Information provided by:
Democritus University of Thrace
A study of flap thickness predictability in patients submitted to Laser in Situ Keratomileusis (LASIK) with the Carriazo-Pendular microkeratome (130 micrometers head size).

Condition Intervention
Corneal Flap Thickness (Micrometers) Device: Carriazo Pendular microkeratome

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Retrospective
Official Title: LASIK Flap Thickness Predictability With the Carriazo Pendular Microkeratome

Further study details as provided by Democritus University of Thrace:

Primary Outcome Measures:
  • Corneal flap thickness (micrometers) [ Time Frame: 6 months postoperatively ]
    Flap thickness was calculated by subtracting the preoperative central corneal thickness minus the intraoperative residual stromal thickness. All measurements were made using ultrasound pachymetry (non-interventional technique).

Enrollment: 131
Study Start Date: February 2006
Study Completion Date: February 2009
Primary Completion Date: February 2007 (Final data collection date for primary outcome measure)
