                    Certification of Chief Executive Officer
      Pursuant to Rule 13a-14(a) under the Securities Exchange Act of 1934

I, David Liu, the principal executive officer of LaserSight Incorporated certify
that:  1. I have  reviewed  this  quarterly  report on Form 10-QSB of LaserSight
Incorporated;  2. Based on my knowledge, this report does not contain any untrue
statement of a material fact or omit to state a material fact  necessary to make
the statements made, in light of the  circumstances  under which such statements
were made, not misleading with respect to the period covered by this report;  3.
Based on my knowledge, the financial statements, and other financial information
included in this report,  fairly present in all material  respects the financial
condition,  results of  operations  and cash flows of the  registrant as of, and
for, the periods presented in this report; 4. The registrant's  other certifying
officer  and I are  responsible  for  establishing  and  maintaining  disclosure
controls  and  procedures  (as  defined  in  Exchange  Act Rules  13a-15(e)  and
15d-15(e)) and internal control over financial reporting (as defined in Exchange
Act Ruled 13a-15(f) and 15d-15(f)) for the registrant and have:
            a) Designed such disclosure controls and procedures,  or caused such
      disclosure  controls and procedures to be designed under our  supervision,
      to ensure that material information relating to the registrant,  including
      its consolidated subsidiaries,  is made known to us by others within those
      entities,  particularly  during the  period in which this  report is being
      prepared;

            b)  Evaluated  the  effectiveness  of  the  registrant's  disclosure
      controls and procedures and presented in this report our conclusions about
      the effectiveness of the disclosure controls and procedures, as of the end
      of the period covered by this report based on such evaluation; and

            c) Disclosed in this report any change in the registrant's  internal
      controls over financial  reporting that occurred  during the  registrant's
      most recent fiscal quarter that has materially affected,  or is reasonably
      likely to  materially  affect,  the  registrant's  internal  controls over
      financial reporting; and


5. The registrant's other certifying officer and I have disclosed,  based on our
most recent  evaluation of internal  control over  financial  reporting,  to the
registrant's  auditors  and the audit  committee  of the  registrant's  board of
directors (or persons performing the equivalent functions):

            a) All  significant  deficiencies  and  material  weaknesses  in the
      design or operation of internal  controls over financial  reporting  which
      are  reasonably  likely to adversely  affect the  registrant's  ability to
      record, process, summarize and report financial information; and

            b) Any fraud,  whether or not material,  that involves management or
      other employees who have a significant role in the  registrant's  internal
      controls over financial reporting.
