The LEXACOR Philosophy

Our initial idea is to design a laser which is versatile, offering many treatment options.

Mobile for use in different operating rooms within the clinic. Upgradable and compatible to already existing Excimer Laser Systems or surgery tables.

Treatment Options

The LEXACOR Laser is open to a large number of applications. The basic configuration includes Lasik Flaps, Corneal Pockets and Tunnels. Optionally it can be extended for refractive lenticule extraction and cataract surgery. More applications will be added.

INTUITIVE

All major functions can be controlled by the large touchscreen. The software is designed in an intuitive and straightforward way, leading the surgeon through the procedure. The automated centering feature with a single piece patient interface makes docking simple and safe.

MOBILE

The LEXACOR is stable, compact and mobile. It can be repositioned on the hospital floor, when not needed.

VERSATILITY

When designing the LEXACOR we ensured compatibility to most existing Excimer Laser systems. The laser can easily be moved and positioned near by to the patient bed.

Treatment Methods with the LEXACOR

Femto Assisted Lasik.

LEXACOR 1

The LEXACOR uses a predefined flap program. Hinge positions can be selected to the four main directions nasal, temporal, inferior and superior. Standard settings can be defined for each user. A separate sub menue allows more complex settings such as individual energy settings, spot spacing oblique, angle hinges and much more.

Intrastromal Pockets.

LEXACOR 2

The high repetition rate and optimized spot spacing allows for true corneal cuts with no tissue bridges. This is a requirement for creating an intrastromal pocket. Pocket size, depth and incision width can be selected. A sub menu allows for more specialized settings such as spot spacing, energy and incision direction.

Corneal Tunnels.

LEXACOR 3

Corneal tunnels can be created according to the implant manufacturer’s specifications. Tunnel depth, inner radius, width and opening position, can be selected in the main menu. In the sub menu spot spacing, energy and more can be selected.

Laser Refractive Procedures.

LEXACOR 4

The LEXACOR can be upgraded to perform refractive lens extraction. Parameters such as optical zone, refraction, and openings can be set in the main menue. The sub menue allows entering custom parameters such as energy settings, spot spacing, layer depth and more.

Cataract.

LEXACOR 5

We are supporting an open platform strategy. The LEXACOR is already designed to be upgraded for Femtosecond Laser Assisted Cataract Surgery. This will include capsulotomy (CCC), lens fragmentation, the cut of implant and paracenthesis incisions.

The HexaScanTM Principle

The EXCELSIUS LEXACOR is using a unique scanning pattern creating high resolution cuts.

The treatment area is divided into smaller hexagonal segments. This allows to do real cuts with no tissue bridges, excellent surface quality and large effective optical zones.

The proprietary LEXACOR operating software is using a self learning algorithm determining the size and number of hexagons used for an optimum balance of speed and resolution for each treatment.

We believe this gives us the best possible optical quality with a minimum of optical disturbances due to grating or scattering effects caused by residual line patterns and irregularities.

LASIK Flaps

LEXACOR 6

Hexagon sizes adjusted automatically for best speed and cut quality.
1. Flap rim, downcut can be customized
2. Hexagon sizes are optimized according to flap diameter

Corneal Pockets

LEXACOR 7

For corneal pockets the hexagon spacing is optimized for speed and optimum cut quality to minimize optical distortions when inserting a lenticle implant.

Corneal Tunnel

LEXACOR 8

For corneal tunnels to ensure easy opening, tunnel width and depth as well as access cuts can be customized.

Patient Comfort and Surgeon Control

The LEXACOR is designed for the best patient comfort. Similar to the MICRON M7 Excimer Laser, the delivery arm is moved aside for surgery preparation.The surgeon has full access and free microscope view to the patient eye for draping, applying topical anesthetics and general procedures.

Then the delivery arm is positioned over the eye to be treated. After docking the cut is performed.

During the cutting process the surgeon can observe the whole procedure via the integrated video system. After cutting the applicator arm is moved aside, and the treatment can be continued either by Excimer Laser for LASIK or using the operating microscope for other treatment types.

The LEXACOR uses a single piece patient interface. Optical interface and suction ring are made in one part. This makes the surgery setup quick and easy. Once centered and touching the eye, suction is applied to complete the docking procedure and fixate the eye.

Cost Efficiency

When designing the LEXACOR system intensive attention was paid to easy serviceability and a straightforward modular structure.

This results in great stability and a small number of necessary spare parts. Only application interfaces which are intended for bilateral use are needed as acccessoires.

Footprint

The LEXACOR is designed as one compact unit. The weight of only 230 kg for the whole unit makes it easy to handle.

Moving the laser away when not needed is easy. Also it can be moved towards a patient bed of an Excimer Laser or ophthalmic surgery table for various procedures.

The width of only 750 mm allows passage through the most standard doors.

The robotic delivery arm can be retracted when not in use. For surgery access it can be extended by 350 mm reaching both patient eyes easily.
