Central islands after LASIK detected by corneal topography
Korean Journal of Ophthalmology, 2001 A central island is defined as a localized elevated area in corneal topography after excimer laser application for myopic correction. We experienced 15 cases of central islands developed 1 week after LASIK using VISX STAR on corneal topography. The uncorrected visual acuity and best corrected visual acuity were 0.52 +/- 0.22, 0.66 +/- 0.25 in central ...

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,
