New Device Combines Various Ophthalmology Equipment into Single Instrument

Newly developed device can provide different sights of the eye with an image quality better than using multiple instruments.

Researchers at Nicolaus Copernicus University, Poland and Universidad de Murcia, Spain have developed a device that can provide different views of the eye. Patients receiving eye exams have to go from one imaging device to another in order to properly assess their vision. Additionally, costs associated with maintaining and housing multiple pieces of equipment is high out of which only one is used at one time in a typical ophthalmology center.

Conventional technology images the eye about 3 millimeters in depth. Changing the focus to resolve the front and back of the eye is difficult with conventional optics. The new OCT device is capable to examine the thin layers where the vitreous gel connects with the retina and lens. This can help identify the reasons why the retina often detaches in elderly people.

In order to quickly switch between very different optical properties, the researchers developed an electrically tunable lens into a custom-made optical coherence tomography (OCT) system and used a laser that can rapidly switch between different wavelengths. “We also want to use our instrument to measure opacities in the eye’s crystal lens and the vitreous to better understand how various parts of the eye affect the deterioration of vision,” said Ireneusz Grulkowski of Nicolaus Copernicus University.

According to Medical Devices published by Coherent Market Insights, The convergence of information technology with medical devices is transforming the landscape of patient care. These optics provide a greater range of possible focus while the swept light source laser gives better resolution and faster scanning. “We believe that the ability to measure these opacities and other properties of the eye that couldn’t be examined before will open up many new ophthalmology applications for OCT,” said Ireneusz Grulkowski.
