Background

The aim of this study was to assess the validity of rebound tonometry measurements obtained over eyes wearing extended-wear bandage contact lenses with the highest oxygen transmissibility (Dk/t) value of 175 @ -3.00 D.

Methods

A total of 151 normal eyes were included in this prospective pretest-posttest study. A rebound tonometer (iCare PRO) was used to collect intraocular pressure readings from “naked” eyes (eyes without contact lenses) and the same eyes wearing extended-wear lotrafilcon A bandage contact lenses (Alcon Air Optix Night & Day Aqua Contact Lenses). The mean pre- and post-application values were pooled and compared using the paired t-test.

Results

The application of extended-wear lotrafilcon A contact lenses over normal eyes did not cause a statistically significant change in the intraocular pressure measurements obtained using an iCare PRO tonometer (13.74 ± 2.15 mm Hg vs. 13.77 ± 2.26 mm Hg, p-value = 0.6506).

Conclusion

Based on this study conducted on normal eyes, the removal of extended-wear bandage contact lenses is not necessary when taking intraocular pressure measurements using the iCare PRO rebound tonometer.

长戴绷带隐形眼镜的回弹眼压测量。

背景

本研究的目的是评估在佩戴具有最高透氧率 (Dk/t) 值为 175 @ -3.00 D 的长戴绷带隐形眼镜的眼睛上获得的回弹眼压测量的有效性。

方法

该前瞻性前测-后测研究共包括 151 只正常眼。使用回弹眼压计 (iCare PRO) 收集“裸眼”（没有隐形眼镜的眼睛）和佩戴长戴型 Lotrafilcon A 绷带隐形眼镜（Alcon Air Optix Night & Day Aqua 隐形眼镜）的同一只眼睛的眼压读数。使用配对t检验合并和比较平均应用前和应用后值。

结果

使用 iCare PRO 眼压计（13.74 ± 2.15 mm Hg 与 13.77 ± 2.26 mm Hg，p 值 = 0.6506 ）。

结论

根据对正常眼睛进行的这项研究，使用 iCare PRO 回弹眼压计进行眼压测量时，无需取下长戴型绷带隐形眼镜。
