Corneal ulceration leading to perforation can mainly occur after infection, trauma, corneal dryness and exposure keratitis. When corneal ulceration does not respond to medical treatment, a penetrating keratoplasty allows the elimination of infected tissue and antigenic material. It can restore the integrity of the anterior segment of the eye. The tissue taken could serve for bacteriologic research. In spite of the great number of complications the percentage of success is about 50%.
角膜溃疡导致穿孔主要可发生在感染、外伤、角膜干燥及暴露性角膜炎之后。当角膜溃疡经药物治疗无效时，穿透性角膜移植术可清除感染组织和抗原物质。它能恢复眼前段的完整性。所取组织可用于细菌学研究。尽管有大量并发症，但成功率约为50%。
