目的：报告一种新的技术，用于后房型人工透镜的巩膜内固定，使用硅橡胶微管操作haptics到positive.Methods：巩膜内固定进行了6只眼，并在此回顾性病例系列的结果进行了评估。将外径为0.2 mm的硅胶微管从巩膜切口穿过腔室，并使用30号针进行巩膜切开术。将眼内透镜襻的尖端连接到眼外的硅胶微管。将人工透镜植入后房后，将支撑襻通过其与硅胶微管的连接通过巩膜切口拉出。结果：平均术后矫正视力为最小分辨角的0.62对数（20/43），平均屈光误差为-0.06 ±0.4屈光度，与预期值无显著差异（P= 0.53）。术后并发症包括短暂性低眼压，玻璃体积血，脉络膜detachment.Conclusion：我们的技术使用硅微管减少了眼内手术的数量相比，以前的方法使用镊子或针移动人工透镜触觉从后房到外面通过巩膜切开术。
Purpose:To report a novel technique for intrascleral fixation of a posterior chamber intraocular lens using a silicone microtube to manipulate the haptics into position.Methods:Intrascleral fixation was performed in six eyes and the results evaluated in this retrospective case series. A silicone microtube with a 0.2-mm external diameter was passed from a sclerocorneal incision through the chamber and a sclerotomy made using a 30-gauge needle. The tips of the intraocular lens haptics were connected to the silicone microtube outside the eye. After the intraocular lens was injected into the posterior chamber, the haptics were drawn through the scleral incision through their attachment to the silicone microtube.Results:The mean postoperative corrected visual acuity was 0.62 logarithm of the minimum angle of resolution (20/43) with a mean refraction error of− 0.06±0.4 diopter, which did not differ significantly (P= 0.53) from the expected value. The postoperative complications included transient ocular hypotension, vitreous hemorrhage, and choroidal detachment.Conclusion:Our technique using a silicone microtube reduces the number of intraocular procedures compared with previous methods using forceps or needles for moving the intraocular lens haptics from the posterior chamber to the outside through sclerotomies.
