| Summary: |
Purpose: The aim of
this study was to examine in-vivo corneal morphology 10
years after photorefractive keratectomy (PRK).
Material and Methods: We analyzed 96 corneas of
60 patients (20 women and 40 men in age 23-49 years),
who underwent PRK for myopia and myopic astigmatism. The
spherical equivalent of the refractive error before
surgery ranged from -6.75 D to -2.0 D. Confocal
microscopy examinations were performed before and during
10 years of follow-up.
Results: Confocal microscopy showed alterations
within the epithelium and anterior part of corneal
stroma characteristic for state after photoablation. In
74% of eyes blurred structures of collagen fibers,
increased reflectivity were observed. In three patients
in the anterior part of corneal stroma the cicatrical
tissue was observed. The Bowman’s membrane was absent in
the central area, but regenerated subepithelial nerve
plexus was detected.
Conclusions: In-vivo, corneal morphology after
PRK showed alterations within its structure still 10
years after surgery. Subclinical lesions of corneal
structure detected by microscopic examination in clear
corneas do not seem to affect post-PRK visual acuity. |
