Overcoming myopic shift by the initial inductive hypermetropia in pediatric cataract surgery

Purpose: To assess the outcome of under-correction of intraocular lens (IOL) power in pediatric cataract surgery. Methods: We collected clinical data of 103 patients (181 eyes), all aged ≤15 years, who had undergone cataract surgery by a surgeon during 2006–2016. The mean duration of follow-up was 73 ± 38 months (range: 24–108). IOL power was calculated by Hoffer Q formula in axial length (AL) 10 years old. Results: The mean age of all children at surgery time was 5.85 ± 4.56 years (range: 1–178 months). There was a mean myopic shift of −6.379 D in the ≤1 year, −5.532 in the 1–3, −3.194 in the 3–5, −2.301 in the 5–7, −1.06 in the 7–9, −1.567 in the 9–10, and 0.114 in the >10-year-old age group. In 125 eyes (69.1%) of 181, the final SE was between −2 and +2 D, and 21 eyes (11.6%) achieved the goal of emmetropization. Mean best-corrected visual acuity logarithm of the minimum angle of the resolution was 0.30 in children ≤1 year, 0.39 in 1–3, 0.21 in 3–5, 0.18 in 5–7, 0.14 in 7–9, 0.16 in 9–10, and 0.11 in children >10 years old. Conclusion: This study shows a larger myopic shift in younger children. Using our approach, all age groups could finally achieve acceptable final refraction.
