2023 Global Survey of Optometry: Defining Variations of Practice, Regulation and Human Resources Between Countries

Abstract

Purpose: To provide information on the demographics of optometrists and regulation of the optometry profession in countries who were members of the World Council of Optometry (WCO) during the period 2022-2023.

Methods: A non-random, purposive sampling and a key informant strategy was employed to conduct a survey-based cross-sectional study on the professional landscape and distribution of optometrists; educational landscape; legislative aspects of the profession; and the scope of optometry practice in countries who were members of WCO during the period 2022-2023. Key informants were identified by WCO country members' leadership.

Results: In the 39 countries surveyed, one optometrist serves 23,200 persons on average. Only 46.2% of the countries met the internationally suggested 1:10,000 optometrist-to-population ratio. The average male-to-female ratio was 45% males/55% females, with a division of average age as follows: under 45 years of age 46% as compared to above 45 years of age 54%. It was reported that optometry is not regulated in France, Portugal, India, Kenya and Cameron. Thirteen countries (33%) do not require a Bachelor's degree as a minimum to practice optometry. Use of diagnostic drugs is prohibited in 20% of the countries, with 25% of the countries limiting the use of therapeutic pharmaceutical agents.

Conclusion: Many countries where optometry is recognized struggle to have an adequate number of optometrists; this hinders access to eye care. This is compounded by unregulated minimum levels of education for entry-level optometric practitioners. In addition, several countries limit or prohibit many optometric procedures that restrict the ability of optometrists to provide eye care and vision health services at the primary care level.
