According to research by scientists at the Schepens Eye Research Institute, people with a certain low level of tear production have a higher probability of developing chronic dry eye syndrome after having undergone LASIK surgery. The laser refractive surgery is done to correct near- and far-sightedness. The study, published in Investigative Ophthalmology and Vision Science, may help ophthalmologists find out if these patients require pretreatment and whether or not surgery is appropriate for such persons.

The Schepens Eye Research Institute have discovered a chemical in the eye that triggers non-neuronal cells to turn into progenitor cells, a stem-like cell that can generate new retinal cells. The research is published in the Investigative Ophthalmology and Visual Science journal, and offers hope for patients with damaged retinas due to diseases such as macular degeneration and retinitis pigmentosa.
