Preparing for LASIK surgery mostly means following your clinic's instructions: stopping contact lens wear for a set period beforehand, arranging transportation and time off, avoiding eye makeup and creams on procedure day, and confirming costs and aftercare plans in advance. Good preparation reduces day-of stress and supports a smooth recovery.
Start With Your Clinic's Instructions
Every clinic provides its own pre-operative instructions, and those instructions take precedence over anything you read online — including this guide. Protocols differ: the required contact-lens-free period, which medications to pause or continue, arrival times, and fasting rules (usually not required for LASIK, but confirm) all vary by provider. This article covers the common themes so you know what to expect and what to ask about, but treat your clinic's written instructions as the final word.
If anything in the clinic's instructions is unclear, call and ask rather than guessing. Pre-operative teams answer these questions routinely, and a question asked a week before is always better than a problem discovered on procedure day. Our guide to the LASIK consultation covers the evaluation that precedes all of this — preparation begins once candidacy is confirmed and a date is set.
Stopping Contact Lenses
The most common pre-operative requirement is also the one patients most often underestimate: you must stop wearing contact lenses for a period before both the final measurements and the procedure. Contact lenses temporarily reshape the cornea, and measurements taken while the cornea is still molded by a lens can be inaccurate — which means the laser treatment plan could be based on wrong numbers.
The required lens-free period varies by lens type and by clinic protocol. Soft lenses generally require a shorter break than rigid or specialty lenses, but the exact duration is set by your provider — confirm it when you book, and take it seriously. Switching to glasses for that period is the standard approach. If you do not currently own up-to-date glasses, arrange them in advance; you will need them during the lens-free weeks and again during early recovery.
Medications, Health, and Eye Conditions
Before the procedure, the clinic reviews your medications and health history — or should, if it has not already done so thoroughly at the consultation. Certain medications and conditions can affect healing or dry eye, and the surgeon needs the complete picture. Bring a current list of everything you take, including over-the-counter products and supplements, and mention any changes since your consultation.
If you manage dry eye, blepharitis, allergies, or other eye conditions, the clinic may prescribe pre-treatment — for example, a course of lubricating drops or lid hygiene — to optimize the eye surface before surgery. Follow these regimens as directed; they are part of the preparation, not optional extras. And if you develop an eye infection, significant illness, or any new eye symptoms in the days before the procedure, contact the clinic promptly rather than hoping it resolves — the date can usually be moved, and proceeding with an unhealthy eye is not worth the risk.
Arranging Logistics: Transport, Time Off, and Help
LASIK is an outpatient procedure, but you will not be driving yourself home. Dilation, the procedure itself, and immediate post-operative blurriness and light sensitivity make driving unsafe, so arrange for someone to take you to and from the clinic. Confirm this plan the day before; it is one of the most common day-of complications when it falls through.
Plan time off realistically. Many people return to desk work within a day or two, but that varies by individual, by procedure type, and by the nature of the work — and our recovery timeline explains why early expectations should stay flexible. If your work involves dust, wind, physical strain, or long screen hours without breaks, discuss the timeline specifically with your surgeon rather than assuming the fastest case applies to you. Having a backup plan for an extra day or two of reduced activity removes pressure to rush healing.
Line up practical help too: someone to handle driving for the first day or two, and a plan for childcare or other responsibilities that cannot wait. Small logistics handled in advance make the first 24 hours — when your eyes need rest and protection most — significantly calmer.
The Day Before
The day before the procedure is for confirmation and simplification. Confirm your arrival time and location, your transportation, and that you have the prescribed drops or supplies if the clinic asked you to obtain them in advance. Avoid alcohol the night before, get normal sleep, and avoid trying new eye products, makeup, or creams that could irritate the eyes.
This is also a good moment to settle any remaining financial questions: confirm the total price, the payment method, and what is included, so there are no surprises at check-in. Our guide to questions about LASIK costs before booking lists what a complete quote should contain. Procedure day should be about the procedure, not about paperwork confusion.
Procedure Day: What to Do and Avoid
On the day itself, the standard guidance is straightforward: do not wear eye makeup, creams, lotions, or perfumes and colognes — particles and fragrances near the surgical field are unwelcome. Wear comfortable clothing, avoid lint-shedding fabrics near the face if you can, and eat normally unless the clinic instructed otherwise. Bring your glasses (not contact lenses), your ID and payment as instructed, and the drops or paperwork the clinic requested.
Arrive at the stated time; clinics run on tight surgical schedules, and lateness can mean rescheduling. Expect the appointment to include final verification measurements, consent paperwork review, the procedure itself, and post-procedure instructions with initial drops. You will leave wearing eye shields or sunglasses, with instructions for the first hours at home: rest, keep the shields on as directed, use drops on schedule, and do not rub your eyes.
Mentally, expect the strange-but-manageable: you will be awake, you will feel pressure and see lights and movement, and the whole laser portion will be over quickly. Patients who know what to expect generally report the experience as less stressful than they feared. If anxiety is significant, mention it to the team — they manage nervous patients every day.
Setting Up for Recovery in Advance
A little preparation at home pays off during the first days of healing. Fill any prescriptions before procedure day if the clinic allows it. Stock preservative-free lubricating drops if recommended. Prepare a comfortable resting spot with the lights dimmable. If you wear eye shields for sleep, practice keeping them on. Arrange your schedule so the first 24 hours are genuinely restful — no "quick errands" that turn into a full day out.
Review the aftercare instructions before you need them. Our aftercare guide covers the typical instructions — drops schedules, activity restrictions, warning signs — so that nothing on procedure day is entirely new. Knowing the plan in advance means you can follow it on autopilot when your eyes are tired and your attention is limited.
Questions to Settle Before Procedure Day
A short checklist of things to have resolved in advance: What is the total all-in price, and what exactly does it include? What is the enhancement policy if the result needs fine-tuning? Which drops will I need, and for how long? When is the first follow-up visit, and how are later ones scheduled? What activity restrictions apply to my specific work and hobbies, and for how long? What symptoms should prompt an immediate call to the clinic? Who do I contact after hours if something seems wrong?
Getting answers in writing — or at least confirmed verbally with notes you take — prevents the most common sources of post-procedure frustration: surprise costs, unclear drop schedules, and uncertainty about what is normal versus what needs a call. A clinic that answers these clearly before the procedure is also signaling how it will communicate afterward.
Frequently Asked Questions
How far in advance should I stop wearing contact lenses?
The required contact-lens-free period varies by lens type and clinic protocol — soft lenses generally require a shorter break than rigid or specialty lenses. Your clinic sets the exact duration when you book, and it applies both before final measurements and before the procedure itself, because lenses temporarily reshape the cornea and can distort the numbers the laser plan is based on. Confirm the specific timeframe for your lens type at booking, switch to glasses for the full period, and do not shorten it on your own — inaccurate measurements are one of the few preventable sources of a poor outcome.
Can I wear makeup on the day of LASIK?
No — clinics universally ask patients to arrive without eye makeup, creams, lotions, or perfumes and colognes on procedure day. Particles from makeup can enter the eye area during the procedure, and fragrances are unwelcome near the surgical field. This restriction typically extends into the early recovery period as well; your clinic will tell you when eye makeup can resume. When in doubt about a specific product, ask the clinic rather than assuming — the rule exists to protect the surgical site, and it is easy to comply with.
Do I need someone to drive me home after LASIK?
Yes. You should arrange for someone to drive you to and from the clinic on procedure day. Dilation, the procedure itself, and immediate post-operative blurriness and light sensitivity make driving unsafe, and clinics expect you to have transportation arranged — some will not proceed without it. Plan for help with driving for the first day or two as well, since vision can fluctuate during early healing. Confirm your transportation plan the day before so it does not become a last-minute problem.
What should I eat or drink before LASIK?
In most cases, you can eat and drink normally before LASIK, since the procedure uses numbing eye drops rather than general anesthesia — but confirm with your clinic, as protocols differ. The more common guidance concerns the night before: avoiding alcohol, getting normal sleep, and not trying new eye products. If your clinic gives specific instructions about food, drink, or medications on procedure day, follow those exactly. When instructions and general advice conflict, the clinic's instructions always win.
What if I get sick or develop an eye problem before my procedure date?
Contact your clinic promptly. Eye infections, significant illness, or new eye symptoms in the days before LASIK are reasons to postpone — proceeding with an unhealthy eye is not worth the risk, and dates can usually be moved. The same applies if you could not complete the contact-lens-free period or the prescribed pre-treatment. Clinics handle rescheduling routinely; a short delay for a healthy eye is always preferable to a compromised procedure. Do not try to push through and hope for the best.
