Practising refraction in ophthalmology: instructive or outdated? A prospective study and literature review

Many ophthalmologists preform clinical refactions, although little is known of the perceptions and practise of refraction by ophthalmologists and key barriers preventing this aspect of ophthalmic practice.

Although there are numerous studies on visual acuity in ophthalmology, there is no study to date on the practice of refraction by ophthalmologists. This study evaluates the practice patterns of ophthalmologists in current practice. It specifically addresses perceptions of ophthalmologists about (a) the importance of refraction in clinical practice, and (b) barriers to performing refraction. The methodology and frequency of performing refraction by ophthalmologists is also assessed.

This cross-sectional study was conducted at the Annual Scientific Congress of the Royal Australian and New Zealand College of ophthalmologists in 2017, held in Perth, Australia. All attending ophthalmologists and ophthalmology trainees were invited to participate. Participants completed a 17-variable questionnaire on the perceptions of practitioners about refraction and their practice of it. Data were analysed using Microsoft Excel and IBM SPSS Version 24.

At this Congress, 213 attendees completed the survey, with most being consultant general ophthalmologists (85%). Twenty-six percent of participants either 'really loved' or 'liked' refracting patients. Those who reported feeling competent with refraction were more likely to perform it themselves (p = 0.001). Individuals most commonly reported taking 3-5 minutes to refract a patient (38%). Participants under the age of 65, and participants practising paediatric ophthalmology, were more likely to perform a refraction.

The literature indicates that this is the first study to describe the practice patterns of refraction by ophthalmologists. Although ophthalmologists found refraction important, the majority preferred patients to be refracted by others. Key barriers to ophthalmologists performing refraction included the time required to perform the refraction, a busy clinic, and the availability of alternative providers.
