Abstract Details

Purpose:

To assess visual results after bilateral implantation of rotationally asymmetrical MFIOL focused for distance and near.

Setting:

Cathedral Eye Clinic, Belfast, Northern Ireland, UK

Methods:

Forty consecutive patients with bilateral implantation of SBL-3 (Lenstec) rotationally asymmetric MFIOL were followed for 6-month with distant dominant in 1 eye (dominant eye) and a near dominant in the fellow eye. This was achieved by actively rotating the asymmetrical MFIOL within the pupil during surgery to increase or decrease the distance-add and near-add exposure. Distance (UDVA), intermediate (UIVA), and near (UNVA) visual acuities and quality-of-vision (QOV) questionnaire scores were evaluated preoperatively and at 1, 3 and 6 month postoperatively. A control group of age-matched bilateral monofocal pseudophakic patients was included to compare.

Results:

In the multifocal group, mean binocular UDVA (logMAR) was -0.1 ± 0.07 (6-month) and -0.1 ± 0.12 (1-month). The mean binocular UNVA (logMAR) was -0.05 ± 0.10 (6-month) and -0.03 ± 0.01 (1-month). The mean binocular UIVA (logMAR) was 0.18 ± 0.13 (6-month) and 0.21 ± 0.12 (1-month). The mean patient QOV score for day and night at 6-month was 9.3 and 8.5 respectively (scale 0 to 10); 86.9% of patients were completely independent of spectacles. 5.2%, 9.5%, and 3.5% of patients reported moderate halos, glare, and dysphotopsia, respectively.

Conclusions:

The rotationally asymmetrical MFIOL provided good UDVA, UIVA and UNVA with no anisometropic blur; high rates of spectacle freedom was recorded as the dominant eye was targeted for distant-dominant and the fellow eye for a near-dominant.
