Nowosielski Y, Leitner B, Rauchegger T, et al. - Researchers conducted this prospective study to determine brake reaction times before and after bilateral cataract surgery in elderly drivers. Sixty-four participants were assessed on the day of and 4 weeks after bilateral cataract surgery. The control group consisted of 43 healthy people with valid driving licence. Total brake reaction time (BRT), neurologic reaction time (NRT), foot transfer time, and brake pedal travel time were all measured, and the results were compared before and after cataract surgery. Out of the 64 patients with bilateral cataract, 53 were evaluated for postsurgical measurements. A significant negative correlation was found between CS and NRT before surgery. The results show that CS has a significant effect on neurological BRTs and the corresponding stopping distances. This emphasizes the significance of presurgical CS evaluation as a critical factor in cataract surgery decisions in elderly drivers.
