Uncorrected Refractive Errors

Convenors: Kovin Naidoo and Hasan Minto
GOC for Optometrists GOC for Dispensing Opticians

This course is sponsored by the Brien Holden Vision Institute, our 10GA Programme Partner. Programme Partners are NGOs (IAPB members) who will host and run a full, listed session which will be part of the scientific programme, in collaboration with the Scientific Programme committee. IAPB thanks them for their support.


Globally 285 million people are visually impaired. Of these, 107.8 million have uncorrected distance refractive error. In addition, there are 517 million people with near vision impairment due to uncorrected presbyopia. The prevalence of refractive error, such as myopia, is rapidly increasing, particularly in Asia Pacific where in countries like China around 50% of population has myopia which translates into > 600 million people. Over 80% are visually impaired due to treatable or curable causes. Over 90% of this demographic resides in lower or middle income countries. The financial burden on economy due to uncorrected distance and near refractive error is ≥ US$227.36 billion. While the estimated cost of correction of distance vision is between US$20 billion and US$28 billion. The World Health Organization has recently released the global burden of disease data and for the first time has recognized vision impairment due to uncorrected refractive error as a cause of disability. According to 2014 figures, 200 million people need glasses or low vision devices and don’t have access to them.

This alarming situation is because of multiple factors. In many cases the number of competent heath care professionals is very few, productivity is low and there is an uneven distribution of resources. In general, the poorest and most remote areas have the least access to eye care. Conditions like cataract, refractive error, diabetic retinopathy and glaucoma have a gradual onset. Due to a lack of access to primary eye care people try to self-medicate or use coping strategies. These lead to complications or even complete vision loss. For these reasons it is imperative that refractive care is fully integrated into public health initiatives.
