Abstract Details

Purpose:

To assess surgical outcomes, postoperative best measured distance visual acuity (CDVA), uncorrected distance visual acuity (UDVA) and patient satisfaction in amblyopic subjects after refractive lens exchange (RLE) with implantation of multifocal intraocular lenses.

Setting:

Optegra Eye Hospitals, UK

Methods:

The electronic medical records from patients that underwent RLE at 7 different hospitals in the UK between 2011 and 2016 and had completed a postal satisfaction questionnaire at least 2.5 years after surgery, was retrospectively analysed statistically. Inclusion criteria for amblyopic subjects were: monocular pre-operative CDVA equal or worse than 0.30 logMAR in at least one eye and a difference in CDVA between eyes of 0.2 logMAR or more. Patients whose indication for surgery was “clear lens extraction for refractive reasons”, and with amblyopia recorded in the record, were included.

Results:

Nine eyes from 9 patients (mean age 58±7) were included. There was a significant improvement in vision for the amblyopic eyes postoperatively (pre-op CDVA 0.40 ± 0.16 logMAR; post-op UDVA 0.16 ± 0.19 logMAR, p = 0.028). The mean difference in CDVA and UDVA between eyes before and after surgery, respectively; was significantly reduced postoperatively (0.44 ± 0.25 logMAR Vs 0.17 ± 0.22 logMAR, p = 0.032).  Patient expectations were met or exceeded regarding quality of vision (100%), spectacle independence (89%) and incidence of ghosting or doubled images (86%).  88% said they would have the surgery again.

Conclusions:

The study data suggests that amblyopic patients may benefit from multifocal intraocular lens implantation which, when appropriately counselled, can result in high levels of patient satisfaction.
