Helmholtz suspected there was a connection between intraocuclar pressure and lateration of corneal curvature. With a view to potential changes in corneal stability following different refractive procedures, we tried to demonstrate these side effects by increasing the intraocular pressure. A tilting-table was used to induce a rapid pressure increase via the fluid shift. Corneal curvature was measured by photokeratoscopy before and after pressure changes. The results were different in corneas subjected to radial and photorefractive keratotomy than in intact corneas. We suggest a physical model that might provide an explanation.
亥姆霍兹怀疑眼内压与角膜曲率的偏斜之间存在关联。鉴于不同屈光手术后角膜稳定性的潜在变化，我们试图通过增加眼内压来证明这些副作用。使用倾斜台通过液体转移诱导快速的压力升高。在压力变化前后通过光角膜镜测量角膜曲率。接受放射状角膜切开术和光性屈光性角膜切削术的角膜与完整角膜的结果不同。我们提出了一个可能提供解释的物理模型。
