Central Corneal Thickness Measurements

Pre-LASIK
 Post-LASIK
Mean ± SD (μm) Range (μm) Mean ± SD (μm) Range (μm)
US 553.3±33.0 489–607  498±46.6 405–574
OCTMean 546.9±29.4 477–599 513.7±44.5 437–587
OCTMin 540.1±29.6 471–584 504.4±44.9 424–580

OCT = optical coherence tomography; OCTMean = average OCT corneal thickness over the central zone (diameter < 2 mm); OCTMin = minimum OCT corneal thickness over the central zone; SD = standard deviation; US = ultrasound pachymetry.
