All-laser LASIK uses a femtosecond laser to create the corneal flap that the second laser then reshapes. Blade LASIK, the older technology, uses a small oscillating blade called a microkeratome to make that flap. The result on paper looks similar. The precision, predictability, and dry-eye profile underneath are different enough that almost every serious LASIK practice in Plano and Dallas-Fort Worth has moved to all-laser.
What’s a corneal flap and why does it matter?
LASIK works in two parts. First, you create a thin flap on the surface of the cornea. Second, you lift that flap and use the excimer laser to reshape the tissue underneath. The flap goes back down and the eye heals around it.
The first step is where all-laser and blade LASIK part ways. Everything else is the same.
How does the all-laser flap work?
The femtosecond laser creates the flap by firing thousands of microscopic pulses at a programmed depth and shape. The result is a flap with a uniform thickness, a precise diameter, and clean edges. Most surgeons in Plano can program it within 5 to 10 microns of accuracy.
That precision matters because the cornea is roughly 500 microns thick to begin with. Working in that thin a layer, the difference between a smooth flap and an irregular one shows up in your visual quality afterward.
How does the blade version work?
The microkeratome is a small mechanical device that slides across the cornea and shaves off a flap. It’s still a careful instrument, but the accuracy depends on factors the surgeon doesn’t fully control. Things like blade quality, suction pressure, and the speed of the pass.
In the right hands, blade LASIK still produces good outcomes. In the same hands with all-laser, the outcomes get tighter. The thickness varies less. The edges seal cleaner. The flap rotates back into the exact place it came from with better registration.
Which one has fewer dry eye problems?
This is where the conversation usually lands for patients in Dallas-Fort Worth. Dry eye after LASIK is the most-talked-about side effect, and the data suggests all-laser LASIK has a slightly milder, shorter dry eye profile.
The reason is partly about how the corneal nerves are cut. With all-laser, the flap depth and architecture can be customized to spare more of those nerves. With a blade, you take whatever depth and angle the device gives you.
For patients in North Texas, where the climate is dry to begin with, the dry eye conversation is real. Allergies, ceiling fans, screens, and Texas wind all conspire against your tear film. A LASIK technique that preserves more corneal sensation is worth a few hundred dollars.
Why do most Plano clinics still call it LASIK if there are two versions?
Because the patient outcome category is the same. Both are LASIK. The flap, the laser reshaping, the next-day vision. Marketing teams don’t usually distinguish them at the headline. The difference shows up in the consultation, the consent form, and the equipment in the room.
If you want to know which version a clinic is offering, ask directly. Is the flap made with a blade or with a femtosecond laser? A straightforward question that should get a straightforward answer.
Does all-laser LASIK cost more?
Slightly, yes. The femtosecond platform costs the practice more to maintain, and the per-eye disposables are pricier. In Plano in 2026, the difference between blade and all-laser LASIK at most clinics is in the $300 to $700 per eye range. You can see our full pricing page for context.
At Visionary Eye Surgery, we don’t offer blade LASIK. The precision difference matters too much for the cost gap to be worth it, in my judgment. Different surgeons may disagree, and that’s fine.
Is blade LASIK unsafe?
No. Properly done, it’s safe and effective. Millions of patients have great vision after blade LASIK. The point isn’t that one is dangerous and the other isn’t. The point is that one is more predictable, and predictability is what you want when someone is operating on your eyes.
Who should still consider blade LASIK?
Probably nobody, if all-laser is available and affordable for them. The reason blade LASIK still exists in some clinics is mostly equipment investment. A blade microkeratome costs a fraction of what a femtosecond laser does.
For patients with very specific corneal anatomies, sometimes a particular flap geometry is preferred and an experienced surgeon will choose their tool accordingly. But for the typical Plano LASIK candidate in 2026, all-laser is the default for a reason.
What if I’m not a LASIK candidate at all?
Some patients in DFW are better served by SMILE eye surgery or EVO ICL. The consultation tells us which one. If you want to know which version makes sense for your prescription, book a consultation and we’ll walk through it.
