How long to stay in China — by procedure, not by guess
Itinerary structure at partner refractive centers · Researched July 2026 · Published August 2026
LASIK and SMILE: 3 days. TransPRK: 3–5. EVO ICL: 6–7. Those aren't marketing numbers — each one is set by a specific clinical gate that must open before you fly: the day-one check for laser patients, the bandage-lens plan for TransPRK, and the pressure-and-vault check for ICL. This page walks the day-by-day itinerary behind each number, the washout that starts your trip before you leave home, and the one reroute that can stretch a 3-day plan into a week.
The minimum stay, procedure by procedure
| Procedure | Plan for | What gates your departure |
|---|---|---|
| Femto-LASIK | 3 days | Day-one post-op check — most patients cleared to fly with hourly lubricant drops |
| SMILE | 3 days | Same day-one gate as LASIK; no flap changes the aftercare rules, not the itinerary |
| TransPRK | 3–5 days | The bandage contact lens — you can fly wearing it after the post-op check, but vision is still hazy while the epithelium regrows, so many patients stay until it settles or travel with a companion |
| EVO ICL | 6–7 days | Intraocular pressure and lens-vault checks days after implantation — you fly after the pressure check clears, not before |
Typical itineraries at partner refractive centers, researched July 2026. The surgeon's clearance at the actual check — not this table — is what opens the door; the recovery timeline covers what each check assesses.
The 3-day laser itinerary, hour by honest hour
Day one is the real decision day, and it is why two days don't work. The morning is the full diagnostic workup — tomography, pachymetry, cycloplegic refraction, endothelial imaging, the whole instrument table in the candidacy guide — and surgery is only confirmed, quoted, and scheduled after it. Keeping a night between the workup and the theatre is deliberate: it removes the pressure to proceed that same-day surgery creates, and it gives the cycloplegic drops (which blur near vision for hours) time to wear off. About one inquiry in five ends up matched to a different procedure than the one asked about, and that conversation belongs on day one with an open calendar, not in a pre-op corridor.
Day two is surgery — minutes per eye, most of the day free before and after, with the first hours spent resting behind dark glasses. Day three is the post-op check: vision measured (typically at driving standard for LASIK/SMILE by now), the eye examined, flying cleared or deferred. Laser patients fly out that afternoon or the next morning, with lubricant drops on an hourly schedule against the dry cabin — the timeline page has the full fly/work/gym/pool schedule from there. The from-$2,190 package on the cost page is built on exactly this 3-day shape.
Why ICL takes a week when the surgery takes minutes
Three reasons, all structural. The sizing scans on days one and two are more consequential than laser diagnostics — anterior-chamber geometry decides the lens size, and sizing is the variable behind vault, the number that dominates long-term ICL follow-up. The lens must then be matched from hospital inventory (or, for prescriptions outside stocked range, custom manufactured — which converts the trip into a planned-around-manufacturing schedule agreed in advance). Surgery is often done one eye at a time. And departure waits on the checks that laser patients don't need: intraocular pressure and lens position, measured in the days after implantation. You fly home after the pressure check clears — typically day 5–7 — not before, a rule that exists because the rare pressure rise is a treated-immediately event, and it should happen within reach of the operating team.
Your trip starts before the flight: the washout
The least-known itinerary fact in refractive travel: contact lenses mold the cornea, and molded corneas produce false measurements. Soft lenses come out days before the workup; rigid lenses, weeks before. Arrive still wearing them and day one's scans are measuring your contacts, not your eyes — and an honest center will re-measure after a washout rather than cut to a bad map, which costs exactly the days a 3-day itinerary doesn't have. Build the washout into your calendar at booking time, and send your prescription history and any existing corneal measurements ahead: remote pre-screening catches obvious procedure mismatches before flights are booked, though the binding decision is always made on-site from the hospital's own workup.
The reroute that stretches the calendar
Plan for the possibility that you fly out on a 3-day laser plan and the workup says otherwise. The most common significant reroute — thin corneas or a prescription past the laser range, per the options map — is laser to ICL, which moves you from the 3-day to the 6–7-day schedule, subject to lens availability, with the price changing to ICL's rate before anything is scheduled. This is why flexible return tickets are the standing advice, why the final quote comes after day one, and why a companion's ticket should be flexible too. Crew and pilots: your calendar runs on different, longer rules — the stability window your medical examiner needs has nothing to do with the tourist itinerary; the aviation guide covers it.
Questions people actually ask
How long do I stay for LASIK or SMILE?
Three days: workup, surgery, post-op check — most patients cleared to fly at the day-one check with hourly lubricant drops for the cabin.
Why not two days?
The workup and surgery shouldn't share a day — the workup decides whether and which surgery happens at all, and cycloplegic drops blur vision for hours. The night between is a feature, not padding.
How long for ICL?
Six to seven days: sizing scans, lens matching, often one eye at a time, then the pressure and vault checks that gate departure. Custom-manufactured lenses are scheduled around manufacturing time instead.
What do I do before flying to China?
The contact-lens washout (soft: days; rigid: weeks before the workup) and sending your records ahead for remote pre-screening. Both protect the itinerary you booked.
Can my procedure change after I arrive?
Yes — about one in five inquiries is matched to a different procedure at the workup. A laser-to-ICL reroute stretches the stay to 6–7 days, so book flexible return flights.
