LASIK can be an eligible medical expense, but your FSA's rules determine which plan year pays, when the service must occur, and when a claim is due. A payment or consultation before December 31 does not automatically make a later operation reimbursable from the current year's balance. Confirm the rules with your plan administrator before committing funds.

Start with a LASIK assessment, not an expiring-balance deadline. Medical suitability and reliable measurements should determine whether and when surgery is reasonable.

Which deadline actually matters?

Separate the service deadline from the claim-submission deadline. A plan may let you submit paperwork after the plan year ends for an expense incurred during that year. That extra paperwork window does not necessarily extend the period in which you can receive the service.

Do not assume every plan follows the calendar year. Ask the administrator for the exact plan-year dates, what counts as an incurred expense for surgery, and which documentation is required. A clinic's payment date is not a substitute for the plan's written answer.

Do unused funds always disappear on December 31?

Not always. Depending on its terms, a health FSA may allow a limited carryover or a grace period. These are different features, and an employer is not required to offer them. Read your own plan documents rather than applying a coworker's rules or an old article's dollar limit.

Ask whether your balance is available, which expenses qualify, and how any carryover or grace period applies to you. This guide does not supply a universal 2026 contribution limit or promise that a specific operation will be reimbursed. Tax eligibility and a particular benefit plan's administration are related but separate questions.

Can you use an FSA even if insurance excludes LASIK?

Insurance coverage and FSA reimbursement are not the same decision. IRS Publication 502 includes qualifying vision-correction surgery among medical expenses. The plan administrator can confirm the documentation and reimbursement requirements for your situation.

Ask for a written estimate and an itemized receipt, and keep them with the plan's response. Our affordability page explains the practice's financial discussion without promising a tax result. A qualified tax adviser or benefits administrator, not a blog, should resolve a disputed eligibility question.

How early should you arrange testing?

Leave room for an examination, a contact-lens break if needed, and repeat measurements if the eye surface or prescription is not stable. A first visit is not a guarantee of surgery or a particular date. If the team recommends postponing treatment, an expiring balance should not reverse that recommendation.

For patients coming to Plano from elsewhere in DFW, allow time for transportation and follow-up as well as the procedure. Ask about scheduling before taking nonrefundable leave or booking travel.

What should you do if time is running out?

Request the plan's rules first, then ask the clinic what is medically and operationally realistic. If the timeline does not fit, discuss future planning rather than compressing necessary care. You may have other eligible expenses or a plan provision worth reviewing with the administrator.

A consultation can establish candidacy; it should not become a promise to spend the balance. The best year-end plan is one that remains sensible even if surgery is not recommended.
