Optical Correction of Keratoconus with a Scleral Gas-Permeable Lenses
Oftalʹmologiâ, 2019 The optical properties of the cornea are determined by its ability to refract and transmit light. Keratoconus changes cornea’s shape, the surface of the cornea becomes irregular, which leads to a violation of light refraction and the occurrence of ...

Punctuated evolution of canonical genomic aberrations in uveal melanoma
Nature Communications, 2018 Cancer is thought to arise through the accumulation of genomic aberrations evolving under Darwinian selection. However, it remains unclear when the aberrations associated with metastasis emerge during tumor evolution.
