Dr. Motwani uses two different methods and devices for making the flap. Both make reliable thickness flaps that are consistently checked to ensure safety. The first is the Ziemer Crystalline Femto LDV laser device system for Z-Lasik. This device is unique in that you do not have to go between one device to make the laser flap, and another to do the laser. It allows for the laser flap and laser to be done in one spot. It also uses low energy to make the flap minimizing inflammation and swelling. Dr. Motwani was the first to have the original Ziemer Z-Lasik system in San Diego. The advantage to the femtosecond laser flap making system is that reliable thickness flaps are made. The disadvantage is time (the procedure takes 30-60 seconds to make the flap, and the fact that energy has to be used to make the flap in the cornea which leads to greater swelling and somewhat slower visual recovery.
The second device is the Moria M2 Evolution System. This was the pinnacle of development of the blade microkeratome. A special source of blades that Dr. Motwani helped to develop is used to ensure reliable safe, reliable thickness flaps. Because the system only takes 1.5 seconds to make the flap, the entire procedure is done in under 10 seconds. Because no energy is put into the flap, the healing time is faster, with visual recovery usually starting almost immediately.
At Motwani Lasik Institute we want our patients to be fully informed. Although making reliable thickness flaps is important, how a flap is made makes no difference on the visual correction and how someone will ultimately see. The best laser devices minimize the laser energy to decrease swelling and allow for fast visual rehab. The Ziemer is one of the lowest energy laser flap making devices, so is excellent at this. Unfortunately, one of the most confusing marketing tactics that Lasik centers use is the description of how the flap is made. Somehow this becomes the focus of the Lasik procedure, when in reality how a flap is made has absolutely no impact on the visual outcome of the Lasik procedure. The most important aspect of making a flap is reliable flap thickness, which is important for safety. Otherwise, a flap is a flap is a flap. As long as a device makes a consistent thickness flap, then the safety profile is pretty much the same for all of them. The difference in devices is usually in the time to make the flap, the time your vision is dark, and the amount of energy it takes to make the flap which affects healing time. Once the flap is made using any device, the real work begins in the re-shaping of the cornea.
Feel free to discuss during your consultation the merits of both ways of making the flap, or just let Dr. Motwani recommend which device is right for your particular case.
