IAPB Essential List: Low Vision

The Essential Lists:

Version: First Edition (March 2017)

Why is this list important?

Despite major advances in eye care, an estimated 124 million people worldwide cannot have their sight fully restored with standard corrective measures. These people are regarded as having low vision. The majority of them, about 80 million people, however, have some residual vision that can be enhanced with special intervention: rehabilitation strategies, optical and non-optical devices, all of which can be utilized to assist them to carry out tasks that require vision.

What does this list contain?

This list provides recommendations for Instrumentation, Equipment and Low Vision Optical Devices and Assistive Devices for people with low vision. These are classified as desirable (D) or essential (E) across all three levels of service: primary (PRIM), secondary (SEC) and Tertiary (TER). See Figure 1.

How can quantities be calculated?

Suggested quantities are calculated for:

  • Equipment and instrumentation used for assessment of visual acuity and vision function1
  • Optical and assistive low vision devices used for assessment of vision/functionality. These are also issued or dispensed to patients.

The bracketed code after each number2 indicates that for any given clinic the device is likely to be issued to Many—20 or more (M), Some–10 or more (S) or a Few—5 or more (F) patients, relative to overall patient throughput3.

Three-tier model of care

Figure 1: This list is based on a three-tier model of care: Personnel at primary, secondary and tertiary level, able to refer appropriately for that level, both vertically for eye care services and horizontally to other service providers.

  • All Desirable (D) or Essential (E) items at a PRIMARY LEVEL will be Essential at all SECONDARY LEVEL or TERTIARY LEVEL
  • All Desirable (D) items at a SECONDARY LEVEL will be Essential (E) at TERTIARY LEVEL
