| description | Purpose:
To evaluate the prediction error (PE) in pediatric traumatic cataract surgery involving primary or secondary intraocular lens implantation (IOL) and the factors affecting it.
Methods:
Retrospective data of unilateral traumatic cataract eyes of children aged ≤16 years were collected between February 2019 and March 2022 at a tertiary eye care hospital. Absolute PE was calculated by deducting the target refraction from the observed refraction at 6 weeks postsurgery following suture removal. Simulated PE was calculated in eyes with corneal scar replacing the affected eye keratometry (K) with the K of the fellow eye and standard K (44D) and was then compared with absolute PE.
Results:
Fifty children with a mean age of 9.5 years (2–16 years) were included. Mean absolute PE was 1.63 ± 1.8D (0 to 9D). Absolute PE was not affected by the age at surgery, method of biometry, duration of injury, type of cataract surgery, position of IOL, and preoperative keratometry. The absolute PE was affected by axial length (AXL) being <1.5D in AXL of 22.73 ± 0.84 mm, <1.5–2D in AXL of 22.07 ± 0.61 mm, and >2D in AXL of 22.01 ± 0.74 mm (P = 0.039) in univariate analysis. In multivariate analysis, none of the factors affected the absolute PE. In 34 eyes with corneal scar, higher variability in PE was observed. The standard K resulted in greater simulated PE as compared to the affected eye average K in eyes with scar involving the visual axis.
Conclusion:
Absolute PE following pediatric traumatic cataract was studied. It was higher in shorter AXLs. In corneal scar involving the visual axis, using the fellow eye K yielded lesser simulated PE as compared to standard K. |
