Identification and critical appraisal of evidence for interventions for refractive error to support the development of the WHO package of eye care interventions: a systematic review of clinical practice guidelines.

Current high-quality guidelines on refractive error have been formulated in high-income countries. Recommendations focused on prevention and treatment of refractive error in low-and middle-income countries are lacking. Regular updating of systematic reviews and CPGs is essential to ensure that robust evidence is promptly appraised and incorporated into recommendations for eye health care practitioners.
