Purpose: The aim of the present study was to investigate changes in research trends in the Journal of Korean Ophthalmic Optics Society using a key word analysis.
Methods: Filtering work carried out targeting author key words indicated in the Korean abstract of the papers published in Journal of Korean Ophthalmic Optics Society, and the study period (4 period, period 1: 2004~2006, period 2: 2007~2011, period 3: 2012~2016, and period 4: 2017~2022) was set. By analyzing the appearance frequency of key words in each study period, the top five key words were identified. In addition, the co-occurrence frequency and centrality network analyses were conducted for key words that appeared together in papers, with the top five key words by appearance frequency.
Results: Key words with the top five appearance frequency were ‘phoria, soft contact lens, myopia, binocular vision, contact lens, refractive error, astigmatism, and ophthalmic lens’ in period 1, ‘soft contact lens, binocular vision, RGP, phoria, blink, ophthalmic lens, refractive error, myopia, astigmatism, vision training, and optician’ in period 2, ‘refractive error, myopia, contrast sensitivity, phoria, visual acuity, contact lens, NIBUT, and optical shop’ in period 3, and ‘optician, soft contact lens, refractive error, subjective symptoms, and contrast sensitivity’ in period 4. Key words with the highest co-occurrence frequency in each study period were ‘phoria-binocular vision’ 5 times in period 1, ‘myopia-astigmatism’ 4 times in period 2, ‘refractive error-myopia’ 7 times in period 3, and ‘optician-refractive error’ and ‘soft contact lens-subjective symptoms’ 1 time each in period 4.
Conclusions: This study on research trends in the Journal of Korean Ophthalmic Optics Society revealed the topics most commonly studied in four study periods. Further, even among articles containing the same key words, contents of the study may be different, and the scope of the study may differ among study periods.
