Long-term longitudinal assessment of postoperative outcomes after congenital cataract surgery in children with congenital rubella syndrome.

PURPOSE: To assess the intraoperative and long-term longitudinal postoperative outcomes of cataract surgery in children with congenital rubella syndrome.

SETTING

Iladevi Cataract & IOL Research Centre, Ahmedabad, India.

DESIGN

Prospective observational clinical study.

METHODS

Children with congenital rubella syndrome who had cataract surgery were enrolled. All microphthalmic eyes were left aphakic. A 1-piece hydrophobic acrylic intraocular lens was implanted in the capsular bag in eyes without microphthalmos. The postoperative observations included complications and visual assessments up to 5 years.

RESULTS

The mean age of the 21 children (37 eyes) was 3.97 months ± 2.1 (SD). Intraocular lens implantation was performed in 12 eyes (32.4%), while 25 eyes (67.6%) were left aphakic. Postoperatively, the median follow-up was 60.79 months. Posterior synechiae were observed in 22 eyes (59.5%) and visual axis opacification in 9 eyes (24.3%). Secondary glaucoma was observed in 16 eyes (43.2%), of which 14 were aphakic and 1 was pseudophakic. Nine eyes required trabeculectomy. Age at surgery and ocular comorbidities were statistically significantly associated with secondary glaucoma (P<.05, χ(2) test and Kendall τB criteria P<.05). The mean corrected distance visual acuity at the final follow-up was 0.72 ± 0.56 logMAR.

CONCLUSIONS

The long-term results suggest good visual outcomes can be obtained with congenital cataract associated with congenital rubella syndrome after early surgical intervention. The rate of serious postoperative complications was acceptable.
