目的 评价超声乳化白内障摘出人工晶状体植入术 (PHACO +IOL)的疗效。方法 对 10 0例 (112眼 )白内障施行超声乳化人工晶状体植入手术治疗 ,并对术后 1周、1月及 3月视力及散光进行追踪观察。与同期 10 0例 (10 5眼 )白内障囊外摘出后房型人工晶状体植入术 (ECCE +IOL)的病例组比较。结果 PHACO +IOL组术后视力≥ 0 .5者 ,1周占 92 9% ,1月占94 1% ,3月占 96 8% ;术后平均散光 1周为 1 2 0± 0 .82D ,1月为 0 95± 0 70D ,3月为 0 6 9± 0 .70D ;与ECCE组比较 ,术后视力差异性显著 (P <0 .0 5 ) ,术后散光差异性显著 (P <0 .0 1)。结论 超声乳化人工晶状体植入术视力恢复快 ,效果好而稳定 ,角膜散光小。
Objective To evaluate the efficacy of phacoemulsification cataract extraction and intraocular lens implantation (PHACO + IOL). Methods Phacoemulsification and intraocular lens implantation were performed in 100 cases (112 eyes) of cataract. Visual acuity and astigmatism were observed at 1 week, 1 month and 3 months after operation. Compared with the case group of posterior chamber intraocular lens implantation (ECCE + IOL) in 100 cases (105 eyes) of extracapsular cataract. Results The postoperative visual acuity of PHACO + IOL was 92.5% in 1 week, 94.1% in January and 96.8% in March. The average postoperative astigmatism was 120 ± 0.82D, 0 95 ± 0 70D in January and 0 6 9 ± 0. 70D in March. Compared with ECCE group, the postoperative visual acuity was significantly different (P <0.05), and the postoperative astigmatism difference was significant (P <0 .0 1). Conclusion Phacoemulsification and intraocular lens implantation have good visual acuity recovery, good and stable effect and small corneal astigmatism.
