Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The medical records of 393 eyes of 326 patients with severe proliferative diabetic retinopathy were reviewed. Higher cutting rate instruments (5000 cut per minute) were used in 174 eyes and conventional instruments in 219 eyes (2500 cut per minute). The visual outcome and incidences of intraoperative and postoperative complications were compared.
