This study reports the clinical results of sutureless intrascleral fixation of posterior chamber intraocular lenses (PC IOLs) in eyes without capsular support.
Thirty patients without capsular support who underwent standard 3-piece foldable PC IOL implantation using the sutureless intrascleral fixation technique were studied retrospectively. Folded PC IOLs were injected through corneal incisions, with 2 haptics piercing out from 2 corresponding scleral punctures, which were 1.5 mm from the limbus and exactly 180° to each other, and then 2 haptics piercing respectively were placed in 2 corresponding limbus-parallel intrascleral tunnels. All patients were evaluated for preoperative and postoperative status and complications.
During the follow-up period, the visual acuity of all 30 patients significantly improved, with that of 21 patients improving by more than 0.6. The intraocular pressures of all patients were stable. All PC IOLs were stable and centered. Optical coherence tomography revealed that the haptics were located within the tunnel. Other complications, such as IOL dislocation, endophthalmitis, and retinal detachment, were not detected.
Sutureless intrascleral fixation is safe and effective for the implantation of PC IOLs in eyes without capsular support from a variety of causes.
本研究报告无晶状体囊支持眼行后房型人工晶状体（PC IOL）无缝线巩膜内固定术的临床结果。
回顾性研究30例无晶状体囊支持且采用无缝线巩膜内固定技术行标准三件式可折叠PC IOL植入术的患者。折叠式PC IOL通过角膜切口注入，2个袢从距角膜缘1.5 mm且相互呈180°的2个相应巩膜穿刺孔穿出，然后将分别穿出的2个袢置于2个相应的平行于角膜缘的巩膜隧道内。对所有患者的术前、术后情况及并发症进行评估。
随访期间，30例患者视力均显著提高，其中21例患者视力提高超过0.6。所有患者眼压稳定。所有PC IOL均稳定且居中。光学相干断层扫描显示袢位于隧道内。未发现人工晶状体脱位、眼内炎和视网膜脱离等其他并发症。
无缝线巩膜内固定术对于因各种原因无晶状体囊支持眼植入PC IOL是安全有效的。
