Abstract

Purpose: To assess the advantages offered by the air pump assisted PDEK technique that utilizes pressurized Anterior Chamber (AC) air infusion.

Methods: Pressurized air infusion was provided through an anterior chamber maintainer connected to the fluid air exchange system of a posterior vitrectomy machine during surgery.

Results: Pressurized air infusion within the AC helped perform Descemetorhexis, prevented bleeding during Peripheral Iridectomy (PI) and synechiolysis, prevented oozing of blood from peripheral corneal neovascularization into the AC and thus helped maintain a non-fibrinous AC environment. In addition, it helped in precise graft manipulation, centration, edge unfolding and unwrinkling after it was floated against the stroma as well as faster graft adhesion. It also prevented AC depth fluctuations during intra-cameral maneuvers and prevented intra-operative as well as post-operative graft detachment.

Conclusions: This technique makes several steps of surgery easier and improves graft adhesion.

加压空气输注用于角膜内皮成形术(PDEK) -气泵辅助的PDEK技术。

目的:评估空气泵辅助PDEK技术利用前房加压(AC)空气输注所提供的优势。方法:术中通过前房维持器与后路玻璃体切割机的液体空气交换系统连接，给予加压空气输注。结果:眼角膜内的加压空气输注有助于角膜外周虹膜切除术(Peripheral Iridectomy, PI)和联合溶解术中的出血，防止角膜外周新生血管的血液渗出眼角膜，从而维持眼角膜的非纤维性环境。此外，它有助于精确的移植物操作、集中、边缘展开和在基质上漂浮后的解皱，以及更快的移植物粘附。它还可以防止在摄像机内操作时的交流深度波动，防止术中和术后移植物脱离。结论:该技术简化了手术的几个步骤，并改善了移植物的粘连。
