All you ever wanted to know about LASIK

Blade free LASIK: The Next Generation LASIK

Have you been thinking of laser vision correction? Shed your doubts, concerns, specs and contact lenses too, because blade free LASIK has arrived. With blade free LASIK, laser vision correction procedure has become 100 percent blade free and safer.

NASA recommends blade free LASIK to aspiring astronauts to get rid of their specs, as it can withstand high gravitational forces and has been found to be stable and secure even in extreme environmental conditions.

Blade free LASIK versus Standard LASIK

In any LASIK procedure the first step is to create a corneal flap. In standard LASIK the surgeon uses a hand-held oscillating blade called microkeratome to cut the corneal flap. The flap is then folded back and the Excimer laser treats the cornea to correct the refractive error.

In blade free LASIK, femtosecond laser has replaced the steel blade for creation of the corneal flap which improves visual outcome and post-operative comfort for the patient. 

When you opt for advanced blade free LASIK procedure you get a completely integrated, personalized vision correction procedure based on cutting edge technology at every step.

STEP 1

Creating Your Personal Vision Profile

The blade free LASIK procedure is customized for the patient. The first step in blade free LASIK procedure is to perform a series of tests to determine the individual characteristics of your vision, including the WaveScan technology. The WaveScan system creates a 3 – D map of the unique imperfections of your eyes. Then the advanced CustomVue process uses the digital information from that map to design a customized treatment for each of your eyes. The procedure is customized to your personal vision profile.

STEP 2

Flap creation in blade free LASIK

Conventional LASIK uses a machanical instrument with a steel blade called microkeratome to create the corneal flap. Blade free LASIK  procedure uses two lasers instead of just one. The first, ultra fast laser creates a thin corneal flap which is then folded back to allow the second laser to correct your vision based on exact specification/ measurement of your eye(s). The corneal flap created through the laser is many times more accurate than a blade. 

STEP 3

Laser Vision Correction

Once the corneal flap is created, the cornea is treated to correct the refractive error with Excimer laser. This laser has earned FDA approval to treat the broadest range of vision imperfections possible, including mild-to-severe nearsightedness, farsightedness and all types of astigmatism. 

Why is blade free LASIK better?

1. Precise corneal flap results in improved visual outcome

In a standard LASIK procedure, a microkeratome makes a single, one-dimensional cut across the cornea. As it cuts, the blade oscillates back  and forth, which can leave an irregular surface after the flap is lifted.

In contrast to it, femtosecond laser used in blade free LASIK gives a precise, perfect corneal flap. 

2. Safer than standard LASIK

The precise and perfect corneal flap created by the femtosecond laser is more secure & can withstand even extreme environmental conditions.  even NASA has approved it for its astronauts.

3. Treats patients with high refractive errors and thin corneas too.

A thinner and more accurate corneal flap allows patients with thinner corneas or those with higher corrections to qualify as candidates for laser vision correction with blade free LASIK.

Who is a candidate?

The fact is that majority of people who meet the age and general health requirements are good candidates for blade free LASIK procedure.

The basic criteria are :

• You should be 18 years old.
• You should be in good general health.
• You should have a stable vision prescription for at least six months.
• You should have no existing eye disease.
• You should not be pregnant or nursing.
• You should have cornea of adequate thickness.
