Central corneal thickness and intraocular pressure in children undergoing congenital cataract surgery: a prospective, longitudinal study

Aim To investigate changes in central corneal thickness (CCT) and intraocular pressure (IOP) in children after congenital cataract surgery, as well as risk factors associated with these changes. Methods 37 eyes of 26 children with congenital cataract undergoing surgery were prospectively recruited. IOP and CCT measurements were performed before the surgery and 6, 12, 18, 24 and 36 months after the procedure. Results Among the 37 eyes, 15 became aphakic and 22 pseudophakic. Mean CCT significantly increased from 556.24 +/- 44.19 to 585.07 +/- 56.45 mu m (p=0.003) after 3 years, whereas mean IOP significantly increased from 12.05 +/- 2.3 to 13.89 +/- 2.96 mm Hg (p=0.037). Aphakic eyes underwent surgery at an early age (15.16 +/- 32.02 months) compared with pseudophakic eyes (71.48 +/- 53.14 months) (p10 years old, respectively (p
