Zyoptix XP Hansatome

Advance VisionCare use the latest in technology for microkeratomes- the Bausch and Lomb Zyoptix XP Microkeratome. Mr Pillai has been using various microkeratome over the years and finds that The XP Hansatome, along with the rest of the technology in the clinic, produces the more accurate and reproducible results with an incredibly low complication rate.

Advance VisionCare has full control over what technology to implement and will only change if it is proven to be an advantage to the patient and the results that can be achieved.

Advantages of the Mechanical Microkeratome

Mechanical microkeratomes have several significant advantages over laser flap-making. With a mechanical microkeratome, LASIK is a one-laser procedure; there's no moving of patient or furniture to get from one laser to the next. The mechanical microkeratome is also faster, so there is less drying of the eye, which can affect the accuracy of the laser procedure. And with a mechanical microkeratome suction is engaged for 10-15 seconds rather than the minute or more required by the laser; less time under suction further reduces the very small risk of a severe vascular event of the retina or optic nerve. In addition, with a mechanical microkeratome, such as the Zyoptix XP, there is no need to do a manual dissection of the flap, which carries a risk of flap tears.

Intralase vs. XP microkeratome

At Advance VisionCare we have decided to use the Zyoptix XP microkeratome over the much publicized 'Intralase' method for creating the corneal flap. Although there is plenty of marketing information to support the manufacturer of the femtosecond laser claims that the adoption of this laser can reduce complications and even increase accuracy of results there is very little peer reviewed studies that substantiate this. In several recent reviews it has been stated that there is little to choose between them and that the XP has benefits over the Intralase TM.

Make sure that the information that is being compared is relevant. There are different types of microkeratomes, the latest and most accurate being the Zyoptix XP.

TTSH Study- October 2005 Comparing flap parameters and clinical outcomes between the Zyoptix XP microkeratome and Intralase FS Device.

CONCLUSION

The TTSH Study is the first controlled prospective, randomized, contralateral eye study to compare flap parameters created by the Zyoptix® XP Microkeratome and the IntraLase Femtosecond Device. Study results demonstrate that the standard deviation in flap thickness achieved with the Zyoptix® XP Microkeratome is equivalent to that achieved with the IntraLase Femtosecond Device. However, what is arguably more significant is that - Zyoptix XP Microkeratome achieved greater accuracy and predictability in creating the desired flap thickness: the 120- micron head produced a mean flap thickness of 116 microns (US) and 109 microns (OCP), while the femtosecond laser programmed to create 120 micron flaps achieved significantly thicker results with a mean thickness of 152 microns (US), 137 microns (OCP). In conclusion, the results of this study demonstrate that the Zyoptix XP Microkeratome provides surgeons with a precise, predictable, and practical tool as they strive for the ideal thin, corneal flap during LASIK.

2nd Study

"The Zyoptix XP microkeratome is a significant upgrade from its predecessor, the Hansatome. Advances include smoother beds, absence of external gears, the ability to vary flap position, left/right selector switch, fully interchangeable parts, a motor sleeve that can be sterilized, and tighter blade tolerances that give new microkeratome flap-thickness reproducibility on a par with laser flap making devices. In terms of what it offers patients and surgeons, I believe that at the present moment a mechanical microkeratome offers a better option than laser as a flap-making technology."
