And yet, there are more than 100 million people around the world who are visually impaired because of a lack of pair of spectacles. In this week, we will look at what is required in order to detect and manage these refractive errors. Provision of refractive error services should ideally be within a health system. And yet, it also has to be balanced with what is the acceptance by both the individual and the community. In this week, Professor Clare Gilbert shares her views on the models and the challenges of refractive error service provision.

Welcome to Week 4

Welcome to the fourth week of the course. If you want to revisit material from previous weeks, you can navigate through them via the ‘to do’ list. Click ‘To do’ and select the appropriate week.

This week we will look at our third course objective, to evaluate the key disease public health control strategies to strengthen service provision for refractive error in a local setting. We will look at available control strategies for refractive error in detail.

By the end of the week you should be able to:

  1. Define refractive errors and their epidemiology
  2. Relate to the challenges and opportunities in service delivery for refractive error
  3. Appraise the concept of school health programme for refractive error
  4. Define presbyopia and its epidemiology
  5. Relate to the challenges in service delivery for presbyopia
  6. Assess optical service delivery and its alignments with health systems.
