Table 1 Preoperative corrected distance visual acuity, spherical equivalent and refractive astigmatism mean value in Groups 1 and 2

From: Refractive outcome of keratoconus treated by big-bubble deep anterior lamellar keratoplasty in pediatric patients: two-year follow-up comparison between mechanical trephine and femtosecond laser assisted techniques

  CDVA (logMAR) Spherical equivalent (D) Refractive astigmatism (D)
Group 1 0.5 ± 0.1 −12.0 ± 3.1 7.0 ± 2.0
Group 2 0.4 ± 0.2 −10.0 ± 4.2 6.0 ± 1.8
P value 0.7 0.9 0.4
  1. CDVA = corrected cistance visual acuity; D = diopters
  2. The P value of paired Student t-test was considered significant if it was less than 0.05
