| 内容記述 | PURPOSE: To evaluate the characteristics and formation mechanism of condensation on the posterior surface of various types of intraocular lenses (IOLs) during vitreous surgery. METHODS: A model eye was immersed in a constant-temperature bath, and the temperature and humidity inside the vitreous cavity were maintained at 35˚C and 97%, respectively, to cause condensation (moisture formation) on the IOL. The condensation was video recorded under a microscope, and the size of the condensation droplets and the number per unit area (500 μm2) were determined. The contact angle of the water droplets on each IOL was evaluated by using the sessile-drop method. RESULTS: The condensation droplet diameter for the polymethyl methacrylate (PMMA), acrylic, and silicone IOLs was 115 ± 32 μm, 74 ± 23 μm, and 50 ± 13 μm, respectively. The number of droplets per unit area was 18.4 ± 1.8, 48.2 ± 16.8, and 86.8 ± 6.7, respectively. Statistical analysis showed significantly smaller sizes but a greater number of droplets per unit area for the silicone IOL. The contact angle for the PMMA, acrylic, and silicone IOLs was 76.4˚, 85.7˚, and 112.8˚, respectively. Thus, for silicone, the contact angle was lowest and the water droplets were spherical. CONCLUSIONS: Condensation occurs regardless of the IOL material. Compared to other IOLs, the silicone IOL had smaller-sized but a larger number of spherical condensation droplets. This can cause a large amount of refraction of intraocular light, thus leading to decreased visibility. |
