摘要 目的 分析准分子激光原位角膜磨削术(LASIK)后非接触式眼压(NCT)的改变及其相关因素。方法 对术前屈光度为-375~-2450D的患者82例146眼行LASIK治疗,观察6个月以上。手术前后予以NCT等检查,比较术前术后NCT的改变及其相关因素。结果 术前NCT平均值:(1677±271)mmHg。术后:(1376±263)mmHg。差异有显著性。相关系数分别为039,028。结论 LASIK后NCT读数值下降,下降值与实矫屈光度和角膜曲率改变值有相关性,判断眼压时要将读数下降值作为修正值附加上去。 ObjectiveTo assess the changes and relative factors of noncontact tonometer(NCT) after laser in situ keratomileusis (LASIK).MethodsThe database of patients who had LASIK was retrospectively reviewed.Preoperative and postoperative intraocular pressures(IOPs) were measured in 146 eyes (82 patients).The correlation between decrease in IOP and various preoperative and intraoperative parameters was evaluated by regression analysis.ResultsIOP measured with NCT was reduced at the postoperative stage ( u =9 63, P <0 01) The mean IOP reduction after LASIK was (6.02±3.61)mmHg,and the normal range of IOP reduction after LASIK is 0~11 59*!mmHg.There was correlation between decrease in IOP by NCT and actual refraction changes or between decrease in IOP and curvature changes.Regression equation for NCT drop (mmHg)=0 30*!A+2 93[A=actual refraction change(D)].ConclusionIOP measured with NCT was reduced at the postoperative stage after LASIK.It was related to the corneal changes.We should take care about it to prevent or control corticosteroid induced glaucoma and/or ocular hypertension at the postoperative stage after LASIK.It also may be important in the management of any future glaucoma.
