Abstract:
AIM: To compare the adherent ability of Acanthamoeba to three kinds of contact lens (CL) and survey the effect to remove the Acanthamoeba from the surface of contact lens after blowing with stroke-physiological saline solution (SPSS) repeatedly.METHODS: Three kinds of contact lens were chosen in this experiment, including: rigid gas permeable (RGP) contact lens, soft contact lens (SCL) and colored contact lens. They were co-cultivated with Acanthamoeba suspension for 16 hours. Then the number of Acanthamoeba adhered on CL was compared. Comparison was also made between different zones of colored CL. We also compared the number of Acanthamoeba adhered on CL in three groups after blowing with SPSS.RESULTS: The number of Acanthamoeba adhered to colored CL was more than RGP group and SCL group (P<0.05). The differences between RGP group and SCL group had no statistical significance (P>0.05). In colored CL group, the number of Acanthamoeba adhered to the colored zone was more than the Uncolored zone (P<0.01). In all the three groups, after blowing with SPSS, there was statistically significant decrease of the number of Acanthamoeba adhered to CL (P<0.01).CONCLUSION: Compared with RGP group and SCL group, the colored contact lens was more vulnerable to be adhered by Acanthamoeba. After being blown by SPSS repeatedly, the effect to eliminate Acanthamoeba has been improved greatly.
