Summary
Pediatric eyes with cataracts show steeper corneal curvature, especially in younger children and unilateral cases. Cataractous eyes in unilateral cases are steeper than their healthy fellow eyes.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Corneal Physiology
Background:
- Pediatric cataracts require careful management, and understanding corneal curvature is crucial for refractive outcomes.
- Keratometry data in pediatric eyes with cataracts is not well-established.
Purpose of the Study:
- To analyze keratometry data in pediatric eyes with cataracts.
- To compare keratometry between unilateral cataractous eyes and their fellow eyes.
Main Methods:
- Retrospective review of preoperative keratometry data from 299 pediatric cataract patients.
- Exclusion of eyes with traumatic cataracts or lens subluxation.
Main Results:
- Average keratometry was 45.39 D. Age and axial length significantly correlated with keratometry (P < .001).
- Younger children (0-6 months) had steeper corneas than older children (P < .001).
- Unilateral cataractous eyes were steeper than their fellow eyes (P = .02).
Conclusions:
- Younger children exhibit steeper corneal curvature compared to older children.
- In unilateral cases, the cataractous eye has a steeper cornea than the non-cataractous fellow eye.
