An Interocular Comparative Study of Unilateral Cataract

Great advances have been made in managing pediatric cataracts during the last several decades; these advances have contributed to a decrease in the incidence of postoperative complications and improvement in visual outcomes.Early cataract removal and replacement with an intraocular lens (IOL) represent the most appropriate treatments to avoid irreversible amblyopia.Although screening and timely surgical intervention play a key role in improved best corrected visual acuity (BCVA) among pediatric patients with cataracts, determining the prognosis for an individual remains difficult, particularly for unilateral cataract.

Few studies have focused on the interocular differences in ocular anatomic parameters other than axial length in unilateral pediatric cataract after surgery, the significance of which for the possible interocular visual functional difference remains unclear. Therefore, the investigators conducted this cross-sectional study to compare bilateral anterior segment parameters, macular thickness, and BCVA at 3 months after uncomplicated unilateral pediatric cataract extraction with primary IOL implantation to explore any possible interocular differences and their possible relationships.
