[Application of Smart Plug lacrimal plug in the treatment of dry eye].

OBJECTIVE

To evaluate the clinical efficacy of Smart Plug lacrimal plug in the treatment of dry eye.

METHODS

Twenty-nine patients with dry eyes (58 eyes) were treated with Smart Plug lacrimal plug. All the patients were follow up for 6-10 months (average 7.8 months). Schirmer I test (SIT), tear break-up time (TBUT) and corneal fluorescein staining were used for evaluation of the clinical efficacy.

RESULTS

The SIT was 3.35∓2.60 mm and 6.35∓4.15 mm, TBUT was 3.14∓1.22 s and 5.46∓1.26 s, and corneal fluorescein staining was 2.15∓0.09 and 0.05∓0.01 before and after the treatment, respectively (P<0.05). The subjective symptoms were improved in most of the patients.

CONCLUSION

Smart Plug lacrimal plug is effective in the treatment of dry eye due to aqueous tear deficiency, and can be one of the choice of dry eye treatment.
