Abstract

Purpose : Previous studies have shown differences in peripheral refractive errors between phakic and pseudophakic eyes and tested the impact on peripheral contrast sensitivity using an adaptive optics (AO) visual simulator. In this study, peripheral contrast sensitivity and peripheral refractive errors were measured in age-matched phakic and pseudophakic human eyes in a clinical setting.

Methods : Peripheral contrast sensitivity at 20 degrees of the nasal field of view was measured monocularly in photopic lighting conditions in two age-matched groups of phakic (29 eyes) and pseudophakic (31 eyes) subjects wearing their best on-axis distance correction. The mean age of the subjects was 64 years (range: 57 to 75 years) and all pseudophakic eyes had the same monofocal IOL model implanted. Central and peripheral refractive errors were measured for the same eyes at 30, 20, 10 and 0 degrees of the nasal and temporal field of view using the Grand Seiko and the Complete Analysis System Aberrometer (COAS).

Results : The difference in peripheral contrast sensitivity between the phakic and the pseudophakic group, 0.21 log units, was statistically significant (p=0.007). The M and J0 values at that eccentricity were -0.5±0.7D and -0.7±0.4D for the phakic group, and -1.1±1.3D and -1.1±0.4D for the pseudophakic group measured with the Grand Seiko. Differences in peripheral aberrations were statistically significant in this study but lower than previously reported in the literature. Peripheral contrast sensitivity was also statistically significantly correlated with the amount of peripheral blur quantified by M+J0 (R2=0.32 and p=0.023). Additionally, good correlation was found between the peripheral refractive errors measured with the Grand-Seiko and the COAS devices (R2 = 0.83 and 0.93 for M and J0 respectively).

Conclusions : This study found a significant correlation between peripheral contrast sensitivity and peripheral refractive errors measured in age-matched phakic and pseudophakic eyes. The results of this study showed a good agreement between the peripheral contrast sensitivity differences measured between phakic and pseudophakic eyes and the value predicted using an AO system to simulate similar optical conditions [Venkataraman et al, BOE 2021].
