Biometer + Pachymeter GRU-5000 AP

Gilras GRU-5000 A/P is a cost-effective Ultrasonic A-Scan Biometer Pachymeter which eliminates signal loss delivering amazing clear images.
The GRU-5000 A/P combines two indispensible tools into one compact unit. This Gilras unit allows for both A-Scan biometry as well as pachymetry. An essential part of ophthalmic practice, A-scan ultrasound is crucial in the preoperative evaluation of cataract surgery patients. The Gilras GRU-5000 A/P technique takes multiple, accurate readings and offers a wealth of features that will help you deliver better patient care and select an appropriate intraocular lens (IOL) power for cataract patients. Likewise, you can count on the precise corneal pachymetry readings you’ll achieve with the GRU-5000 A/P. Whether you are comanaging LASIK, screening for keratoconus, preparing for LRI surgery, or going the extra mile with your glaucoma patients, this unit is programmed with all the features and data tools you will need. You’ll get all this and more in a portable, sleek design when you choose the GRU-5000 A/P.
