Table 2 Intended and achieved corneal incision depth in porcine eyes that underwent micro-RK

From: Accuracy and safety of partial thickness femtosecond laser radial and arcuate keratotomy incisions in porcine eyes

Intended corneal incision depth Number of measures Achieved micro-RK corneal incision depth MAE (intended-achieved) in incision depth ± SD (µm)
Mean ± SD (%) Median (%) Range (%)
50% of corneal thickness 40 50.01 ± 1.72 49.83 47.10–53.75 12.66 ± 8.25
80% of corneal thickness 40 77.69 ± 1.78 77.18 74.17–81.55 23.33 ± 14.77
  1. Five porcine eyes were used in each set. Four micro-RK incisions were performed in each eye and two measurements were taken for each RK incision making a total of 40 measurements in each set
  2. MAE mean absolute error; RK radial keratotomy; SD standard deviation
