Abstract

This study aims to propose a standardized IOL Power that could be extrapolated to the general popula tion who do not benefit from kerato-biometry and IOL power calculation during surgery. This observation al study was over two years and included 216 eyes of 216 patients, regardless of sex, aged over 39, all of whom had undergone age-related cataract surgery. An association was sought between socio-epidemi ological variables and mean values for keratometry, axial length, anterior chamber depth and intraocular implant power. Statistical analysis was carried out using Epi Info 7.2 Software. Correlations between the ocular biometric parameters and the mean age were analysed with the Person test for a p-value < 0.05. The study revealed that means values of Keratometry was 44.7+/-2.2 D, Anterior chamber dept 3.2+/- 0.5mm ; axial lengh 23.4+/-1.0 mm and IOL Power 21.0+/-2.0 D. A significant association was found between gen der and mean values for keratometry, biometry and IOL power (p=0.001). These values could serve as a reference for many centers in the country and during surgery campaigns for the Guinean population.
