Knowledge, attitude and practice of medical students using contact lenses

Introduction: Contact lens usage is associated with various complications, many of which are preventable if the user is aware of them and strictly follows their ophthalmologists instructions with regard to hygiene and regular replacement of the lenses. The purpose of this cross sectional study was to assess the knowledge, attitude and practice of medical students using contact lens. As the participants were medical students, we expected a high level of knowledge regarding contact lens usage. Materials and Methods: A cross sectional study was conducted among the medical students using contact lens. A sample size of 50 was chosen. This was a questionnaire based study and a pre tested questionnaire was given to the participants to assess their knowledge, attitude and practice of contact lens use. Questions about the use of contact lenses, how to maintain them and awareness of the complications they may encounter due to improper use of contact lenses were asked in the questionnaire. Data was collected and tabulated in MS Excel, and further analyzed using SPSS software version 22.00. Results: Consultation of ophthalmologist on finding deposits on the lens was significant (P<0.05), 33.33%(1st year), 70.58%(2nd year), 58.82%(3rd year), 16.66%(4th year), 25%(CRRI) continued to use the contact lens. Use of contact lens following conjunctivitis was significant (P<0.05), 83.33%(1st year), 82.35%(2nd year), 100%(3rd year), 33.33%(4th year), 100%(CRRI) continued to use their contact lens. Knowledge of over-wear syndrome was significant (P<0.05), 50%(1st year), 29.41%(2nd year), 17.64%(3rd year), 66.66%(4th year), 75%(CRRI) had knowledge of over-wear syndrome. Conclusion: The main aim of the study was to assess awareness among the users about the lens care practices, regular cleaning and replacement of lens cases. Many students were found to be unaware of these complications. In conclusion, though health care professionals have knowledge about contact lens, they did not show correct practice of using contact lens with compliance being the major factor. Education, improving communication, behavioral modifications are important to improve the compliance.
