Research projects in the Customized Correction Laboratory have been focusing on optics of the eye. The goals of
the projects are to objectively understand optical quality of the eye and to improve visual performance by correcting
the optical defects in the eye with various correction methods. We have successfully developed the large dynamic range
wavefront sensor with high measurement sensitivity that allows us to measure highly aberrated eyes such as advanced
keratoconus. We have also developed the customized correction methods. These include customized optical components such
as phase plate and soft contact lenses, and laser refractive surgery. We recently implemented the large stroke adaptive
optics system for vision testing that has sufficient deformable mirror stroke to correct the highly aberrated eyes such
as advanced keratoconus. This powerful tool is being used to understand interaction between optics of the eye and
adaptation effects of the human visual system. We are currently expanding our research scope to presbyopia, accommodation
and dry eye with advanced intraocular imaging system such as Sheimpflug and Fourier domain optical coherence tomography.
We have also been very active in collaborating with PIs in intramural and extramural research
laboratories and industry.
