Based on device, the market is classified into slit lamp, biometer, perimeter, tonometer, optical coherence tomography (oct) scanner, fundus camera, autorefractor & keratometer, and other devices.
Noncontact biometers can provide some anterior segment measurements using the low-coherence reflectometry method.
More recently the Aladdin biometer (Topcon, Tokyo, Japan) has become available for practitioners to use in a clinical setting.
Various biometric parameters such as axial length, anterior chamber depth (ACD), and lens thickness were measured by Nidek echo scan US 800 A--scan biometer for both distant and near focus.
A-scan ultrasonography by (Quantel Medical biometer) was done to measure ACD (anterior chamber depth).
Lensar is working to integrate additional topographers, including the Aladdin Biometer.
TOF GUARD (BioMeter International, Odense, Denmark) was applied, and after stabilizing the continuous response for the ulnar nerve stimulation with a supramaximal stimulus, the baseline height of the first twitch ([T.sub.o]%) and train-of-four ratio (TOF%) were measured.
The experiment was conducted under microcosm conditions using 500 ml biometers. An amount of 100 g of soil was deposited on a non-sterilized dry base in each biometer and treated with a Roundup solution equivalent to 144 mg of glyphosate isopropylamine salt/kg of soil, plus one [sup.14]C-radiomarked solution (glyphosate isopropylamine salt, SIGMA; specific activity: 2.2 mCi/mmol to obtain an activity of approximately 2.2 x [10.sup.6] DPM (1 [micro]Ci) per 100 g of soil by biometer.

Consequently, the UVB biometer has a spectral response normalized to that at 297 nm (i.e., the normalized spectral response at 297 nm is equal to unity) and the logarithm of the normalized spectral response degrades linearly with wavelength and is ~ 0.01 at 320 nm and ~ 0.001 at 330 nm.
