Visual Acuity Clinical Trial
Age related cataracts are responsible for about 51 percent of blindness worldwide and
according to the WHO affect about 20 million people, according to the WH . As cataract
surgery is firstline treatment in the western world, there is a constant attempt to improve
artificial intraocular lenes (IOL).
As for this study, the investigators seek to compare four different IOL designs in in a
psychophysiological setting, allowing to assess the impact of these IOLs on vision and
psychological processing of visual information.
As these IOLs also have downsides, such as reduced light intensity or image alterations, the
subjective preference and overall impression shall be investigated. The healthy subjects
look through a stable spectacle frame mounted onto a table, which enables the investigator
to insert the different IOLs. This would allow subjective testing of IOLs before surgery.
