RESULTS: The mean improvement of uncorrected visual acuity(UCVA) was greater in IF-IOL group compared to the SF-IOL group(0.43 D±0.19 D vs 0.35 D±0.18 D, P 〈0.05). Moreover, 12(38.71%) eyes in IF-IOL group and 4(12.50%) in SF-IOL group had a higher postoperative UCVA than preoperative best corrected visual acuity(BCVA) while 9(29.03%) eyes in IF-IOLgroup and 18(56.25%) in SF-IOL group had a lower postoperative UCVA than preoperative BCVA. The myopic mean manifest sphere and mean cylinder magnitude were lower in the IF-IOL group than that in the SF-IOL group(-0.47 D±0.58 D vs 0.50 D±0.43 D, P 〈0.01; 0.84 D ±0.53 D vs 1.23 D ±0.70 D, P 〈0.05). No difference of corneal astigmatism and surgically induced astigmatism was found between the two groups. In addition, fewer complications were observed in IF-IOL eyes. CONCLUSION: IF-IOL implantation can give a significant improvement in vision with fewer complications than SF-IOL in patients with insufficient capsular support.展开更多
