[Can vitrectomy without use of microscissors improve results of surgery for proliferative diabetic retinopathy?]

In order to test the hypothesis that in proliferative diabetic retinopathy surgery the vitrectomy without the use of microscissors could improve the results and decrease the rate of complications as well as the operating time, two groups are compared in a consecutive series of 24 eyes, operated on with or without scissors, and with a minimum follow-up of 6 months. The study shows that the vitrectomy without scissors offers a higher percentage of eyes with a postoperative visual acuity at least two lines better than the preoperative visual acuity. It shows also a trend for a shorter surgery, with fewer complications in case of vitrectomy without scissors.
