Purpose

To demonstrate that binocular visual simulators (SimVisGekko; 2EyesVision, Madrid) allow patients to experience and perceive differences in the visual experience provided by different simulated presbyopic corrections before surgery even in the presence of cataracts. To compare the quality of vision preoperatively with different simulations and postoperatively with the corresponding real intraocular lens (IOL) implanted in the same patients. Through this study we also illustrated different patients IOL preferences and the integration of a visual simulator into the clinical workflow.

Setting

Hospital da Luz Lisboa, Lisbon, Portugal

Methods

Binocular defocus curves were evaluated in 19 cataractous subjects (mean age: 58±7 years) preoperatively through 3 different SimVisGekko simulations (the IOL selected by the surgeon and 2 other options) and measured postoperatively in 15 subjects, who had undergone bilateral cataract surgery with the IOL in place. Cataract classification was made using the LOCSIII scale. The Multifocal Acceptance Score (MAS-2EV) was evaluated at far for the different corrections. A modified Catquest questionnaire was completed pre- and post-operatively, as well as a subjective patient feedback questionnaire and a surgeon questionnaire.

Results

In 67% of cases, the corrected distance visual acuity (VA) was equal or better than the VA at 0 D of defocus through the preoperative multifocal simulation. The RMS difference between the mean preoperative simulated and postoperative defocus curve with the IOL implanted was 0.17 D for all the studied IOLs (FineVision, PanOptix and Vivity). Mean MAS-2EV score during daylight and night-time was higher postoperatively for all 3 lenses (PanOptix (p<0.001)). 100% of patients agreed that SimVisGekko concept was easy and 93% agreed that SimVisGekko helped them understand differences between presbyopic correction options.

Conclusion

SimVisGekko™ allows patients with cataracts to experience different presbyopic corrections (including multifocal and modified monovision) before surgery. Subjects understood better the concept of multifocality through SimVisGekko, helping them to show preferences for a particular solution, which, in most cases, differs amongst individuals. Visual simulators can be implemented in the preoperative clinic workflow to improve the selection of presbyopic corrections.
