Comparison of optical biometry based on partial coherence laser interferometry (PCLI) principle to conventional applanation ultrasonic biometry
Journal Title: Indian Journal of Clinical and Experimental Ophthalmology - Year 2018, Vol 4, Issue 3
Abstract
Purpose Our aim was to compare the accuracy of intraocular lens IOL power calculation with two techniques namely optical biometry based on partial coherence laser interferometry PCLI principle and conventional ultrasound biometryMaterials and Methods A comparative study was done in our hospital wherein 100 eyes of 100 patients undergoing phacoemulsification cataract surgery were recruited into it Out of them 50 eyes underwent optical biometry and 50 eyes underwent conventional applanation ultrasound biometry Eyes were grouped according to axial length into long 2450 normal 22 to Results The MAE calculated was 060 040D and 020 030D with the conventional applanation ultrasound and optical biometry respectively It was found that the optical biometry gives more accurate values for eyeball with small and large axial lengthConclusion The optical biometry parameters which uses the partial coherence laser interferometry PCLI principle happens to be the more precise method in IOL power calculationKeywords Axial length Optical Partial coherence laser interferometry Ultrasound A scan
