背驮式人工晶状体植入在小眼球手术中的应用

The clinical application on operation of nanophthalmos using piggyback IOL.

目的观察单眼背驮式人工晶状体植入在真性小眼球白内障术中的临床效果。方法对4例眼轴在16.37~18.50mm之间的真性小眼球行白内障超声乳化双人工晶状体植入术,观察其术后视力、屈光状态、前房深度及眼压变化。结果4例术后获得较好的裸眼视力,远视度数明显减轻(+4.00D^-0.50D),前房加深,眼压正常。结论真性小眼球植入背驮式人工晶状体可改善裸眼视力,矫正远视状态并加深前房。

Objective To observe the clinical effect of operation of nanophthalmos with implanting monocular piggyback intraocular lens. Methods Performing phacoemusification with double IOL for 4 nanophthalmos patients whose oculi axes are between 16.37 - 18.50ram, then recording the postoperative chang of their visual acuity, refraction, deep of anterior chamber and intraocular pressure. Results 4 patient＇s postoperative visual acuity of naked eye are good. Their hyperopia have been improved singificantly（ ＋ 4.00- - 0. 5D）. Anterior chamber are deeper,IOP is nomal. Conclusion Nanophthalmos with double implanted can improve the visual acuity of naked eye,correct the hyperopia and deepen anterior chamber.
