Purpose

To evaluate the visual, refractive and topographic outcomes of combined cone apex centered trans-epithelial phototherapeutic keratectomy (T-PTK) with accelerated corneal collagen cross-linking (CXL) in keratoconus (KCN)

Setting

Prospective interventional study

Methods

32 treatment- naïve eyes of patients with progressive KCN underwent customized cone apex centered T-PTK with accelerated CXL. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), manifest refraction, keratometry (K) values, epithelial thickness and corneal aberration profile were documented at baseline and at 1, 3, 6 and 12 months post-operatively

Results

UCVA, BCVA and manifest refraction showed significant improvement at 12 months follow up (P <.001). Keratometric outcomes with flat and steep K were not significant although maximum keratometry (Kmax) showed significant improvement at the end of one year (P=0.03). Corneal aberration profile showed significant improvement in the total root mean square (RMS), RMS higher order aberration, spherical aberration and vertical coma by the end of one year (P=0.01).

 

Conclusion

Cone apex centered PTK with accelerated CXL using customized ablation for the treatment of keratoconus provides good visual, refractive and topographic outcomes.
