ABSTRACT
PURPOSE:
To evaluate the refractive outcomes using 5 different IOL power calculation formulas (SRK II, Holladay I, Hoffer Q, SRK T, Binkhorst II) in pediatric cataract patients.METHODS:
A retrospective analysis of biometric and refractive data was performed on 63 eyes of 44 pediatric patients, who successfully underwent primary and secondary IOL implantation. For analysis, the eyes were divided into three groups those with axial length or =22 mm but or =24.5 (group L). And also divided into another three groups those with mean keratomery value or =42.5D but or =44.5D (group III). The postoperative refractive outcome was taken as a spherical equivalent of the refraction at 1 week and 2 to 3 months after surgery. The 'predictive error' was defined as absolute error between the target and actual postoperative refraction.RESULTS:
SRK II had a best predictive error but there was no statically significant in short eye group and medium eye group at 1 week and 2 to 3 months after the surgery. And SRK II also had a best predictive error but there was no statically significant in group I, II, and III at 1 week and 2 to 3 months.CONCLUSIONS:
In our study, theoretical formulas did not outperform the regression formula in pediatric IOL implantation. This may be related to the variability of the relationship between axial length and corneal curvature in pediatric eyes and to dependent variables inherited in the formulas.
