Quantification of Collagen Ultrastructure after Penetrating Keratoplasty – Implications for Corneal Biomechanics
PURPOSE To quantify long-term changes in stromal collagen ultrastructure following penetrating keratoplasty (PK), and evaluate their possible implications for corneal biomechanics. METHODS A pair of 16 mm post-mortem corneo-scleral buttons was obtained from a patient receiving bilateral penetrating keratoplasty 12 (left)/28 (right) years previously. Small-angle x-ray scattering quantified col...
متن کاملcorneal graft biomechanics after penetrating keratoplasty in keratoconus
purpose: to evaluate corneal hysteresis and corneal resistance factor in penetrating keratoplasty grafts in a group of keratoconic eyes using the ocular response analyzer (ora) and to evaluate the relationship between donor size, donor-recipient disparity and central graft thickness (cgt), and ora parameters. methods: this cross-sectional study was conducted on 34 eyes of 34 keratoconus patient...
متن کاملCorneal dioptric power after penetrating keratoplasty.
The dioptric power of the cornea (spherical equivalent) was studied in 60 eyes operated on for penetrating keratoplasty. In order to determine the possible influence of (1) the underlying pathology, (2) the presence of neovascularisation, or (3) the size of the graft the sample was divided into four groups, with the following results: group A (keratoconus, same-sized graft) = 42.25 D; group B (...
متن کاملCorneal trephining for penetrating keratoplasty.
MANY complications following corneal grafting procedures may be attributed to the technical and biological problems associated with this type of surgery. It is generally agreed that accurate apposition of the graft to the margin of the incision in the recipient cornea is of the greatest importance. Manual trephining for penetrating keratoplasty frequently results in badly cut grafts, and for th...
متن کاملPenetrating keratoplasty for corneal ectasia after laser in situ keratomileusis.
PURPOSE To improve the visual acuity of patients with progressive keratectasia following laser in situ keratomileusis (LASIK). METHODS Five eyes of four patients underwent penetrating keratoplasty for ectasia after LASIK: In one patient the second eye was operated on 10 months after the first keratoplasty. The pre- and postoperative refraction, best spectacle-corrected visual acuity, and topo...
