  Purpose

Progenitor limbo sclerocorneal cells have properties of proliferation and differentiation to corneal and conjunctival epithelium. This cells can be isolated and ex vivo expanded using cell culture technics that could permit the biological replacement of damaged ocular surface.


Condition Intervention Phase
Unilateral Limbic Insufficiency
Procedure: biological replacement corneal surface
Phase 2

Study Type: Interventional
Study Design: Endpoint Classification: Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Regenerative Medicine in Ocular Surface: Application of Cell Therapy for Ocular Surface Repair Using Progenitor Autologous Cells of Sclerocorneal Limbus Amplified ex Vivo

Primary Outcome Measures:
  • Visual Acuity [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    visual acuity improvement


Secondary Outcome Measures:
  • Improvement in appearance of ocular surface [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    presence of corneal epithelium de novo

  • lack of scar tissue in ocular surface [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • decrease of preexisting corneal vascularization [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • Improvement of corneal transparency [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • absence or decrease of corneal conjunctivalization [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    the amount of caliciform cells using impression cytology will be compare between screening and 6 months visit

  • adverse events [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]

Enrollment: 10
Study Start Date: November 2011
