Brief Summary:
Population 1:
Measure the effect of size glasses from1-9% on stereopsis
Population 2:
Measure the effect of size glasses from 1-9% on stereopsis in two settings:
* before and after cataract surgery
* after dilation of the eye
Measure the effect of size glasses from1-9% on stereopsis
Population 2:
Measure the effect of size glasses from 1-9% on stereopsis in two settings:
* before and after cataract surgery
* after dilation of the eye
Detailed Description:
Population 1:
21 eye healthy phakic individuals. Measurements: baseline stereopsis and stereopsis after size glass (1-9%) is added in front of the right eye and in front og the left eye. This measurement provides details on how much size difference a person can endure without impairing stereopsis.
Population 2:
11 phakic eye healthy individuals awaiting cataract operation on both eyes. Measurements are the same as population 1 but this study group is also measured after dilating the eyes. This is to see if accommodation affects the measurement. A postoperative measurement six weeks after cataract operation is also performed to examine if cataract operation affects the measurement.
