Abstract

Purpose: To define and evaluate the short-term clinical outcomes of the four-flanged technique for scleral fixation of a dislocated four-eyelet intraocular lens (IOL).Methods: Eleven eyes of 11 patients who underwent scleral fixation of dislocated four-eyelet intraocular lenses using a four-flanged technique were studied retrospectively. We measured the best-corrected visual acuity (BCVA), corneal endothelial cell density, intraocular pressure (IOP), spherical equivalent, astigmatism, IOL tilt and decentration, and postoperative complications.Results: The BCVA was 0.25 ± 0.11 logarithm of the minimal angle of resolution (logMAR) before surgery and 0.14 ± 0.12 logMAR 6 months later (p < 0.001). The corneal endothelial cell count was 2,427 ± 384 and 2,367 ± 298/mm2 before and after surgery, respectively (p = 0.285). The spherical equivalent was 6.02 ± 4.90 and 0.11 ± 0.36 before and after surgery, respectively. There was no significant difference in astigmatism before and after surgery. The mean IOL tilt and decentration were 2.44 ± 1.68° and 0.23 ± 0.09 mm, respectively. The refractive difference was 0.11 ± 0.24 diopters (D). Postoperative complications occurred in one eye; one flange lay outside the scleral tunnel, triggering hyperemia and conjunctival inflammation.Conclusions: The four-flanged scleral fixation technique for a dislocated four-eyelet IOL improved the BCVA but did not significantly affect corneal endothelial cell loss. The procedure significantly reduced postoperative IOL tilt, decentration, and astigmatism, and may be a useful alternative to scleral fixation of a dislocated four-eyelet IOL.
四法兰技术治疗脱位四眼人工晶状体巩膜固定
目的:探讨四翼缘巩膜固定脱位四眼人工晶状体的近期临床效果。方法:对11例采用四翼缘巩膜固定脱位四孔人工晶状体患者11只眼进行回顾性研究。我们测量了最佳矫正视力(BCVA)、角膜内皮细胞密度、眼内压(IOP)、球体当量、散光、IOL倾斜和脱位以及术后并发症。结果:BCVA术前为最小分辨角(logMAR)的0.25±0.11对数,6个月后为0.14±0.12对数(<i>p</i>& lt;0.001)。角膜内皮细胞计数分别为2,427±384个和2,367±298个/mm;术前、术后分别(<i>p</i>= 0.285)。术前和术后的球等效度分别为6.02±4.90和0.11±0.36。手术前后散光无明显差异。人工晶状体平均倾斜2.44±1.68°,离体0.23±0.09 mm。屈光差为0.11±0.24屈光度(D)。术后1眼出现并发症;一个法兰位于巩膜隧道外,引起充血和结膜炎症。结论:四翼巩膜固定技术用于脱位的四眼人工晶状体可改善BCVA,但对角膜内皮细胞损失无显著影响。该手术可显著降低术后人工晶状体倾斜、脱位和散光,可能是脱位四眼人工晶状体巩膜固定的有效替代方法。
