Abstract

Introduction: An assessment done by the WHO found cataracts accounted for 51% of the causes of global blindness and 33% of visual impairment, inclusive of blindness.1 The Nigerian National Blindness and visual impairment survey 2005 to 2007 found that 42.9% of blindness was due to cataract.2

Methods: Study design: Retrospective study of individuals that had undergone manual small incision cataract surgery (MSICS) at the Eye Center. Axial length measurements were performed using the IOLMaster (Carl Zeiss Meditec AG, Jena, Germany). Those cataracts too dense to have proper biometry using the IOLMaster had A scan done using the Quantel medical Axis II (Quantel Medical, France) and Keratometry readings were done using the Topcon Autokeratorefractometer KR-8900 (Topcon Corporation, Tokyo, Japan). Various formulas were used to determine the IOL power depending on the axial lengths; Hoffer Q (for axial lengths <22), Holladay, Hoffer Q, SRK-T (for axial lengths 22.0-24.5), Holladay (for axial lengths 24.5-26) and SRK-T (for axial lengths >26.0). Six Ophthalmologists trained in manual small incision cataract surgery performed the surgeries.
