INTRODUCTION

The goal of multifocal intraocular lenses (IOLs) is to provide clear and comfortable vision to patients at all viewing distances

Trifocal diffractive lenses were developed to address the intermediate vision limitations of bifocal IOL designs

Optical bench studies indicated peak IOL performance at 42 cm for near and at 60 cm for intermediate, and at 39 cm for near and at 80 cm for intermediate with Panoptix and Finevision trifocal IOLs, respectively.

PURPOSE

To compare the visual outcomes one month after cataract surgery in patients receiving bilateral implantation of Panoptix or Finevision trifocal IOLs.

Panoptix IOL vs finevision ICL

PATIENTS AND METHODS

Consecutive patients undergoing bilateral cataract surgery or lensectomy were evaluated for inclusion in the study

Patients receiving bilateral Panoptix IOLs were included in group 1 and patients receiving bilateral Finevision IOLs in group 2.

Patients who were diagnosed with any ocular pathology apart from cataracts which could compromise visual acuity or produce a visual field defect were excluded, as well as patients presenting intra or postoperative complications.

One month after surgery en extensive ophthalmic evaluation was performed, including photopic and mesopic mono and binocular visual acuity for far (4 metres), intermediate (60 cm) and near (33 cm) distances

A monocular defocus curve and binocular contrast sensitivity were also performed

The monocular defocus curve was very similar between groups, with a better visual function in group 1 for -1.50 D and group 2 at -1.00 D

There were no statistically significant differences in binocular contrast sensitivity

Defocus curve Panoptix Vs Finevision

Contrast sensitivity Panoptix Vs Finevision

CONCLUSIONS

Panoptix and Finevision trifocal diffractive lenses have very good visual results for far, near and intermediate vision one month after cataract surgeries

Panoptix lens has a better intermediate vision at 60 cm both under photopic and mesopic luminance conditions. 

Defocus curves are similar with an optimum performance between -2.50 and +0.50

There are small differences in the optimum working distance for intermediate vision for each lens

There is a trend towards a better contrast sensitivity with the Panoptix lens

The small sample size causes that some of the results are inconclusive
