Abstract
Purpose: Outcome of topography?guided excimer laser ablation in conjunction with accelerated, high?fluence cross?linking in corneal ecstatic disease using the NIDEK CXIII equipped with CATz algorithm from the FinalFit software棓Bharat Protocol.� Methods: Retrospective case record review of 30 eyes of 17 patients of stage 1?3 keratoconus who underwent the procedure was performed. Data collected were for visual acuity, distortion?induced eye pain, and keratometry. Pachymetry, lower order and higher order aberrations, spherical aberrations, and topographic cylinder were documented from by Scheimpflug imaging (Pentacam 70700: Oculus, Wetzlar, Germany). Results: At a minimum follow?up of 6 months (range 6.2� months), there was significant improvement in UCVA (P < 0.00001), BCVA (P = 0.0061), decrease in Kmax (P = 0.0349), Ksteep (P < 0.0411), Kflat (P = 0.0099), and pachymetry (P = 0.0001). Significant improvement was also seen in distortion?induced eye pain (27/30 to 2/30; P < 0.00001). A more than two?line improvement in UCVA and BCVA was seen in 23/30 and 17/30 cases, respectively. Ectasia was stabilized in all cases at the last follow?up, and no complications were seen. Conclusions: The 揃harat� Protocol to arrest keratectasia progression and improve corneal regularity is a safe and efficacious alternative as a keratoconus management option. This is the first such study on Nidek Platform for the same.
