OS3/NovitreX®: perfection
in 23G ppV surgery
3000 efficient cuts per minute with the Oertli
23G Twinac stripper, availability of flow controlled peristaltic
or vacuum controlled venturi aspiration at any time during
surgery, best contrast vision with two independent metal halide
illumination sources and the Oertli PMS pars plana Microincision
system make 23G vitrectomy easy and stress free. Now Oertli
has made a further step forwards: Autoseal® PMS
eliminates the need for plugs, keeps the pilot tubes almost
perfectly tight, maintains the IOP constant throughout surgery
and allows free rotation of the infusion terminal. Read more
in Application
Note 2/2008. The Autoseal® PMS components
are available as single use sterile items (VV123110) or in
a complete vitrectomy machine pack with cassette, cutter,
illuminator, air line, stop cock (VV630013A) in boxes of 10.

OS3 opens the path to
1.6 mm coaxial phaco
The OS3 machine now opens access to the most
advanced MICS technology. The CO-MICS 2 system
offers efficiency and phaco times as short as with conventional
2.8 mm phaco, but with improved fluidics performance: nearly
perfect chamber stability and elimination of post occlusion
breaks, excellent holding force and followability. The physical
background of this convincing new concept is described in
Oertli
Application Note 1/2008. No new surgical technique is
required to do CO-MICS 2 coaxial phaco with
1.6 mm incisions (1.4mm to 1.8mm range possible). The OS3
needs no modification or special software. Just change the
blade and set aspiration vacuum 150 mmHg higher than with
your preferred current technique. The CO-MICS 2 components
are available as single use sterile items (VV800833) or in
a complete machine pack with cassette (VV630111C)in boxes
of 10.

OS3/NovitreX® now
with “Good Light” dual light source
The vitreoretinal extension unit NovitreX now
comprises two parallel metal halide light sources. The term
“Good Light” is justified. It is a good
light in every aspect: bright illumination, excellent contrast
viewing and visibility of fine structures but optimum prevention
of toxicity thanks to carefully selected spectrum and energy
levels. Two independent light sources bring best security
in case of lamp failure and allow two light instruments to
be used in parallel. The NovitreX module VC830201 also includes
air and silicon infusion/aspiration.

NovitreX3000® high
speed vitrectomy increases efficiency
The OS3 now drives the Oertli Twinac strippers
with cutting rates up to 3000 cuts per minute. Investigators
were surprised about the true efficiency and usefulness of
this feature. The Twinac/OS3 concept uses compressed air for
both, the cutting and the aspiration cycle of the guillotine
cutter thereby providing perfect control of both processes.
The result is efficient but tension free vitreous removal
with reduction of overall vitrectomy times. In particular
23G surgeries now show vitreous removal times in par with
20G surgery.

Parsplana Micro incision
System PMS opens path to the future
The advantages of the new 23G and 25G technology
over the conventional 20G technology are clear. With an advanced
concept, Oertli has moved beyond the initial difficulties
associated with miniaturization. The future of vitrectomy
is now in your hands!
The Oertli PMS follows the tradition of the
pilot tube concept developed by Professor Klöti in 1973.
In contrast to trocar systems, the transconjunctival incision
is not made via radial puncturing with a polished cannula
and attached tube. The Oertli PMS involves the use of a precisely
tuned MVR blade. This blade permits perfect incisions and
rapid healing. The incision is executed as a tunnel incision
with a flat angle. Self-sealing is consistently excellent.
The exact position of the incision is determined
using a template, with a repositioning of the conjunctiva
in relation to the sclera being achieved simultaneously. The
template is removed only after the pilot tubes have been placed.
The single-piece pilot tubes in the Oertli PMS
system are precision manufactured of solid titanium. This
is why they slide ideally through the incision and remain
in place. In contrast to synthetic tubes, they cannot be damaged
during placement and when changing instruments. They also
offer optimal properties for instrument insertion.
A step-by-step illustrated description of PMS use is contained
in the Application
Note 6, “Microincision in Vitrectomy”.

20G Phaco pack for 2.2mm
incisions
OS3 phaco packs are now available with the 20G
micro tip system. The micro tip allows 2.2mm incisions and
provides excellent followability. The packs include the venture/peristaltic
Twinvac cassette with giving set plus the 20G Excellerator
SU tip (30°) with infusion sleeve and test chamber.
