目的:评估在白内障超声乳化手术时使用适当的手术技巧及相应设备对假性剥脱综合征白内障患者的视力及术中、术后并发症的影响。
方法:回顾性研究。选取53例67眼假性剥脱综合征白内障患者接受超声乳化及人工晶状体植入术。平均年龄71.68±9.96(53~89)岁,其中男性24例(45%),女性29例(55%),包括核性、皮质性及后囊下和成熟期的白内障。
结果:核性白内障较其他类型更为常见(P=0.00)。术前平均最佳矫正视力为0.99±0.30(0.40~1.50)LogMAR,术后平均最佳矫正视力为0.32±0.31(0.00~1.00)LogMAR(P=0.00)。运用虹膜牵拉器12眼(18%)。囊袋张力环植入15眼(22%),其中按计划植入8眼(12%),未计划7眼(10%)。后囊破裂4眼(6%),其中玻璃体脱出2眼(3%),并接受前段玻璃体切割术; 且由于后囊破裂较大,此2眼(3%)转为白内障囊外摘除术。持续性角膜水肿4眼(6%),前房反应5眼(7%)。人工晶体脱位4眼(6%),仅1眼(1.5%)需复位。后囊混浊并接受Nd:YAG激光后囊切开术13眼(20%)。
结论:假性剥脱综合征白内障患者术后视力良好,但术中及术后可能出现的并发症包括后囊破裂,玻璃体脱出,转为白内障囊外摘除术,持续性角膜水肿,前房反应及人工晶状体脱位。为避免并发症的发生,适当的手术技巧和相应设备的使用在手术时是必不可少的。

AIM: To evaluate the visual outcomes and intraoperative and postoperative complications of phacoemulsification surgery in patients with cataract and pseudoexfoliation syndrome(PEX)and the usage of proper surgical techniques and appropriate devices intraoperatively.
METHODS: Sixty-seven eyes of 53 patients with PEX and cataract who had undergone phacoemulsification and intraocular lens(IOL)implantation surgery were evaluated retrospectively. The mean age was 71.68±9.96(53-89)y, and there were 24(45%)males and 29(55%)females. Nuclear, cortical, posterior subcapsular, and mature cataracts were all represented.
RESULTS: Nuclear cataract was significantly more common than other types(P=0.00). The mean preoperative best corrected visual acuity(BCVA)was 0.99±0.30(SD)(0.40-1.50)logMAR, and the mean postoperative BCVA was 0.32±0.31(SD)(0.00-1.00)logMAR(P=0.00). Iris retractors were used in 12(18%)eyes. Capsular tension ring(CTR)implantation was used in 15(22%)eyes, it was planned in 8(12%)and unplanned in 7(10%). Posterior capsule rupture occurred in 4(6%)eyes, and vitreous loss occurred in 2(3%)eyes. Anterior vitrectomy was performed in these 2 eyes. Conversion to extracapsular cataract extraction(ECCE)was needed in these 2(3%)eyes due to large posterior capsular rupture. Persistent corneal edema was observed in 4(6%)eyes, and anterior chamber reaction in 5(7%)eyes. IOL dislocation occurred in 4(6%)eyes, but repositioning was only needed in 1(1.5%)eye. Posterior capsule opacification(PCO)requiring Nd:YAG laser capsulotomy developed in 13(20%)eyes.
CONCLUSION: Postoperative visual acuities of patients with cataract and PEX are satisfactory. However, intraoperative and postoperative complications like posterior capsule rupture, vitreous loss, conversion to ECCE, persistent corneal edema, anterior chamber reaction and IOL dislocation may be observed. To avoid these complications, proper surgical techniques and the use of appropriate devices intraoperatively are essential.
