Abstract
Background Dry eye is a very common eye presentation nowadays due to extensive use of digital devices, so that it was important for us to see the impact of dry eye on corneal topography and wavefront data because it has a strong relation with refractive surgeries. In the past, it was hard to know the effect of dry eye on corneal parameters, but after the new medical technology, it is possible to do that. Aim The aim of the study was to evaluate the effect of dry eye on corneal topography and wavefront data. Patients and methods In total, 40 patients were included in this study with mild and moderate dry eye. Corneal topography and wavefront data were collected before and after treatment with artificial eye drops for 4 weeks. Results Eleven eyes show an increase in peak central corneal thickness after treatment from 1 up to 5 μm. Five eyes show changes in corneal volume after treatment. Eight eyes show a decrease in k1 after treatment. In total, 13 eyes show a decrease in k2 after treatment. Seven eyes show a decrease in root mean square values. Conclusion Dry eye can affect corneal topography increasing the higher order aberrations, so that screening for dry eye is important in the preoperative evaluation of refractive surgery candidates.
