Text B. 9.2 Fundus observation and gonioscopy with the slit lamp
9.2.1 Read and translate text B in written form:
Fundus (eye) observation is known by the ophthalmic and the use of fundus
cameras. With the slit lamp, however, direct observation of the fundus is impossible due to
the refractive power of the ocular media. In other words: the far point of the eye (punctum
remotum) is so distant in front of (myopia) or behind (hyperopia) that the microscope
cannot be focused. The use of auxiliary optics - generally as a lens – makes it possible
however to bring the far point within the focusing range of the microscope. For this
various auxiliary lenses are in use that range in optical properties and practical application.

Text C. 9.3 Portable, clip-on, SLT laser
9.3.1 Read and translate text C:
The Lumenis Selecta II SLT laser offers you all the advantages of a premium SLT
product together with true portability and maximum space utilization. The Selecta II is a
clip-on product; conveniently fitting onto most commercially available converging-optics
style slit lamps. The unique design of the unit’s laser-head makes it especially easy to
attach and disconnect the system – allowing you to use your slit lamp as either a diagnostic
tool, advanced laser delivery device or both.
The Selecta II is compatible with your preferred Slit Lamp, allowing you to
diagnose and treat with your unit of choice.
Optimal Visualization
The Selecta II is compatible with most commercially available converging-optics
style slit lamps, capitalizing on their enhanced visualization capabilities of the anterior
segment.
72
True Portability Weighing only 25 lbs. (11.5 Kg),
the Selecta II can be easily transported from one
location to another, maximizing your investment.
Space Saving The Selecta II is a clip on laser,
compatible with most commercially available
converging-optics style slit lamps. Easily connect it
to your existing diagnostic slit lamp to perform SLT
and stow away at the end the procedure or scheduled
laser sessions.

Lumenis SLT
Selective Laser Trabeculoplasty (SLT) technology was developed and brought to
market by Lumenis, based on the work of Dr. Mark Latina, MD, et.al.
Today, Lumenis prides itself as the company with the most robust clinical data on
SLT, the largest global installed-base of SLT products, the widest range of added-value
products and services to maximize SLT potential in your practice – including robust
patient education collateral and multimedia - and much more!
When you buy an SLT product from Lumenis, you gain immediate access to the
largest network of SLT users worldwide, receive product upgrades and updates, advancenotice invitations to SLT symposia and workshops all around the world and a long list of
other benefits which are exclusive to Lumenis SLT customers.
Furthermore, all Lumenis SLT products were designed to meet the clinically
recommended SLT treatment protocol that we have helped to shape. Buying a Lumenis
SLT product guarantees your ability to customize treatment on a case-by-case basis and
meet SLT treatment protocol requirements.
The Clinical Advantages of Lumenis SLT
Selective Laser Trabeculoplasty (SLT) is a clinically proven laser treatment to
reduce IOP without coagulating the Trabecular Meshwork. SLT represents an evolution
over previous laser therapies as it can be safely repeated if needed.

Lumenis SLT technology uses a Q-switched, frequency-doubled Nd:YAG; 532 nm
wavelength green laser. When applied to the target tissue, the laser is selectively absorbed
by melanin-containing pigmented cells in the Trabecular Meshwork, without causing
thermal or coagulative collateral damage to adjacent tissue. The increase in expression of
biological cytokines and cellular mediator activities following laser irradiation recruit
macrophages to the Trabecular Meshwork. In turn, macrophages remove obstructive
proteins and remodel the Trabecular Meshwork, improving aqueous humor outflow and,
thereby, reducing intraocular pressure (IOP).

10 Unit 10. Phaco Module
Text A. 10.1 Phaco module assembling
10.1.1 Read and translate text A:
Quick-Start Instruction
This section includes complete instructions how to assemble the phaco handpiece
and attach the tubing set of the cartridge. Connect the test chamber on the phaco handpiece
to check the I/A balance.
Figure 22 – Handpiece assembling (position 1)
Figure 23 – Handpiece assembling (position 2)
Connect the infusion bottle to the "giving set" of cartridge. Select Anterior
Peristaltic or Venturi. Depress the priming button and wait till priming is finished. Phaco
Module appears automatically. Set the preset values or select a programmed memory.
Compress the test chamber, depress switch #9, and check if the test chamber shows
78
appropriate pressure at patient eye level. Disconnect the test chamber.
Figure 24 – Handpiece assembling (position 3)
Use switch #9 (position 3) to control the phaco function. The module can provide
linear control of aspiration in combination with both linear, fixed and/or pulsed outputs to
a phaco handpiece. This module features continuous auto-tuning. This allows the
instrument to maintain constant performance and adjust automatically for changes in
loading. When the Phaco is activated, the Irrigation/Aspiration Module is also activated.
The peristaltic pump can produce a maximum vacuum of 400 mmHg and max. 50cc/min
flow independently from each other. The Venturi pump can produce a maximum vacuum
of 400 mmHg. The upper limit can be selected using the preset control buttons. The actual
vacuum level can be controlled up to the maximum, using the Footswitch.
High Vacuum Sensor Cartridge
The ASSOCIATE® operates on one cartridge suitable for Peristaltic and Venturi
aspiration system and is suitable for both anterior and posterior segment surgery. An
integrated microprocessor guarantees an optimal intraocular vacuum and High Vacuum
Occlusion Technology for advanced capsular protection in phaco surgery. Due to the
integrated microprocessor technology, a maximum sterile barrier is guaranteed.
