EXHIBIT 10.8

INTRALASE CORP.

STOCK OPTION AGREEMENT

This Stock Option Agreement (the “Agreement”) is entered into as of             , 200  , by and between IntraLase Corp., a Delaware corporation (the “Company”), and                                                           (the “Optionee”) pursuant to the Company’s 2004 Stock Incentive Plan (the “Plan”). Any capitalized term not defined herein shall have the same meaning ascribed to it in the Plan.

1. Grant of Option. The Company hereby grants to Optionee an option (the “Option”) to purchase all or any portion of a total of _____________________________ (__________) shares (the “Shares”) of the Common Stock of the Company at a purchase price of _________________________ ($__________) per share (the “Exercise Price”), subject to the terms and conditions set forth herein and the provisions of the Plan. If the box marked “Incentive” above is checked, then this Option is intended to qualify as an “incentive stock option” as defined in Section 422 of the Internal Revenue Code of l986, as amended (the “Code”). If this Option fails in whole or in part to qualify as an incentive stock option, or if the box marked “Nonqualified” is checked, then this Option shall to that extent constitute a nonqualified stock option.

2. Vesting of Option. The right to exercise this Option shall vest in installments, and this Option shall be exercisable from time to time in whole or in part as to any vested installment, as follows:

This Option shall:

No additional Shares shall vest after the date of termination of Optionee’s “Continuous Service” (as defined in Section 3 below), but this Option shall continue to be exercisable in accordance with Section 3 hereof with respect to that number of shares that have vested as of the date of termination of Optionee’s Continuous Service (as defined in Section 3 below).

3. Term of Option. Optionee’s right to exercise this Option shall terminate upon the first to occur of the following:

(a) the expiration of ten (10) years from the date of this Agreement;

(b) the expiration of three (3) months from the date of termination of Optionee’s Continuous Service if such termination occurs for any reason other than permanent

disability or death; provided, however, that if Optionee dies during such three-month period the provisions of Section 3(d) below shall apply;

(c) the expiration of one (1) year from the date of termination of Optionee’s Continuous Service if such termination is due to permanent disability of the Optionee (as defined in Section 22(e)(3) of the Code);

(d) the expiration of one (1) year from the date of termination of Optionee’s Continuous Service if such termination is due to Optionee’s death or if death occurs during the three-month period following termination of Optionee’s Continuous Service pursuant to Section 3(b) above; or

(e) upon the consummation of a “Change in Control” (as defined in Section 2.6 of the Plan), unless otherwise provided pursuant to Section 8 below.

As used herein, the term “Continuous Service” means (i) employment by either the Company or any parent or subsidiary corporation of the Company, or by a corporation or a parent or subsidiary of a corporation issuing or assuming a stock option in a transaction to which Section 424(a) of the Code applies, which is uninterrupted except for vacations, illness (except for permanent disability, as defined in Section 22(e)(3) of the Code), or leaves of absence which are approved in writing by the Company or any of such other employer corporations, if applicable, (ii) service as a member of the Board of Directors of the Company until Optionee resigns, is removed from office, or Optionee’s term of office expires and he or she is not reelected, or (iii) so long as Optionee is engaged as a consultant or service provider to the Company or other corporation referred to in clause (i) above.

4. Exercise of Option. On or after the vesting of any portion of this Option in accordance with Sections 2 or 8 hereof, and until termination of the right to exercise this Option in accordance with Section 3 above, the portion of this Option which has vested may be exercised in whole or in part by the Optionee (or, after his or her death, by the person designated in Section 5 below) upon delivery of the following to the Company at its principal executive offices:

(a) a written notice of exercise which identifies this Agreement and states the number of Shares then being purchased (but no fractional Shares may be purchased);

(b) a check or cash in the amount of the Exercise Price (or payment of the Exercise Price in such other form of lawful consideration as the Administrator may approve from time to time under the provisions of Section 5.3 of the Plan);

(c) a check or cash in the amount reasonably requested by the Company to satisfy the Company’s withholding obligations under federal, state or other applicable tax laws with respect to the taxable income, if any, recognized by the Optionee in connection with the exercise of this Option (unless the Company and Optionee shall have made other arrangements for deductions or withholding from Optionee’s wages, bonus or other compensation payable to Optionee, or by the withholding of Shares issuable upon exercise of this Option or the delivery of Shares owned by the Optionee in accordance with Section 12.1 of the Plan, provided such arrangements satisfy the requirements of applicable tax laws); and

2

(d) a letter, if requested by the Company, in such form and substance as the Company may require, setting forth the investment intent of the Optionee, or person designated in Section 5 below, as the case may be.

5. Death of Optionee; No Assignment. The rights of the Optionee under this Agreement may not be assigned or transferred except by will or by the laws of descent and distribution, and may be exercised during the lifetime of the Optionee only by such Optionee. Any attempt to sell, pledge, assign, hypothecate, transfer or dispose of this Option in contravention of this Agreement or the Plan shall be void and shall have no effect. If the Optionee’s Continuous Service terminates as a result of his or her death, and provided Optionee’s rights hereunder shall have vested pursuant to Section 2 hereof, Optionee’s legal representative, his or her legatee, or the person who acquired the right to exercise this Option by reason of the death of the Optionee (individually, a “Successor”) shall succeed to the Optionee’s rights and obligations under this Agreement. After the death of the Optionee, only a Successor may exercise this Option.

6. Representation of Optionee. Optionee acknowledges receipt of a copy of the Plan and understands that all rights and obligations connected with this Option are set forth in this Agreement and the Plan.

7. “Market Stand-Off” Agreement. Optionee hereby agrees that during the period of duration specified by the Company and an underwriter of Common Stock or other securities of the Company, following the effective date of a registration statement of the Company filed under the Securities Act, it shall not, to the extent requested by the Company and such underwriter, directly or indirectly sell, offer to sell, contract to sell (including, without limitation, any short sale), grant any option to purchase or otherwise transfer or dispose of (other than to donees who agree to be similarly bound) any securities of the Company held by it at any time during such period except Common Stock included in such registration; provided, however, that:

(a) such agreement shall be applicable only to the registration statement of the Company which covers Common Stock to be sold on its behalf to the public in (i) the Company’s initial firm commitment underwritten public offering of equity securities, and (ii) any firm commitment underwritten public offering of equity securities subject to a registration statement the effective date of which is within 12 months of the effective date of the first registration statement for a public offering of the securities of the Company;

(b) such market stand-off time period shall not exceed 180 days; and

(c) such agreement shall not apply to the sale of any shares to such underwriter pursuant to an underwriting agreement.

In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to the Shares of Optionee (and the shares or securities of every other person subject to the foregoing restriction) under the end of such period.

8. Adjustments Upon Changes in Capital Structure. In the event that the outstanding shares of Common Stock of the Company are hereafter increased or decreased or changed into or exchanged for a different number or kind of shares or other securities of the Company by reason of a recapitalization, stock split, combination of shares, reclassification, stock dividend or other change in the capital structure of the Company, then appropriate adjustment shall be made by the Administrator

3

to the number of Shares subject to the unexercised portion of this Option and to the Exercise Price per share, in order to preserve, as nearly as practical, but not to increase, the benefits of the Optionee under this Option, in accordance with the provisions of Section 4.3 of the Plan.

9. Change in Control. In the event of a Change in Control (as defined in Section 2.6 of the Plan):

(a) The right to exercise this Option shall accelerate automatically and vest in full (notwithstanding the provisions of Section 2 above) effective as of immediately prior to the consummation of the Change in Control unless this Option is to be assumed by the acquiring or successor entity (or parent thereof) or a new option or New Incentives are to be issued in exchange therefor, as provided in subsection (b) below. If vesting of this Option will accelerate pursuant to the preceding sentence, the Administrator in its discretion may provide, in connection with the Change in Control transaction, for the purchase or exchange of this Option for an amount of cash or other property having a value equal to the difference (or “spread”) between: (x) the value of the cash or other property that the Optionee would have received pursuant to the Change in Control transaction in exchange for the Shares issuable upon exercise of this Option had this Option been exercised immediately prior to the Change in Control minus (y) the aggregate Exercise Price for such Shares. If the vesting of this Option will accelerate pursuant to this subsection (a), then the Administrator shall cause written notice of the Change in Control transaction to be given to the Optionee not less than fifteen (15) days prior to the anticipated effective date of the proposed transaction.

(b) The time period relating to the exercise or realization of [twenty-five percent (25%) / fifty percent (50%)] of the outstanding unvested Options hereunder at the time of a Change of Control of the Company shall accelerate if and to the extent that: (i) this Option (including the unvested portion thereof) is to be assumed by the acquiring or successor entity (or parent thereof) or a new option of comparable value is to be issued in exchange therefor pursuant to the terms of the Change in Control transaction, or (ii) this Option (including the unvested portion thereof) is to be replaced by the acquiring or successor entity (or parent thereof) with other incentives of comparable value under a new incentive program (“New Incentives”) containing such terms and provisions as the Administrator in its discretion may consider equitable. If this Option is assumed, or if a new option of comparable value is issued in exchange therefor, then this Option or the new option shall be appropriately adjusted, concurrently with the Change in Control, to apply to the number and class of securities or other property that the Optionee would have received pursuant to the Change in Control transaction in exchange for the Shares issuable upon exercise of this Option had this Option been exercised immediately prior to the Change in Control, and appropriate adjustment also shall be made to the Exercise Price such that the aggregate Exercise Price of this Option or the new option shall remain the same as nearly as practicable.

(c) If the provisions of subsection (b) above apply, then this Option, the new option or the New Incentives shall with respect to the remaining unvested Options continue to vest and become exercisable thereafter in installments on each vesting date in accordance with the provisions of Section 2 hereof, each such installment to be reduced by a pro-rata portion of the Options which have become exercisable as set forth in Section 8(b), and shall continue in effect for the remainder of the term of this Option in accordance with the provisions of Section 3 hereof. However, in the event of an Involuntary Termination (as defined in the Plan) of Optionee’s Continuous Service within twelve (12) months following such Change in Control, then vesting of this Option, the new option or the New Incentives shall accelerate [OPTION ONE – OFFICERS AND

4

DIRECTORS: in full automatically effective upon such Involuntary Termination. OPTION TWO – ALL OTHERS: by             % automatically effective upon such Involuntary Termination.]

10. No Employment Contract Created. Neither the granting of this Option nor the exercise hereof shall be construed as granting to the Optionee any right with respect to continuance of employment by the Company or any of its subsidiaries. The right of the Company or any of its subsidiaries to terminate at will the Optionee’s employment at any time (whether by dismissal, discharge or otherwise), with or without cause, is specifically reserved.

11. Rights as Stockholder. The Optionee (or transferee of this option by will or by the laws of descent and distribution) shall have no rights as a stockholder with respect to any Shares covered by this Option until the date of the issuance of a stock certificate or certificates to him or her for such Shares, notwithstanding the exercise of this Option.

12. Notice of Disqualifying Disposition. To obtain certain tax benefits afforded to Incentive Options, an Optionee must hold the shares issued upon the exercise of an Incentive Option for two years after the date of grant of the Option and one year from the date of exercise. By executing this Agreement, Optionee hereby agrees to promptly notify the Company’s Chief Financial Officer of any disposition of Shares within one year from the date this Option is exercised or within two years of the date of grant of this Option.

13. Interpretation. This Option is granted pursuant to the terms of the Plan, and shall in all respects be interpreted in accordance therewith. The Administrator shall interpret and construe this Option and the Plan, and any action, decision, interpretation or determination made in good faith by the Administrator shall be final and binding on the Company and the Optionee. As used in this Agreement, the term “Administrator” shall refer to the committee of the Board of Directors of the Company appointed to administer the Plan, and if no such committee has been appointed, the term Administrator shall mean the Board of Directors.

14. Notices. Any notice, demand or request required or permitted to be given under this Agreement shall be in writing and shall be deemed given when delivered personally or three (3) days after being deposited in the United States mail, as certified or registered mail, with postage prepaid, (or by such other method as the Administrator may from time to time deem appropriate), and addressed, if to the Company, at its principal place of business, Attention: the Chief Financial Officer, and if to the Optionee, at his or her most recent address as shown in the employment or stock records of the Company.

15. Governing Law. This Agreement shall be construed in accordance with the laws of the State of Delaware without reference to choice of law principles, as to all matters, including, but not limited to, matters of validity, construction, effect or performance.

16. Severability. Should any provision or portion of this Agreement be held to be unenforceable or invalid for any reason, the remaining provisions and portions of this Agreement shall be unaffected by such holding.

17. Attorneys’ Fees. If any party shall bring an action in law or equity against another to enforce or interpret any of the terms, covenants and provisions of this Agreement, the prevailing party in such action shall be entitled to recover from the other party reasonable attorneys’ fees and costs.

5

18. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall be deemed one instrument.
