Abstract
Purpose :
To conduct a retrospective case analysis of eyes that underwent secondary intraocular lens (IOL) placement in order to compare the surgical technique and post-operative visual outcomes and complications among anterior chamber, Artisan iris-claw, and scleral-sutured IOLs.
Methods :
A retrospective case analysis that included 148 eyes from 145 patients that underwent surgery for placement of one of three types of secondary IOLs: anterior chamber intraocular lens (ACIOL), Artisan iris-claw intraocular lens (IC-IOL), or scleral-sutured intraocular lens (SSIOL). A total of 41(27.7%) eyes from 40 patients underwent ACIOL placement, 19 eyes (12.8%) from 18 patients underwent Artisan IC-IOL placement, and 88 eyes (59.46%) from 87 patients underwent SSIOL placement. Data extrapolated included reason for secondary IOL placement, type of secondary IOL inserted, pre-operative best corrected visual acuity (BCVA), BCVA at post-operative month 1 (POM1), overall BCVA after surgery, BCVA at the time of last follow-up appointment, length of follow-up period, and post-operative complications.
Results :
ACIOLs and SSIOLs resulted in a statistically significant improvement in ΔlogMAR at POM1, final visual acuity, and post-operative BCVA; whereas, Artisan IC-IOLs did not (see IMAGE 1). There was no statistically significant association between lens type and any complications. Artisan IC-IOL patients had a smaller sample size, better pre-operative visually acuity (p < 0.01), and shorter follow up time (p = 0.003). There was no statistically significant difference in final (p = 0.564) or post-op (p = 0.188) logMAR between lenses.
Conclusions :
ACIOLs, SSIOLs, and Artisan IC-IOLs are all reasonable secondary IOL options. Considerations include surgeon preferences as well as patients’ anatomic restrictions. The Artisan IC-IOL resulted in a better post-operative visual acuity at all time points measured; however, this was not statistically significant. Primary weaknesses of the data included the smaller sample size of the Artisan IC-IOL, significantly better pre-operative visual acuity of IC-IOL patients, and the relatively short follow up time for IC-IOL patients. It is possible that further data collection of the Artisan IC-IOL will yield more meaningful results, which we are actively investigating.
