AIM: To investigate the clinical effects of vitrectomy combined with intravitreal phacoemulsification to treat dislocated lens into the vitreous cavity.

METHODS:Retrospective study of 23 cases patient's data, whose lens were dislocated into the vitreous cavity were treated by vitrectomy combined high-energy(80%-100%), high negative pressure(200-500mmHg)intravitreal phacoemulsification. We observed the best-corrected visual acuity preoperative and postoperative and complications.

RESULTS:Twenty-three cases of dislocated lens into the vitreous were removed successfully by this method, with no surgery-related complications. The mean follow-up period was 18 months. Preoperative best-corrected visual acuity ranged from 3.3 to 4.2, and postoperative best-corrected visual acuity ranged from 3.7 to 4.9. There was a significant difference(t=-11.244, P=0.000).

CONCLUSION:Pars plana vitrectomy combined with intravitreal phacoemulsification to treat dislocated lens into the vitreous cavity is an effective and safe method.
