To evaluate a single surgeon's experience with an automated preloaded intraocular lens (IOL) delivery system and a nonpreloaded system.
This was a prospective, observational case series. Phacoemulsification was performed under topical anesthesia by creating a temporal clear corneal incision. Patients were consecutively assigned to either the Clareon group (n = 50; the IOL was injected into the capsular bag by using an automated injector system) or the AcrySof group (n = 50; the IOL was injected into the capsular bag by using a conventional injector system). The main outcome measures were ease of implantation, intraoperative complications, postoperative centration, and visual acuity.
Additional manipulation in the anterior chamber was not required in 38 (74%) eyes in the Clareon group and 41 (82%) eyes in the AcrySof group. However, seven eyes in the Clareon group and one eye in the AcrySof group required trailing haptic dislodgement from the optic. Furthermore, two eyes in the Clareon group and five eyes in the AcrySof group required injector rotation (varying from 10° to 90°) in the wound. Moreover, in two eyes of the Clareon group, the silicon plunger of the injector system crossed over the optic. None of the patients developed iris trauma and PCR during IOL manipulation. All the IOLs were centered in the capsular bag.
The automated IOL delivery system enables the controlled delivery of an IOL in the capsular bag. The effect of carbon footprints created by plastic generated from the delivery system and the implications of the CO cylinder on the environment should be addressed.
评估一位外科医生使用自动预装人工晶状体（IOL）输送系统和非预装系统的经验。
这是一项前瞻性、观察性的病例系列研究。在表面麻醉下通过颞侧透明角膜切口行超声乳化术。患者连续分为 Clareon 组（n=50；使用自动注射器系统将 IOL 注入囊袋）或 AcrySof 组（n=50；使用传统注射器系统将 IOL 注入囊袋）。主要观察指标为植入的难易程度、术中并发症、术后中心定位和视力。
在 Clareon 组的 38 只（74%）眼中和 AcrySof 组的 41 只（82%）眼中不需要在前房进行额外的操作。然而，Clareon 组的 7 只眼和 AcrySof 组的 1 只眼需要将后襻从光学部上脱离。此外，Clareon 组的 2 只眼和 AcrySof 组的 5 只眼需要在伤口处旋转注射器（从 10°到 90°）。此外，在 Clareon 组的 2 只眼中，注射器系统的硅柱塞越过了光学部。在 IOL 操作过程中，没有患者发生虹膜损伤和 PCR。所有的 IOL 都位于囊袋内。
自动 IOL 输送系统能够在囊袋内控制输送 IOL。应该解决输送系统产生的塑料碳足迹以及 CO 钢瓶对环境的影响问题。
