Facilities
The group has a well-equipped biomechanics laboratory with a number of state-of-the-art instruments, some of which have been developed in house.
The laboratory is essential for our activities as this is where we carry out tests to determine the material properties of tissue and assess the operation of our medical devices. The following list is not exhaustive but includes our most important instruments.
Inflation rig
Costume built inflation test rig for obtaining biomechanics of intact eye globes.
Intraocular pressure monitoring contact lens
The novel contact lens device is able to continuously measure fluid pressure in the eye.

Thickness measurement device (TMD)
Built in-house device capable of measuring thickness of the eye at various locations.
Dual column universal testing system
For application of uniaxial loading on materials to obtain quick insights their behavior.
Slit lamp
a lamp which emits a narrow but intense beam of light, used for examining the interior of the eye.
Pulsair intellipuff
A small, space-saving footprint combined with the elegant, pump, solenoid control valves, a plenum chamber, and an optical mainframe allow efficient and fast pressure measurement.
Corvis Tonometer
Records the reaction of the cornea to a defined air pulse with a newly developed high-speed Scheimpflug-camera that takes over 4 300 images per second. IOP and corneal thickness can be measured with great precision on the basis of the Scheimpflug images.
Pulsair desktop
The Keeler Pulsair Desktop uses advanced optical and sensor technology for positional detection and puff control.
Goldmann Applanation Tonometer
Tonometer is an instrument that is based on Imbert-Fick law. It is considered to be the gold standard instrument for measurement of Intraocular pressure.
Flourescence microscope
A fluorescence microscope is an optical microscope that uses fluorescence and phosphorescence instead of, or in addition to, scattering, reflection, and attenuation or absorption, to study the properties of organic or inorganic substances.
Linkam mini tensile-rig
Designed specifically to characterise samples under controllable tensile force and varying temperatures. Temperature range -196 to 350°C.
Bruker multimode 8 atomic force microscope (AFM)
Atomic force microscopy is a very-high-resolution type of scanning probe microscopy, with demonstrated resolution on the order of fractions of a nanometer, more than 1000 times better than the optical diffraction limit.
Nanoindenter with standard XP indenter and dynamic contact module II (DCM II) heads
Measures Young’s modulus and hardness, including measurement of deformation over six orders of magnitude, from nanometers to millimeters. The system can also measure the complex modulus of polymers, gels and biological tissue as well as the creep response (strain rate sensitivity) of thin metallic films.
Forma upright ultra-low temperature freezer
-80°C lab freezers, also known as ultra-low freezers (ULT), are available first and foremost to protect samples.
Sparkfree 447l chest freezer
Large -20 freezer is available to store samples. It is equiped with advanced monitoring system to ensure of the tempreture and condition of specimens at all times.
