Resumen:
Purpose: To assess the effects of cataract surgery on the spontaneous blinking pattern and blinking kinematics.
Setting: FISABIO Oftalmolog ' ia M ' edica Eye Hospital, Valencia, Spain.
Design: Observational descriptive clinical study.
Method: Patients with senile cataract were evaluated before (visit 1) and at 1 month (visit 2) and 3 months (visit 3) after undergoing phacoemulsification cataract surgery. The blinking of patients was recorded for 90 seconds using an eye- tracking device. Blinks were analyzed by means of image analysis to obtain a noninvasive detailed description of blinking including blink rate, number of complete and incomplete blinks, percentage of incomplete blinks, and kinematic parameters, including amplitude, closing, contact, opening, and total durations and closing and opening speeds.
Results: 50 patients were included in this study. The blink rate was significantly smaller at visit 3 comparedwith baseline (P =.03) andvisit 2 (P =.001). Likewise, the number of complete blinks was significantly smaller, and the percentage of incomplete blinks was significantly higher at 3 months postoperatively compared with baseline (P =.02 and P =.01, respectively), although no differences were observed at 1 month postoperatively (P >.05). Conversely, no differences in the number of incomplete blinks or any kinematic parameter were observed between visits (P =.12).
Conclusions: Cataract surgery significantly altered the blinking pattern at 3 months postoperatively, although kinematic parameters remained unvaried. Clinicians should be aware of potential alterations in blinking after phacoemulsification cataract surgery and the implications this may have on the ocular surface of patients.
