AIM: To compare the visual functional outcomes with accommodating and multifocal
intraocular lenses (IOLs). METHODS: Our retrospective comparative study included
51 patients (60 eyes) received implantation of an accommodating IOL (Tetraflex;
16 patients, 20 eyes), a refractive multifocal IOL (ReZoom; 18 patients, 20
eyes), or a diffractive multifocal IOL (ZMA00; 17 patients, 20 eyes). Subjective
refraction, visual acuity, contrast sensitivity (CS), intraocular aberration, and
subjective photic phenomena were detected at 3mo after surgery. RESULTS: The
spherical equivalent in the three groups was -0.38±0.54 D, 0.14±0.56 D, and
0.35±0.41 D, respectively. No statistically significant differences were found in
uncorrected and corrected distance visual acuity and uncorrected intermediate
visual acuity among the groups (P=0.39). The ReZoom group had significantly
better distance-corrected intermediate visual acuity than the ZMA00 group
(P=0.003). The ZMA00 group had significantly better near visual acuity than the
other groups (P<0.05). Better contrast sensitivity values were observed in the
Tetraflex group under most of the spatial frequencies conditions (P=0.025). The
total aberration was lowest in the ZMA00 group (P=0.000), and the spherical
aberration was highest in the Tetraflex group (P=0.000). The three groups had
similar frequency of ghosting and glare, and the Tetraflex group had a low rate
of halos (P=0.01). CONCLUSION: Both accommodating and multifocal IOLs can
successfully restore distance and uncorrected intermediate visual acuities.
Tetraflex accommodating IOLs perform better in CS and with less halos of photic
phenomena. ReZoom refractive multifocal IOLs have better performance in
distance-corrected intermediate visual acuity than ZMA00 diffractive multifocal
IOLs, and the latter achieved better near visual acuity and efficiently decreased
the optical aberration.
