Epiretinal membrane vitreoretinal surgery assisted by a robotic system as compared to standard surgery

INTERVENTION: Randomized patients 2:1 for robotic assistance vs standard surgery will undergo a vitreoretinal procedure to remove an epiretinal membrane. At various steps of the surgery, the step will be either carried out manually or with the assistance of a robotic system. The following steps will be studied: fluid staining, fluid‐fluid exchange, epiretinal flap initiation, epiretinal membrane grap and peel, light pipe orientation and positioning, air‐fluid gas exchange CONDITION: Macula pucker Epiretinal membrane Epiretinaal membraaan vision loss visus daling PRIMARY OUTCOME: Overall ‐ degree of nerve fiber layer changes at 3 months post surgery in an OCT macular cube.; For individual surgical step: presence/absence of surgical trauma, retinal hemorrhage; response of the surgeon to a standard questionnaire post surgery SECONDARY OUTCOME: Patient satisfaction based on a questionnaire. Similar evaluation on concerns by the operating room personnel. Time required for each surgical step and overall time involved in conducting surgery INCLUSION CRITERIA: Epiretinal membrane requiring surgery and confirmed on Spectral OCT scans BCVA (best corrected visual acuity) < 0.5 Age ¡Ã� 18 years Written informed consent obtained from the patient prior to inclusion in the study OR if patient cannot read, written informed consent has been provided by an impartial witness after written or verbal assent from the patient.
