                                       Vice President, Investor Relations

                    TLCVISION REPORTS Q1-04 FINANCIAL RESULTS

TORONTO, ONTARIO--(May 10, 2004) - TLC Vision Corporation (NASDAQ:TLCV;
TSX:TLC), North America's premier eye care services company, today announced its
financial results for the three month period ended March 31, 2004. All dollar
amounts are expressed in U.S. currency and results are reported in accordance
with U.S. generally accepted accounting principles (U.S. GAAP) unless otherwise
stated.

Q1-04 total net revenues were $65.2 million, up 22% from $53.6 million in Q1-03
and up 34% from $48.5 million in the previous quarter.

First quarter total paid laser procedure volumes were over 56,800. Procedure
volumes include procedures of a former subsidiary that became an equity
investment in 2004. Same-store year-over-year volume growth of 16% in the
centers was partially offset by the closing of unprofitable centers and lower,
but still positive, 4% year-over-year volume growth in the access business. The
result was that Q1-04 procedure volumes were up 6% from the 53,500 reported in
the same three month period a year ago and represented an increase of 47%
sequentially from the 38,600 refractive procedures performed last quarter. The
procedure volume mix in Q1-04 was 58% centers versus 42% access. Custom LASIK
procedures represented approximately 49% of owned or managed center volumes in
Q1-04.

On a GAAP basis, TLCVision reported a Q1-04 net profit of $8.1 million or $0.12
per share. This represents more than a 7-fold increase from $1.1 million or
$0.02 per share for the same three month period a year ago, and compares to a
loss of ($2.9 million) or ($0.04) per share last quarter. First quarter 2004
adjusted EBITDA was $13.3 million, up 88% from the $7.1 million for the same
period last year and an increase of 237% from $3.9 million in Q4-03.

[Adjusted EBITDA is defined as earnings before interest, taxes, depreciation and
amortization ("EBITDA") excluding certain non-recurring items and research and
development costs and is used to assist in understanding and comparing operating
results. EBITDA and Adjusted EBITDA, which are not calculated identically by all
companies, are not substitutes for operating income, net income and cash flow as
determined in accordance with generally accepted accounting principles.
Management uses EBITDA and Adjusted EBITDA as key measures of operating
performance. Reference should be made to the "Adjusted EBITDA" table that
provides reconciliation between operating results as prescribed by U.S. GAAP and
"Adjusted EBITDA".]


Elias Vamvakas, TLCVision's Chairman & CEO, commented "I believe that our
operations team did an outstanding job in preparing TLCVision to capitalize so
well financially on procedure volume growth in the seasonally strong first
quarter. Year-over-year growth trends improved throughout the first quarter and
that momentum has so far continued into Q2. Indeed, April 2004 total paid laser
procedure volumes were up more than 20% from April 2003 levels. I am very
pleased with what we have accomplished thus far and am confident that we will
continue to build on TLCVision's world-leading position going forward."
