Technical Evaluation of Eye Drops Instillation: A Systematic Review

Abstract

Abstract:Objective: Assess the profile of eye drops in patients with eye diseases. Methods: Studies available in the scientific literature were identified without any time limits using the databases Embase-Medline, Scielo, Scopus and Web of Knowledge. The selected studies were compared with the following inclusion criteria: (i) if the study evaluated the eye drop instillation, (ii) if the study involved participation of patients with eye diseases. Results: Twelve studies met the inclusion criteria. Of them, 83.33% evaluated the technique of eye drop instillation in patients with glaucoma, 8.33% in patients with eye diseases and 8.33% in patients with cataract after undergoing surgery to correct. 41.66% of studies have chosen to record a video of patients to analyze the technique of instilling eye drops and 41.66% did not describe the/esearch location. Regarding the type of study, 75% had the design as prospective cross-sectional, 8.33% prospective open label study, 8.33% intervention study and 8.33% study called masked trial. Although studies evaluate the technique of eye drop instillation, only 8.33% describe in the article the reference in the literature used to evaluate patients. 50% of articles acknowledged some sort of bias or limitation. Conclusion: The limitations inherent in these types of studies should guide future research.
