Phacoemulsification on previously vitrectomized eyes: results of a 10-year-period.
OBJECTIVE
To provide an overview of intraoperative and postoperative complications during phacoemulsification cataract surgery and to evaluate the visual results in patients having pars plana vitrectomy (PPV) with 10 years of follow-up.


METHODS
Retrospective evaluation of intraoperative and postoperative complications and postoperative visual results in 134 consecutive patients who underwent phacoemulsification after PPV. Of 11,498 eyes treated with phacoemulsification, 143 (1.2%) had previous PPV during the 10-year period were included in this study.


RESULTS
The phacoemulsification procedure seemed to be difficult where there was a deep or fluctuating anterior chamber (93%) and primary posterior capsule opacification (19%). The most frequent intraoperative complications were posterior capsule rupture (9%) and incomplete capsular rhexis (5%). Postoperative intraocular pressure elevation (7%), retinal detachment (6%), and posterior capsule opacification (8%) occurred most frequently during the mean follow-up period of 18.2 months (1.5-110 months). Best-corrected visual acuity (BCVA) increased two or more Snellen E lines in 55% of the cases or became better than or equal to 0.5 in 10% of the cases.


CONCLUSIONS
Despite the well-known difficulties encountered in vitrectomized eyes such as zonular damage, increased mobility of the lens-iris diaphragm, and altered intraocular fluid dynamics, phacoemulsification proved to be a safe procedure in the hands of experienced surgeons.
