[Alterations in ocular biomechanical properties after non-automated endokeratoplasty]

The study was undertaken to determine the parameters of corneal hysteresis in healthy individuals and patients before and after non-automated endokeratoplasty. An Ocular Response Analyzer (Reichert Inc., USA) was used to study ocular biochemical properties. At the same time, the value of corneal hysteresis (mm Hg) and the central corneal thickness (microm) were evaluated. The study demonstrated lower corneal hysteresis in primary and secondary corneal dystrophy than that in normal eyes.
