There were two errors in the letter entitled "High-Frequency Ultrasound Digital Signal Processing for Biometry of the Cornea in Planning Phototherapeutic Keratectomy," published in the April 1993 Archives of Ophthalmology (1993; 111:430-431).
• The first error appeared in the second sentence of paragraph 3, which should have read as follows: "Epithelial and stromal thickness measurements of 51 μm and 494 μm, respectively, were obtained by averaging 10 scan lines (an azimuthal distance of 300 μm)."
• The second error appeared in the legend to Figure 2, which should have read as follows:
Figure 2.Slit-lamp photograph [not high-frequency ultrasound scan] of the cornea of a 37-year-old man 6 months after photorefractive keratectomy to rectify the undercorrection of a previous radial keratotomy procedure. Proliferation of scar in the central cornea can be seen.
