    Abstract:
    Our study was performed to investigate the operative effects of pediatric cataract surgery with anterior vitrectomy. The study comprised of 38 pediatric patients aged 2-5 years and involved a total of 60 eyes with congenital cataracts. The study was done between March 2004 and December 2005. Posterior capsulorhexis with anterior vitrectomy was performed on 34 eyes of 20 children, and cataract extraction was performed on 26 eyes of 18 children. The percentages of various complications and rate of neodymium YAG (Nd:YAG) laser capsulotomy were followed up for 12-36 months. There were significant differences in the percentages of posterior capsule opacification (PCO) and rate of neodymium YAG (Nd:YAG) capsulotomy between the anterior vitrectomy group and cataract extraction group (P < 0.01). The anterior vitrectomy group was associated with less posterior capsular opacification (11.8%) than the cataract extraction group (76.9%). The YAG capsulotomy rate was 2.9% for the anterior vitrectomy group, and 57.7% for the cataract extraction group. After operation the fibrous exudates in anterior chamber and the intraocular lens subluxation or capture were 5.9% and 2.9% for the anterior vitrectomy group while for the cataract extraction group they were 23.1% and 15.4%; the difference was statistically significant (P < 0.05). The results suggest that primary posterior capsulorhexis with anterior vitrectomy in pediatric cataract surgery who are between 2 and 5 years old is necessary and effective procedure with low PCO rate.
