Managing Cataracts in Microcornea

Overview

A multicenter Japanese study indicates that congenital cataract surgery in infants with microcornea can yield long-term visual outcomes, although challenges such as postoperative glaucoma and visual axis opacification persist.

Background

Microcornea is a rare congenital condition characterized by a corneal diameter of less than 10 mm, complicating pediatric cataract management due to limited anterior segment anatomy and associated ocular anomalies.

Data Highlights

ParameterBilateral Pseudophakic EyesBilateral Aphakic Eyes
Mean Age at Surgery3.3 months3.3 months
Follow-up Duration13.7 years13.7 years
CDVA 20/40 or Better88%39%
Secondary Glaucoma0%18.8%

Key Findings

  • Bilateral pseudophakic eyes achieved 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 experienced glaucoma during follow-up.
  • All groups experienced substantial myopic shifts over time.

Clinical Implications

Clinicians should be aware of the potential for secondary glaucoma and myopic shifts in this patient population.

Conclusion

This study provides insights into the management of congenital cataracts in infants with microcornea.
