The THINK Study: Testing Hypoesthesia and the Incidence of Neurotrophic Keratopathy in Cataract Patients with Dry Eye

More than half of patients presenting for cataract evaluation with dry eye had stage 1 neurotrophic keratopathy. These patients had significantly worse higher-order aberrations than patients with normal sensitivity. Among patients with NK, symptoms were milder and age was higher, but neither trend was statistically significant. No trend was observed between corneal sensation and either corneal staining or CDVA.
