Abstract EN
Purpose.
To evaluate the visual, refractive, and topographic outcomes after simultaneous topography-guided transepithelial photorefractive keratectomy (transepithelial TG-PRK) using the Amaris Excimer laser platform and accelerated corneal cross-linking (CXL) in eyes with keratoconus.
Materials and Methods.
Patients with 2 years of follow-up were included in this retrospective case series.
Manifest refraction (MR), uncorrected (UDVA) and corrected (CDVA) distance visual acuity, corneal topography, and pachymetry were evaluated at 1, 3, 6, 12, and 24 months after surgery.
The root-mean-square of total higher-order aberrations (total HOA-RMS), coma (Coma-RMS), and spherical aberration (SA-RMS) were calculated for 4- and 6-mm diameters.
Results.
Forty-six eyes of 46 patients were included in the study.
Stromal ablation was ≤50 μ in all patients.
MR was −3.78±3.26 preoperatively and −1.39±1.82 postoperatively.
Significant improvements were seen in the UDVA and Coma-RMS values at 1 month, CDVA and total HOA-RMS values at 3 months, and SA-RMS values at 1 year compared to preoperative levels.
UDVA values further improved after 2 years, compared to the 1-year values.
No patient lost two or more lines and keratoconus progression was not observed in any patient.
Conclusion.
Simultaneous transepithelial TG-PRK and accelerated CXL resulted in significant gains in CDVA without compromising CXL efficacy.
