A 50-year-old woman had implantation of intrastromal corneal ring segments for recurrent keratoconus 15 years after penetrating keratoplasty. Two segments (0.15 mm and 0.25 mm) were inserted without any intraoperative or postoperative complications, using the femtosecond laser to create the tunnels (superior and inferior). Ten months after the procedure, the uncorrected visual acuity was 20/100...
We report a second clinico-pathologic report of recurrent keratoconus in a 43-year-old white female with bilateral penetrating keratoplasties for keratoconus. She was found to have a recurrence of this condition in the right eye as manifested by increasing myopic oblique astigmatism, subepithelial and anterior stromal scarring and corneal thinning, 22 years following the initial grafting proced...

Slit lamp biomicroscopy revealed graft ectasia together with Vogt's striae in the posterior stroma and...
PURPOSE To report and discuss cases of lamellar keratoplasty using corneas obtained during previous penetrating keratoplasty in keratoconus eyes. METHODS Corneal buttons were obtained from 7 keratoconus patients and stored in a preserving solution for 7-60 days (average, 32.4 days) before use. The recipient eyes comprised recurrent pterygium 3 eyes, primary pterygium 1 eye, pseudopterygium 1 ...
