dyes, darkening the red structures with respect to the
membranes (white) and other eye tissues.
Air tamponade (only R-Evo Smart CR)
The air- tamponade system uses sophisticated technology
for automatic control of ocular pressure. This allows the
surgeon to introduce sterile air at a pre-set pressure (in
mmHg), while the system automatically balances the
variations due to possible leaks coming from the surgical
incisions.
The air delivery module of the R-Evo Smart CR Medical
Device is designed to provide sterile, low-pressure air
adjustable over the entire 5-120 mmHg range.
An encapsulated disposable membrane filter is mounted to
the external air supply tube, connected to the front panel
air socket, so that virtually all types of particles are
removed when air passes through the filter. An automatic
system, controlled by touch screen or pedal, allows you to
switch from irrigation with BSS to air tamponade and vice
versa, without having to operate any manual tap.
Silicone oil tamponade (only R-Evo Smart CR)
The silicone oil injection device is a unit formed by a
syringe, previously filled with silicone oil, connected by
high pressure tubing to the front panel of the Medical
Device.
The syringe is activated by compressed air which is
controlled linearly by the foot switch.
Phacoemulsification
The piezoelectric handpiece made by OPTIKON 2000 S.p.A.
can be connected to the phaco socket. The handpiece
contains a piezo transducer that oscillates at a frequency of
40 KHz (+4.5 kHz/-1 kHz) with an amplitude of about
100μm. The piezo transducer of the handpiece includes
three different components:
– The PIEZOELECTRICAL CERAMIC ELEMENT that converts
the electrical energy supplied by the control console
directly into mechanical oscillating movements at about
40,000 cycles per second (40 kHz).
– The BODY that amplifies and mechanically transmits the
movement of the ceramic piezoelectric element to the
tip.
