白内障超声乳化摘除联合后房型人工晶体植入术的临床观察

Clinical Observation of Cataract Extraction by Phacoemulsification and Posterior Chamber IOL Implantation

目的 评价PEA +PC -IOL植入术临床效果。方法 对 94眼白内障行超声乳化摘除 ,植入PMMA硬性或Hydrogel折叠式人工晶体。结果 术后 1周、1个月、3个月、6～ 12个月、12～ 18个月、18～ 2 4个月的裸眼视力≥ 0 5者分别为 83 2 %、94 1%、95 9%、93 2 %、92 3%、89 5 %。 3 2mm切口组术后 1周、1个月、3个月、6～ 12个月、18～ 2 4个月的角膜散光与术前比较无统计学差异 (P >0 0 5 ) ;5 5～ 6 0mm切口组术后 1周的散光较术前增加 0 32D(P < 0 5 ) ,术后 1个月以后散光与术前比无统计学差异 (P >0 0 5 ) ,术后 6～ 2 4个月有 10只眼发生后囊混浊 ,导致术后视力下降。结论 PEA +PC -IOL植入术手术时间短 ,病人无痛苦 ,术后视力提高快 ,散光小。后囊混浊是术后最常见的并发症 。

Objective To assess the clinical effects of cataract extraction by phacoemulsification and posterior chamber IOL implantation (PEA+PC-IOL). Methods 94 cases of such patients were performed with PEA+PC-IOL with implantation of PMMA or Hydrogel. Results The naked vision ≥0.5 were 83.2% , 94.1%, 95.9% , 93.2% , 92.3% ,and 89.5% separately postoperation 1 week, 1 m, 3 m, 6-12 m,12-18m and 18-24 m. The corneal astigmatism in 3.2mm group had no significant difference postoperation 1 week, 1 m, 3 m, 6-12 m, 12-18m and 18-24 m (p>0.05). The corneal astigmatism in 5.5-6.0mm group was increased 0.32D in 1 week (p<0.05) and no difference in 1 m. There were 10 eyes with vision decrease 2～24 m after operation due to posterior chamber confusion. Conclusion: PEA+PC-IOL operation might be short, painless, vision improved fast with less astigmatism. The confused posterior chamber was common complication and was the reason to cause vision decrease in long term.
