Trehalose efficacy in dry eye syndrome treatment after phacoemulsification

Cover Page


Purpose to estimate the efficacy of “artificial tear” preparation on the trehalose base in dry eye syndrome treatment in cataract patients after phacoemulsification.

Materials and methods: in 40 patients with incipient cataract phacoemulsification with IOL implantation was performed. During 1 week, all patients received eye gel with dexpanthenol in addition to postoperative therapy. Then, all patients were divided into two groups (randomization using envelopes): in the main group, the gel was replaced by Thealoz®, in the control group, the gel was discontinued. Special investigation tests (OSDI score, TBUT test, conjunctival hyperemia, corneal confocal tomography) were performed before surgery, in one week and one month after it. Statistical analysis was performed using SAS 9.4 program.

Results: all investigated parameters had significant differences with time and between groups (р < 0.001). TBUT test result decreased in one week after surgery from 7.4 ± 2.1 to 4.6 ± 1.9 sec in the main group and from 7.5 ± 2.3 to 4.4 ± 2 sec in the control group. Return to baseline results in the control group was slowed down and made 6.4 ± 2.8 sec (compared with 7.9 ± 2.4 sec in the main one). In the trehalose group, OSDI score ameliorated from 35.1 ± 8.7 (in one week) to 14.2 ± 5.3 (in one month), in the control group, from 40.1 ± 11.5 to 24.8 ± 9. Conjunctival hyperemia was also less pronounced in the main group in one month after surgery: 0.45 ± 0.6 (1.6 ± 0.7 in one week), in the control group, these indices were equal to 1.7 ± 0.5 (in one week) and 1.3 ± 0.7 (in one month).

Conclusions: Thealoz® use as a part of combined postoperative therapy helps to effectively fight against dry eye syndrome main signs and enhances treatment tolerance.
