Abstract
Objective To compare the postoperative dry eye status between femtosecond laser assisted phacoemulsification and conventional phacoemulsification. Methods It was a prospective study.A total of 106 eyes of 61 patients were collected and they were divided into 2 groups.Group 1: 52 eyes of 34 patients were performed with femtosecond laser assisted phacoemulsification. And group 2: 54 eyes of 27 patients were performed with conventional phacoemulsification.The tear film break up time(BUT) and inferior tear meniscus height(TMH) were examined with keratograph before , 1 week and 1 month after surgery. The parameters were compared at different time between the two groups. Results The BUT and TMH of two groups at 1 week and 1 month after surgery were lower than those before operation (P 0.05). At 1 month after surgery, the TMH in group 1 was significantly higher than that in group 2, the difference was statistically significant (P=0.015). Conclusion Postoperative dry eye is found after the two surgeries, but dry eye after femtosecond laser assisted phacoemulsification has been restored more rapidly. Key words: Phacoemulsification, famtosecond laser, conventional; Keratograph; Dry eye; Tear film; Tear meniscus
