Measuring the anterior chamber diameter (AC) is important both for diagnostics and before ocular surgery. In clinical practice, horizontal AC diameter is usually estimated on the basis of measurements of corneal diameter (so-called white-to-white [WTW] distance). The usual method for selecting an appropriate size for an AC lens is to add 1 mm to WT...

Cataract often coexists with pathologies of the vitreous body. Moreover, after several months after vitrectomy, the lens becomes opaque. Lens opacities interfere with appropriate visualisation of the vitreous chamber and the eye fundus, which makes performing vitreoretinal procedures difficult. For this reason, in such patients, a combined procedur...

Angiogenesis plays a very important role in development and survival of the organism.
