Lamellar Transplant With Lyophilized Corneas

Randomized Clinical Trial for Lamellar Transplants Using Lyophilized and Optisol Corneas

- The goals of this study are to develop a lyophilization method for anterior lamellar transplants in Brasil and to make a comparative analysis among patients transplanted with lyophilized and optisol corneas

• 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.

Inclusion Criteria:

• Keratoconus patient
• BCVA < 20/60
• No systemic diseases
• Who signed the inform consent

Exclusion Criteria:

• BCVA > 20/60
• Presence of deep opacities
