Z-LASIK and iLASIK laser eye surgery explained

OK. lots of new laser eye surgery names that appear, so we will confirm what they mean!

Z-LASIK: the blade-free LASIK using the new Swiss Ziemer laser to make a corneal flap, rather than a traditional leaf.

iLASIK: LASIK sheet free, but using the IntraLase laser of americas to make a corneal flap.

Therefore, simple so far. Z for Ziemer laser and i for the IntraLase laser. Both of these devices allow the removal of a sheet to make a physical cut in the cornea. Instead, use precise million laser pulses to create a flap very precise, eliminating the potential risks associated with a metal blade-mechanical system.

So what’s the difference between Ziemer and IntraLase laser?

Ziemer The laser is a new system, with the greatest possible progress of americas flap IntraLase laser manufacturer. Ziemer laser, called the LDV, appears occasionally to eliminate the complications arising with iLASIK. Some iLASIK patients (about 7%), obtaining a sharp discomfort and aversion to light for several days after laser vision correction, known as “transitional sensitivity to light.”

This side effect is not seen with Z-LASIK, possibly due to a much more heavily focused energy laser pulse and greatly reduced the energy per pulse, compared with IntraLase’s flexible approach and greater dispersal of energy through of the cornea.

Studies are under way to compare the two systems in greater detail.

Background on the LASIK procedure:

To create the corneal flap is the first phase of a LASIK procedure. The treatment to correct his view is actually the fact that the corneal tissue below the surface and access to it is made using a surface flap and folds again (very easy).

This flap creation is crucial to the success of the outcome of their LASIK surgery – has to be exactly the right thickness and exactly in the right place. When surgery is complete, it is easy to retreat into position and acts as a delicate venda in the eyes treated. It heals itself.

The microkeratome devices used in LASIK surgery are traditional hand tools with a steel blade ranging, moving back and forth at very high speeds. When using expert who is a good flap, but the thickness can vary over flaps and laser may be more irregular, tend to be thinner in the center.

LASIK complications are very rare. Fact. But when they occur, usually arise from a bad corneal flap created. The use of new lasers femtosecond (Ziemer or IntraLase) greatly reduces the likelihood that any of these complications.
