Purpose: To evaluate the rate of myopic shift during 3.5 years in children with pseudophakia at a tertiary eye care hospital. Materials and Methods: A retrospective review of the medical records was conducted for children aged 1-9 years who underwent cataract extraction with intraocular lens (IOL) implantation in order to evaluate initial and annual postoperative refractions. Adjusted estimates of the rate of refractive shift related to patient characteristics were based on a generalized estimating equation model of spherical equivalent refractive error over time, taking into account time-related correlations within the data. Results: A total of 138 eyes of 117 subjects were included in the study. A statistically significant shift in refractive error over time was found in the myopic direction (P < 0.001) Significant interaction was present, indicating that age at time of surgery influenced the rate of myopic shift, but only in children with traumatic etiology. A myopic shift of -0.66 diopters/year was calculated in patients with cataracts of nontraumatic etiology. In those with traumatic cataracts, the rate of myopic shift was -0.85 diopters/year, with a decrease 0.13 diopters/year for each year of increasing age at time of surgery. Conclusion: Our findings suggest a trend toward myopia in pseudophakic children. This was particularly true in children with cataracts of traumatic origin. The strategy of aiming for a hyperopia in order to offset some of the expected myopia may be a reasonable one. Further work is required to develop the necessary nomograms. |
