Visual and Refractive Outcomes of a Hydrophobic Trifocal Diffractive Intraocular Lens in Eyes with Different Axial...

To analyse the clinical outcomes of a hydrophobic trifocal diffractive intraocular lens (IOLs) implanted in eyes with different axial lengths.

This prospective study enrolled 116 eyes implanted with the FineVision HP IOL (Beaver-Visitec International, Inc. USA). The eyes were allocated into 3 groups according to their preoperative axial length: Group A (21.00-22.50 mm, n=17), Group B (>22.50-24.00 mm, n=83), and Group C (>24.00-28.50 mm, n=16). Post-operative outcomes at 3 months considered manifest refraction, monocular LogMAR uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and uncorrected near visual acuity (UNVA) and distance-corrected near visual acuity (DCNVA, at 40 cm).

For Group A, 70.59% and 100% of eyes were within ±0.50D and ±1.00D, respectively (mean spherical equivalent [SE]: 0.23±0.39D); for Group B, these figures were 84.34% and 100%, respectively (mean SE: -0.12±0.41D); and for Group C, all eyes were within ±0.50D (mean SE: 0.16±0.21D). SE did not differ between groups (p>0.4). The mean CDVA was -0.01±0.07, -0.02±0.06, and -0.05±0.07 for Groups A, B, and C, respectively (p=0.147), and the mean DCNVA was 0.09±0.03, 0.08±0.05 and 0.09±0.03, respectively (p=0.716). For distance vision, in Group A, 76.47% and 100% of eyes had a cumulative CDVA of ≥20/20 and ≥20/25, respectively. These percentages changed to 92.77% and 100% for Group B, and 93.75% and 100% for Group C, respectively. For near vision, for Group A, 11.76% and 100% of eyes had a cumulative DCNVA of ≥20/20 and ≥20/25, respectively. These percentages changed to 18.07% and 100% for Group B, and 12.50% and 100% for Group C, respectively.

The hydrophobic trifocal diffractive FineVision HP IOL provides good visual and refractive outcomes for eyes with different axial length.
