To compare intraocular pressure (IOP) control before and during the first year after secondary intraocular lens (IOL) implantation in children.
This was a retrospective chart review of children who received secondary IOL implantation. We analyzed IOP and antiglaucoma medications before and after implantation. The latest exam with IOP measurement found within the 2-15 month period after IOL implantation was used for the postoperative data. Failure to maintain IOP control was defined as either the addition of antiglaucoma medication(s) or a rise in IOP > 4 mm Hg. Statistical analyses were performed to assess risk factors for failure to control IOP after surgery, namely age at IOL implantation, preoperative glaucoma status, and IOL fixation location.
A total of 100 eyes were included. The mean duration of follow-up was 7.74 months (SD = 3.11). Twenty-three of one hundred eyes failed to maintain IOP control according to our definition. Eyes with a history of having had a traumatic cataract (n = 3) had a more than threefold increased risk of failure (P = 0.015). Although not statistically significant, very young age at initial cataract surgery (12 months old) (P = 0.213). No other risk factors were found to have statistical significance.
Secondary IOL implantation carries a modest risk of worsening IOP control in the first year after implantation, for which, a history of ocular trauma or young age at initial cataract surgery seems to present the highest risk.
