Bladeless Lasik surgery is a corrective eye treatment that utilizes laser technology to treat a variety of refractive issues of the eye. This procedure treats astigmatism, farsightedness, and nearsightedness. Unlike traditional Lasik surgery wherein a blade is used to create a thin flap in the cornea before beaming the eyes with laser, bladeless Lasik involves using a femtosecond laser to create the flap. Just like traditional Lasik, bladeless Lasik is just as safe and effective.
Types of Bladeless Lasik Procedures
All types of bladeless Lasik treatments utilize laser technology to correct vision problems. The treatments could be based on femtosecond laser or excimer laser. Femtosecond laser directs the light energy precisely to create thin, hinged flap in the cornea. The flap is lifted from the eye to allow the laser in.
On the other hand, an excimer laser is applied to the newly exposed eye surface. The tissues are removed in a precise pattern to reshape the cornea.
IntraLase uses femtosecond laser for bladeless Lasik in the US. Since it was introduced in 2001, different types of bladeless Lasik treatments have emerged. However, the technology behind these treatments is still based on femtosecond laser. Today, bladeless IntraLase is now called iLASIK.
This treatment utilizes portable femtosecond laser called Ziemer Femto LDV. The laser can be combined with other approved systems by the company that developed zLasik to create a corneal flap.
This treatment utilizes femtosecond laser to restore 20/10 vision. It can be combined with different excimer laser systems to treat sight problems.
One of the latest treatment used to treat vision problems, VisuMax received its FDA approval in 2007. This procedure can be combined with different laser systems to correct eye problems.
Advantages of Bladeless Lasik Surgery
Reduced Risks and Complications
Traditional Lasik treatment is an effective procedure to correct vision problems. However, the treatment is not perfect. There are instances wherein eye tissues were damaged because a blade was used in traditional procedures.
You don’t have to worry about the same risks with bladeless Lasik. Bladeless does not use a blade to cut a flap in the cornea. All procedures are done using laser tech. The machines that utilize the laser are very precise so potential risks and complications are reduced significantly.
Better Flap Quality
Because the machine that applies the laser is extremely precise, the corneal flap quality is enhanced too. The instrument creates the same flap thickness regardless of the shape of the patient’s cornea. On the other hand, traditional Lasik could cause “buttonholes” in the flap because the blade is not as precise.
Disadvantages of Bladeless Lasik Surgery
Although bladeless Lasik is more advanced than traditional Lasik, the eyes are still vulnerable to common side effects stemming from an eye surgery. One of these side effects includes dry eyes. However, bladeless Lasik surgery results in less severe dry eyes compared to traditional Lasik. The length of the recovery period is also shorter.
Sensitivity to Light
All patients who have undergone laser treatment to correct vision problems will become sensitive to bright lights temporarily. That includes those who underwent bladeless Lasik.
Because the technology is still new, bladeless Lasik costs more than traditional Lasik surgery. But the results you get from this treatment is well worth the extra expense.
