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

The preoperative refraction values were +17.75DS -1.50DC × 168° for the right eye and +17.25DS -0.75DC × 8° for the left eye. The uncorrected visual acuity (UCVA) was 20/200 bilaterally and the spectacle-corrected visual acuity (BSCVA) was 20/50 bilaterally. One year after Artisan iris-fixated IOL implantation, bilateral BSCVA was 20/50 with a refraction of +1.25DS -0.75DC × 13° for the right eye and +1.50DS -1.00DC × 55° for the left eye. The outcomes of an Artisan iris-fixated IOL implantation followed to CLE with PC-IOL implantation were encouraging for the correction of extreme hyperopia. Long term follow-up examinations were necessary for further determination of the efficacy and safety of this combinational procedure.展开更多
