The aim of this study was to evaluate the clinical outcomes of scleral fixation of a posterior chamber intraocular lens and an anterior vitrectomy through sclerotomies, 1 mm posterior to the limbus. The study comprised of seven eyes that required a scleral fixation. Sclerotomies, 1 mm posterior to the limbus, were performed using a 20G sclerotome at the 2 and 8 o'clock positions. Group 1 was defined as four eyes requiring scleral fixation of the secondary IOL (Intraocular lens), and group 2 as three eyes where dislocated IOLs were repositioned and fixed to the sclera via sclerotomy sites. In all the eyes, the knot of string (10-0 prolene, W1713, Ethicon, USA) was buried. Postoperatively, the visual acuity was greatly improved, by more than 4 lines in the Snellen visual acuity chart, with the exception of one case of macular degeneration. The scleral fixation of the IOL through sclerotomies, 1 mm posterior to the limbus, had advantages in that the scleral fixation of the IOL could be achieved through sclerotomy sites, and the anterior vitrectomy parallel to the iris plane.
本研究的目的是评估通过在角膜缘后1毫米处进行巩膜切开术来固定后房型人工晶状体和进行前部玻璃体切除术的临床效果。该研究包括7只需要进行巩膜固定的眼睛。在2点和8点位置使用20G巩膜刀在角膜缘后1毫米处进行巩膜切开术。第1组定义为4只需要巩膜固定二期人工晶状体(眼内晶状体)的眼睛,第2组为3只脱位的人工晶状体通过巩膜切开部位重新定位并固定到巩膜的眼睛。在所有眼睛中,线结(10-0普理灵,W1713,美国强生公司)均被埋入。术后,除1例黄斑变性外,视力均有显著提高,在斯内伦视力表上提高了4行以上。通过在角膜缘后1毫米处进行巩膜切开术来固定人工晶状体具有以下优点:可以通过巩膜切开部位实现人工晶状体的巩膜固定,并且可以平行于虹膜平面进行前部玻璃体切除术。
