Defined Benefit Plan [Abstract] |
Pension and Other Postretirement Benefits Disclosure [Text Block] | Note 10 — Employee Benefit Plans The Company maintains a passive pension plan (the “Swiss Plan”) covering employees of its Swiss subsidiary, which is accounted for as a defined benefit plan. Defined Benefit Plan-Switzerland In Switzerland employers are required to provide a minimum pension plan for their staff. Contributions of both the employees and employer finance the Swiss Plan. The amount of the contributions is defined by the plan regulations and cannot be decreased without amending the plan regulations. It is required that the employer contribute an amount equal to or greater than the employee contribution. The following table shows the changes in the benefit obligation and plan assets and the Swiss Plan’s funded status as of December 29, 2017 and December 30, 2016 (in thousands):

The amount in accumulated other comprehensive loss as of December 29, 2017 that is expected to be recognized as a component of the net periodic pension costs during fiscal year 2018 is $114,000. Net periodic pension cost and projected and accumulated pension obligation for the Company’s Swiss Plan were calculated on December 29, 2017 and December 30, 2016 using the following assumptions:
|  | 2017 |  | 2016 |
Discount rate |  |  | 0.7 | % |  | 0.8 | %
Salary increases |  |  | 2.0 | % |  | 2.0 | %
Expected return on plan assets |  |  | 2.5 | % |  | 2.5 | %
Expected average remaining working lives in years |  |  | 10.2 |  |  | 10.0 |
The discount rates are based on an assumed duration of the pension obligations and estimated using the rates of returns for AAA and AA-rated Swiss and foreign CHF-denominated corporate bonds listed on the SIX Swiss Exchange. The salary increase rate was based on the Company’s best estimate of future increases over time. The expected long-term rate of return on plan assets is based on the expected asset allocation and assumptions concerning long-term interest rates, inflation rates, and risk premiums for equities above the risk-free rates of return. These assumptions take into consideration historical long-term rates of return for relevant asset categories Under Swiss law, pension funds are legally independent from the employer and all the contributions are invested with regulated entities. The Company has a contract with Allianz Suisse Life Insurance Company’s BVG Collective Foundation (the “Foundation”) to manage its Swiss pension fund. Multiple employers contract with the Foundation to manage the employers’ respective pension plans. The Foundation manages the pension plans of its contracted employers as a collective entity. The investment strategy is determined by the Foundation and applies to all members of the collective Foundation. There are no separate financial statements for each employer contract. The pension plan assets of all the employers that contract with the Foundation are comingled. They are considered multiple-employer plans under ASC 715-30-35-70 and therefore accounted for as single-employer plans. As there are no separate financial statements for each employer contract, there are no individual investments that can be directly attributed to the Company’s pension plan assets. However, the funds contributed by an employer are specifically earmarked for its employees and the total assets of the plan allocable to Company’s employees are separately tracked by the Foundation. The lack of visibility into the specific investments of the plan assets and how they are valued is a significant unobservable input, therefore, the Company considers the plan assets collectively to be Level 3 assets under the fair value hierarchy (see Note 1). The table below sets forth the fair value of Plan assets at December 30, 2016 and December 29, 2017, and the related activity in fiscal years 2016 and 2017, in accordance with ASC 715-20-50-1(d) (in thousands):

Defined Benefit Plan-Japan STAAR Japan maintains a noncontributory defined benefit pension plan (“Japan Plan”) substantially covering all the employees of STAAR Japan. Benefits under the Japan Plan are earned, vested, and accumulated based on a point-system, primarily based on the combination of years of service, actual and expected future grades (management or non-management) and actual and future zone (performance) levels of the employees. Each point earned is worth a fixed monetary value, 1,000 Yen per point, regardless of the level grade or zone of the employee. Gross benefits are calculated based on the cumulative number of points earned over the service period multiplied by 1,000 Yen. The mandatory retirement age limit is 60 years old. STAAR Japan administers the pension plan and funds the obligations of the Japan Plan from STAAR Japan’s operating cash flows. STAAR Japan is not required, and does not intend, to provide contributions to the Plan to meet benefit obligations and therefore does not have any plan assets. Benefit payments are made to beneficiaries as they become due. The funded status of the benefit plan at December 29, 2017 and December 30, 2016 is as follows (in thousands):

The amount in accumulated other comprehensive loss as of December 29, 2017 that is expected to be recognized as a component of the net periodic pension cost in fiscal 2018 is approximately $9,000. Net periodic pension cost and projected and accumulated pension obligation for the Company’s Japan Plan were calculated on December 29, 2017 and December 30, 2016 using the following assumptions:
