To investigate the presence of apparent accommodation in monocular pseudopakic eyes and contact lens wearing monocular aphakic eyes, we measured it in 54 monocular pseudophakic eyes (54 patients) and 40 contact lens wearing monocular aphakic eyes (40 patients). The mean apparent accommodation was 1.68±1.25 diopters in monocular pseudophakic eyes and 1.74±0.73 diopters in contact lens wearing monocular aphakic eyes, and there was no statistically significant difference between them. Apparent accommodation was not related either to type of intraocular lenses or pupil size in pseudophakic eyes and not related to target size in aphakic eyes, but it was influenced by pupil size in aphakic eyes. In the group of patients aged between 45 and 55, accommodation in phakic eyes was significantly greater than apparent accommodation in contralateral contact lens wearing monocular aphakic eyes.
