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.
