Abstract Details

Purpose:

To understand the effect of intraocular lens (IOL) materials on visual outcome and related complications in patients with posterior capsular (PC) rupture during phacoemulsification.

Setting:

Retrospective, case-control study Chang Gung Memorial Hospital

Methods:

The inclusion criteria were PC rupture and primary implantation of acrylic or silicon IOL, while exclusion criteria were pre-existing ocular diseases, previous ocular surgery, intraoperative complications other than PC rupture, and follow-ups less than six months. Main outcome measurements were postoperative best corrected visual acuity (BCVA) at three time points (week 1, month 1, and month 6).

Results:

PC rupture occurred in 100 out of 2495 patients (4%). After excluding three patients, 47 received acrylic (n = 47) and 50 silicon IOL. Another 45 cases without PC rupture were selected as a control. Postoperative BCVA was not different between the acrylic IOL and control groups, while vision was worse in the silicon IOL group (p<.01). Additionally, stable BCVA was achieved one month postoperatively in the acrylic group, but not until six months in the silicon group. Complications likes corneal edema or IOP elevation in the acrylic and silicon IOL groups were both higher than the control group (p=.03).

Conclusions:

For phacoemulsification patients complicated by PC rupture, faster recovery and better results of BCVA are achieved with acrylic than silicon IOL, while complication rates are similar.
