[Intact accommodation in pseudophakic eyes].
BACKGROUND
The purpose of the cataract surgery should be to guarantee the physiology of a young eye, especially with the ability to accommodate. This study focuses on accommodative changes in pseudophakic eyes.


METHODS
Using the IOL Master (Carl Zeiss Jena), Scheimpflug camera EAS 1000 (Nidek) and Pupillograph (AMTech GmbH), detailed measurements of pseudophakic eyes for near and distance fixation were taken. The average age of all patients is 71 years.


RESULTS
With regard to the pseudophakic pupil movement a statistically significant decrease of the pupil size, for the light-influenced, and for the light-constricted pupil in near fixation could be shown. Furthermore, a statistically significant decrease of the pupil-constricting amplitude and a decrease of the reaction time after a light impulse was shown. Central vertical and horizontal corneal radii show significant increases with accommodation, which results in a decrease of the central corneal curvature. While reducing the anterior chamber depth, the pseudophakic eyes show a statistically significant minimising of the superior anterior chamber angle.


CONCLUSIONS
Pseudophakic accommodating eyes react similarly compared to the phakic accommodating eyes of young individuals.
