Abstract

PURPOSE: To evaluate surgical results and complications of different intraocular lenses (IOL) implantation in pediatric cataract surgery.
METHODS
We retrospectively reviewed 139 eyes of 80 patients who had undergone irrigation and aspiration of cataracts and primary posterior chamber intraocular lens implantation with posterior continuous curvilinear capsulorhexis and optic capture from July 1998 to December 2005. All the eyes were divided into three groups into the intraocular lenses implanated: group 1 (n=40), PMMA lens was implantated; group 2 (n=42), hydrophobic acrylic lens was implantated; group 3 (n=57), hydrophilic acrylic lens was implanated. The surgical results and complications was evaluated.
RESULTS
Wound leakage, iris prolapse, shallow anterior chamber during operation were the most common in group 1. Peripheral anterior synechiae, conjuntival cyst, pigment deposition of IOL, exudative membrane, elevated intraocular pressure were also the most common in group 1 (P<0.05). There was no statistically significant defference in the prevalence of intraoperative and postoperative complications between group 2 and 3. Postoperative final visual acuity and astigmatism were not significantly different between the three groups.
CONCLUSIONS
Implantation of hydrophilic acrylic IOLs, as well as hydrophobic acrylic IOLs decrease complications and have good surgical results compared to PMMA IOLs in pediatric cataract surgery.

  • Figure 1. Distribution of implanted intraocular lenses. Before the year 2000, most eyes were implanted with PMMA intraocular lens, but afterward hydrophilic and hydrophobic acrylic intraocular lenses were implanted.
