 Hello and welcome to week 5. To eliminate avoidable blindness, we need to consider change in our approach to service delivery for eye care. This change has to be planned and in this week we'll be looking at some simple logical steps that can be applied to planning. We will use a range of methods and tools to assess what is the present situation, what can and must be changed and finally how can we set appropriate aims and objectives. These planning principles are not specific to eye care and can be used across a range of activities and projects.
