Abstract Details

Purpose:

The aim of the study was to compare the qualitative changes of vision in amblyopic patients who underwent refractive lens exchange (RLE) with trifocal intraocular lens (IOL) implantation. We have specified indication criteria and evaluated the subjective satisfaction of these patients.

Setting:

European Eye Clinic Lexum, Prague, Czech Republic

Methods:

In this cohort study, we evaluated the outcomes of RLE in 36 eyes of 34 patients with amblyopia in one or both eyes after bilateral implantation of trifocal lenses. Mean patient age was 55±6 years (43-68 years). Implanted IOLs were AT LISA tri 839MP (Carl Zeiss Meditec) and FineVision Micro F (PhysIOL), including their toric versions. Mean follow-up period was 5 months. Patients underwent complex preoperative ophthalmologic examination, including testing for strabismus. Inclusion criteria for trifocal lens implantation was CDVA of 0.4 logMAR and better in amblyopic eye, together with maintained fusion capability. Satisfaction was assessed using non-standardised questionnaire.

Results:

Mean preoperative spherical equivalent (SE) was 3.59 ± 2.96 D (-4.63 to 8.00 D). Mean uncorrected distance visual acuity (UDVA) improved from preoperative 0.87 ± 0.31 logMAR (0.10 to 1.30 logMAR) to postoperative 0.18 ± 0.10 logMAR (0.04 to 0.40 logMAR). Mean preoperative corrected distance visual acuity (CDVA) was 0.18 ± 0.08 logMAR (0.04 to 0.40 logMAR), while postoperative value was 0.14 ± 0.08 logMAR (0.04 to 0.30 logMAR). Patients were satisfied with the outcome of the surgery.

Conclusions:

This study shows that in suitably selected patients with amblyopia refractive lens exchange with implantation of trifocal intraocular lenses may substantially improve uncorrected visual acuity. Outcomes are supported by a high patient satisfaction with their postoperative vision.
