反眉状及梯形两种巩膜小切口白内障囊外摘除联合IOL植入术的疗效对比

目的:观察反眉状及梯形两种巩膜小切口白内障囊外摘除联合人工晶状体植入术的临床疗效。方法:年龄相关性白内障患者89例113眼随机分为A组(43例56眼)和B组(46例57眼),分别采用反眉状及梯形两种无缝线巩膜小切口白内障囊外摘除联合人工晶状体植入术,术后1wk;1mo及3mo检查BCVA、角膜散光、眼压、人工晶状体位置以及并发症情况。结果:两组术后BCVA均较术前显著提高,差异有统计学意义(P<0.05),但术后角膜散光与术前比较差异无统计学意义;两组术后1wk;1mo及3moBCVA和角膜散光在组内和组间比较差异均无统计学意义。两组术后均未发生眼压异常升高、大泡性角膜病变和化脓性眼内炎等并发症。结论:反眉状及梯形两种无缝线巩膜小切口白内障囊外摘除联合人工晶状体植入术均具有术后视力恢复快、散光小、安全简便、不需要昂贵设备等优点,适合在基层医院推广应用。

Comparison of the efficacy of extracapsular cataract extraction combined with intrao-cular lens implantation by two kinds of converse frown and trapezoidal scleral small incision

AIM:To observe clinical efficacy of extracapsular cataract extraction combined with intraocular lens implantation by two kinds of converse frown and trapezoidal scleral small incision.·METHODS: Eighty-nine patients 113 eyes age-related cataract patients were randomly divided into A group (43 cases, 56 eyes) and B group (46 cases, 57 eyes), they received extracapsular cataract extraction combined with intraocular lens implantation by two kinds of converse frown and trapezoidal scleral small incision respectively, the best-corrected uisual aluity (BCVA), corneal astig-matism, intraocular pressure, intraocular lens position and complications were observed in 1 week, 1 month and 3 months after surgery. ·RESULTS: The postoperative BCVA of both groups was improved significantly(P<0.05),but the corneal astig-matism had no significant difference between preopera-tion and postoperation; the BCVA and corneal astig-matism in 1 week, 1 month and 3 months after surgery had no statistical difference within the group or between the groups. There were no complications such as abnormal intraocular pressure, bullous keratopathy or suppurative endophthalmitis occurred in both groups after surgery.·CONCLUSION: Extracapsular cataract extraction com-bined with intraocular lens implantation by two kinds of converse frown and trapezoidal scleral small incision both have advantages like quick recovery of visual acuity, small astigmatism, safe and convenient, no need of ex-pensive equipment, they are suitable to be used in basic hospitals.
