Design outcomes

Primary

Measure	Time frame
To evaluate the influence of a short term anaesthesia (60 to 90 minutes) on cognitive function in visually impaired patients Tests: - 6-CIT -- Six Cognitive Item Test -- Screnning on preoperative cognitive dysfunction - MoCA blind: Montreal Cognitive Assessment for the blind - CFQ: Cognitive failure questionnaire MoCA and CFQ will be applied to detect POCD. Both tests will be performed the day before surgery, on postoperative day 3 and 2-3 weeks after surgery.	—
