Primary outcomePrimary: Distance Against the Rule Astimatism — 0.01 LogMAR
Summary
Low amounts of postoperative residual astigmatism may worsen the visual performance of patients implanted with presbyopia- correcting intraocular lenses (IOLs). Although extended depth of focus (EDoF) IOLS have introduced optical improvements, it is important to determine the tolerance of these IOLs to postoperative astigmatism. This is important for an appropriate surgical planning.
Therefore, the aim of this study is to simulate and assess the impact of mild amounts of residual mixed astigmatisms with the axis oriented in different positions (vertical, oblique and horizontal) in eyes implanted with the Vivity® IOL.
