Purpose

To examine the influence of short-term fenestrated scleral lens wear on intraocular pressure (IOP) in healthy eyes.

Methods

IOP was measured before, during, and after a brief period (1–2 min) of fenestrated, scleral lens wear, using a rebound tonometer, in fifty, young healthy adults (mean age 23 ± 4 years) with normal corneas.

Results

Immediately following lens insertion, 48 of the 50 (96 %) of participants displayed an increase in IOP (mean ± SD increase in these participants of 3.8 ± 2.0 mmHg). Immediately following lens removal, 50 % of participants displayed a reduction in IOP, equal to or lower than, the pre-insertion IOP (-1.0 ± 0.8 mmHg lower than baseline). The remaining 50 % of participants displayed an IOP slightly greater than the pre-insertion IOP (1.6 ± 1.0 mmHg greater) after lens removal.

Conclusions

Short-term fenestrated scleral lens wear resulted in a small, but statistically significant, increase in IOP in 96 % of young healthy participants (< 4 mmHg on average), which decreased to a level similar to pre-lens insertion IOP levels immediately following lens removal. Further research is required to determine if this measured change in IOP during scleral lens wear is artefactual, or an elevation in the true IOP.

短期佩戴有孔巩膜镜对眼压的影响。

目的

研究短期佩戴有孔巩膜镜对健康眼内眼压 (IOP) 的影响。

方法

使用回弹眼压计在 50 名角膜正常的年轻健康成年人（平均年龄 23 ± 4 岁）佩戴有孔巩膜镜片之前、之中和之后（1-2 分钟）测量眼压。

结果

立即插入镜片后，50 名参与者中的 48 人 (96%) 表现出 IOP 增加（这些参与者的平均 ± SD 增加 3.8 ± 2.0 mmHg）。摘除镜片后，50% 的参与者立即表现出眼压降低，等于或低于插入前的眼压（比基线低 -1.0 ± 0.8 mmHg）。其余 50% 的参与者在摘除镜片后表现出的 IOP 略高于插入前的 IOP（高 1.6 ± 1.0 mmHg）。

结论

短期佩戴有孔巩膜镜导致 96% 的年轻健康参与者的眼压略有增加，但具有统计学意义（平均 < 4 mmHg），其降低到与镜片插入前的眼压水平相似的水平。移动。需要进一步的研究来确定在巩膜镜片佩戴期间这种测量的 IOP 变化是人为的，还是真实 IOP 的升高。
