ABSTRACT
PURPOSE:
In this study we compared the surface wettability of ocular prosthesis and depositions depending on different types of artificial tear eye drops.METHODS:
The artificial tear eye drops contain sodium hyaluronate (HA) 0.1%, 0.18%, 0.3%, carboxylmethylcellulose sodium (CMC), hydroxymethylcelluose + dextran (HMC), propylene glycol + polyethylene glycol (PG), polysorbate 80 (PS) povidone (Pov) were evaluated. Flat rectangular parallelepiped blocks consisting of polymethylmethacrylate (PMMA) or silicone materials were made. One artificial tear eye drop was applied on the surface of two different blocks of artificial eyes using a 23-gauge needle. Then, the static method contact angle was measured by using a contact angle goniometer. To measure the deposits, a petri dish was covered with 3 mL of artificial tear eye drops and dried for 48 hours at room temperature. Then, the light transmittance at the center of the petri dish was measured to investigate the amount of the residue.RESULTS:
The contact angles of HA 0.1%, 0.18%, 0.3%, CMC, HMC, PG, PS and Pov on PMMA were 78.69degrees, 84.29degrees, 75.46degrees, 80.93degrees, 66.29degrees, 71.26degrees, 58.40degrees and 70.24degrees, respectively. The contact angles on silicone were 53.68degrees, 60.87degrees, 64.46degrees, 62.78degrees, 38.89degrees, 63.58degrees, 30.68degrees and 51.41degrees, respectively. The largest decrease in transparency was observed in the artificial tear eye drops containing HMC.CONCLUSIONS:
The wettability and deposits on the surface of ocular prosthesis can vary based on the components and concentration of artificial tear eye drops. The results from this study should be considered when choosing the right artificial tear eye drops for improving dry eye symptoms in patients wearing ocular prostheses.
