Abstract

Purpose: The influence of central corneal thickness (CCT) on intraocular pressure (IOP) measurement by Diaton is debatable. We present a correlation of CCT to transpalpebral IOP (tpIOP) and its determinants in patients undergoing transepithelial photorefractive keratectomy (TPRK) in Saudi Arabia.

Methods: In this cross-sectional study held in 2022, the IOP of patients undergoing TPRK was measured by Diaton tonometer. The CCT was measured before and 1 week after refractive surgery. The correlation coefficient of CCT and IOP and its Pearson P value were estimated. The effects of gender, type of refractive error (RE), and corneal epithelial thickness (CET) on the correlation of IOP to CCT were reviewed.

Results: We studied 202 eyes in 101 patients (Male: Female, 47:53; age 25.7 ± 5.8 years). The tpIOP was 15.1 ± 2.8 mmHg before, 15.9 ± 2.8 mmHg 1 week after, and 15.7 ± 4.1 mmHg 1 month after TPRK. The CCT was significantly correlated with tpIOP before surgery (Pearson correlation 0.168, P = 0.017) and after tPRK (Pearson correlation 0.246, P < 0.001). Gender (P = 0.96), CET (P = 0.43), and type of RE (P = 0.99) were not significant determinants of correlation between CCT and tpIOP before TPRK. The correlation of tpIOP and CCT was not affected by gender (P = 0.07), CET (P = 0.39), and type of RE (P = 0.13).

Conclusion: CCT should be considered before interpreting tpIOP measured by with Diaton. Diaton could be a useful tool to monitor IOP changes in young patients undergoing refractive surgery.

沙特患者经上皮性屈光性角膜切除术前后经眼睑眼压测量及角膜中央厚度的变化。

目的:角膜中央厚度(CCT)对Diaton测量眼压(IOP)的影响尚存争议。我们提出了CCT与沙特阿拉伯接受经上皮光屈光性角膜切除术(TPRK)患者的经睑IOP (tpIOP)及其决定因素的相关性。方法:在2022年进行的横断面研究中，采用Diaton眼压计测量TPRK患者的IOP。在屈光手术前和术后1周测量CCT。估计CCT与IOP的相关系数及其Pearson P值。本文综述了性别、屈光不正类型(RE)和角膜上皮厚度(CET)对IOP与CCT相关性的影响。结果:101例患者202只眼(男:女47:53;年龄(25.7±5.8岁)。tpIOP术前为15.1±2.8 mmHg，术后1周为15.9±2.8 mmHg，术后1个月为15.7±4.1 mmHg。术前CCT与tpIOP (Pearson相关0.168,P = 0.017)、tPRK后CCT与tpIOP (Pearson相关0.246,P < 0.001)显著相关。性别(P = 0.96)、CET (P = 0.43)和RE类型(P = 0.99)不是TPRK前CCT与tpIOP相关性的显著决定因素。tpIOP与CCT的相关性不受性别(P = 0.07)、CET (P = 0.39)、RE类型(P = 0.13)的影响。结论:在解释Diaton测量的tpIOP前应考虑CCT。对于接受屈光手术的年轻患者，Diaton可能是监测IOP变化的有用工具。
