Abstract Details

Purpose:

To investigate the morfologicl and biomechanical changes in the sclera after exposure to diode laser in the experiment.

Setting:

The S. Fyodorov Eye Microsurgery Federal State Institution, Russia

Methods:

The study included 6 isolated fragments of human cadaver sclera of 6 eyes aged 60 to 70 years. [Axial length (AL) is 23.56 ± 3.06mm]. Samples of sclera were cut out with a microsurgical blade from the posterior pole of the eye, then the scleral fragments were exposed to the diode laser ALOD-1 (Russia) (energy E=900mJ, exposure time 5sec). Fragments of the sclera treated earlier by the laser were cultivated in the medium and then transported to a laboratory for biomechanical testing on an Instron testing machine, and morphological studies using electron microscope Quanta 200 3D

Results:

The study of biomechanical properties of posterior pole sclera after the exposure to diode laser showed an increase in strength and indices Jung's modulus (JM) in all tissuef the eye

Conclusions:

Diode laser exposure leads to pronounced morphological changes in the scleral tissue.
