A Comparative Study of Masking Fluids for Excimer Laser Phototherapeutic Keratectomy

Absorption of 193- and 213-nm Laser Wavelengths in Sodium Chloride Solution and Balanced Salt Solution

“…19 Desirable properties of a masking agent for phototherapeutic keratectomy include moderate viscosity and high absorbance. 12 The results of our study show that the solid-state laser wavelength of 213 nm is weakly absorbed in BSS and 0.9% sodium chloride solution compared with the 193-nm excimer laser wavelength. The increased penetration depth of the 213-nm wavelength may affect the suitability of these solutions as masking fluids for phototherapeutic keratectomy procedures.…”

Dual Laser-Assisted Lamellar Anterior Keratoplasty With Top Hat Graft

“…13 However, to our knowledge, ours is the first study in which excimer laser smoothing has been used to improve the smoothness of the graft-host interface surfaces in anterior lamellar keratoplasty. Clinical studies will be necessary to determine whether this smoothing technique translates into reduced postoperative scarring and haze formation, and improved interface clarity and visual outcomes in vivo.…”

Phototherapeutic keratectomy

“…In a comparative study involving 38 eyes with progressive KC, superior visual and refractive outcomes were obtained in cases where CXL was preceded by TE-PTK for epithelial removal rather than mechanical epithelial removal (Table 1). 86 In the eyes with TE-PTK, the mean UDVA and corrected visual acuity improved from 0.99 AE 0.71 and 0.30 AE 0.26 logarithm of the minimum angle of resolution preoperatively to 0.63 AE 0.42 (P ¼ 0.02) and 0.19 AE 0.18 logarithm of the minimum angle of resolution (P ¼ 0.008), respectively, 12 months after the operation. The eyes in which the epithelium was mechanically removed did not have a significant improvement in visual acuity.…”
