Abstract Details

Purpose:

This study aimed to assess the influence of different ophthalmic conditions after cataract surgery (extended range of vision IOL with micromonovision, minimonovision with standard IOL and single focus distance vision with standard IOL) on reading quality using an eye tracker device to evaluate reading speed, ocular fixation times and saccades.

Setting:

Vienna Institute for Research in Ocular Surgery (VIROS), a Karl-Landsteiner institute, Hanusch Hospital, Vienna, Austria

Methods:

In this ongoing prospective study, a total of 45 pseudophakic patients will be enrolled in three different groups of 15 patients each, extended range of vision IOL (Symfony Tecnis, Abbott), minimonovision standard IOL and single focus distance vision with standard IOL. Each patient's reading performance and eye movements were evaluated with the eyetracker Eyelink 1000 (SR Research Ltd, Canada) at photopic and mesopic lightning conditions and number of fixations, the fixation duration, the forward saccadic length and the percentage of backward saccades (regressions) and reading speed were analysed.

Results:

Preliminary data of 15 patients with Symfony IOL will be presented at ESCRS meeting.

Conclusions:

Fixation, duration of fixation and saccades of pseudophakic patients with different IOLs lead to a better understanding of reading behaviour and consequently IOL choice.
