To compare intraocular pressure (IOP) measurement by ORA-IOPcc and Corvis-bIOP after femtosecond laser-assisted LASIK (FS-LASIK).
In this prospective cohort study, 56 eyes from 56 consecutive patients scheduled for FS-LASIK were enrolled. All patients had IOP measurement with ORA and Corvis ST by two blinded independent expert examiners. IOP examinations were conducted between 8 and 11 A.M. Data were collected at baseline and 3 months after FS-LASIK.
The mean age of the participants was 29.1 ± 6.3 years, and 42 (75%) were female. The average of central corneal thickness (CCT) decreased from 537 ± 23 µm at baseline to 458 ± 31 µm after FS-LASIK. The mean postoperative change of IOP was 0.0 ± 2.1 for bIOP and -2.5 ± 3.2 mmHg for IOPcc. The corresponding 95% limits of agreement (LoA) was -4.1 to 4.1 mmHg and -3.8 to 8.8 mmHg, respectively. Both methods showed no significant correlation between ∆IOP and ∆CCT. The 95% LoA between bIOP and IOPcc after FS-LASIK was -4.8 to 9.1 mmHg.
Compared to the ORA-IOPcc, the Corvis-bIOP showed less variation after FS-LASIK and might be a more appropriate choice for measuring IOP in this condition. The agreement of bIOP vs. IOPcc after FS-LASIK is below the clinically acceptable level, and the two methods could not be regarded as interchangeable.
比较飞秒激光制瓣准分子原位角膜磨镶术（FS-LASIK）后通过ORA-IOPcc和Corvis-bIOP测量眼内压（IOP）的情况。
在这项前瞻性队列研究中，纳入了56例计划接受FS-LASIK的连续患者的56只眼。所有患者均由两名独立的盲法专家检查者使用ORA和Corvis ST测量IOP。IOP检查在上午8点至11点之间进行。在基线和FS-LASIK术后3个月收集数据。
参与者的平均年龄为29.1±6.3岁，其中42例（75%）为女性。中央角膜厚度（CCT）的平均值从基线时的537±23μm降至FS-LASIK术后的458±31μm。bIOP的术后IOP平均变化为0.0±2.1，IOPcc为-2.5±3.2mmHg。相应的95%一致性界限（LoA）分别为-4.1至4.1mmHg和-3.8至8.8mmHg。两种方法均显示∆IOP与∆CCT之间无显著相关性。FS-LASIK术后bIOP与IOPcc之间的95%LoA为-4.8至9.1mmHg。
与ORA-IOPcc相比，Corvis-bIOP在FS-LASIK术后的变化较小，可能是在这种情况下测量IOP的更合适选择。FS-LASIK术后bIOP与IOPcc的一致性低于临床可接受水平，这两种方法不能视为可互换的。
