                               REFOCUS GROUP, INC.

                        WARRANT TO PURCHASE COMMON STOCK


                     VOID AFTER 5:30 P.M., EASTERN STANDARD
                          TIME, ON THE EXPIRATION DATE

THIS WARRANT AND ANY SHARES ACQUIRED UPON THE EXERCISE OF THIS WARRANT HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND
MAY NOT BE SOLD, PLEDGED, HYPOTHECATED, DONATED OR OTHERWISE TRANSFERRED WITHOUT
COMPLIANCE WITH THE REGISTRATION OR QUALIFICATION PROVISIONS OF APPLICABLE
FEDERAL AND STATE SECURITIES LAWS OR APPLICABLE EXEMPTIONS THEREFROM.

         FOR VALUE RECEIVED, Refocus Group, Inc., a Delaware corporation (the
"Company"), hereby agrees to sell upon the terms and on the conditions
hereinafter set forth, but no later than 5:30 p.m., Eastern Standard Time, on
the Expiration Date (as hereinafter defined) to _____________ or registered
assigns (the "Holder"), under the terms as hereinafter set forth, ____________
fully paid and non-assessable shares of the Company's Common Stock, par value
$.0001 per share (the "Warrant Stock"), at a purchase price per share of Two and
50/100 Dollars ($2.50) (the "Warrant Price"), pursuant to this warrant (this
"Warrant"). The number of shares of Warrant Stock to be so issued and the
Warrant Price are subject to adjustment in certain events as hereinafter set
forth. The term "Common Stock" shall mean, when used herein, unless the context
otherwise requires, the stock and other securities and property at the time
receivable upon the exercise of this Warrant.

         This Warrant is one of a series of the Company's Warrants to purchase
Common Stock (collectively, the "Warrants"), issued pursuant to that certain
Confidential Private Placement Memorandum, dated October 15, 2002, as
supplemented (the "Memorandum"). Capitalized terms used and not otherwise
defined herein shall have the respective meanings attributed thereto in Section
10.

         1.       EXERCISE OF WARRANT.

         (a) The Holder may exercise this Warrant according to its terms by
surrendering this Warrant to the Company at the address set forth in Section 11,
the subscription form attached hereto having then been duly executed by the
Holder, accompanied by cash, certified check or bank draft in payment of the
purchase price, in lawful money of the United States of America, for the number
of shares of the Warrant Stock specified in the subscription form, or as
otherwise provided in this Warrant prior to 5:30 p.m., Eastern Standard Time, on
March 6, 2006 (the "Expiration Date").

<Page>

         (b) This Warrant may be exercised in whole or in part so long as any
exercise in part hereof would not involve the issuance of fractional shares of
Warrant Stock. If exercised in part, the Company shall deliver to the Holder a
new Warrant, identical in form, in the name of the Holder, evidencing the right
to purchase the number of shares of Warrant Stock as to which this Warrant has
not been exercised, which new Warrant shall be signed by the Chairman and Chief
Executive Officer or the President and the Secretary or the Assistant Secretary
of the Company. The term Warrant as used herein shall include any subsequent
Warrant issued as provided herein.

         (c) No fractional shares or scrip representing fractional shares shall
be issued upon the exercise of this Warrant. The Company shall pay cash in lieu
of fractions with respect to the Warrants based upon the fair market value of
such fractional shares of Common Stock (which shall be the closing price of such
shares on the exchange or market on which the Common Stock is then traded) at
the time of exercise of this Warrant.

         (d) In the event of any exercise of the rights represented by this
Warrant, a certificate or certificates for the Warrant Stock so purchased,
registered in the name of the Holder, shall be delivered to the Holder within a
reasonable time after such rights shall have been so exercised. The person or
entity in whose name any certificate for the Warrant Stock is issued upon
exercise of the rights represented by this Warrant shall for all purposes be
deemed to have become the holder of record of such shares immediately prior to
the close of business on the date on which the Warrant was surrendered and
payment of the Warrant Price and any applicable taxes was made, irrespective of
the date of delivery of such certificate, except that, if the date of such
surrender and payment is a date when the stock transfer books of the Company are
closed, such person shall be deemed to have become the holder of such shares at
the opening of business on the next succeeding date on which the stock transfer
books are open. Except as provided in Section 4 hereof, the Company shall pay
any and all documentary stamp or similar issue or transfer taxes payable in
respect of the issue or delivery of shares of Common Stock on exercise of this
Warrant.

         2.       DISPOSITION OF WARRANT STOCK AND WARRANT.

         (a) The Holder hereby acknowledges that this Warrant and any Warrant
Stock purchased pursuant hereto are not being registered (i) under the Act on
the ground that the issuance of this Warrant is exempt from registration under
Section 4(2) of the Act as not involving any public offering or (ii) under any
applicable state securities law because the issuance of this Warrant does not
involve any public offering; and that the Company's reliance on the Section 4(2)
exemption of the Act and under applicable state securities laws is predicated in
part on the representations hereby made to the Company by the Holder that it is
acquiring this Warrant and will acquire the Warrant Stock for investment for its
own account, with no present intention of dividing its participation with others
or reselling or otherwise distributing the same, subject, nevertheless, to any
requirement of law that the disposition of its property shall at all times be
within its control.

                                       2
<Page>

         The Holder hereby agrees that it will not sell or transfer all or any
part of this Warrant and/or Warrant Stock unless and until it shall first have
given notice to the Company describing such sale or transfer and furnished to
the Company either (i) an opinion, reasonably satisfactory to counsel for the
Company, of counsel (skilled in securities matters, selected by the Holder and
reasonably satisfactory to the Company) to the effect that the proposed sale or
transfer may be made without registration under the Act and without registration
or qualification under any state law, or (ii) an interpretative letter from the
Securities and Exchange Commission to the effect that no enforcement action will
be recommended if the proposed sale or transfer is made without registration
under the Act.

         (b) If, at the time of issuance of the shares issuable upon exercise of
this Warrant, no registration statement is in effect with respect to such shares
under applicable provisions of the Act, the Company may at its election require
that the Holder provide the Company with written reconfirmation of the Holder's
investment intent and that any stock certificate delivered to the Holder of a
surrendered Warrant shall bear legends reading substantially as follows:

                  "TRANSFER OF THE SHARES REPRESENTED BY THIS CERTIFICATE IS
                  SUBJECT TO CERTAIN RESTRICTIONS SET FORTH IN THE WARRANT
                  PURSUANT TO WHICH THESE SHARES WERE PURCHASED FROM THE
                  COMPANY. COPIES OF THOSE RESTRICTIONS ARE ON FILE AT THE
                  PRINCIPAL OFFICES OF THE COMPANY, AND NO TRANSFER OF SUCH
                  SHARES OR OF THIS CERTIFICATE, OR OF ANY SHARES OR OTHER
                  SECURITIES (OR CERTIFICATES THEREFOR) ISSUED IN EXCHANGE FOR
                  OR IN RESPECT OF SUCH SHARES, SHALL BE EFFECTIVE UNLESS AND
                  UNTIL THE TERMS AND CONDITIONS THEREIN SET FORTH SHALL HAVE
                  BEEN COMPLIED WITH."

                  "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AND MAY NOT BE
                  SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF IN THE
                  ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
                  SECURITIES ACT OF 1933 OR AN OPINION OF COUNSEL SATISFACTORY
                  TO THE ISSUER OF THIS CERTIFICATE THAT REGISTRATION IS NOT
                  REQUIRED UNDER SAID ACT."

In addition, so long as the foregoing legend may remain on any stock certificate
delivered to the Holder, the Company may maintain appropriate "stop transfer"
orders with respect

                                       3
<Page>

to such certificates and the shares represented thereby on its books and records
and with those to whom it may delegate registrar and transfer functions.

         3. RESERVATION OF SHARES. The Company hereby agrees that at all times
there shall be reserved for issuance upon the exercise of this Warrant such
number of shares of its Common Stock as shall be required for issuance upon
exercise of this Warrant. The Company further agrees that all shares which may
be issued upon the exercise of the rights represented by this Warrant will be
duly authorized and will, upon issuance and against payment of the exercise
price, be validly issued, fully paid and non-assessable, free from all taxes,
liens, charges and preemptive rights with respect to the issuance thereof, other
than taxes, if any, in respect of any transfer occurring contemporaneously with
such issuance and other than transfer restrictions imposed by federal and state
securities laws.

         4. EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT. This Warrant is
exchangeable, without expense, at the option of the Holder, upon presentation
and surrender hereof to the Company or at the office of its stock transfer
agent, if any, for other Warrants of different denominations, entitling the
Holder or Holders thereof to purchase in the aggregate the same number of shares
of Common Stock purchasable hereunder. Upon surrender of this Warrant to the
Company or at the office of its stock transfer agent, if any, with the
Assignment Form annexed hereto duly executed and funds sufficient to pay any
transfer tax, the Company shall, without charge, execute and deliver a new
Warrant in the name of the assignee named in such instrument of assignment and
this Warrant shall promptly be canceled. This Warrant may be divided or combined
with other Warrants that carry the same rights upon presentation hereof at the
office of the Company or at the office of its stock transfer agent, if any,
together with a written notice specifying the names and denominations in which
new Warrants are to be issued and signed by the Holder hereof.

         5.  CAPITAL ADJUSTMENTS.  This Warrant is subject to the following
further provisions:

         (a) RECAPITALIZATION, RECLASSIFICATION AND SUCCESSION. If any
recapitalization of the Company or reclassification of its Common Stock or any
merger or consolidation of the Company into or with a corporation or other
business entity, or the sale or transfer of all or substantially all of the
Company's assets or of any successor corporation's assets to any other
corporation or business entity (any such corporation or other business entity
being included within the meaning of the term "successor corporation") shall be
effected, at any time while this Warrant remains outstanding and unexpired,
then, as a condition of such recapitalization, reclassification, merger,
consolidation, sale or transfer, lawful and adequate provision shall be made
whereby the Holder of this Warrant thereafter shall have the right to receive
upon the exercise hereof as provided in Section 1 and in lieu of the shares of
Common Stock immediately theretofore issuable upon the exercise of this Warrant,
such shares of capital stock, securities or other property as may be issued or
payable with respect to or in exchange for a number of outstanding shares of
Common Stock equal to the number of shares of Common Stock immediately
theretofore issuable upon the exercise of this Warrant immediately prior to such
recapitalization,

                                       4
<Page>

reclassification, merger, consolidation, sale or transfer, and in each such
case, the terms of this Warrant shall be applicable to the shares of stock or
other securities or property receivable upon the exercise of this Warrant after
such consummation.

         (b) SUBDIVISION OR COMBINATION OF SHARES. If the Company at any time
while this Warrant remains outstanding and unexpired shall subdivide or combine
its Common Stock, the number of shares of Warrant Stock purchasable upon
exercise of this Warrant and the Warrant Price shall be proportionately
adjusted.

         (c) STOCK DIVIDENDS AND DISTRIBUTIONS. If the Company at any time while
this Warrant is outstanding and unexpired shall issue or pay the holders of its
Common Stock, then (i) the Warrant Price shall be adjusted in accordance with
Section 5(e) and (ii) the number of shares of Warrant Stock purchasable upon
exercise of this Warrant shall be adjusted to the number of shares of Common
Stock that Holder would have owned immediately following such action had this
Warrant been exercised immediately prior thereto.

         If the Company shall at any time after the date of issuance of this
Warrant distribute to all holders of its Common Stock any shares of capital
stock of the Company (other than Common Stock) or evidences of its indebtedness
or assets (excluding cash dividends or distributions paid from retained earnings
or current year's or prior year's earnings of the Company) or rights or warrants
to subscribe for or purchase any of its securities (excluding those referred to
in the immediately preceding paragraph) (any of the foregoing being hereinafter
in this paragraph called the "Securities"), then in each such case, the Company
shall reserve shares or other units of such securities for distribution to the
Holder upon exercise of this Warrant so that, in addition to the shares of the
Common Stock to which such Holder is entitled, such Holder will receive upon
such exercise the amount and kind of such Securities which such Holder would
have received if the Holder had, immediately prior to the record date for the
distribution of the Securities, exercised this Warrant.

         (d) WARRANT PRICE ADJUSTMENT. Whenever the number of shares of Warrant
Stock purchasable upon exercise of this Warrant is adjusted, as herein provided,
the Warrant Price payable upon the exercise of this Warrant shall be adjusted to
that price determined by multiplying the Warrant Price immediately prior to such
adjustment by a fraction (i) the numerator of which shall be the number of
shares of Warrant Stock purchasable upon exercise of this Warrant immediately
prior to such adjustment, and (ii) the denominator of which shall be the number
of shares of Warrant Stock purchasable upon exercise of this Warrant immediately
thereafter.

         (e) CERTAIN SHARES EXCLUDED. The number of shares of Common Stock
outstanding at any given time for purposes of the adjustments set forth in this
Section 5 shall exclude any shares then directly or indirectly held in the
treasury of the Company.

         (f) DEFERRAL AND CUMULATION OF DE MINIMIS ADJUSTMENTS. The Company
shall not be required to make any adjustment pursuant to this Section 5 if the
amount of such adjustment would be less than one percent (1%) of the Warrant
Price in effect

                                       5
<Page>

immediately before the event that would otherwise have given rise to such
adjustment. In such case, however, any adjustment that would otherwise have been
required to be made shall be made at the time of and together with the next
subsequent adjustment which, together with any adjustment or adjustments so
carried forward, shall amount to not less than one percent (1%) of the Warrant
Price in effect immediately before the event giving rise to such next subsequent
adjustment.

         (g) DURATION OF ADJUSTMENT. Following each computation or readjustment
as provided in this Section 5, the new adjusted Warrant Price and number of
shares of Warrant Stock purchasable upon exercise of this Warrant shall remain
in effect until a further computation or readjustment thereof is required.

         6.       NOTICE TO HOLDERS.

                  (a)      NOTICE OF RECORD DATE.  In case:

                           (i) the Company shall take a record of the holders of
                  its Common Stock (or other stock or securities at the time
                  receivable upon the exercise of this Warrant) for the purpose
                  of entitling them to receive any dividend (other than a cash
                  dividend payable out of earned surplus of the Company) or
                  other distribution, or any right to subscribe for or purchase
                  any shares of stock of any class or any other securities, or
                  to receive any other right;

                           (ii) of any capital reorganization of the Company,
                  any reclassification of the capital stock of the Company, any
                  consolidation with or merger of the Company into another
                  corporation, or any conveyance of all or substantially all of
                  the assets of the Company to another corporation; or

                           (iii) of any voluntary dissolution, liquidation or
                  winding-up of the Company;

then, and in each such case, the Company will mail or cause to be mailed to the
Holder hereof at the time outstanding a notice specifying, as the case may be,
(i) the date on which a record is to be taken for the purpose of such dividend,
distribution or right, and stating the amount and character of such dividend,
distribution or right, or (ii) the date on which such reorganization,
reclassification, consolidation, merger, conveyance, dissolution, liquidation or
winding-up is to take place, and the time, if any, is to be fixed, as of which
the holders of record of Common Stock (or such stock or securities at the time
receivable upon the exercise of this Warrant) shall be entitled to exchange
their shares of Common Stock (or such other stock or securities) for securities
or other property deliverable upon such reorganization, reclassification,
consolidation, merger, conveyance, dissolution or winding-up. Such notice shall
be mailed at least fifteen (15) days prior to the record date therein specified,
or if no record date shall have been specified therein, at least thirty (30)
days prior to such specified date.

                  (b) CERTIFICATE OF ADJUSTMENT. Whenever any adjustment shall
be made pursuant to Section 5 hereof, the Company shall promptly make a
certificate signed by its

                                       6
<Page>

Chairman and Chief Executive Officer, its President or a Vice President and by
its Treasurer or Assistant Treasurer or its Secretary or Assistant Secretary,
setting forth in reasonable detail the event requiring the adjustment, the
amount of the adjustment, the method by which such adjustment was calculated and
the Warrant Price and number of shares of Warrant Stock purchasable upon
exercise of this Warrant after giving effect to such adjustment, and shall
promptly cause copies of such certificates to be mailed (by first class mail,
postage prepaid) to the Holder of this Warrant.

         7. LOSS, THEFT, DESTRUCTION OR MUTILATION. Upon receipt by the Company
of evidence satisfactory to it, in the exercise of its reasonable discretion, of
the ownership and the loss, theft, destruction or mutilation of this Warrant
and, in the case of loss, theft or destruction, of indemnity reasonably
satisfactory to the Company and, in the case of mutilation, upon surrender and
cancellation thereof, the Company will execute and deliver in lieu thereof,
without expense to the Holder, a new Warrant of like tenor dated the date
hereof.

         8. WARRANT HOLDER NOT A STOCKHOLDER. The Holder of this Warrant, as
such, shall not be entitled by reason of this Warrant to any rights whatsoever
as a stockholder of the Company.

         9. REGISTRATION RIGHTS. This Warrant and the shares of Common Stock
issuable upon exercise of this Warrant will be accorded the registration rights
under the Act set forth in that certain Subscription Agreement between the
Company and the Holders, a form of which agreement is being furnished
concurrently herewith.
