How to publish in this journal


The primary mission of JKOS is to provide essential knowledge for ophthalmology residents, general ophthalmologists, and ophthalmology subspecialists to further elevate the level of ophthalmology by publishing creative, original, and clinically significant research under rigorous peer review. The ultimate goal of JKOS is to contribute to human’s health and well-being by improving and educating the science and technologies of ophthalmology. JKOS has kept its reputation in continuing to be the main medium facilitating communication between ophthalmology specialists and readers. Korean board-certified ophthalmologists, ophthalmology residents, and physicians practicing ophthalmology-related medical care have been the general readers of JKOS and this tradition will certainly continue. The JKOS has a larger reader population than the Korean Journal of Ophthalmology (KJO), an English-only journal published by KJO. Being the major ophthalmology journal in Korea, the JKOS has promoted lifelong learning for ophthalmologists and encouraged ophthalmology residents by allowing them more publishing opportunities. The JKOS is distributed to members of the KOS, medical schools, libraries, and many other institutions in Korea and abroad to promote the expansion of Korean ophthalmology and academic exchanges among KOS members and the international ophthalmology society.
