Abstract

Objective. To determine refractive changes in children post-cataract extraction and intraocular lens (IOL) implantation at a Philippine tertiary hospital.

Methods. This is a retrospective cohort study involving patients aged 1 to 10 years in the Department of Ophthalmology of a Philippine tertiary hospital who underwent cataract extraction and IOL implantation between 2004 to 2013.

Results. We included 55 eyes of 34 patients in the analysis. Thirty-eight eyes (69%) eyes underwent primary IOL implantation. The mean duration of follow-up was 3.5 ± 2.1 years. The median refractive changes were -2.00 (-2.50, -0.50) diopters (D) for the 1- to 3-year-old group, -1.25 (-1.50, -0.25) D for the 4- to 7-year-old group, and -1.00 (-1.63, -0.25) D for the 8- to 10-year-old group. Only the 1- to 3-year-old group had significant difference between the initial post-operative refraction and the latest follow-up refraction (p<0.001). For the primary implantation group, patients in the 1- to 3-year-old group had the highest median refractive change at -2.00 (-3.125, -1.00) D while patients in the 8- to 10-year-old group had the highest median refractive change at -2.12 (-2.56, -1.69) D in the secondary implantation group. Refractions of eyes with IOL-implanted and normal eyes showed a median difference of -1.00 (-0.25, -3.5) D.

Conclusion. The determination of the power of IOL implants in pediatric patients who underwent cataract extraction remains challenging despite availability of recommendations.
