately after LASIK; postulations suggested for pupillary dilation include the effect of suction ring, post-operative steroid eye drops, dark room, pain and anxiety.
目的
探讨准分子原位角膜磨镶术（LASIK）对术后即刻瞳孔大小变化的影响。
方法
在一项前瞻性研究中，使用手持瞳孔计，于沙特阿拉伯利雅得屈光性眼中心，在暗光条件下，对35例连续患者的70只眼在LASIK术前及术后即刻测量瞳孔大小。
结果
LASIK术后即刻瞳孔出现轻度散大。LASIK术前平均瞳孔大小为4.10±0.74，术后即刻为4.74±0.82，P值<0.0001。未发现与年龄、性别、中央角膜厚度或术前屈光测量值（CCT）有关联。
结论
LASIK术后即刻瞳孔大小会发生变化；推测瞳孔散大的原因包括吸引环的作用、术后类固醇眼药水、暗室、疼痛和焦虑。
