To report a technique for performing sutureless intrascleral fixation of a posterior chamber intraocular lens (PC-IOL) and analyzing the clinical outcomes and postoperative complications. . 68 eyes of 66 patients who received the technique were studied retrospectively.
The best-corrected visual acuity (BCVA), intraocular pressure (IOP), anterior chamber depth (ACD), IOL tilt and decentration, corneal topography (1 and 2), and postoperative complications were determined at 3 months.
The mean preoperative BCVA was 1.63 ± 1.24 logMAR units, and the mean postoperative BCVA was 0.74 ± 0.59 logMAR units at 3 months ( < 0.05). The mean preoperative IOP was 21.9 ± 12.6 mmHg, and the mean postoperative IOP was 16.9 ± 4.5 mmHg at 3 months ( = 0.001). The mean preoperative corneal topography (K1 and K2) was 1 = 42.14 ± 1.91 and 2 = 43.54 ± 1.51; the mean postoperative corneal topography (1 and 2) was 1 = 43.03 ± 2.18 and 2 = 43.40 ± 1.71 at 3 months ( = 0.678 and 0.468, respectively). The mean preoperative spherical equivalent was +11.00 ± 13.19 diopters (), and the mean postoperative spherical equivalent was +0.06 ± 0.86 ( < 0.005). The mean IOL tilt was 2.4 ± 1.7°, and the mean decentration was 0.35 ± 0.21 mm. The mean ACD was 4.31 ± 0.29 mm.
The 27-gauge sutureless intrascleral PC-IOL implantation technique minimizes intraoperative injury, simplifies procedure, and provides good PC-IOL fixation with few postoperative complications.
报告一种用于后房型人工晶状体(PC-IOL)无缝线巩膜内固定的技术,并分析其临床结果和术后并发症。对接受该技术的66例患者的68只眼进行回顾性研究。
在术后3个月时测定最佳矫正视力(BCVA)、眼压(IOP)、前房深度(ACD)、人工晶状体倾斜和偏心、角膜地形图(K1和K2)以及术后并发症。
术前平均BCVA为1.63±1.24 logMAR单位,术后3个月时平均BCVA为0.74±0.59 logMAR单位(P<0.05)。术前平均眼压为21.9±12.6 mmHg,术后3个月时平均眼压为16.9±4.5 mmHg(P=0.001)。术前平均角膜地形图(K1和K2)为K1 = 42.14±1.91和K2 = 43.54±1.51;术后3个月时平均角膜地形图(K1和K2)为K1 = 43.03±2.18和K2 = 43.40±1.71(P分别为0.678和0.468)。术前平均球镜当量为+11.00±13.19屈光度(D),术后平均球镜当量为+0.06±0.86 D(P<0.005)。人工晶状体平均倾斜度为2.4±1.7°,平均偏心度为0.35±0.21 mm。平均前房深度为4.31±0.29 mm。
27G无缝线巩膜内PC-IOL植入技术可将术中损伤降至最低,简化手术过程,并能良好地固定PC-IOL,术后并发症较少。
