A 29-gauge model test fine needle is used to create a beveled intrascleral tunnel; with microforceps, a 6-0 polypropylene suture is placed in the bore of the needle, which is used as a guide to pass and externalize the monofilament through the sclera. This maneuver is repeated by passing the suture ends through the intraocular lens (IOL) eyelets. The folded IOL is inserted and centered, the sutures are cut, and the flanges are created by thermocautery and inserted into the scleral tunnel. This technique was performed on 7 patients and visual acuity was recorded. The 4-flanged technique for scleral fixation using a 4-eyelet IOL was an effective and a safe treatment in the setting of aphakia.
采用 29 号模型试验细针制作斜向巩膜隧道;用微型镊子将 6-0 聚丙烯缝线置于针管内,作为引导将单丝穿过巩膜并引出。通过将缝线末端穿过人工晶状体(IOL)眼孔重复此操作。插入并居中折叠的 IOL,剪断缝线,通过热烙法制作翼并插入巩膜隧道。该技术在 7 名患者中进行,并记录了视力。对于无晶状体眼,使用四孔 IOL 的四翼巩膜固定技术是一种有效且安全的治疗方法。
