AIM: To compare the clinic effects of implanting two kinds of artificial lens(Bigbag and US)in patients of high myopia with cataract.

METHODS: A total of 56 cases were studied retrospectively. Patients in group A(31 cases with 55 eyes)were implanted in Bigbag intraocular lens and patients in group B(25 cases with 40 eyes)were implanted in US intraocular lens. Best corrected visual acuity(BCVA), anterior chamber depth, and post operative complications were measured and compared 3 months after surgery.

RESULTS: There was no significantly difference between group A and B in BCVA 3 months after surgery. Anterior depth of group A was deeper than group B, which was statistically significant difference(P<0.05). Three month after surgery, patients in group A(5 eyes, 9.1%)who felt more floating shadows were less than patients in group B(10 eyes, 25.0%), which was statistically significant difference(P<0.05); The incidence of posterior capsule opacification(PCO)in group A(2 eyes, 3.6%)is less than patients in group B(3 eyes, 7.5%), which was statistically significant difference(P<0.05).

CONCLUSION: Bigbag has obvious advantages such as reducing complications and the incidence of PCO than US for patients of high myopia with cataract.
