LASIK or PRK If You Play Contact Sports or Have a Physical Job
If you get hit in the face for sport or for work, the choice between LASIK and PRK stops being about convenience. It comes down to one structure — the LASIK flap — and how much risk you want to carry for decades.
For most active people, either procedure works and LASIK’s faster recovery wins. The exception is anyone who takes regular, direct blows to the face: boxers, martial artists, wrestlers, rugby players, police officers, firefighters and military service members. For them PRK is usually the better choice, because a LASIK flap never regains its full original strength and a hard blow can displace it, even years later. PRK has no flap. Final vision is the same; PRK simply takes about a week to recover instead of a day.
Why the flap is the whole question
LASIK and PRK use the same Alcon WaveLight Allegretto excimer laser to reshape the cornea. In LASIK, a second laser (the WaveLight FS200) first creates a very thin flap; the treatment is done underneath and the flap is laid back down. It seals within hours, which is why LASIK patients see well the next day.
What patients are rarely told is that the flap edge heals, but the flap never bonds back with its original strength. In everyday life this does not matter: rubbing your eyes or a toddler's hand to the face will not move a healed flap. A hard, direct blow — a fist, an elbow, a stick — can, and that can happen years after surgery.
Traumatic flap displacement is uncommon, and when seen promptly the flap can usually be repositioned with good vision. But it is an emergency, it means another procedure, and it cannot happen after PRK. PRK treats the surface of the cornea after the thin outer skin (the epithelium) is gently removed; that skin regrows in a few days and leaves nothing that can be knocked loose.
Sorting your activities honestly
The useful question is not "am I active?" but "how often does something hard hit me in the eye?" Most patients fall clearly into one of three groups.
- Regular, direct contact to the face — PRK is usually the recommendation. Boxing, MMA, Brazilian jiu-jitsu and other martial arts, wrestling, rugby, and full-contact training. The same applies to jobs where a blow to the face is a realistic part of the work: police officers, firefighters, corrections officers, and military service members.
- Occasional contact — a conversation, not a rule. Basketball, soccer, lacrosse, ice hockey, water polo, and racquet sports. Many people in this group do well with LASIK, especially recreational players who wear protective eyewear. Others, such as competitive players or those with thin corneas, are better served by PRK. This is where a careful evaluation earns its keep.
- Little or no contact — LASIK is generally fine. Running, cycling, swimming, hiking, skiing, golf, yoga and the gym. Plenty of trail runners on Mount Diablo and cyclists on the Iron Horse Trail have had LASIK without a second thought. For this group the faster LASIK recovery is usually the deciding factor.
Plan for the life you expect over the next twenty years, not just this season. If you are thinking about starting martial arts or applying to a police academy, say so at the evaluation.
Military and law enforcement
If you serve or plan to apply, check your branch's or department's current policy before surgery. Some programs specify which procedures they accept or how long you must wait before training. Bring any written policy to your evaluation.
The trade-off: PRK recovery takes about a week
PRK's safety advantage for active people is real, and so is its cost in downtime. Here is what to expect:
- Days 1–3. The uncomfortable stretch. A bandage contact lens protects the eye while the surface heals. Scratchiness, tearing and light sensitivity are normal and are managed with prescribed drops and oral medication. Vision is blurry but you can get around.
- Days 4–6. The surface has healed and the bandage lens comes out at a follow-up visit. Most people go back to desk work around this point.
- Weeks 2–8. Vision keeps sharpening as the surface smooths. Anti-inflammatory drops taper over several weeks.
LASIK, by comparison, usually means a few hours of mild irritation and functional vision the next morning. For athletes, timing matters more than the week itself: plan PRK for the off-season or between fight camps, not just before a tournament. Some patients have one eye treated at a time; others prefer to recover once.
Getting back to training
Return-to-sport timing is individual and Dr. Feiz will clear you at your follow-up visits, but as a general guide:
- Light cardio (walking, stationary bike) is usually fine within a few days of either procedure, as long as sweat is kept out of the eyes.
- Swimming, hot tubs and lakes wait until the surface is fully healed — usually about two weeks after LASIK and somewhat longer after PRK. Ocean and lake water carry more infection risk than a chlorinated pool.
- Contact sports and sparring wait longer, typically about a month, and always with protective eyewear or headgear where the sport allows it.
After PRK, outdoor athletes should wear UV-blocking sunglasses for the first several months while the cornea remodels.
Laser correction does not make your eyes tougher
Neither procedure protects your eyes from injury. A ball to the eye can still damage the retina or the bones around the eye whatever surgery you have had. PRK removes one specific extra risk — the flap — not the general risk of trauma. If your sport has protective eyewear, keep wearing it.
Other things that can tip the decision
Your corneal measurements can override everything else. Thin corneas, mild irregularities on topography, or dry eye (made worse by wind and sun) all favor PRK regardless of your sport.
Because both procedures are the same price at this practice — $2,650 per eye, all-inclusive, with 12 months of follow-up and any needed enhancements — cost never pushes the recommendation one way or the other. The recommendation is simply the procedure that is safer for your eyes and your life.
What to tell us at your evaluation
The free LASIK evaluation is with Dr. Feiz personally and covers both procedures. Come ready to describe every sport you play (and plan to start), your job, how much downtime you can take and when, and any military or department vision policy that applies to you.

Frequently asked questions
Can a LASIK flap really come loose years later?
It is uncommon, but yes. The flap edge heals, yet the flap never bonds back with its original strength, so a hard direct blow can displace it long after surgery. Prompt treatment usually restores good vision. PRK has no flap, so this cannot happen.
I run and cycle. Do I need PRK?
Usually not. Running, cycling, swimming, hiking, skiing and gym training carry little risk of a direct blow to the eye, and most people in these sports do well with LASIK. Your corneal measurements still have the final say.
Is PRK vision as good as LASIK vision?
Yes. Long-term vision after PRK and LASIK is equivalent. The difference is recovery: about a week of discomfort and blurry vision with PRK, versus about a day with LASIK.
How soon can I go back to sparring or contact sports?
Typically about a month after surgery, once Dr. Feiz has confirmed the eye has healed, and with protective eyewear or headgear wherever the sport allows it. Light cardio is usually fine within a few days.
Does PRK cost more than LASIK?
No. Both are $2,650 per eye, all-inclusive, with a free evaluation and 12 months of follow-up and enhancements, so the recommendation is based only on which procedure is safer for you.
