Corneal sensitivity, ocular surface health and tear film stability after punctal plug therapy of aqueous deficient dry eye

PurposeA new cross-linked hyaluronic acid (xlHA) gel occlusive device was assessed for safety and efficacy in the treatment of dry eyes.MethodsThis was an institutional review board-approved, single-site, open-label, prospective study to assess the efficacy and safety of placing the xlHA gel in the lower canaliculus. Seventy-four participants aged 25–95 years with dry eyes, who failed treatment with artificial tears, were included. Patients were assessed with corneal slit lamp examination with fluorescein staining and with Schirmer’s test, breakup time (TBUT), and tear meniscus height (TMH) at baseline, 1 month, and 3 months. Patients were followed at 6 months with a telephone questionnaire. The procedure entailed inserting ~0.2 mL of xlHA gel into each lower lid canaliculus with a syringe and lacrimal irrigator. Patients were followed for adverse events.ResultsSixty-three patients completed the study (48 females, 15 males), with an average age of 67 years. Slit lamp demonstrated improved corneal fluorescein staining. Schirmer’s tests demonstrated an average increase over baseline of 3.67 mm after 3 months. TBUT improved 87% and TMH increased by 57% at 3 months over baseline. All objective measures were statically significant. There was one case of conjunctivitis that resolved and was felt to be an incidental viral infection.ConclusionThe xlHA Occlusive Device offers a new, safe, and effective method to treat dry eyes. It appears to have efficacy for at least 3 months on clinical examination. The xlHA gel demonstrated a good tolerance and safety profile.

Dry eye disease (DED) is a common multifactorial disease affecting a substantial proportion of the population worldwide. Objective tests and subjective symptoms evaluation are necessary to assess DED. Although various treatments have been introduced, accurately evaluating the efficacy of those treatments is difficult because of the disparity between diagnostic tests and patient-reported symptoms. We reviewed the questionnaires used to evaluate DED and the improvements of quality of life with various treatments. In addition, we highlighted the importance of patient-reported outcomes (PRO) assessments for evaluating the effect of DED treatments. Given that the assessment of DED treatment effectiveness substantially relies on individual ocular experiences, acquiring qualitative PRO data is essential for comprehensive evaluation and optimal treatment management. Clinicians should not only focus on improving objective symptoms but also prioritize the well-being of patients in clinical management.

Corneal sensitivity, ocular surface health and tear film stability after punctal plug therapy of aqueous deficient dry eye

Abstract: Improvement of subjective and objective manifestations of aqueous deficient dry eye occurs following punctal plug occlusion. Thermosensitive plug has good patient's compliance with fewer complications and lower rates of loss compared to the silicone plug.
