摘要
目的评估虹模拉钩联合2L型可缝合囊袋张力环(2L-MCTR)治疗各种原因导致的严重晶状体悬韧带异常患者的临床疗效,并对其优缺点、手术技巧和相关并发症进行探讨。方法统计各种原因导致严重晶状体悬韧带异常并发晶状体位置和形态异常的的患者,行可缝合囊袋张力环(2L-MCTR)联合囊袋内人工晶状体植入的患者7例11只眼,术后随访1~3年,检查裸眼视力,娇正视力,眼压、是否有后囊膜混浊。用UBM观察IOL位置、MCTR硬与周围组织的关系。结果11只眼娇正砚力均〉0.3,其中7只眼最佳娇正视力〉0.8,3只眼最佳娇正视力〉0.5。1只眼因外传合并视网膜挫伤,最佳娇正视力为0.3;1只眼改行人工晶状体睫状沟固定术。超声活体显徵镜(UBM)显示MCTR硬人工晶状体位于囊袋内。结论虹膜拉钩的使用可维持术中晶状体囊袋的稳定硬手术过程的操作安全。McTR植入可以使人工晶状体位于囊袋内生理位置,并维持术后人工晶状体的长期稳定性,安全有效地避免患者进行性加重的晶状体悬韧带异常导致的术后人工晶状体脱位。
Objective To evaluate the outcomes of iris hooks and 2 eyelet modified capsular tension ring (2L-MCTR) for treating severe zonular dysfunction of various causes, and explore the advantages and disadvantages,surgical skills and compli cations. Methods The study population comprised 11 eyes (7 patients) with severe zonular compromise that underwent capsu lar bag fixation with 2 eyelet modified capsular tension ring (2L-CTR) and in the bag intraocular lens (IOL) implantation. The postoperative follow up was 1 to 3 years. UCVA(uncorrected visual acuity), BCVA (best corrected visual acuity), IOP (in traocular pressure) and condition of posterior capsule opacification were evaluated. Ultrasound biomicroscopy (UBM) was per formed to observe the positions of IOL,MCTR and the relationship with other anterior segment organizations of eyes. Results Best corrected visual acuity (BCVA)〉0.3 occurred in all of 11 eyes. There were 7 eyes with best corrected visual acuity (BC VA)〉0. 8 and 3 eyes with best corrected visual acuity (BCVA)〉0. 5. BCVA in one eye with retinal contusion was 0. 3. IOL was implanted in the ciliary sulcus in one eye. UBM showed that all the modified capsular tension ring and intraocular lens were in the capsular bag. Conclusions The iris hooks can provide excellent intraoperative capsular stability and secure manipulation during operation. MCTR can ensure the intraocular lens central position in the capsular bag and can maintain its long term sta bility, and it is helpful and effective for avoiding dislocation of the IOL due to progressive weakening of the zonular fibers.
