Purpose
To investigate the outcomes induced by anterior surface normalization by wavefront-guided transepithelial photorefractive keratectomy (CW-TPRK) in conjunction with corneal cross-linking (CXL) in a keratoconus patient with radial keratotomy (RK).
Setting
Veni Vidi Eye Hospital, Istanbul, Turkey
Methods
CW- TPRK in conjunction with accelerated CXL was performed to a 38 years old male patient who previously had radial keratotomy for keratoconus for normalization of aberrations. Refractive, topometric, pachymetric, abberometric and visual rehabilitation changes induced by the treatment were analyzed.
Results
The patient had operation in OD and 2-year follow-up results were analyzed. Pre and post-operative refractive errors were -5.25 D (-1.25D at 20 degrees) and -1.50 D (-2.00 at 11 degrees) consecutively. Average K at 3 mm was decreased from 46.12 D to 45.58 D. CCT was decreased from 490 microns to 446 microns. Coma and higher order aberrations at 6mm were decreased from 2.56, 2.78 microns to 1.11 and 1.24 microns consecutively. Corrected distant visual acuity increased from 0.4 to 1.0 Snellen lines.
Conclusions
Wavefront-guided transepithelial photorefractive keratectomy was safe and effective in correcting aberrations and refractive errors in a keratoconus patient with radial keratotomy.
