  • Topography
  • Orbscan
  • Pachmetry
  • Ultrasound Biomicroscopy

Estimated Enrollment: 20
Study Start Date: December 2005
Estimated Study Completion Date: December 2006
Detailed Description:
  • After the development of a techinique to lyophilize corneas, we randomly assingned 20 patients with keratoconus and visual acuity of < 20/60, who signed the consent term and divided them into 2 groups. One group was transplanted with lyophilized corneas and the other group with optisol corneas.
  • Patients are being followed for 6 months with visual acuity, refraction, topography, orbscan, pachmetry, ultrasound biomicroscopy and confocal microscopy.
  • Results are going to be statistically analysed by SPSS program.
