Purpose
The aim of the present study is to compare the functional and clinical differences and advantages between a standard operating system and a newly developed even smaller system for pars plana vitrectomy.
The present study may work out the possible advantages and disadvantages between the routinely used 20-gauge vitrectomy system and the newly developed 23-gauge device.

| Enrollment: | 60 |
| Study Start Date: | September 2004 |
| Study Completion Date: | October 2007 |
60 patient randomized into 2 groups of 30 each. All of them operated in general anesthesia, vitrectomized and cataract extracted by phacoemulsification if indicated. Preoperative and postoper5ative controls at days 1,2,3 and week 1, month 1,3 and 12 performed. Parameters of interest are: postoperative conjunctival injection, pain, eye pressure, complications intra- and postoperative as well as the durations of surgery divided into opening time, vitrectomy time, retinal manipulation time, closing time.
