Central corneal thickness (CCT) in children with congenital cataracts is influenced by the type of cataract, particularly those with rare morphologies, and increases slightly after cataract surgery, according to a study.
Researchers analyzed 62 eyes from 39 patients who had CCT measured before and after surgery.
Although CCT was not significantly different between bilateral and unilateral cataracts or between operated and fellow eyes, certain cataract types had a notable impact. Eyes with cataracts classified as “other” morphologies, including aculeiform, calcific, cortical, lamellar, pulverulent, and membranous types, had significantly thicker corneas preoperatively than the control group.
The study also found that preoperative CCT tended to decrease with age, while postoperative CCT increased significantly following surgery.
