To determine the variation in strength of clear corneal incisions, as demonstrated by degree of incision leakage when challenged by increased intraocular pressure, in relationship to the incision width and length.
Mackool Eye Institute, Astoria, New York.
Clear corneal incisions 3.0 or 3.5 mm in width and from 1.0 to 3.5 mm in length (0.5 mm increments) were studied in human cadaver whole globes. Pressure was applied at the corneal apex or 8.0 mm posterior to the external wound margin to determine the strength of the incision with the application of external force.
Clear corneal incisions of 3.0 or 3.5 mm in width and at least 2.0 mm in length demonstrated substantially greater resistance to incision failure than shorter incision lengths with both apical and posterior applied forces.
Clear corneal incisions 2.0 mm or greater in length demonstrate resistance to leakage comparable to similarly constructed scleral tunnel incisions.
通过在眼内压升高时切口渗漏程度来确定透明角膜切口的强度变化，研究其与切口宽度和长度的关系。
纽约阿斯托里亚的麦库尔眼科研究所。
在人类尸体全眼球上研究宽度为3.0或3.5毫米、长度为1.0至3.5毫米（以0.5毫米递增）的透明角膜切口。在角膜顶点或距外部伤口边缘后方8.0毫米处施加压力，以通过施加外力来确定切口的强度。
宽度为3.0或3.5毫米且长度至少为2.0毫米的透明角膜切口，在顶点和后方施加力时，比更短长度的切口对切口失败表现出显著更大的抵抗力。
长度为2.0毫米或更长的透明角膜切口对渗漏的抵抗力与类似构造的巩膜隧道切口相当。
