Abstract Details


The purpose of the present study was to assess the distribution of ocular biometric parameters measured with the IOLMaster 700 in school-children.


Poostchi Eye Clinic; Shiraz, Iran.


Our study is a part of a cross‑sectional population-based study conducted from September 2015 to March 2016 in Shiraz, Iran. A total number of 2400 eligible children aged between 6 to 12 years were enrolled. Of this population, 596 individuals had undergone ocular biometry using IOLMaster 700. Age and sex specific distributions of ocular biometric parameters were provided.


In this population, the mean value of the mean keratometry was 43.78 +- 1.52 D in the right eyes and 43.82 +- 1.50 D in the left eyes. The mean of astigmatic keratometry was 1.11 +- 0.69 D and 1.12 +- 0.69 D, in the right and left eyes, respectively. The average axial length was 22.83 +- 0.79 mm in the right eyes and 22.81 +- 0.79 D in the left eyes. There was no significant difference between fellow eyes or between boys and girls in any ocular biometry parameter.


This study provided a reference for the mean values and standard range of ocular biometry parameters for Iranian school-children aged 6 to 12 years. Comparing with Chinese and American children, our data showed lower values for most biometric parameters.
