Convergence ability in patients after cataract phacoemulsification and patients with their own lens
Journal Title: Annales Academiae Medicae Silesiensis - Year 2017, Vol 71, Issue
Abstract
INTRODUCTION: The aim of this study was to determine whether convergence varies with age and pseudophakia. MATERIAL AND METHODS: 86 patients, aged 21–85 (average age: 62.7) years were included in the study group: 39 patients with binocular pseudophakia and 41 with their own lens, as well as 68 people with their own lens, at the age of 19–25 (average 22.1) years. Examinations were carried out at distances of 50 and 10 cm, and for distant vision. Interpupillary distance measurements were used to calculate the difference of convergence capabilities. The examination results of phakic and pseudophakic eyes were compared. RESULTS: The mean convergence of the pseudophakic patients was 3.52 mm (± 0.42 mm), in the patients with their own lens: 3.46 (± 0.74 mm). No statistically significant differences between the groups were found. No statistically significant difference was found in the mean convergence between the two groups of patients aged 19–25 (group 1) and over 65 years (group 2), either. The average value of convergence in group 1 was 3.47 mm (3.84–2.93 mm). Ho-wever, in the second group the values were 3.46 mm (3.96–2.48 mm). There was no evidence of statistical differences in the average value of convergence in both groups for distances of 50 cm and 10 cm. CONCLUSIONS: Convergence does not depend on age. Presbyopia does not lead to a loss of convergence in phakic or pseudophakic eyes.
