Abstract Details


To compare the visual and ocular optical performance of eyes implanted with either a Single-optic or a Dual-optic accommodative intraocular lenses (IOLs).


Vissum Corporation, Alicante, Universidad Miguel Hernįndez, Alicante, Spain.


53 eyes of 39 cataract patients (age range 59-82 years) were divided into two groups: group A, 27 eyes implanted with the single-optic accommodating IOL Crystalens HD (Bausch & Lomb); group B, 26 eyes implanted with the dual-optic accommodating IOL Synchrony (Visiogen, Inc). Distance and near visual acuity outcomes as well as contrast sensitivity, ocular aberrations, reading performance and the defocus curve were evaluated postoperatively during a 3-month follow-up.


Significantly better values of uncorrected distance visual acuity and corrected distance visual acuity were found in group B (p?0.04). No significant differences between groups were found in near and intermediate visual outcomes (p?0.13). In the defocus curve, significantly better visual acuities were present in eyes from group B for several levels of defocus (p?0.04). The ocular Strehl ratio and contrast sensitivity were significantly better for group B (p?0.04). Higher values of postoperative total and higher order root mean square (RMS) aberrations were observed in group A (p?0.01).


Both IOLs are able to restore the distance visual function after cataract surgery with limitations in near visual outcomes. Eyes with the Dual-optic IOL presented a more significant ocular optical quality, leading better distance visual outcomes. FINANCIAL DISCLOSURE?: No
