摘　　要：目的探讨近视患者准分子激光原位角膜磨镶术(1aser in stiu keratomileusis,LASIK)术后近距离工作疲劳症状及正/负相对调节的变化,并分析正/负相对调节对术后近距离工作疲劳症状的影响。方法选择行LASIK手术的32例患者,测定术前、术后1个月时的近距离工作疲劳症状评分、正相对调节和负相对调节,并进行统计学分析。结果⑴近距离工作视疲劳症状评分在术后1个月稍降低,但与术前相比差异无统计学意义(P>0.05)。⑵正相对调节在术后1mo时比术前高(P<0.05),负相对调节在术后1个月与术前相比差异无统计学意义(P>0.05)。结论 LASIK术对调节功能不会造成不利影响,术后随着时间推移,调节力的恢复,近距离工作视疲劳症状也会逐渐缓解。Objective To investigate the changes of positive and negative relative accommodation and symptoms of asthenopia after laser in situ keratomileusis(LASIK) in myopia. And analyze the effects of positive and negative relative accommodation on asthenopia. Methods A total of 32 myopia patients accepted LASIK. The myopia patients were measured at the time before surgery and 1 month after surgery. Questionnaire was used to evaluate the symptoms of asthenopia. Results ⑴ The symptoms of asthenopia reduced a little at 1 month after operation,but there was no significant difference Compared the preoperative symptoms(P>0.05). ⑵PRA at 1 months postoperative was higher than that of preoperative(P<0.05),and there was no significant difference of NRA before and after operation(P>0.05). Conclusion LASIK may have no undesirable influence on accommodative function. With the passage of time,recovers in accommodative force,the symptoms of asthenopia will gradually ease.
