Abstract Details
Purpose:
To assess the impact of 0.50 diopter (D) positive or negative defocus on visual quality 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. Visual acuity (VA) at high (100%), medium (50%) and low (10%) contrast and contrast sensitivity function (CSF) were analysed monocularly three months after surgery. Explorations were performed with distance correction (CDVA), with a positive defocus of +0.50D (myopization) and with a negative defocus of -0.50D (hyperopization). The proportion of patients in which the worsening of VA 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, VA was better for all contrast settings at the CDVA situation (p<0.05 in all cases). For low spatial frequencies, no differences in CSF were found among the three refractive situations in either group (p>0.05 in all cases). For higher frequencies, the results showed an overall trend for better CSF results for the CDVA situation.
Conclusions:
There is an impact on visual quality in patients implanted with trifocal or trifocal toric IOLs even for low residual refractive errors. At the same time, there is a non-negligible proportion of patients that will complain due to decreased visual quality.
