Reliable ultrasound precision for confident cataract outcomes.
The NIDEK US-1800 is an ultrasound A-scan biometer designed for accurate axial length measurement and IOL power calculation. It is widely used in cataract surgery planning and provides reliable performance, especially in dense cataract cases where optical devices may not work.
The NIDEK US-1800 is a compact and dependable ultrasound biometry system developed for ophthalmic diagnostics. It uses A-scan ultrasound technology to measure the axial length of the eye, which is the most important parameter for calculating intraocular lens (IOL) power before cataract surgery.
As an ultrasound-based device, the US-1800 works effectively even in mature or dense cataracts. This makes it a reliable choice for clinics that require consistent results in all patient conditions.
The system offers both contact and immersion measurement modes, providing flexibility depending on clinical preference. It features a clear waveform display that helps clinicians confirm accurate readings. Built-in IOL calculation formulas support efficient surgical planning.
The NIDEK US-1800 is suitable for hospitals, eye clinics, and outreach programs due to its compact design and easy operation.
Key Features
The NIDEK US-1800 is used for:
It supports accurate surgical decisions and better visual results.
1. What is the NIDEK US-1800 used for?
It is used to measure axial length and calculate IOL power before cataract surgery.
2. What technology does it use?
It uses ultrasound A-scan technology.
3. Can it measure dense cataracts?
Yes. Ultrasound works well in dense and mature cataracts.
4. Does it include IOL calculation formulas?
Yes. It has built-in formulas for IOL power calculation.
5. What is the difference between contact and immersion mode?
Contact touches the eye directly, while immersion uses fluid for more precise measurement.
6. Is it portable?
Yes. The device is compact and suitable for different clinical setups.
7. Is the test painful?
It may cause mild discomfort due to contact, but it is generally well tolerated.
8. Who can operate the device?
