Managing Cataracts in Microcornea
Long-term outcomes encouraging in congenital cataract infants with microcornea, says Japanese study
Objective:
To evaluate long-term visual outcomes of congenital cataract surgery in infants with microcornea.
Approach:
Key Findings:
- Bilateral pseudophakic eyes achieved significantly better corrected distance visual acuity (CDVA) compared to bilateral aphakic eyes.
- 88% of bilateral pseudophakic eyes achieved 20/40 vision or better, versus 39% in bilateral aphakic eyes.
- Secondary glaucoma developed in 18.8% of aphakic eyes, while no pseudophakic eyes developed glaucoma during follow-up.
- All groups experienced substantial myopic shifts over time.
- Postoperative glaucoma and visual axis opacification remain significant management challenges.
Interpretation:
The study highlights the need for careful management of complications and refractive changes in infants with microcornea.
Limitations:
- Retrospective design and relatively small subgroup sizes limit definitive conclusions.
- Selection bias may have influenced outcomes as only patients with at least 10 years of follow-up were included.
Conclusion:
The findings provide long-term insight into managing cataracts in microcornea and support the feasibility of primary IOL implantation.
