Ocena zdolności akomodacyjnych układu wzrokowego w zależności od wieku z zastosowaniem systemu WASCA

Introduction
The aim of this study was, to analyse the results of accommodation range measurement obtained in groups of patients of different age. Wavefront aberrometer was used for evaluation of accommodation range of the patients eyes.

Material and methods
The accommodation range was analysed in 200 eyes in 100 patients. The examined group of patients was divided into 4 groups, depending on the patients age. Group I – age: 20-30 years old; group II – age: 31-40 years old; group III – age: 41-50 years old; group IV – age: 51--60 years old. The measurements were analysed using WASCA System depend on: refractive error, sex and difference of pupil diameter for far and near vision.

Results
Different ranges of accommodation were obtained. We did not observe any correlation between the accommodation range and the sex and refractive error. We noticed statistically significant differences between the accommodation range and pupil diameter, as well as the patients' age.

Conclusions
The WASCA System is a device, which can be used for analysis of accommodation range. This system gives us the possibility, to trace changes of eye accommodation range in the long period of time.
