Ey. Yap et Wj. Heng, Visual outcome and complications after posterior capsule rupture during phacoemulsification surgery, INT OPHTHAL, 23(1), 1999, pp. 57-60
Purpose: To determine the visual outcome and incidence of complications aft
er posterior capsule rupture during phacoemulsification surgery. Methods: F
orty-four eyes of 43 patients which sustained posterior capsule rupture or
zonulysis during phacoemulsification surgery between April 1993 and May 199
6 were retrospectively studied. Eyes With pseudoexfoliation syndrome, traum
atic cataract and myopia > 6 dioptres were excluded from the study. The mea
n postoperative follow-up period was 26 months (range 3 to 47 months). Resu
lts: Forty-one eyes had posterior capsule rupture and 3 eyes had zonulysis.
Of these 44 eyes, 41 eyes had vitreous loss and anterior vitrectomy at the
time of surgery or subsequently. Excluding 2 eyes with pre-existing condit
ions that precluded good vision, 36 out of 42 eyes (85.7%) achieved spectac
le corrected visual acuity of 6/12 or better post-operatively. Of all 42 ey
es, 20 had anterior chamber intraocular lens (ACIOL) implantation while the
others had posterior chamber intraocular lens (PCIOL) implantation. For ey
es with ACIOL, 17 out of 20 eyes (85.0%) had best corrected visual acuity o
f 6/12 or better. For eyes with PCIOL, 19 out of 22 eyes (86.4%) had best c
orrected visual1 acuity of 6/12 or better. Conclusions: Phacoemulsification
surgery, even if complicated by posterior capsule rupture or zonulysis, is
compatible with good visual outcome. This is provided prompt attention is
paid to the management of complications.
