CCT increases after congenital cataract surgery in children

Central corneal thickness increased over time in patients who underwent congenital cataract surgery, with a greater increase occurring in younger patients, according to a study.
The prospective study included 37 eyes of 26 children undergoing congenital cataract surgery. Central corneal thickness (CCT) and IOP were measured preoperatively and at 6, 12, 18, 24 and 36 months postoperatively.
After cataract surgery, 15 eyes were aphakic and 22 were pseudophakic. At 3 years, mean CCT increased from 556.24 μm to 585.07 μm (P = .003) in all eyes. The mean change was 56.10 μm in aphakic eyes vs. 12.71 μm in pseudophakic eyes (P = .015).
CCT change was inversely correlated with age at the time of surgery (P = .04).
Over the 3-year follow-up period, IOP increased significantly from 12.05 to 13.89 mm Hg (P = .037). There was no significant correlation between IOP and CCT change or age at time of surgery.
“Our series suggests that age is probably the most important factor influencing postoperative CCT changes,” the study authors said.
