Item 1.                                Security and Issuer
The class of equity securities to which this statement on Schedule 13D relates is the Common Stock of Advanced Medical Optics, Inc. (the “Issuer”), a Delaware corporation with principal offices located at 1700 E. St. Andrew Place, Santa Ana, California 92705.

Item 2.                                Identity and Background
This statement is being filed by Mario J. Gabelli (“Mario Gabelli”) and various entities which he
directly or indirectly controls or for which he acts as chief investment officer.  These entities, except for LICT Corporation (“LICT”), engage in various aspects of the securities business, primarily as investment adviser to various institutional and individual clients, including registered investment companies and pension plans, and as general partner of various private investment partnerships.  Certain of these entities may also make investments for their own accounts.
The foregoing persons in the aggregate often own beneficially more than 5% of a class of a particular issuer.  Although several of the foregoing persons are treated as institutional investors for purposes of reporting their beneficial ownership on the short-form Schedule 13G, the holdings of those who do not qualify as institutional investors may exceed the 1% threshold presented for filing on Schedule 13G or implementation of their investment philosophy may from time to time require action which could be viewed as not completely passive.  In order to avoid any question as to whether their beneficial ownership is being reported on the proper form and in order to provide greater investment flexibility and administrative uniformity, these persons have decided to file their beneficial ownership reports on the more detailed Schedule 13D form rather than on the short-form Schedule 13G and thereby to provide more expansive disclosure than may be necessary.
(a), (b) and (c) - This statement is being filed by one or more of the following persons: GGCP, Inc.  formerly known as Gabelli Group Capital Partners, Inc.

The Reporting Persons used an aggregate of approximately $114,347,142 to purchase the Securities reported as beneficially owned in Item 5.

Item 4.                                Purpose of Transaction
Each of the Reporting Persons has purchased and holds the Securities reported by it for investment for one or more accounts over which it has shared, sole, or both investment and/or voting power, for its own account, or both.
The Reporting Persons, with the exception of  Interactive, are engaged in the business of securities analysis and investment and pursue an investment philosophy of identifying undervalued situations.  In pursuing this investment philosophy, the Reporting Persons analyze the operations, capital structure and markets of companies in which they invest, including the Issuer, on a continuous basis through analysis of documentation and discussions with knowledgeable industry and market observers and with representatives of such companies (often at the invitation of management).  The Reporting Persons do not believe they possess material inside information concerning the Issuer.  As a result of these analytical activities one or more of the Reporting Persons may issue analysts reports, participate in interviews or hold discussions with third parties or with management in which the Reporting Person may suggest or take a position with respect to potential changes in the operations, management or capital structure of such companies as a means of enhancing shareholder values.  Such suggestions or positions may relate to one or more of the transactions specified in clauses (a) through (j) of Item 4 of Schedule 13D including, without limitation, such matters as disposing of one or more businesses, selling the company or acquiring another company or business, changing operating or marketing strategies, adopting or not adopting, certain types of anti-takeover measures and restructuring the company’s capitalization or dividend policy.
Each of the Reporting Persons intends to adhere to the foregoing investment philosophy with respect to the Issuer.  However, none of the Reporting Persons intends to seek control of the Issuer or participate in the management of the Issuer, and any Reporting Person that is registered as an investment company under the 1940 Act will participate in such a transaction only following receipt of an exemption from the SEC under Rule 17d-1 under the 1940 Act, if required, and in accordance with other applicable law.  In pursuing this investment philosophy, each Reporting Person will continuously assess the Issuer’s business, financial condition, results of operations and prospects, general economic conditions, the securities markets in general and those for the Issuer’s securities in particular, other developments and other investment opportunities, as well as the investment objectives and diversification requirements of its shareholders or clients and its fiduciary duties to such shareholders or clients.  Depending on such assessments, one or more of the Reporting Persons may acquire additional Securities or may determine to sell or otherwise dispose of all or some of its holdings of Securities.  Although the Reporting Persons share the same basic investment philosophy and although most portfolio decisions are made by or under the supervision of Mario Gabelli, the investment objectives and diversification requirements of various clients differ from those of other clients so that one or more Reporting Persons may be acquiring Securities while others are disposing of Securities.
With respect to voting of the Securities, the Reporting Persons have adopted general voting policies relating to voting on specified issues affecting corporate governance and shareholder values.  Under these policies, the Reporting Persons generally vote all securities over which they have voting power in favor of cumulative voting, financially reasonable golden parachutes, one share one vote, management cash incentives and pre-emptive rights and against greenmail, poison pills, supermajority voting, blank check preferred stock and super-dilutive stock options.  Exceptions may be made when management otherwise demonstrates superior sensitivity to the needs of shareholders.  In the event that the aggregate voting position of all joint filers shall exceed 25% of the total voting position of the issuer then the proxy voting committees of each of the Funds shall vote their Fund’s shares independently.
Each of the Covered Persons who is not a Reporting Person has purchased the Securities reported herein as beneficially owned by him for investment for his own account or that of one or more members of his immediate family.  Each such person may acquire additional Securities or dispose of some or all of the Securities reported herein with respect to him.
Other than as described above, none of the Reporting Persons and none of the Covered Persons who is not a Reporting Person has any present plans or proposals which relate to or would result in any transaction, change or event specified in clauses (a) through (j) of Item 4 of Schedule 13D.

Item 5.                                Interest In Securities Of The Issuer
(a) The aggregate number of Securities to which this Schedule 13D relates is 3,100,882 shares, representing 5.13% of the 60,458,073 shares outstanding as reported in the Issuer’s most recent Form 10-Q for the quarter ended June 29, 2007. The Reporting Persons beneficially own those Securities as follows:
