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.
