Eye drop aims to clear the blur for night driving after laser surgery
NCT ID NCT06349759
Summary
This study tested whether a prescription eye drop called phentolamine can improve night vision in people who had laser eye surgery (like LASIK) and now experience problems like glare and halos, especially in low light. About 200 participants were randomly assigned to receive either the active eye drop or a placebo (inactive) drop to compare safety and effectiveness. The main goal was to see if the drops could help people read more letters on a special low-contrast eye chart under dim lighting conditions.
