Gilras ophthalmic ultrasound
Gilras is the ophthalmic-ultrasound line that anchors the diagnostic-imaging program at US Ophthalmic. It covers the three ultrasound workups an eye-care practice relies on most: A-scan biometry for axial length and IOL power planning, corneal pachymetry for central corneal thickness, and B-scan imaging for cross-sectional views of the posterior segment. The appeal for practice and lab owners is a straightforward one. Gilras systems deliver the clinically meaningful measurements ODs and MDs need for cataract and IOL surgery, refractive co-management, and posterior-segment assessment, at a price point that keeps ultrasound within reach of a wider range of clinics.
What sets Gilras apart in our catalog is not just the hardware but everything standing behind it. Every Gilras unit and probe we supply is supported by our in-house technical and repair department, genuine replacement parts and probes such as the B-Probe 10MHz on this page, and a US warranty with real service behind it. That means a Gilras A-scan, pachymeter, or A/B scanner stays in service for years, and when a probe wears or a console needs attention, you are working directly with the team that knows the equipment rather than shipping it overseas.
How to choose your Gilras system
- Which measurements you actually need: Decide whether your priority is A-scan biometry (axial length for IOL power), pachymetry (corneal thickness), B-scan imaging (posterior segment), or a combination. That single decision points you to the right Gilras model.
- Combination vs. single-function: A combination unit like the GRU-7000 (A-scan plus B-scan) or the GRU-5000 A/P (A-scan plus pachymeter) consolidates two workups into one console and footprint, while a dedicated A-scan keeps things simple for a cataract-focused practice.
- Probe frequency and coverage: Gilras systems use a 10MHz A-scan probe for axial length, a 20MHz probe for pachymetry, and a 10MHz B-scan probe for imaging through opaque media. Match the probe set to the exams you perform.
- IOL formula support: For cataract planning, confirm the calculation formulas on board. Gilras biometry units carry the standard set, including SRK-II, SRK-T, Binkhorst-II, Holladay, Hoffer-Q, and Haigis.
- Service, warranty, and spare probes: Probes are consumable over a device's life. Buying into a line backed by our in-house repair department, genuine Gilras spare probes, and a US warranty protects uptime long after the sale.
The Gilras line
The Gilras family scales from a dedicated A-scan biometer up to a full A/B combination console, with replacement probes available to keep an existing unit running. Below are the core Gilras models and where each one fits.
| Model | Type | Best for |
| GRU-7000 | Combination A-scan / B-scan ultrasound console | Practices that need biometry and posterior-segment imaging in one system |
| GRU-5000 A/P | A-scan biometry + pachymeter combination | Cataract/IOL workups plus corneal thickness for refractive and glaucoma care |
| GRU-5000 A | Dedicated A-scan biometer | Axial length measurement and IOL power calculation for cataract planning |
| B-Probe 10MHz | Replacement 10MHz B-scan probe | Restoring or maintaining B-scan imaging on a Gilras A/B scanner |
Frequently asked questions
What does the Gilras ultrasound line measure? Across the family, Gilras systems handle three core ophthalmic ultrasound tasks: A-scan biometry (axial length for IOL power calculation), pachymetry (central corneal thickness), and B-scan imaging (two-dimensional cross-sections of the vitreous, retina, and orbit). The specific model determines which of these a given unit performs.
What is the difference between the GRU-5000 A/P and the GRU-7000? The GRU-5000 A/P pairs A-scan biometry with a pachymeter, so it is built around cataract/IOL planning plus corneal thickness for LASIK co-management and glaucoma care. The GRU-7000 pairs A-scan with B-scan imaging, adding posterior-segment visualization for eyes you also need to image. Choose based on whether pachymetry or B-scan imaging matters more in your practice.
When would I use B-scan imaging instead of an A-scan? B-scan is the tool for evaluating the posterior segment when the media are opaque and you cannot see in directly, such as dense cataract, corneal scarring, or vitreous hemorrhage. A 10MHz B-scan probe like the Gilras B-Probe is well suited to assessing vitreous disorders, posterior vitreous detachment, retinal detachment, and ocular trauma. A-scan, by contrast, is a one-dimensional measurement used mainly for axial length and biometry.
How are Gilras units serviced and supported in the US? Gilras systems are backed by our in-house technical and repair department, genuine replacement parts and probes (including the B-Probe 10MHz), and a US warranty. You work directly with our service team rather than sending equipment abroad, which keeps a Gilras A-scan, pachymeter, or A/B scanner in reliable clinical use over the long term.
