Abstract

The visual loss caused by corneal injury or cataract would affect patients’ daily life. For recovering the vision loss caused by those situations, artificial cornea and intraocular lens are invented [1] [2]. Artificial corneas and intraocular lens are usually made by hydrogel biomaterials. The hydrogel biomaterial is a type of soft hydrogel material with biocompatibility. However, the optical properties may be different after the hydrogel biomaterial shape change during fabrications. To measure the optical properties of hydrogel biomaterial with designed shape, the wavefront aberrations are measured to evaluate the optical performance of the samples and the refractive index of hydrogel biomaterial with specific shape can be analyzed.
