Abstract Details


This study aimed to assess the influence of different approaches to correct presbyopia after cataract surgery (extended range of vision IOL with micro-monovision, mini-monovision with standard IOL, and single focus distance vision with standard IOL as control) on reading quality using an eye tracking device to evaluate ocular fixation times and saccades.


Vienna Institute for Research in Ocular Surgery, Hanusch Hospital, Vienna, Austria


In this ongoing prospective study, a total of 45 pseudophakic patients are enrolled in 3 different groups of 15 patients each: extended range of vision IOL (Symfony Tecnis, J&J), minimonovision standard IOL with a difference od 1.25 D, and single focus distance vision with standard IOL as control group. Each patient's reading performance and eye movements were evaluated with the eyetracking device Eyelink 1000 (SR Research Ltd, Canada) at photopic and mesopic lighting conditions. The number of fixations, the fixation duration, the forward saccadic length and the percentage of backward saccades (regressions) and reading speed were analysed.


Preliminary data show that this methodology is feasible in this patient population. Results will be be presented at ESCRS meeting.


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