     I hereby constitute and appoint Lori Freedman, signing singly, my true and
lawful attorney-in-fact to:

     (1)  execute for and on my behalf, in my capacity as a director of
          pSivida Corp. (the "Company"), Forms 3, 4 and 5 in accordance with
          Section 16(a) of the Securities Exchange Act of 1934 and the rules
          thereunder; and

     (2)  do and perform any and all acts for and on my behalf that may be
          necessary or desirable to complete and execute any such Form 3, 4 or 5
          and timely file such form with the United States Securities and
          Exchange Commission and any stock exchange or similar authority.

     I hereby grant to such attorney-in-fact full power and authority to do and
perform any and every act and thing whatsoever requisite, necessary, or proper
to be done in the exercise of any of the rights and powers herein granted, as
fully to all intents and purposes as I might or could do if personally present,
with full power of substitution or revocation, hereby ratifying and confirming
all that such attorney-in-fact, or such attorney-in-fact's substitute or
substitutes, shall lawfully do or cause to be done by virtue of this power of
attorney and the rights and powers herein granted.  I acknowledge that the
attorney-in-fact, in serving in such capacity at my request, is not assuming,
nor is the Company assuming, any of my responsibilities to comply with Section
16 of the Securities Exchange Act of 1934.

     This Power of Attorney shall remain in full force and effect until I am no
longer required to file Forms 3, 4 and 5 with respect to my holdings of and
transactions in Company securities, unless I  earlier revoke it in a signed
writing delivered to the attorneys-in-fact.

     IN WITNESS WHEREOF, I have caused this Power of Attorney to be executed as
of this 11th day of September, 2014.
