Objective: A retrospective study was undertaken to evaluate long-term anatomic and visual outcomes in eyes of children who underwent bilateral intraocular lens implantation.
Design: The study design was a review of medical records of 24 children operated on for bilateral cataracts and posterior chamber-intraocular lenses.
Participants: Twenty-four children operated on for bilateral cataracts by 1 surgeon between February 1980 and February 1995 were studied.
Intervention: Cataract extraction with bilateral posterior chamber-intraocular lens implantation was performed.
Main outcome measures: Best-corrected visual acuity, visual acuity without correction, intraocular pressure, manifest refraction, and any intraoperative or postoperative complications were measured.
Results: At last follow-up (mean follow-up, 50.8 months; range, 10-149 months), the intraocular lens was in good position and the intraocular pressure was normal without medication in all eyes. Four years after surgery, 79.2% (19 of 24) of first eyes achieved a best-corrected visual acuity of 20/40 or better compared to 66.7% (16 of 24) of second eyes. No eye had any loss in best-corrected visual acuity. In first eyes of 3- to 8-year olds at the time of surgery, 73.3% (11 of 15) achieved a spherical equivalent within 2 diopters of the intended at 4 years after surgery compared to 80% of second eyes. In the 9- to 18-year-old group, 88.9% (8 of 9) of first eyes and 100% of second eyes achieved a spherical equivalent within 2 diopters of the intended at 4 years after surgery. Intraoperative and postoperative complications were minimal.
Conclusions: Long-term anatomic and visual results have been gratifying in this series of patients with bilateral implants.
