Outcome of Zeiss AT LARA EDOF Lens Implantation in Vitrectomized Eyes

Study Overview
=================
Brief Summary
-----------------
To determine the surgical outcome and patient satisfaction in patients who underwent AT LARA lens implantation during or after vitrectomy at a relatively young age (around 55 years of age), mostly to treat (urgent) retinal detachment.

Detailed Description
-----------------
The surgical outcome is defined as the patient satisfaction determined by patient questionnaires. Visual quality: CatQuest questionnaire Near vision: NAVS questionnaire Glare: APPLES questionnaire These questionnaires are standardized and validated, although no cut-off values have been determined. Hence, the results drawn from these questionnaires are descriptive only.
