Comparison Of Lasik Preoperative And Postoperative Blink Rate.

This is an observational study comparing the blink rate before LASIK and after LASIK. Observations took place during the preoperative and one day postoperative LASIK visits at two primary eye care clinics. The LASIK patients were observed while doing an oral survey titled LASIK Preoperative and Postoperative Patient Expectations, masking the studies true title, LASIK Preoperative and Postoperative Blink Rate. The preoperative blink rate was counted for 15 seconds and compared to the postoperative blink rate. In seven out of ten patients there was a decrease in blink rate postoperatively. This study was done to increase the awareness of dry eye symptoms for both doctors and future LASIK patients.
