To assess the incidence of cartridge cracks during foldable intraocular lens (IOL) insertion and to determine factors that play a role in the development of these cracks.
Leesburg Regional Ambulatory Surgical Care Center, Leesburg, Florida, USA.
Small incision cataract surgery was performed in 350 consecutive cases. A foldable silicone IOL (Allergan Medical Optics SI-40) was inserted in all cases using the Unfolder cartridge and 3 viscoelastic agents: sodium hyaluronate (Healon, Vitrax) and sodium chondroitin sulfate-sodium hyaluronate (Viscoat).
Cartridge cracks occurred in 52 eyes (14.86%). Almost all cracks (98.1%) occurred in cases in which Healon was used to load the IOL. In each case of a cracked cartridge, there was evidence of the plunger overriding the optic edge.
We recommend the use of chondroitin-based viscoelastic agents to load the SI-40 foldable IOL to minimize the risk of cartridge cracks. Modifications in the design of the IOL inserter may eliminate the problem of cartridge cracks.
评估折叠式人工晶状体（IOL）植入过程中卡盒破裂的发生率，并确定导致这些破裂发生的因素。
美国佛罗里达州利斯堡的利斯堡地区门诊手术护理中心。
连续350例患者接受小切口白内障手术。所有病例均使用Unfolder卡盒及3种粘弹性剂：透明质酸钠（Healon、Vitrax）和硫酸软骨素钠-透明质酸钠（Viscoat）植入折叠式硅胶IOL（爱尔康医疗光学SI-40）。
52只眼（14.86%）出现卡盒破裂。几乎所有破裂（98.1%）发生在使用Healon装载IOL的病例中。在每个卡盒破裂的病例中，均有推注器越过光学边缘的证据。
我们建议使用基于软骨素的粘弹性剂来装载SI-40折叠式IOL，以将卡盒破裂的风险降至最低。IOL植入器设计的改进可能会消除卡盒破裂的问题。
