Corneal topography and tomography
Journal of Clinical Ophthalmology and Research, 2015 Devices that evaluate corneal properties are an indispensible tool in a eye clinic nowadays. With the arrival of new technology in addition to placido based devices, the options available now are many. Cornea based refractive surgery in Indian eyes poses

Placido-based indices of corneal irregularity [PDF]
, 2011 Purpose: To construct a set of metrics computed from the raw keratoscopic data collected by any Placido corneal topographer. These indices that measure the irregularity of the anterior corneal surface are computed directly from the image of the mires ...

Advanced Functional Materials, EarlyView.We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,
