A follow up study to investigate whether UK optometrists partially prescribe significant changes in refractive correction to assist patient adaptation and whether various aspects of practitioner profiles are linked to the nature of these prescribing decisions.
A case scenario type questionnaire was distributed by post and via the internet to UK optometrists. Five case scenarios were described that included information on patient age, symptoms, habitual refractive correction (if any), subjective refraction and any other relevant clinical information. In each case respondents were asked to indicate and justify what refractive correction they would prescribe.
A total of 592 questionnaires were completed. Between 41% and 84% prescribed the subjective refraction result depending on the scenario. The likelihood of partial prescribing increased by 34% for every 10 years following qualification and thus after a typical 40 year career, respondents were now over three times more likely to partially prescribe. There were no other links with the propensity to partially prescribe.
The subjective refraction result exerted a strong hold on the reported prescribing outcome, particularly for newly qualified optometrists. Partial prescribing was increasingly proposed the greater the number of years the respondent had been qualified. This suggests that with increasing exposure to patients who return dissatisfied with their spectacles, a greater appreciation of partial prescribing is gained. This link seems to be an important finding that provides significant support for the prescribing rules suggested by textbooks, which are not yet supported by research evidence.
一项后续研究旨在调查英国验光师是否部分调整屈光矫正处方以帮助患者适应，以及从业者特征的各个方面是否与这些处方决策的性质有关。
通过邮寄和互联网向英国验光师分发案例情景类型问卷。描述了五个案例情景，包括患者年龄、症状、习惯性屈光矫正（如有）、主观验光和任何其他相关临床信息。在每种情况下，要求受访者表明并证明他们将开出何种屈光矫正处方。
共完成了 592 份问卷。根据情景，有 41%至 84%的人开了主观验光结果。每增加 10 年的资格后，部分处方的可能性增加 34%，因此在典型的 40 年职业生涯后，现在受访者部分处方的可能性增加了三倍多。没有其他与部分处方倾向有关的联系。
主观验光结果对报告的处方结果有很强的影响，特别是对刚获得资格的验光师。随着受访者获得资格的年限增加，部分处方的提议越来越多。这表明，随着越来越多的患者对他们的眼镜不满意而返回，对部分处方的认识也越来越深刻。这种联系似乎是一个重要的发现，为教科书中建议的处方规则提供了重要支持，而这些规则尚未得到研究证据的支持。
