Abstract Details

Purpose:

To develop a new surgical keratectasia classification.

Setting:

The S. Fyodorov Eye Microsurgery Federal State Institution

Methods:

The analysis of clinical and functional condition of 1010 eyes of 587 patients with keratectasia before and after 1215 different type surgeries (UV-crosslinking, ICRS implantation, DALK, PK, PRK and phaco with TIOL implantation). Pre- and post-surgical examination included standard (visometry, biomicroscopy, keratotopography) and specific (OCT, confocal microscopy, scanning topography) methods.

Results:

Keratectasias were classified according to: presence of the ectatic process progression (progressive and stable); type of ectasia (primary and secondary); ectasia symmetry (symmetrical and non-symmetrical); stage (I, II, III and IV). It is recommended: subclinical stage – supervision and dynamics control; I stage – UV-crosslinking; II stage – ICRS implantation, UV-crosslinking only if residual ametropia correction by PRK or TIOL implantation is planned; III stage – DALK; IV stage – PK.

Conclusions:

The developed keratectasia classification, based on modern diagnostic methods, allows determination of the tactics of surgical treatment, depending on pathological process type and stage.
