文摘

To evaluate long-term follow-up results of pediatric cataract surgery using the bag-in-the-lens (BIL) intraocular lens (IOL) implantation technique.

Setting

Antwerp University Hospital, Edegem, Antwerp, Belgium.

Design

Prospective case series.

Methods

All pediatric cataract surgeries with BIL IOL implantation performed at the Antwerp University Hospital were evaluated. Only cases that completed a follow-up of 5 years at the hospital's Department of Ophthalmology were included in this study.

Results

Forty-six eyes of 31 children had a complete follow-up of 5 years or more after BIL IOL implantation. Sixteen cases were unilateral and 15 were bilateral. Patient age at time of surgery ranged from 2 months to 14 years. The mean refraction at the end of follow-up was −1.99 diopters (D) ± 3.70 (SD). In bilateral cases, a corrected distance visual acuity (CDVA) of better than 0.5 was attained in 86.7% and a CDVA of 1.0 was achieved in 56.7%. In unilateral cases, 31.2% achieved a CDVA of better than 0.5 but none obtained a CDVA of 1.0. A clear visual axis was maintained in 91.3% of cases during follow-up. Visual axis reopacification was detected in 4 eyes of 3 cases, all due to inadequate BIL IOL positioning. None of these eyes needed more than 1 intervention to maintain visual axis clarity. Other than 1 case of glaucoma, no severe complications were detected.

Conclusion

Long-term follow-up results show that BIL IOL implantation is a safe, well-tolerated approach for treating pediatric cataract with a very low rate of visual axis reopacification and a low rate of secondary interventions for other postoperative complications.
