Abstract Details

Purpose:

To Validate IOL power using Optiwave Refractive Analysis (ORA) system & compare it with conventional IOL power calculation methods

Setting:

Place of Study – Dr. Rajendra Prasad Centre for Ophthalmic Sciences,AIIMS Hypothesis : IOL power calculation using ORA system is non inferior as compared to conventional methods.

Methods:

Observational comparative studyPrimary outcomes- Residual refractive error & prediction error using ORA as well as conventional IOL power calculation methods & their comparison To compare residual refractive error in different axial length groups(22-24.5;24.5-26;>26) using ORA vs conventional methods.

Results:

IOLMaster & ORA predicted same IOL power in 87% of the cases. SRK II & IOLMaster predicted same IOL power in 69% of the cases. SRK II & IOLMaster predicted same IOL power in 59% of the cases. Significant difference(p value-<0.05) between mean IOL power calculated by SRK II & other two methods(ORA & IOLMaster) No significant difference(p value->0.05) between mean IOL power calculated by ORA & IOLMaster

Conclusions:

ORA is non inferior to conventional methods of IOL power calculation in all axial lengths
