Abstract Details

Purpose:

To determine the visual outcomes of an aspheric, hydrophilic acrylic trifocal Intraocular lens at 3-6 months post-operatively.

Setting:

BMI Southend Hospital

Methods:

Subjects who were bilateral implanted with an acrylic hydophillic aspheric trifocal IOL were enrolled in the study. At 3-6 months; uncorrected distance (UCDVA) and near (UCNVA) visual acuity; best distance corrected distance (BCDVA), intermediate (BCIVA) and near (BCNVA) visual acuity; contrast sensitivity (CSV1000); Defocus curves; critical print size (CPS); subjective perception of visual quality (NAVQ and QoV); and glare (Zeiss glare simulator) were assessed.

Results:

The study enrolled twenty-six subjects (mean age 59±7yrs). The mean visual acuity values at 3-6 months were UCVA 0.01±0.08, UCNVA 0.22±0.10, BCVA -0.02±0.07, BCNVA 0.18±0.09 and BCIVA 0.23±0.12; Contrast sensitivity was 1.68±0.15 at 3cpd, 1.91±0.18 at 6cpd, 1.85±0.22 at 12cpd, and 1.69±0.16 at 18 cpd; CPS was 0.30±0.08 LogRAD; The defocus curves demonstrated a peak in acuity at the -1.50 (intermediate) and -3.00 (near) magnitudes of defocus. The subjective perception of the quality of near vision was high with a mean NAVQ score of 16.2±14.8.

Conclusions:

Post-operative visual acuity at distance intermediate and near was excellent. Contrast sensitivity was preserved across spatial frequencies and subjects were satisfied with their reading vision post-implantation.
