With the widespread application of laser vision correction in clinical treatment, it has become one of the important treatment methods for the correction of refractive errors, such as myopia and presbyopia, and provides important technical support for the treatment for refractive errors in Chinese adults.At present, continuously improving the visual acuity and quality of life is still the ultimate goal pursued by refractive surgeons.Accurate preoperative refraction and simulation of monocular vision are important procedures to ensure surgical effectiveness, achieve optimal visual quality, and achieve postoperative comfort for patients.However, up to now, there is no prefer practice pattern for refraction in China, standardized preoperative examination or effective consultations with patients before surgery.In order to standardize the preoperative examination for clinical researchers and practitioners engaged in laser vision correction, the Division of Refractive Surgery Branch of Ophthalmology, China National Health Association organized experts to review evidence-based literature nationally and internationally, summarize the clinical problems that need to be solved in clinical practice.After discussion, the experts develop the Expert consensus on preoperative refraction and simulation of monocular vision for laser vision correction in China (2023) and provide recommendations on clinical issues such as subjective refraction, objective refraction, subjective combined with objective refraction, dominant eye evaluation, binocular visual function examination, and monocular vision simulation before laser vision correction.The aim of this consensus is to improve the accuracy of preoperative refraction and monocular vision test for laser vision correction, and to make laser vision correction more standardized, personalized and humanistic in China.
