Optical biometry provides information about the length of the eyeball and the distances between successive elements of the eye. During the examination, the cornea, lens, and retina can also be imaged along the measuring beam. It evaluates the width of the angle of seepage, adhesions in this angle, closure of the angle by the lens, etc. it also helps to find out any differences in the length of the eyeballs.

This is one of the basic tests recommended for diagnosis before laser vision correction or implantation (implantation) of artificial lenses. In some forms of glaucoma, it is critical to decide whether to use laser or surgery. Ultrabiomicroscopy is the most precise method of examining tumors, cysts and also examining the patency of postoperative fistulas, i.e. the effects of surgery. It can be performed even when the cornea is completely cloudy.

The examination is performed while lying down. The patient’s eye is anesthetized, and a plastic fork filled with water is placed over the eye, where an ultrasound probe penetrates the anterior segment of the eye. The doctor sees the objects under examination on a computer monitor.

The test is performed without the need for a pupil dilator. Optical biometrics does not require direct contact with the eyeball. It is based on the technique of optical
coherence tomography (OCT)
