Abstract Details

Purpose:

To report the visual and refractive outcomes following monocular implantation of an add – on secondary IOL to correct residual refractive errors following lens bases surgery.

Setting:

University Hospital Ayr, Ayr, Scotland, UK.

Methods:

Prospective interventional case series. 5 eyes of 5 subjects with residual refractive error following previous lens based surgery were included. 3 to 6 months following the primary surgery subjects underwent a secondary procedure during which a custom designed add on IOL was implanted in the ciliary sulcus. The mean residual refractive error varied from minus 1.5D to plus 1.5D A commercially available on line calculator was used from the IOL manufacturer to calculate the IOL power of the add – on IOL for emmetropia. Distance visual acuity was recorded on day 1, week 1 & 4, month 3 & 6.

Results:

There were no intra- or post-operative complications. The average uncorrected distance visual acuity improved from 0.4 LogMAR pre-operatively to 0.0LogMAR post-operatively. Spectacle independence for distance vision was achieved in all patients. There was no change in intraocular pressure pre and post operatively.

Conclusions:

Unilateral implantation of an add - on secondary IOL seem to be a safe and effective option in achieving spectacle independence and to correct unexpected residual refractive errors following lens based surgery. However a larger cohort and a longer follow up is required to assess the long term efficacy of this procedure.
