Major Scientific Interests of the GroupTo investigate quality of vision (QOV) and quality of life (QOL) in patients with ocular diseases. To
improve outcomes of ocular therapies especially surgical treatments.
Projects for Regular Students in Doctoral or Master’s Programs
1) Application of artificial intelligence in ophthalmic practices2) Development and clinical application of artificial vitreous3) Comprehensive assessment and improvement of visual function in patients after cataract andvitreoretinal surgery
4) Development of next-generation of optical coherence tomography5) Assessment of surgical outcomes of new intraocular lenses
6) Suppression of myopia progression in children
7) Establishment of infrastructure for artificial intelligence and big data study in ophthalmology
Study Programs for Short Stay Students (one week – one trimester)1) To learn the methods to comprehensively assess visual function of patients rather than visualacuity2) To understand how to improve outcomes of cataract surgery using premium intraocular lenses
