Summary

Intraocular lens (IOL) implantation effectively rehabilitates vision in children younger than 4 years with unilateral aphakia. This study shows good visual outcomes and manageable complications in pediatric pseudophakia.

Area of Science:

  • Ophthalmology
  • Pediatric Surgery

Background:

  • Unilateral aphakia in young children presents challenges for visual development.
  • Early visual rehabilitation is crucial to prevent amblyopia and strabismus.

Purpose of the Study:

  • To evaluate the efficacy of intraocular lens (IOL) implantation for visual rehabilitation in children under 4 years with unilateral aphakia.
  • To assess visual outcomes, refractive changes, and complications following IOL implantation in this pediatric population.

Main Methods:

  • Retrospective analysis of 21 patients undergoing unilateral cataract extraction and IOL placement.
  • Patients were divided into infantile (n=12) and posttraumatic (n=9) cataract subgroups.
  • Prospective monitoring of postoperative vision, refractive error, and complications.

Main Results:

  • 52% of patients achieved 20/40 or better vision, with higher success in the traumatic cataract group (67%).
  • Refractive outcomes were generally accurate, though a progressive myopic shift was observed over time, particularly in the infantile group.
  • Complications included IOL dislocation, corectopia, and pupillary capture; strabismus surgery was required in 6 patients.

Conclusions:

  • Primary intraocular lens implantation is an effective strategy for rapid visual rehabilitation in preschool children with unilateral aphakia.
  • Long-term safety and effects of pediatric pseudophakia require ongoing evaluation.
