Abstract Details


To evaluated the visual outcomes and optical quality of patient with a new diffractive multifocal lintraocular lens (IOL) with distance, near and intermediate focus.


Vissum Corporation, Alicante, Spain.


A prospective cohort study included 40 eyes of 20 bilateral cataract patients that had bilateral cataract surgery with implantation of tri-focal and aspheric Finevision IOL (Physiol). This IOL has two diffractive structure, one with +1.75 D addition and another one with +3.50 D addition for near vision at 80 and 40 cm respectively. All surgeries were performed using standard technique of microincision (MICS) phacoemulsification the same surgeon (JLA). Visual and refractive outcomes at distance, near and intermediate were analyzed during a 6 months follow-up. In addition the defocus curve, contrast sensitivity in mesopic condition and postoperative internal optical quality was evaluated with an integrated aberrometer (KR-1W, Topcon)


The mean age patient was 67.87 years (ranging 54 to 82 years old). The mean spherical equivalent at 6 month was -0.09 ± 0.47 (p= 0.69). The mean uncorrected distance visual acuity improved at 6 months from 0.70 ± 0.34 to 0.18 ±0.13 logMAR (p<0.01). The mean corrected visual acuity, corrected distance near visual acuity and corrected distance intermediate visual acuity at 6 moths postoperatively were 0.05 ±0.06, 0.16 ±0.13 and 0.17 ± 0.09 log MAR respectively. The ocular high order aberration (HOA) at 6 months was 0.74 ± 0.25 µm and no significant difference with 1 month postoperatively ocular HOA (p =0.18 Wilcoxon test). No statistical difference was observed in the internal HOA between 1 and 6 months with RMS value 0.53 ± 0.22 and 0.48 ± 0.20 respectively (p= 0.326). The internal HOA aberration show a few value of spherical aberration.


The trifocal Finevision IOL is able to restore successfully distance, near and intermediate visual function after cataract surgery. The defocus curve improve the bimodal profile of bifocal intraocular lenses with a satisfactory intermediate vision. It also provide a suitable intraocular optical quality in relation with other diffractive IOLs.
