Single-use adjustable trephine

Building on its experience, Moria has introduced a new Single-Use Adjustable Vacuum Trephine.

Designed to produce straight-walled cuts, the adjustable trephine features an adjustment ring enabling setting the blade descent depth. Its centration indicator ensures no parallax errors.

Moreover, its vacuum surface is 3 times more efficient than a standard trephine and its limbal suction features a central cornea support design for a perfect conformation to the cornea.

This trephine can be used on a Moria Single-Use Artificial Chamber to cut the donor cornea from the epithelial side, which allow the reduction of the shape disparity and may induce less astigmatism.

Non-contact tonometer

Corvis ST, a new non-contact tonometer with an ultra-high-speed Scheimpflug camera that can visualize the reaction of the cornea on air impulse, is now available from Oculus.

The company reports that this instrument has the potential to determine a highly accurate value of IOP that is close to the 'true IOP', based on the measured IOP, the biomechanical properties and the corneal thickness.

Additionally, screening for corneal ectasia and visualizing the effect of CXL is possible with the Corvis. The system can monitor changes of the deformation response of the cornea and as such enables the user to distinguish between normal and ectatic corneas, as well as quantifying the effect of CXL.

Continuous IOP monitoring

Patients can wear the IOL for up to 24 hours and can perform every day activities, including sleeping. An adhesive antennae is worn around the eye and is connected to a portable recording device.

The data collected from the device is then transferred to the practitioner's computer for analysis. This complements punctual tonometer readings to offer a qualitative profile of a patient's IOP and thus optimization of glaucoma management.

Internal limiting membrane dye

The non-toxic and biocompatible dye selectively stains the ILM, enabling the clear distinction between underlying retinal tissues and epiretinal membranes.

Brilliant Peel sinks onto the required surface in the liquid-filled eye and does not mix with rising agents. The removal of the ILM is safe, precise and non-traumatic.
