    PURPOSE: To describe the different characteristics of vitrectomized and nonvitrectomized eyes in phacoemulsification. METHODS: We compare the different characteristics of fluid dynamics in non-, partially, and completely vitrectomized eyes using the Digital Fluoroscopy System. RESULTS: Phacoemulsification in the vitrectomized eye is often more challenging than in the nonvitrectomized eye. Such challenges increase the intraoperative complication rate. However, phacoemulsification can be performed with a low complication rate in the hands of surgeons who well understand the characteristics of the vitrectomized eye. CONCLUSION: Recognizing the differences in the characteristics of the vitrectomized eye reduces the frequency of intraoperative complications.
