[An evaluation of the biomechanical parameters of the corneoscleral eye coating in kerato-refractive surgery].
The parameters characterizing the mechanical properties of the cornea and of the adjoining scleral parts as well as the influence produced by radial keratotomy and excimer laser kerato-ablation on the rigid corneal features were studied. The conclusion is that such keratorefractive surgeries (radial keratotomy and excimer laser photo-ablation) worsen the resistant corneal properties. Although the corneal thickness remains unchanged after radial keratotomy, "conditionally weak" sections take shape in the zone of keratotomic scars, in which the probability of ruptures of the cornea at damages to the eyeball increases.
