Alcon Advanced Ultravit High-Speed Vitrectomy Probe
On the day of surgery, patients will be randomized to the Ultravit High-Speed Beveled Probe or the current non-beveled Alcon Probe. All patients will undergo routine vitrectomy surgery as scheduled; patients will be unaware of the vitrector probe used. Time to completion of vitrectomy and time to completion of vitreous base shave will be recorded by study staff unaware of the vitrector probe used. All examination will be repeated as regularly scheduled postoperative visits by a reader unaware of which probe was used. Safety will be assessed at each visit by evaluation for any adverse events.

Alcon Non-Beveled Tip Vitrectomy Probe
On the day of surgery, patients will be randomized to the Ultravit High-Speed Beveled Probe or the current non-beveled Alcon Probe. All patients will undergo routine vitrectomy surgery as scheduled; patients will be unaware of the vitrector probe used. Time to completion of vitrectomy and time to completion of vitreous base shave will be recorded by study staff unaware of the vitrector probe used. All examination will be repeated as regularly scheduled postoperative visits by a reader unaware of which probe was used. Safety will be assessed at each visit by evaluation for any adverse events.
