Item 2. Identity and Background

(a)-(b)

This statement is filed on behalf of BlueLine Capital Partners, LP (“BCP I”), BlueLine Capital Partners II, LP (“BCP II”), BlueLine Catalyst Fund VIII, L.P. (“BlueLine Catalyst VIII”) and BlueLine Partners, L.L.C. (“BlueLine Partners” and, together with BCP I, BCP II and BlueLine Catalyst VIII, “BlueLine” or the “Reporting Entities”). BlueLine Partners is the sole general partner of BCP I, BCP II and BlueLine Catalyst VIII and has an interest in the profits of BCP I, BCP II and BlueLine Catalyst VIII. Timothy Bacci and Scott Shuda are each Managing Directors of BlueLine Partners, L.L.C. Messrs.

The principal business of BlueLine Partners is to serve as investment manager to a variety of private investment funds, including BCP I, BCP II and BlueLine Catalyst VIII, and to control the investing and trading in securities of these private investment funds.

Item 3. Source and Amount of Funds

As of the date hereof, the Reporting Entities may, in the aggregate, be deemed to beneficially own 631,433 shares of the Common Stock (the “Shares”). The Shares were purchased in the open market by BCP I, BCP II and BlueLine Catalyst VIII with their investment capital.

Item 4. Purpose of the Transaction

BlueLine invests in companies it believes are undervalued relative to their potential. In its original September 19, 2005 Schedule 13D filing, BlueLine stated its belief that the Company’s new Chief Executive Officer, Mr. Barry Caldwell, would (i) transition Iridex away from its traditional technology-centric orientation and toward a greater customer and market orientation and (ii) use the Company’s large cash position to expand the Company’s business while better articulating the Company’s potential beyond that as a technology pioneer.

BlueLine believes Mr. Caldwell has proven successful in these areas. Of particular note is (i) the Company’s new emphasis on recurring sales of disposable probes and (ii) the agreement to acquire LaserScope’s aesthetics business for approximately $21 million net of $7 million of accounts receivable to be assumed by Iridex. This transaction will double Iridex’s revenue base and, BlueLine believes, substantially benefit gross margins due to significant operating synergies. BlueLine does not think Iridex’s management will seek to use the Laserscope business as a launching point for a broader expansion into the aesthetics market.

As part of its investment strategy, BlueLine seeks to discuss and work with management on various initiatives designed to improve the Company’s prospects and performance. Areas of focus will include investor relations, strategic transactions and integration issues.

Depending on market conditions, general economic conditions and other factors, the Reporting Entities may purchase additional shares of Common Stock in the open market or in private transactions, or may dispose of all or a portion of the shares of Common Stock that they or any of them presently own or may hereafter acquire.

Item 5. Interest in Securities of the Issuer

(a)

As of the date of this Schedule 13D, each of the Reporting Entities may be deemed to own 631,433 shares of Common Stock. These shares represent approximately 8.1% of the shares of Common Stock outstanding based on 7,829,948 shares of the Company’s Common Stock outstanding as reported in the Company’s Form 10-Q for the Company’s fiscal quarter ended September 30, 2006 as filed with the Securities and Exchange Commission on December 22, 2006.


  The Reporting Entities are making this single, joint filing because they may be deemed to constitute a “group” within the meaning of Section 13(d)(3) of the Act. Each Reporting Entity expressly disclaims beneficial ownership of any of the shares of Common Stock other than those reported herein as being owned by it.
