Any person desiring to donate and give his eyes for eyesight-restoration purposes may do so by a written instrument declaring such gift or may, by his last will and testament or codicil thereto, bequeath his eyes for such purposes, and any such provision in any last will and testament or codicil shall become effective immediately upon death of the testator.

No particular form or words shall be necessary or required, but any such written statement or last will and testament or codicil shall be liberally construed to effectuate the intent and purpose of the person wishing to donate or bequeath his eyes for eyesight-restoration purposes.
