Clinical outcomes of anterior chamber IOL at Ⅰ stage versus sclera-fixed IOL at Ⅱ stage in complicated cataract surgeries with inadequate capsular support / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

AIM:To compare the clinical outcome of anterior chamber intraocular lens (IOL) at Ⅰ stage versus sclerafixed IOL at Ⅱ stage in complicated cataract surgeries with inadequate capsular support.METHODS:Complicated cataract surgeries with anterior chamber IOL (ACIOL) or scleral-fixated IOL implantation from January 2003 to December 2014 when capsular support was inadequate were included and analyzed.Postoperative best-corrected visual acuity (BCVA) were compared.Postoperative complications were recorded and analyzed.RESULTS:Totally 84 eyes and 79 eyes were included in the ACIOL group and in the scleral-fixated IOL group,respectively.The mean postoperative logarithm of minimal angle of resolution (LogMAR) BCVA at 1a was 0.30±0.64 and 0.33±0.34 in the ACIOL group and the scleral-fixated IOL group,respectively (t=0.407,P=0.712).The mean latest LogMAR BCVA was 0.67±0.55 and 0.62 ± 0.50 in the primary ACIOL group and the secondary scleral-fixated IOL group,respectively (t=0.225,P=0.545).There were more early postoperative complications in the ACIOL group (x2 =14.613.P＜0.001).No difference in late postoperative complications was found between the two groups (x2 =0.231,P=0.267).Regression analysis suggested that ACIOL and scleralfixated IOL implantation had similar latest postoperative LogMAR BCVA (t=0.397,P=0.957);however the existence of late complications were related with a worse final visual outcome (t=22.156,P＜0.001).CONCLUSION:The long-term differences in the visual outcomes and complication profiles after ACIOL at Ⅰ stage or scleral-fixated IOL implantation at Ⅱ stage in a complicated cataract operation are not found when capsular support is inadequate.
