WebAn IOL material surface may be hydrophilic or hydrophobic, measured by photographing a water droplet placed onto the material surface. The contact angle measures the degrees between the material’s surface and water droplet’s surface[7]. Large contact angles define hydrophobic materials, whereas smaller angles define hydrophilic materials[7].
