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.
