Abstract Details

Purpose:

In this work, an already established hybrid bi-aspheric micro-monovision technique and cohort was followed-up for 6 years and the outcomes are retrospectively analysed in 38 consecutive eyes (of 19 patients) treated using this method.

Setting:

Bergman Clinics Netherlands, private practice for refractive surgery

Methods:

A previous consecutive case series of patients treated with the hybrid bi-aspheric micro-monovision technique to correct presbyopia completed the 6-year follow-up. The last follow-up visit included measurement of monocular and binocular UDVA, UNVA, UIVA, manifest refraction, CDVA, DCNVA, DCIVA and defocus curves. The response to Quality of Vision and Near Activity Visual Questionnaires, topography and aberrometery, were recorded as well.

Results:

At six year follow up, mean binocular UDVA was 20/18±4 letters. Mean binocular UIVA was J1.0. Mean UNVA was J1.7 binocularly. Mean CDVA was 20/15±3 letters for DE; 20/19±5 letters for NE; and 20/14±3 letters binocularly. Asphericity was more prolate after surgery indicating a central myopia, confirmed by the induction of negative corneal and ocular spherical aberrations. Compared to the corrected preoperative scores, the (uncorrected) Quality of Vision at 6Y was comparable to pre-op (corrected) for all questionnaire items. The Near Activity Visual Questionnaire scores improved from little to high satisfaction level for all items and remained stable.

Conclusions:

Our study demonstrates significant success in presbyopic treatments using the hybrid bi-aspheric micro-monovision ablation profiles at 6-years' follow-up. We evaluated the subjective perception of patients for distance (Quality of Vision) and near visual quality (Near Activity Visual Questionnaire scores) and found significant improvements in the NAVQ scores with improved uncorrected and corrected near and distance visual acuity, and some reduction in QoV, remaining stable. Presbyopic treatment using a hybrid bi-aspheric micro-monovision ablation profile is safe and efficacious. The postoperative outcomes indicate improvements in binocular vision at far, intermediate and near distances, achieving sustained high levels of spectacle independence.
