Purpose

The aim of this study is to assess and compare the visual quality and satisfaction of patients with a hybrid intraocular lens (IOL) that combines a diffractive-based extended depth of focus profile with a diffractive multifocal pattern or with its toric version.

Setting

Clínica Rementería, Madrid, Spain

Methods

This preliminary study included 64 eyes of 32 patients having bilateral implantation of the TECNIS Synergy™ (16 patients) or the TECNIS Synergy™ Toric II IOL (16 patients). Three months after the surgery monocular and binocular uncorrected (UDVA), corrected distance VA (CDVA) at different contrast (100, 50 and 10%) and binocular defocus curves were measured. Patients also completed a five points Likert scale questionnaire reporting about satisfaction at different distances and perceived halo.

Results

For the non-toric group, monocular and binocular UDVA were: 0.00±0.08 and -0.05±0.06 logMAR, respectively; and for the toric group: 0.11±0.15 and 0.00±012 logMAR, respectively. Monocular CDVA was -0.01±0.08 logMAR for the non-toric and 0.01±0.06 logMAR for the toric group (p=0.21). Binocular defocus curves showed values over 0.1 logMAR between +1.0 and -2.5D of vergence for both groups. CDVA at 100, 50 and 10% of contrast showed no differences between groups (p>0.05 for all cases). In both groups, > 75% of patients were “satisfied” or “very satisfied” with their vision at all distances. In both groups, around 40% of patients described the halo effect as “not at bothersome” or “slightly bothersome”.

Conclusions

In the current study, visual outcomes were similar with both IOLs analyzed and they restored VA from distance to near. After an optimal alignment, visual quality and patient satisfaction with the trifocal toric lens is equivalent to the non-toric version of the same platform design. A larger sample is needed to reinforce the results
