The aim of this study was to report a technique for the removal of dislocated polymethyl methacrylate (PMMA) intraocular lenses (IOLs) in glaucomatous eyes.
Dislocated PMMA IOLs were removed from the inferior sclerocorneal incision, and sutureless intrascleral fixation of each IOL was performed to preserve the intact superior conjunctiva and sclera for future trabeculectomy or to maintain a functional filtering bleb of trabeculectomy.
In two cases, the condition of the bleb did not change, while the intraocular pressure improved or did not change after the procedures. IOL fixation was stable with no complications, such as tilt, decentration, or extrication of the IOL haptics.
This procedure of preserving the superior conjunctiva and sclera can maintain the function of the bleb, superior cornea and sclera and may contribute to the success of future trabeculectomy.
本研究的目的是报告一种在青光眼眼中取出脱位的聚甲基丙烯酸甲酯（PMMA）人工晶状体（IOL）的技术。
通过下方巩膜角膜切口取出脱位的PMMA人工晶状体，并对每个人工晶状体进行无缝线巩膜内固定，以保留完整的上方结膜和巩膜，以备将来进行小梁切除术或维持小梁切除术功能性滤过泡。
在两例病例中，滤过泡情况未改变，而术后眼压改善或未改变。人工晶状体固定稳定，无人工晶状体襻倾斜、偏心或脱出等并发症。
这种保留上方结膜和巩膜的手术方法可维持滤过泡、上方角膜和巩膜的功能，并可能有助于将来小梁切除术的成功。
