silicone oil tamponade removal after previous injection of complicated retinal detachment can be achieved with active suction followed by triple air-fluid exchange or prolonged lavage of the vitreous chamber to remove emulsification. Purpose of the study is to compare the amount of silicone oil emulsification droplets within the lavage fluid in case of air exchange and simple lavage to compare which technique removed the highest percentage of emulsion. This is achieved by comparing consecutive samples of lavage fluid
silicone oil tamponade removal after previous injection of complicated retinal detachment can be achieved with active suction followed by triple air-fluid exchange or prolonged lavage of the vitreous chamber to remove emulsification. Purpose of the study is to compare the amount of silicone oil emulsification droplets within the lavage fluid in case of air exchange and simple lavage to compare which technique removed the highest percentage of emulsion. This is achieved by comparing consecutive samples of lavage fluid.
Therefore consecutive patients scheduled to SiO removal with triple air exchange or vitreous chamber lavage are enrolled and 3 samples of intraocular fluid aspirated during the fluid exchange procedure sent to the lab for SiO emulsion count and quantification.

| Measure | Description | Time Frame |
|---|---|---|
| number of silicone oil emulsification droplets per volume unit | number of silicone oil emulsification droplets per volume unit. Fluid taken from the vitreous chamber during surgery is subsequently analyzed. Therefore time frame is just one: after taking all samples they are analyzed to count oil droplets per volume unit | 6 months after primary surgery |
