OUR EQUIPMENT

- Since June 2006, we have been using the new-generation Ferntosecond Intralase FS3 laser for making corneal flaps. It has been used without any complications on over 1,000 eyes.

- For treating sight defects, we have been using the Zeiss MEL 80 excimer laser since October 2004. This laser can be guided taking account of your specific optical aberrations or by corneal topography (topolink). It also possesses iris recognition, an essential asset for treating pronounced astigmatisms. It also has an Eye Tracker capable of reacting in 6 milliseconds, which guarantees that treatment is dispensed perfectly even when eyes move. This is an important safety aspect.

LASER OPERATING THEATRE TECHNICAL CHARACTERISTICS

For optimising operating conditions for the 2 lasers in the theatre and for guaranteeing that the air’s biological quality is perfect both for patients and surgeons, the Roosevelt Vision Laser Centre has decided to refurbish the laser room to create a clean zone with preset air conditions.

The zone has a surface of about 23 m² for the laser room plus an entry air-lock with a section dedicated to cleaning and sterilizing.

The airlock is fitted with a washbasin and a wardrobe so that patients and operators may put on appropriate clothing for use in the operating theatre.

The complete unit is made in perfectly smooth, cleanable clean-room panels with rounded angles. Doors are fitted with cell-controlled detection mechanisms for opening them automatically and avoid any contact between the operator and the doors.

Air-conditioning characteristics of the clean room:

• Temperature level set at 21°C +/-1°C
• Hygrometry level set at 50% +/-5%

Dust-accumulation and microbiological characteristics of the laser room:

• Zone over-pressurised (20 to 30 Pa) compared to the outside with over-pressurised air brought in from roof level and guided to the suction point of the air-conditioning unit for filtration.
• Air flow: 2 400 m3/h or an air circulation rate of 43.5 volumes per hour.
• Filtration with absolute final filters, efficiency ratio H14
• Dust accumulation class: ISO 7 (formerly class 10 000). Idem for the airlock and the sterilization zone
• Microbiological class: Class C
• Laminar flow of a surface of 1.2 m² above the lasers and the patient’s head. Laminar air-flow at 0.45 m/s. Dust accumulation class in this zone: ISO 5 (formerly class 100).Microbiological class: Class A.
