VisuMax 800 device (Carl Zeiss Meditec)
VisuMax 800 device is the latest generation of femtosecond laser from Carl Zeiss Meditec (Germany) and has been introduced as a successor to the successful VisuMax 500 model. The main focus of this device is corneal refractive error correction surgeries, especially SMILE Pro (an advanced version of SMILE) and femtolysis.
🔍 Live OCT status in VisuMax 800
Unlike some femtoscan devices that are mainly designed for cataract surgery (such as LenSx or LensAR), the VisuMax series, including the 800 model, typically does not have an internal live OCT system during corneal surgery. It is not. Reasons and alternative features: 1. Focusing on the speed and accuracy of the cornea: VisuMax 800 has dramatically reduced the cutting time (Flap or Lenticule) by increasing the laser pulse frequency from 500 kHz (in the 500 model) to 2 MHz (2000 kHz). seconds.
• Advantage: this high speed greatly reduces the stress of the patient and the surgeon and reduces the risk of eye movement or loss of suction.
2. Digital Assistant Systems: Instead of OCT, this device uses other advanced systems to increase accuracy: • CentraLign®: Centering Aid that helps to accurately position the eye. • OcuLign®: Cyclotorsion Adjustment to correct rotational astigmatisms. Surgery.
3. Main use in cornea: VisuMax 800 is specially designed for corneal surgeries (SMILE Pro and Femtolysic), while Live OCT is a key feature in devices that perform femtosecond laser cataract surgery (FLACS) (like LenSx, Victus) to make more precise capsular and lens nucleus incisions.
Conclusion:
VisuMax The 800 Live lacks intraoperative OCT, but it makes up for it with ultra-high speed, reduced treatment time, and precise digital guidance systems for centering and correcting eye rotation (which are critical for corneal refractive surgeries).
