3種消毒方法對眼科檢查用角膜接觸鏡的消毒效果比較
[Abstract]:Objective to observe the disinfection effect of three common disinfection methods on corneal contact lens for ophthalmic examination. Methods Staphylococcus aureus, Staphylococcus epidermidis and Pseudomonas aeruginosa were selected as common ophthalmic bacteria. 0.05% effervescent disinfectant tablets (sodium dichloroisocyanurate) and 75% ethanol were used respectively. Chloramphenicol eye drops were used to disinfect the contact lens surface contaminated by the above bacteria. Immediately after cleaning and disinfecting, 5 min and 10 min after soaking and disinfecting, the lens surface was sampled, and the bacteria were cultured. To compare the disinfection effect of three disinfection methods on common bacteria at different disinfection time. Results all the three disinfection methods were effective in reducing the amount of bacteria on the contact lens, and the disinfection effect was positively correlated with the disinfection time. 0. 05% effervescent disinfectant tablets and 75% alcohol soaking for 10 min could completely kill the bacteria observed. Compared with chloramphenicol eye drops, the disinfection effect was significantly different (P0.01). Chloramphenicol eye drops could not completely kill the bacteria observed after 10 min contact. Conclusion immersion of 0.05% effervescent disinfectant for 10 min is a simple and effective method for corneal contact lens disinfection in ophthalmic examination, but chloramphenicol eye drops cannot be used for contact lens disinfection.
