Graft biomechanics following three corneal transplantation techniques

Graft Biomechanics Following Three Corneal Transplantation Techniques

PURPOSE To compare corneal biomechanical properties following three different transplantation techniques, including Descemet stripping automated endothelial keratoplasty (DSAEK), deep anterior lamellar keratoplasty (DALK) and penetrating keratoplasty (PK) in comparison to normal eyes. METHODS This cross-sectional comparative study included 118 eyes: 17 eyes of 17 patients received DSAEK, 23 e...

graft biomechanical properties following three corneal transplantation techniques

purpose: to investigate the biomechanical features of transplanted corneas after penetrating keratoplasty (pk), deep anterior lamellar keratoplasty (dalk), and descemet stripping automated endothelial keratoplasty (dsaek) and compare these measurements with those of a normal group. methods: forty-five eyes of 36 patients underwent pk, 23 eyes of 21 patients received dalk using anwar’s big bubbl...

Changes in corneal biomechanics following different keratoplasty techniques

PURPOSE To evaluate corneal biomechanics with the Ocular Response Analyzer (ORA; Reichert Ophthalmic Instruments, Depew, NY) after penetrating keratoplasty (PK) and deep anterior lamellar keratoplasty (DALK). SUBJECTS AND METHODS Sixty-three eyes of 63 patients were included in this prospective comparative study. Patients were divided into 3 groups: the first included 21 eyes of normal subjec...

corneal 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...
