Abstract Details

Purpose:

To assess the impact of 0.50 diopter (D) positive or negative defocus on halo perception in patients implanted with trifocal and trifocal toric intraocular lenses (IOLs).

Setting:

Clínica Rementería, Madrid, Spain.

Methods:

The study included patients implanted with the AcrySof® IQ PanOptixTM IOL or the PanOptixTM Toric. Clinical assessment of photic phenomena were performed with distance correction (CDVA) as an ideal emmetropic situation, with a positive defocus of +0.50D (myopization) and with a negative defocus of -0.50D (hyperopization). The proportion of patients in which halo perception exceed predefined clinical limits of tolerance was also analyzed.

Results:

The study included 60 eyes of 60 patients (30 eyes with PanOptix and 30 eyes with PanOptix Toric). For both groups, the halo effect was lower for the ideal emmtropic situation if compared to myopization and hyperopization (p<0.05 for all cases) with no statistically significant differences between both defocus situations (p=0.13 for the Panoptix and p=0.37 for the Panoptix Toric group).

Conclusions:

There is an impact on halo perception in patients implanted with trifocal and trifocal toric IOLs even for low residual refractive errors and there is a non-negligible proportion of patients that will complain due to increased photic phenomena
