METHODS: Twenty-three eyes performed SF-IOL implantation combined with PPV (Group 1), and 34 eyes performed SF-IOL implantation combined with AV (Group 2) were included in the study prospectively. The SF-IOL, either polymethyl methacrylate or foldable IOL, was sutured into the sclera using PC-9 sutures in an irregular, knotless, and zigzag-shaped manner. The scleral tunnel was approximately 12-15 mm long, with at least four sharp edges. Suture tips were trimmed within the scleral tunnel. Postoperative outcomes and complications were evaluated.
RESULTS: Both groups showed no complications such as suture tip expulsion, suture reaction, IOL dislocation, or increased intraocular pressure during postoperative visits. Group 1 exhibited a statistically significant improvement in visual acuity compared to preoperative values (P = 0.036 for the 1st month, <0.001 for the 3rd month). Similarly, Group 2 demonstrated a statistically significant improvement in visual acuity compared to the preoperative period (P = 0.001 for the 1st month, <0.001 for the 3rd month).
CONCLUSIONS: The \"irregular, knotless, and zigzag-shaped scleral tunnel suture technique\" yielded favorable results in terms of IOL stability and visual acuity. This technique can be safely employed in patients undergoing SF-IOL implantation combined with PPV or AV.
方法:23只眼进行SF-IOL植入联合PPV(第1组),前瞻性研究纳入了34只眼进行SF-IOL植入联合房室(第2组)。SF-IOL,聚甲基丙烯酸甲酯或可折叠IOL,使用PC-9缝合线缝合到巩膜中,无结,和锯齿形的方式。巩膜隧道长约12-15毫米,至少有四个锋利的边缘。在巩膜隧道内修剪缝合尖端。评估术后结果和并发症。
结果:两组均未出现缝线尖端脱落等并发症,缝合反应,人工晶状体脱位,或术后就诊时眼内压升高。与术前相比,第1组的视力显着改善(第1个月P=0.036,第3个月<0.001)。同样,与术前相比,第2组的视力有统计学上的显着改善(第1个月的P=0.001,第3个月<0.001)。
结论:“不规则,无结,锯齿形巩膜隧道缝合技术在IOL稳定性和视力方面取得了良好的效果。该技术可以安全地用于接受SF-IOL植入联合PPV或AV的患者。
