		        	Abstract:
			       	
			       		
				        
				        	To explore an easily executive and conveniently generalized method with effectiveness and low costing for myopia screening at the early stage.Research was performed to testify the reasonability of using axial length/corneal radius (AL/CR) for myopia screening in children by comparing the cost between AL/CR plus vision acuity (VA) and simple VA examination.Chinese school-aged children in Yangfang school district,Beijing (n=1427,aged 6~12 years old) were randomly grouped for either pure VA examination or for VA plus AL/CR examination.Those suspicious myopic children were informed for further refractive examination.Finally,the cost from screening to definite diagnosis of refractive error was calculated.Generally,compared with VA examination,the total cost was reduced by 15.12% and by 12.34%,respectively,in the elder group using VA plus AL/CR examination.VA plus AL/CR examination is an economical and reasonable method for screening suspicious myopia in Chinese school-aged children compared with pure VA examination.
