3.2mm切口手法碎核白内障摘除联合折叠式IOL植入术的疗效观察

目的：观察3.2mm切口手法碎核白内障摘除联合折叠式人工晶状体植入术的临床效果。

方法：观察组：对我院78例95眼老年性白内障行3.2mm切口手法碎核白内障摘除联合折叠式人工晶状体植入术； 对照组：对同期82例100眼老年性白内障行超声乳化白内障摘除联合折叠式人工晶状体植入术。观察并比较手术并发症及术后视力恢复情况。

结果：观察组术中有2眼(2.1%)后囊膜破裂，3眼(3.2%)局限性悬韧带离断。术后切口方位角膜轻中度水肿混浊18眼(18.9%)，1wk内前房闪辉22眼(23.2%)。对照组术中有3眼(3.0%)发生后囊膜破裂，4眼(4.0%)局限性悬韧带离断。术后角膜轻中度水肿混浊21眼(21.0%)，1wk内前房闪辉26眼(26.0%)。两组均无后弹力膜脱离、前房出血、伤口渗漏及感染发生。两组并发症比较差异无统计学意义(P>0.05)。两组术后视力比较差异无统计学意义(P>0.05)。

结论：3.2mm切口手法碎核行白内障摘除联合折叠式人工晶状体植入术操作安全、简便，具有小切口手术的优点，适于临床推广和普及。

Clinical observation on 3.2mm incision manual fragmentation cataract extraction combined with IOL in cataract

AIM: To observe the clinical effect of 3.2mm incision manual fragmentation cataract extraction combined with intraocular lens(IOL)implantation in cataract.

METHODS: The observation group: 78 patients(95 eyes)with senile cataract in our hospital underwent 3.2mm incision and manual extraction combined with IOL implantation in nucleus cataract; the control group: 82 cases(100 eyes)with senile cataract underwent phacoemulsification and foldable IOL implantation. Operation complications and the recovery of postoperative visual acuity were observed.

RESULTS: The patients in the observation group, 2 eyes(2.1%)of posterior capsule rupture, 3 eyes(3.2%)limitations zonule; postoperative range of mild to moderate corneal edema and opacity in 18 eyes(18.9%), within one week of the flare in 22 eyes(23.2%). The control group was in 3 eyes(3.0%)happened posterior capsule rupture, 4 eyes(4.0%)limitations zonule; mild to moderate edema of corneal opacity in 21 eyes(21.0%), within one week of the flare in 26 eyes(26.0%). The two groups were no elastic membrane detachment, anterior chamber hemorrhage, wound leakage and infection. The two groups had no statistically significant difference in complication(P>0.05). The two groups had no statistically significant difference in postoperative visual acuity(P>0.05).

CONCLUSION: 3.2mm incision manual nucleus cataract extraction and IOL implantation operation is safe and convenient, has the advantages of small incision operation, suitable for clinical promotion and popularization.
