AIM:To investigate the effects of Bigbag and Rayner620H intraocular lens in cataract surgeries in high myopia patients.

METHODS:Seventy-seven patients(128 eyes)were treated by phacoemulsification combined with intraocular lens implantation from January 2014 to March 2015 in our hospital. Thirty-nine patients(65 eyes)were treated with Bigbag intraocular lens, 38 cases(63 eyes)were treated with Rayner620H. The best corrected visual acuity(BCVA)distribution, the actual refractive value, the difference between predictive refractive value and actual refractive value and complications were measured and recorded in the two groups at 1mo after surgeries.

RESULTS:The difference between the two groups on BCVA are statistically significant(P<0.05), compared by Wilcoxon rank sum test. The differences between predictive refractive value and actual refractive value of the two groups were statistically significant(P<0.05). The numbers of patients with shadow fluttering, posterior capsule opacification and wrinkling in Bigbag group were less than those in the Rayner620H group(P<0.05).

CONCLUSION:The effect of Bigbag intraocular lens for patients with phacoemulsification and intraocular lens implantation is good, and it can reduce the risk of complications.
