Evaluation of Ocular Surface after Cataract Surgery-A Prospective Study.

UNLABELLED: This study evaluated tear film and ocular surface parameters in patients after cataract surgery.

METHODS

a prospective clinical study included 48 eyes of 48 patients who underwent uncomplicated phacoemulsification performed by one surgeon. Tear break-up time (TBUT), Schirmer's I test, Cochet-Bonnet esthesiometry and in vivo laser scanning confocal microscopy was carried out and the OSDI questionnaire was filled out. All tests were assessed before and 1 month after the surgery.

RESULTS

there were 32 (66.7%) women; 16 (33.3%) men, mean age was 74.08 ± 5.37. Mean TBUT at baseline was 8.6 ± 1.9 s, after the surgery, it was 7.7 ± 2.7 s, p = 0.004. Schirmer's I test was 8.7 ± 3.9 mm versus 8.1 ± 3.7 mm, p = 0.002. Mean corneal nerve density at baseline was 15.70 ± 2.34 and at the first postoperative month 14.94 ± 1.48 mm/mm2, p = 0.02. The OSDI questionnaire score increased from 12.15 ± 10.34 before the surgery to 13.79 ± 10.88 in the first postoperative month, p = 0.001.

CONCLUSIONS

the ocular surface was affected 1 month after the cataract surgery: TBUT was shorter, Schirmer's I test and corneal nerve density were decreased while the OSDI score increased.
