Abstract
Purpose:
To assess the visual and refractive outcomes after implantation of the FineVision trifocal IOL (PhysIOL, Belgium).
Methods:
Fifty eyes of twenty five patients were implanted consecutively with the FineVision trifocal IOL. This IOL combine 2 diffractive profiles to achieve far, intermediate, and near correction. Outcome measures recorded 3 months postoperatively were uncorrected and distance-corrected (far, near, intermediate) visual acuities, defocus curve, contrast sensitivity, reading speed (radner vissum reading chart) and patients' quality of life (visual function questionnaire VFQ-25, halos and glare presence, overall satisfaction).
Results:
At the 3-month postoperative visit, the mean sphere was -0.16 ± 0.45 D and the mean cylinder -0.50 ± 0.55. Binocular uncorrected and best corrected distance acuity were 0,10 ± 0.11 and 0.03 ± 0.07 logMAR respectively. The mean binocular uncorrected best distance-corrected near acuity 0.11 ± 0.12 logMAR. The photopic defocus curve showed similar performance in intermediate and near distance with visual acuity around 0.1 logMAR. The speed reading improved from 69,7 ± 13.8 words per minute preoperatively to 94,7 ± 43,9 in the postoperative period. The photopic contrast sensitivity was within the standard normal range. The rate of spectacle independence for all the distances was higher than 85%. A low percentage of patients referred significative halos or ghost images.
Conclusions:
The FineVision trifocal IOL provided a satisfactory full range of vision with high optical quality and patient satisfaction.
