We studied 21 consecutive cases of posterior chamber intraocular lens implantation in the absence of an intact lens capsule performed during penetrating keratoplasty. Twenty patients had iris sutures to support the posterior chamber intraocular lenses (one required no suture). Twelve patients had closed-loop anterior chamber intraocular lenses, and five patients had other types of intraocular lenses explanted at the time of surgery. Postoperative follow-up time averaged 10 months, ranging from 2 to 19 months, with ten eyes having at least 1 year follow-up. All 21 grafts remained clear at their latest examinations. Seven eyes (33%) had 20/50 or better visual acuity, nine (43%) had a visual acuity from 20/60 to 20/150, and five (24%) had a visual acuity of 20/200 or worse at their latest examinations. All patients had improved vision postoperatively, and nine eyes (43%) achieved an improvement in vision of five lines or better. Of the ten eyes with at least 1 year follow-up, all had their sutures removed and four (40%) had 20/40 or better visual acuity. Of the remaining six patients (60%) with visual acuity worse than 20/40, all had significant retinal disease and/or glaucoma.
我们研究了21例在穿透性角膜移植术中未完整晶状体囊膜情况下进行后房型人工晶状体植入的连续病例。20例患者有虹膜缝线以支撑后房型人工晶状体（1例无需缝线）。12例患者植入了闭环前房型人工晶状体，5例患者在手术时植入了其他类型的人工晶状体。术后随访时间平均为10个月，范围为2至19个月，其中10只眼至少随访了1年。在最近一次检查时，所有21片植片均保持清晰。7只眼（33%）的视力为20/50或更好，9只眼（43%）的视力在20/60至20/150之间，5只眼（24%）在最近一次检查时的视力为20/200或更差。所有患者术后视力均有改善，9只眼（43%）的视力提高了5行或更多。在至少随访1年的10只眼中，所有患者的缝线均已拆除，4只眼（40%）的视力为20/40或更好。在其余6例（60%）视力低于20/40的患者中，所有患者均患有严重的视网膜疾病和/或青光眼。
