We describe the essential steps in the successful phacoemulsification of the rock-hard, dense cataract. Appropriate and directed preoperative history, physical examination, and diagnostics allow the surgeon to select the best incision, anesthesia, and intended surgical technique for a given dense nuclear challenge. Hard nucleus-specific approaches for hydrodissection, pupil management, and zonular protection then allow the surgeon to approach the rock-hard nucleus with maximum safety. Dense nuclear dismantling options are then discussed in detail along with fluidic and power modulation considerations. Various specific phacoemusification machine settings for rock-hard cataracts from the authors representing several different phaco systems are then presented. The combination of these steps and considerations allow a more successful dense cataract removal and potential restoration of vision for patients. This paper represents the collective experience and advice of the Challenging and Complex Cataract Surgery Subcommittee.
我们描述了成功乳化坚硬、致密白内障的关键步骤。适当且有针对性的术前病史、体格检查和诊断可使外科医生为特定的核硬化挑战选择最佳的切口、麻醉和预期手术技术。针对硬核的水分离、瞳孔管理和悬韧带保护的特定方法可使外科医生以最大安全性处理坚硬的核。然后详细讨论致密核的拆解选项,并考虑流体动力学和功率调节。随后介绍了几位不同的超声乳化仪作者针对坚硬白内障的各种特定超声乳化仪设置。这些步骤和注意事项的结合可使致密白内障的清除更成功,并有可能为患者恢复视力。本文代表了挑战性和复杂性白内障手术小组委员会的集体经验和建议。
