Use Of Extended Range Of Vision Intraocular Lens In Pediatric Cataract Surgery

To evaluate safety and eligibility of extended range of vision (EDOF) intraocular lens (IOL) in pediatric cataract surgery to reduce spectacle dependency after cataract operation.

Visually disturbing bilateral cataract was operated in 34 eyes of seventeen children (9 - 18 yrs, median 14 yrs). EDOF-IOL (Tecnis SymfonyÒ) was implanted in all eyes, 18 spheric (ZXR) and 16 toric IOLs (ZXT) were used. Patients were followed prospectively at 1 month, 6 months (14 patients) and 1 year (10 patients).

Preoperative best corrected monocular distance visual acuity (BCDVA, Snellen values) was 0.37+0.14, and increased to 0.87+0.17, 0.93+0.14 and 0.87+0.18 at 1, 6 and 12 months, respectively. Binocular uncorrected distance visual acuities were 0.86 + 0.23, 0.92 + 0.18 and 0.95 + 0.14 at 1, 6 and 12 months postoperatively, respectively. Binocular uncorrected near visual acuity was 0.54 + 0.17 (range 0.4 – 0.8) at 12 months. At 12 months none of the patients reports dysphotopsias. Five patients reported not to wear any spectacles, two patients used spectacles for reading always and three occasionally, at 12 months.

EDOF-IOLs were safely implanted in 9-18 years old children. Both binocular uncorrected distance and near visual acuities were good and gave high spectacle independency with good eligibility and low number of dysphotopsias.
