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.
