PURPOSE
To compare a biomechanically corrected intraocular pressure (bIOP) algorithm provided by the dynamic Scheimpflug analyzer (Corvis ST) with Goldmann applanation tonometry IOP (Goldmann IOP) and standard dynamic Scheimpflug analyzer IOP measurements before and after laser in situ keratomileusis (LASIK) and refractive lenticule extraction small-incision lenticule extraction (SMILE) surgeries.
SETTING
Smile Eye Clinic, Munich, Germany, and University of Liverpool, Liverpool, United Kingdom.
DESIGN
Retrospective case series.
METHODS
Patients scheduled for LASIK and patients scheduled for small-incision lenticule extraction for myopia or myopic astigmatism were included. The preoperative and postoperative evaluations included Goldmann, Scheimpflug tomography, and dynamic Scheimpflug analyzer IOP measurements.
RESULTS
The study comprised 14 patients in the LASIK group and 22 patients in the small-incision lenticule extraction group. Preoperative Goldmann IOP and Scheimpflug analyzer IOP values showed significant positive correlation with central corneal thickness (CCT) (P = .05 for LASIK; P = .003 for small-incision lenticule extraction). No significant correlation was found between bIOP and CCT (P > .05). After both surgeries, there were significant decreases in Goldmann IOP (-3.2 mm Hg ± 3.4 [SD] and -3.2 ± 2.1 mm Hg, respectively; both P < .001) and Scheimpflug analyzer IOP (-3.7 ± 2.1 mm Hg and -3.3 ± 2.0 mm Hg, respectively, both P < .001) compared with preoperative readings, whereas bIOP did not differ significantly (0.1 ± 2.1 mm Hg and 0.8 ± 1.8 mm Hg, respectively; P = .80 and P = .273, respectively).
CONCLUSIONS
The bIOP readings before and after LASIK and small-incision lenticule extraction were neither significantly different nor correlated with CCT. In contrast, both Goldmann IOP and Scheimpflug analyzer IOP had significant reductions postoperatively and showed significant correlation with CCT preoperatively.
目的
比较眼前节分析仪（Corvis ST）提供的生物力学校正眼压（bIOP）算法与 Goldmann 压平眼压（Goldmann IOP）和标准动态 Scheimpflug 分析仪 IOP 测量值，这些测量值是在 LASIK 和屈光性晶状体切除术（SMILE）手术前后进行的。
地点
德国慕尼黑微笑眼科诊所和英国利物浦大学。
设计
回顾性病例系列。
方法
纳入计划接受 LASIK 手术和计划接受近视或近视散光屈光性晶状体切除术的患者。术前和术后评估包括 Goldmann、Scheimpflug 断层扫描和动态 Scheimpflug 分析仪眼压测量。
结果
该研究包括 LASIK 组的 14 例患者和 SMILE 组的 22 例患者。术前 Goldmann IOP 和 Scheimpflug 分析仪 IOP 值与中央角膜厚度（CCT）呈显著正相关（LASIK 组 P =.05；SMILE 组 P =.003）。bIOP 与 CCT 之间无显著相关性（P >.05）。两种手术后，Goldmann IOP（分别降低-3.2 ± 3.4 [SD] 和-3.2 ± 2.1 mmHg；均 P <.001）和 Scheimpflug 分析仪 IOP（分别降低-3.7 ± 2.1 和-3.3 ± 2.0 mmHg；均 P <.001）均较术前读数显著降低，而 bIOP 无显著差异（分别为 0.1 ± 2.1 和 0.8 ± 1.8 mmHg；P =.80 和 P =.273）。
结论
LASIK 和 SMILE 手术前后的 bIOP 读数既无显著差异，也与 CCT 无相关性。相比之下，Goldmann IOP 和 Scheimpflug 分析仪 IOP 术后均显著降低，术前与 CCT 呈显著相关性。
