                       September 30, 1998

Note A

Inventories at September 30, 1998 and March 31, 1998 consisted
of:
                          September 30     March 31
                                 (In thousands)

                         $    50,674    $    44,632

Note B

Other assets at September 30, 1998 include the Company's equity
investments in its marketing partners, Intracel Corporation and
North American Scientific, Inc. (NASI).  The Intracel Corporation
investment is valued at cost of $6 million.  In accordance with
Financial Accounting Standards Board (FASB) statement 115
"Accounting of Certain Equity Investments in Debt and Equity
Securities" the North American Scientific investment is carried
at its fair market value of approximately $2.6 million.
Unrealized gains, net of the related tax effect, are accounted
for as a separate component of shareholders' equity.

Note C

In 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 128, "Earnings
per Share".  Statement 128 replaced the previously reported
primary and fully diluted earnings per share with basic and
diluted earnings per share.  Unlike primary earnings per share,
basic earnings per share excludes any dilutive effects of
options, warrants, and convertible securities.  Diluted earnings
per share is very similar to the previously reported fully
diluted earnings per share.  All earnings per share amounts for
all periods have been restated to conform to Statement 128
requirements.

Note D

The Company has adopted Statement of Financial Accounting
Standards No. 130 "Reporting Comprehensive Income" ("SFAS 130").
SFAS 130 establishes standards for reporting and display of an
alternative income measurement and its components (revenue,
expenses, gains and losses) in a full set of general purpose
financial statements.  The total comprehensive income for the six
months ended September 30, 1998 is $9.1 million, compared with
$10.5 million for the same period a year ago.  Total
comprehensive income includes net earnings, net unrealized
currency gains and losses on translation and net unrealized gains
and losses on securities.

Note E

The amounts set forth in the accompanying statements are
unaudited but, in the opinion of management, reflect all
adjustments (consisting only of normal accruals) necessary for a
fair statement of the results of operations for the periods
presented.  Operating results for the six months period ended
September 30, 1998 are not necessarily indicative of the results
that may be expected for the year ended March 31, 1999.  It is
suggested that the condensed consolidated financial statements
included herein be read in conjunction with the Company's annual
report on form 10-K for the year ended March 31, 1998.

Note F

The Company's three quarterly interim reporting periods are each
approximately thirteen week periods ending on the Friday nearest
the end of the third calendar month.  The fiscal year end remains
March 31.  To facilitate ease of presentation, each interim
period is shown as if it ended on the last day of the appropriate
calendar month.  The actual dates on which each quarter ended are
shown below:

RESULTS OF OPERATIONS

Sales

Sales for the three months ended September 30, 1998 increased 16%
to $56.7 million, compared to $48.8 million the prior year.
Growth was strong in sales of all product categories. Plastic and
general surgery sales were up 21%. General surgery sales
increased over 100%. The Company's Contour Genesis product was
introduced at the end of the second quarter last year. Urology
products increased 11% compared to a year ago. Adding to urology
product sales were two new products that were introduced in the
last year: brachytherapy seeds for the treatment of prostate
cancer, and the Suspend sling for treating female urinary
incontinence. Both product lines showed good growth from the
immediately preceding quarter. Penile implant sales, while still
below last year, also showed strong sequential growth from the
June 1998 quarter. These sales had been affected in that quarter
by the introduction of a new impotence drug, Viagra. The
combination of ease of use, plus a major advertising campaign
from Pfizer, generated an unprecedented amount of interest in
this new product.  The Company believes that this interest in
treating impotence bodes well for the long term prospects of
penile implant sales, as Viagra will not work on all patients.
However, we may continue to see weakness in sales in the next few
quarters. Ophthalmic product sales increased 12%.  Continued
success of the MemoryLens, a foldable intraocular lens, helped
offset declines in fixed intraocular lenses and diagnostic
products. The MemoryLens was approved for sale in the United
States in December 1997.

Cost of Sales

Cost of sales was 38.5% for the three months ended September 30,
1998 compared to 42.0% for the same period last year. The
increase in the cost of sales in the second quarter last year was
primarily related to a fire at the Texas manufacturing facility.
Several production departments were shut down for the month of
September, either for cleanup and repair or due to lack of
production from the fire affected departments. The high level of
cost of sales was primarily caused by the write-off of lost
inventory and unabsorbed overhead due to a lack of production,
combined with the lower sales in the quarter.

Included in Cost of Sales this period was approximately $550
thousand in proceeds from the Company's insurance claim related
to the fire. In addition, the Company continues to incur a
substantial amount of expense related to the ongoing re-
validation efforts at the Texas plant.

In 1996, the Food and Drug Administration (FDA) issued the Texas
facility a warning letter, citing several inadequacies in the
Company's adherence to FDA Good Manufacturing Practices (GMP).
The FDA was specifically concerned with the method by which the
Company had performed its initial validation of the manufacturing
processes in the Texas facility.  The Company agreed to re-
validate the facility, as well as correct the other items in the
warning letter, and in July, 1996, submitted to the FDA a
schedule for completion of these items.  In August 1997, the FDA
returned to the Texas facility to perform a comprehensive GMP
compliance audit, which included reviewing the Company's progress
in completing the remaining items contained in the 1996 warning
letter.  While the Company had completed a substantial amount of
items, the re-validation effort had not been completed within the
time frame outlined in the July 1996 schedule.

In May 1998, the Company entered into a voluntary consent decree
with the FDA in relation to the Texas facility.  The agreement
requires, under a schedule agreed to by the Company and the FDA,
the completion of the re-validations of certain of the Company's
manufacturing processes, strengthening of its continuous quality
improvement program, and an independent audit on overall GMP
compliance.

More specifically, the consent decree calls for the Company to
hire outside expert consultants to assist in strengthening the
Company's compliance program and related processes.  By July 5,
1998 the consultant was required to conduct a comprehensive GMP
audit of the Texas facility and submit a detailed written report
to Mentor management and the FDA on its findings.  In that
report, which was submitted on time, the consultant stated that,
except for the outstanding re-validations, there were no
significant areas of GMP non-compliance. Under the terms of the
consent decree, the consultant is required to conduct an
inspection and to issue a report annually.

Further, the Company was required to establish stronger
procedures for continuous corrective action programs.  The
consultant was to report to management and to the FDA as to
whether such a program had been instituted.  On July 14, 1998 the
expert consultant reported to management and to the FDA that such
a program had been designed and was being implemented by the
Company.

The Company and FDA agreed to time frames under which the Company
is to complete its re-validations of its manufacturing processes;
specifically by November 2, 1998 for saline-filled devices and by
December 31, 1998 for gel-filled devices.  The Company completed
its validation of saline-filled devices by November 2.  The
outside expert consultant reviewed such validations and reported
to management and to the FDA that all validation projects have
been completed for all seven RTV product families in accordance
with established milestones and within the timeframes established
by the consent decree.  Further the consultant stated in his
report in summary, it is my opinion that the PQ (process
qualification) and PPQ (product process qualification) and their
execution is consistent with Mentor Texas internal operating
procedures, industry practice and FDA requirements.  Validation
results met all acceptance criteria set forth in the protocols.

The Company believes that it will meet the remaining milestones
as set forth in the consent decree, although there can be no
absolute assurance that it can do so.  In addition, although the
expert consultants have expressed their opinion as to the
satisfactory completion of certain consent decree requirements,
FDA inspectors, during some future audit, may disagree with the
conclusions of these experts.  Should the Company fail to comply
with the conditions of the consent decree, under its terms the
FDA is allowed to order the Company to stop manufacturing or
distributing the breast implants, order a recall or take other
corrective actions.  The Company may also be subject to penalties
of $10,000 per day until the task is completed.

Selling, General and Administrative Expenses

Selling, general and administrative expenses were 39.8% of sales
in the quarter compared to 39.3% in the previous year.  The
increase relates primarily to the Company's efforts in launching
its new products, including the MemoryLens, brachytherapy seeds
and the Suspend sling.  The Company is increasing its marketing
and sales staff to accommodate these new products.

Research and Development

Research and development expenses were 7.5% of sales for the
quarter, compared to 9.9% for the prior year.  In the prior year,
the Company had spent funds on the completion of the development
of the Contour Genesis, which was introduced in September 1997.
The Company continues to spend substantial funds on its premarket
approval applications ("PMAAs") for its saline breast implants,
silicone gel filled breast implants, and penile implants.  The
Company is committed to a variety of clinical and laboratory
studies in connection with these products.  The Company expects
to complete the work on its saline filled breast implant PMAAs
and submit the data to the FDA by the end of fiscal 1999.  Other
major studies underway include an alternate filler breast implant
and extending the use of the Contour Genesis to include
liposuction.

Interest and Other Income and Expense

Net interest income decreased from $376 thousand last year to
$275 thousand this year, resulting from lower cash balances.

Income Taxes

The effective rate of corporate income taxes was 32.0% for the
quarter, compared to 34.2% in the same period a year ago.  The
decrease results from higher expected income from our tax-
advantaged facility in Puerto Rico, which makes the MemoryLens.

Net Income

Diluted earnings per share was $.22 for the three months ended
September 30, 1998, compared to $.12 the prior year. The increase
was due to higher sales, combined with lower cost of sales, due
to the fire last year.

LIQUIDITY AND CAPITAL RESOURCES

At September 30, 1998, the Company's working capital was $83.6
million compared to $94.9 million at March 31, 1998.  The
Company's working capital needs were provided from operations and
borrowings under its line of credit.

The Company generated $12.7 million of cash from operations
during the three months ended September 30, 1998, compared to
$15.3 million the previous year.  Higher net income in the
current period was offset by increased levels of accounts
receivable and inventory when compared to the prior year.

The Company anticipates investing approximately $15 million in
facilities and capital equipment in fiscal 1999.  The majority of
the expenditures will be for facility upgrades at the Company's
manufacturing facilities in Texas and Minneapolis, as well as for
enhancing the Company's information technology capabilities.

For the last several years, the Company has paid a quarterly cash
dividend of $.025 per share.  At the indicated rate of $.10 per
year, the aggregate annual dividend would equal approximately
$2.5 million.

The Company's Board of Directors has authorized an ongoing stock
repurchase program.  The objectives of the program, among other
items, are to offset the issuance of stock options, provide
liquidity to the market and to reduce the overall number of
shares outstanding.  Repurchases are subject to market conditions
and cash availability.  In July 1998, the Board increased the
repurchase authorization by 1 million shares, to a total of 1.8
million, and instructed the Company to increase its share
repurchases.  As a result, during the second quarter of fiscal
1999 the Company repurchased 1.1 million shares for consideration
of $19.9 million.

During the quarter, the Company renegotiated its bank line of
credit to increase the maximum borrowing amount from $15 million
to $25 million. It also lowered the annual commitment fee from
 .25% to .125% on the unused portion of the line. As a result of
the increased stock repurchase program, the Company borrowed $5.1
million under the line of credit during the quarter. This amount
was outstanding as of September 30, 1998.

The Company's principal source of liquidity at September 30, 1998
consisted of $14 million in cash and marketable securities plus
$19.9 million available under its line of credit.


IMPACT OF YEAR 2000

General Description of the Year 2000 Issue and the Nature and
Effects of the Year 2000 on Information Technology (IT) and Non-
IT Systems

The Year 2000 Issue is the result of computer programs being
written using two digits rather than four to define the
applicable year.  Any of the Company's computer programs or
hardware that have date-sensitive software or embedded chips may
recognize a date using "00" as the year 1900 rather than the year
2000.  This could result in a system failure or miscalculations
causing disruptions of operations, including, among other things,
a temporary inability to process transactions, send invoices, or
engage in similar normal business activities.

Based on recent assessments, the Company determined that it will
be required to modify or replace portions of its distribution,
finance and manufacturing software and certain hardware so that
those systems will properly utilize dates beyond December 31,
1999.  The Company presently believes that with modifications or
replacements of certain existing software and hardware, the Year
2000 Issue can be mitigated.  However, if such modifications and
replacements are not made, or are not completed in a timely
manner, the Year 2000 Issue could have a material impact on the
operations of the Company.

The Company's plan to resolve the Year 2000 Issue involves the
following key phases: inventory, assessment and remediation.  The
Company has categorized its systems into several areas: core
systems (i.e. distribution, finance and manufacturing systems),
ancillary support systems to those core systems, embedded
systems, products, and third party vendors.

Inventory and Assessment

The Company has completed its inventory and assessment of its
domestic core systems, indicating most of the core systems would
be adversely affected. The Company has completed the inventory of
its international sales office systems, and expects to complete
the assessment of those systems by January 31, 1999.  The Company
expects to complete the inventory and assessment of its other
areas (other than its products) by January 31, 1999.  The Company
has completed its inventory and assessment of its product lines
and has determined that most of the products it has sold and will
continue to sell do not require remediation to be Year 2000
compliant.  Accordingly, the Company does not believe that the
Year 2000 presents a material exposure as it relates to the
Company's products.

Status of Progress in Becoming Year 2000 Compliant

For its domestic core system exposures, to date the Company is
75% complete on the remediation phase and expects to complete
software reprogramming and/or replacement no later than March 31,
1999.

The remediation of embedded systems is significantly more
difficult than the remediation of the core systems.  The
inventory and assessment of embedded systems is expected to be
complete by January 31, 1999. Based on its assessment, the
Company will begin any necessary remediation shortly thereafter.

Nature and Level of Importance of Third Parties and their
Exposure to the Year 2000

Other than payroll and its banking relationships, the Company has
no other significant direct interfaces with third party vendors.
The Company is in the process of working with key third party
vendors to ensure that the Company's systems that interface
directly with third party vendors are Year 2000 compliant by
December 31, 1999.  The Company understands that key vendors are
in the process of making their systems Year 2000 compliant.  Each
vendor queried by the Company believed that its system would be
Year 2000 compliant by the end of 1999.

The Company is beginning to query its significant suppliers and
subcontractors that do not share information systems with the
Company (external agents).  To date, the Company is not aware of
any external agent with a Year 2000 issue that would materially
impact the Company's results of operations, liquidity, or capital
resources.  The Company has no means of ensuring that external
agents will be Year 2000 ready.  The inability of external agents
to complete their Year 2000 resolution process in a timely
fashion could materially impact the Company.  The effect of non-
compliance by external agents is not determinable at this time.

Costs

The total cost to the Company of the Year 2000 project is
estimated at $4.0 million and is being funded through operating
cash flows.  To date, the Company has incurred costs of
approximately $1.2 million. This amount includes upgrading its
desktop systems and office software to the latest release, which
the Company would do in the normal course of business. The
majority of these costs relate to new hardware and software and
are being capitalized.

Risks

Management of the company believes it has an effective program in
place to resolve the Year 2000 issue in a timely manner.  The
Company has not yet completed all necessary phases of the Year
2000 program.  In the event that the Company does not complete
any additional phases, the Company would be constrained in taking
customer orders, and might be unable to manufacture and ship
certain products, or invoice customers.  In addition, disruptions
in the economy generally resulting from Year 2000 issues could
also materially adversely affect the Company.

Contingency Plans

The Company currently has no contingency plans in place in the
event it does not complete all phases of the Year 2000 program.
The Company plans to evaluate the status of completion in March
1999 and determine whether such a plan is necessary.
