Kısa gözyaşı kırılma zamanı olan hastalarda etafilcon A ve nesofilcon A’nın oküler konfor seviyeleri açısından kıyaslanması: prospektif karşılaştırmalı çalışma

Abstract

Aim: The aim of the study was to compare the two different hydrogel daily disposable contact lenses (HyDDCLs) satisfaction levels in patients with meibomian gland disfunction (MGD) and allergic conjunctivitis accompanied with short noninvasive tear break-up time (NIBUT).
 Material and Methods: Fifty patients who had no history of contact lens and had short NIBUT were included to the study into two groups: allergic conjunctivitis findings (group 1) and MGD findings (group 2). All patients used both etafilcon A and nesofilcon A, respectively. The OSDI (Ocular Surface Disease Index) and CLDEQ-8 (Contact Lens Dry Eye Questionnaire- 8) tests were performed by the patients for each lens and the mean scores were compared. In addition, the decisions of all patients regarding the continued use of each lens were questioned.
 Results: The mean of total scores of OSDI and CLDEQ-8 were statistically lower in nesofilcon A, significantly. The mean scores of the all OSDI subscales and the CLDEQ-8 subscales of dryness, discomfort, blurred vision and closing eyes were lower in nesofilcon A. Four patients (8%) were not satisfied by any of the lenses. 36 (72%) patients preferred nesofilcon A and remaining 10 (20%) patients preferred etafilcon A to continue.
 Conclusion: Due to the hydrophilic structure and low modulus of the HyDDCLs, the satisfaction rate was found to be higher in the study group (92%). HyDDCLs could be a suitable option in cases where ocular surface diseases are accompanied. Hydrogel material with higher water content offers better comfort levels at the end of the day.
