        and permanently reduced to the amount set forth opposite such date under
        the heading `Line of Credit,' but only if and to the extent that the
        Line of Credit has not previously been reduced to such amount or less
        pursuant to Section 1.4(a)."

                (c)     The table set forth in Section 1.2(c) of the Credit

        6.      Release of Claims. The Borrower represents and warrants to the
Bank that it has diligently and thoroughly investigated the existence of any
Claim (as defined below) and that, to its knowledge and belief, no Claim exists
and no facts exist that could give rise to or support a Claim. As additional
consideration for the Bank's entering into this letter amendment, the Borrower
and each of its agents, employees, directors, officers, attorneys, affiliates,
subsidiaries, successors and assigns (each a "Releasing Party") hereby release
and forever discharge the Bank and each of its agents, direct and indirect
shareholders, employees, directors, officers, attorneys, branches, affiliates,
subsidiaries, successors and assigns (each a "Released Party") from any and all
damages, losses, claims, demands, liabilities, obligations, actions and causes
of action whatsoever (collectively "Claims") that the Releasing Parties or any
of them may, as of the effective date of this letter amendment, have or claim to
have against any or all of the Released Parties, in each case whether currently
known or unknown or with respect to which the facts are known (or should have
been known), that could give rise to or support a Claim on account of or in any
way relating to, arising out of or based upon any Loan Document, any amendment,
waiver or other modification with respect thereto, the negotiation or
documentation hereof or thereof, any of the transactions contemplated hereby or
thereby, or any action or omission in connection with any of the foregoing,
including all such damages, losses, claims, demands, liabilities, obligations,
actions and causes of action heretofore sustained or that may arise as a
consequence of the dealings between the parties up to the effective date of this
letter amendment in connection with or in any way related to any Loan Document
or any amendment, waiver or other modification with respect thereto. Each
Releasing Party further represents and warrants that it has not heretofore
assigned, and covenants and agrees that it will not hereafter sue any Released
Party upon, any Claim released or purported to be released under this section.
Each Releasing Party will indemnify and hold harmless the Released Parties
against any loss or liability on account of any actions brought by any Releasing
Party or its assigns or prosecuted on behalf of any Releasing Party and relating
to any Claim released or purported to be released under this section. It is
further understood and agreed that any and all rights under the provisions of
Section 1542 of the California Civil Code are expressly waived by each of the
Releasing Parties. Section 1542 of the California Civil Code provides as
follows:

        "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES
        NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING
        THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS
        SETTLEMENT WITH THE DEBTOR."

import referring to the Credit Agreement, and each reference in the other Loan
Documents to "the Credit Agreement," "thereunder,"

<PAGE>

amendment, and (b) each reference in the other Loan Documents to "the Line of

referring to the Line of Credit Note shall mean and be a reference to the new
Line of Credit Note executed by the Borrower in connection with this letter
amendment. The Credit Agreement, as amended by this letter amendment, is and
shall continue to be in full force and effect and is hereby ratified and
confirmed in all respects.

        8.      Execution in Counterparts. This letter amendment may be executed
in any number of counterparts and by the parties hereto in separate
counterparts, each of which counterparts shall be an original and all of which
taken together shall constitute one and the same letter amendment.

        9.      GOVERNING LAW. THIS LETTER AMENDMENT SHALL BE GOVERNED BY, AND
CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF CALIFORNIA
WITHOUT REFERENCE TO THE CHOICE-OF-LAW PRINCIPLES THEREOF.

                                                                   July 31, 2002

        FOR VALUE RECEIVED, the undersigned, STAAR SURGICAL COMPANY, a Delaware
corporation ("Borrower"), promises to pay to the order of WELLS FARGO BANK,
NATIONAL ASSOCIATION, a national banking association ("Bank"), at its office at
333 South Grand Avenue, Los Angeles, California 90071, or at such other place as
the holder hereof may designate, in lawful money of the United States of America
and in immediately available funds, the principal amount of seven million
dollars ($7,000,000.00), or so much thereof as may be advanced and be
outstanding, with interest thereon, to be computed on each advance from the date
of its disbursement as set forth herein.

INTEREST:

        (a)     Interest. The outstanding principal balance of this Note shall
bear interest (computed on the basis of a 360-day year and actual days elapsed)
at a rate per annum equal at all times to the sum of the Prime Rate (as defined
in the Credit Agreement referred to below) in effect from time to time plus the
Applicable Interest Margin (as defined in the Credit Agreement).

        (b)     Payment of Interest. Interest accrued on this Note shall be
payable on the first business day of each calendar month, commencing on April 1,
2002.

        (c)     Default Interest. Upon the occurrence and during the
continuation of any Event of Default (as defined in the Credit Agreement
referred to below), the outstanding principal balance of this Note shall bear
interest until paid in full at an increased rate per annum (computed on the
basis of a 360-day year and actual days elapsed) equal to four percent (4%)
above the rate of interest from time to time otherwise applicable to this Note.

BORROWING AND REPAYMENT:

        (a)     Borrowing and Repayment. Borrower may from time to time during
the term of this Note borrow, partially or wholly repay its outstanding
borrowings, and reborrow, subject to all of the limitations, terms and
conditions of this Note and of the Amended and Restated Credit Agreement dated
as of March 29, 2002, as amended by a First Amendment to Amended and Restated
Credit Agreement dated as of July 31, 2002 (as it may be further amended,
restated or otherwise modified from time to time, the "Credit Agreement"),
between Borrower and Bank and any other document executed in connection with or
governing this Note; provided, however, that the total outstanding borrowings
under this Note shall not at any time exceed the principal amount stated above

balance of this Note at any time shall be the total

payments made hereon by or for Borrower, which balance may be endorsed hereon
from time to time by the holder. The outstanding principal balance of this Note
shall be due and payable in full on March 31, 2003.

        (b)     Advances. Advances hereunder, to the total amount of the
principal amount stated above (subject to reduction as provided in the Credit
Agreement), may be made by the holder at the oral or written request of (i)
those persons who are authorized from time to time by Borrower (as evidenced by
such documents as Bank may require) to request advances and direct the
disposition of any advances, until written notice of the revocation of such
authority is received by the holder at the office designated above, or (ii) any
person, with respect to advances deposited to the credit of any deposit account
of Borrower, which advances, when so deposited, shall be conclusively presumed
to have been made to or for the benefit of Borrower regardless of the fact that
persons other than those authorized to request advances may have authority to
draw against such account. The holder shall have no obligation to determine
whether any person requesting an advance is or has been authorized by Borrower.

        (c)     Application of Payments. Each payment made on this Note shall be
credited, first, to any interest then due and, second, to the outstanding
principal balance hereof.

        This Note is made pursuant to, and is subject to the terms and
conditions of, the Credit Agreement.

        (a)     Remedies. Upon the occurrence of any Event of Default, the
holder of this Note, at the holder's option, may declare all amounts of
principal and interest outstanding hereunder to be immediately due and payable,
without presentment, demand, notice of nonperformance, notice of protest,
protest or notice of dishonor, all of which are expressly waived by Borrower,
and the obligation, if any, of the holder to extend any further credit hereunder
shall immediately cease and terminate. Borrower shall pay to the holder,

entity sign this Note as a Borrower, the obligations of each such Borrower shall
be joint and several.

        (c)     Governing Law. This Note shall be governed by, and construed in
accordance with, the laws of the State of California.

     Re:    Third Amendment to Amended and Restated Credit Agreement

Ladies and Gentlemen:

     We refer to the Amended and Restated Credit Agreement dated as of March 29,
2002, as amended by a First Amendment to Amended and Restated Credit Agreement
dated July 31, 2002 and a Second Amendment to Amended and Restated Credit
Agreement dated October 25, 2002 (said Agreement, as so amended, herein called
the "Credit Agreement") between Staar Surgical Company, a Delaware corporation
(the "Borrower"), and Wells Fargo Bank, National Association, a national banking
association (the "Bank"). Terms defined in the Credit Agreement and not
otherwise defined herein have the same meanings when used herein.

     1. Amendment to Credit Agreement. As of the effective date of this letter
amendment but subject to satisfaction of the terms and conditions specified
herein, Section 4.3(j) of the Credit Agreement is hereby restated in its
entirety as follows:

          "(j) not later than December 13, 2002, projections for fiscal year
     2003; and."

     2. Waiver of Events of Default under Credit Agreement. As of the effective
date of this letter amendment but subject to satisfaction of the terms and
conditions specified herein, the Bank hereby waives (a) the Event of Default
caused by the Borrower's violation of the covenant contained in Section 4.9(c)
of the Credit Agreement with respect to October of 2002 and (b) the Event of
Default expected to be caused by the Borrower's violation of the covenant
contained in Section 4.9(c) of the Credit Agreement with respect to November of
2002.

     3. Representations and Warranties. The Borrower hereby represents and
warrants for the benefit of the Bank that (a) the representations and warranties
of the Borrower contained in the Loan Documents are correct in all material
respects on and as of the effective

<PAGE>

date of this letter amendment, before and after giving effect to the same, as if
made on and as of such date, and (b) no event has occurred and is continuing, or
would result from the effectiveness of this letter amendment, that constitutes
an Event of Default. The Credit Agreement, as modified by this letter amendment,
is and shall continue to be in full force and effect and is hereby ratified and
confirmed in all respects. Except as specifically provided herein, the
execution, delivery and effectiveness of this letter amendment shall not operate
as a waiver of any right, power or remedy of the Bank under any of the Loan
Documents or constitute a waiver of any provision of any of the Loan Documents.

     4. Conditions Precedent. This letter amendment shall become effective as of
the date first set forth above, when and if the Borrower and the Bank execute
counterparts of this letter amendment and deliver them to each other.

     5. Release of Claims. The Borrower represents and warrants to the Bank that
it has diligently and thoroughly investigated the existence of any Claim (as
defined below) and that, to its knowledge and belief, no Claim exists and no
facts exist that could give rise to or support a Claim. As additional
consideration for the Bank's entering into this letter amendment, the Borrower
and each of its agents, employees, directors, officers, attorneys, affiliates,
subsidiaries, successors and assigns (each a "Releasing Party") hereby release
and forever discharge the Bank and each of its agents, direct and indirect
shareholders, employees, directors, officers, attorneys, branches, affiliates,
subsidiaries, successors and assigns (each a "Released Party") from any and all
damages, losses, claims, demands, liabilities, obligations, actions and causes
of action whatsoever (collectively "Claims") that the Releasing Parties or any
of them may, as of the effective date of this letter amendment, have or claim to
have against any or all of the Released Parties, in each case whether currently
known or unknown or with respect to which the facts are known (or should have
been known), that could give rise to or support a Claim on account of or in any
way relating to, arising out of or based upon any Loan Document, any amendment,
waiver or other modification with respect thereto, the negotiation or
documentation hereof or thereof, any of the transactions contemplated hereby or
thereby, or any action or omission in connection with any of the foregoing,
including all such damages, losses, claims, demands, liabilities, obligations,
actions and causes of action heretofore sustained or that may arise as a
consequence of the dealings between the parties up to the effective date of this
letter amendment in connection with or in any way related to any Loan Document
or any amendment, waiver or other modification with respect thereto. Each
Releasing Party further represents and warrants that it has not heretofore
assigned, and covenants and agrees that it will not hereafter sue any Released
Party upon, any Claim released or purported to be released under this section.
Each Releasing Party will indemnify and hold harmless the Released Parties
against any loss or liability on account of any actions brought by any Releasing
Party or its assigns or prosecuted on behalf of any Releasing Party and relating
to any Claim released or purported to be released under this section. It is
further understood and agreed that any and all rights under the provisions of
Section 1542 of the California Civil Code are expressly waived by each of the
Releasing Parties. Section 1542 of the California Civil Code provides as
follows:

     "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT
     KNOW OR SUSPECT TO EXIST IN HIS

<PAGE>

     FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE
     MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR."

     6. Reference to and Effect on Loan Documents. On and after the effective
date of this letter amendment, (a) each reference in the Credit Agreement to
"this Agreement," "hereunder," "hereof," "herein" or words of like import
referring to the Credit Agreement, and each reference in the other Loan
Documents to "the Credit Agreement," "thereunder," "thereof," "therein" or words
of like import referring to the Credit Agreement, shall mean and be a reference
to the Credit Agreement as amended by this letter amendment, and (b) each
reference in the other Loan Documents to "the Line of Credit Note,"
"thereunder," "thereof," "therein" or words of like import referring to the Line
of Credit Note shall mean and be a reference to the new Line of Credit Note
executed by the Borrower in connection with this letter amendment. The Credit
Agreement, as amended by this letter amendment, is and shall continue to be in
full force and effect and is hereby ratified and confirmed in all respects.

     7. Execution in Counterparts. This letter amendment may be executed in any
number of counterparts and by the parties hereto in separate counterparts, each
of which counterparts shall be an original and all of which taken together shall
constitute one and the same letter amendment.

                  [REMAINDER OF PAGE INTENTIONALLY LEFT BLANK.]

     8. GOVERNING LAW. THIS LETTER AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED
AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF CALIFORNIA WITHOUT
REFERENCE TO THE CHOICE-OF-LAW PRINCIPLES THEREOF.

                                           Very truly yours,

                                           WELLS FARGO BANK,
