Abstract Details

Purpose:

To compare the changes in tear film and corneal sensitivity after femtosecond laser-assisted cataract surgery and microincisional phacoemulsification.

Setting:

This is prospective, clinical case-control study.

Methods:

Fifty-three eyes of fifty-three patients with age-related cataract were divided into two groups according to the surgical approach. Schirmer test without anesthesia, non-invasive tear break time(NIBUT),corneal sensitivity and subjective score for dryness were compared among two groups.

Results:

1 daYy7 days and 1 month postoperatively, both the mean NIBUT and Schirmer test of the microincisional group reduced greatly than the femtosecond laser group. The values recovered to preoperative levels at 3 months postoperatively． At 1 day 、7 days、1 month and 3 months post-operatively, the mean subjective scores for dryness of the microincisional group were higher than the femtosecond laser group； At 1 day、7 days、1 month postoperatively, the upper corneal sensitivity of the microincisional group was shorter than the femtosecond laser group，and all recovered to the preoperative levels at 3 months postoperatively．There was no statistically significant difference among the two groups at any time point for central corneal sensitivity.

Conclusions:

Femtosecond laser-assisted cataract surgery bring less disturbance to ocular surface，brighter symptoms of dry eye，faster recovery of corneal sensitivity and the patients feel more comfortable．
