Purpose

To evaluate the outcomes of TREK and TCAT followed by corneal crosslinking (CXL) in keratoconus patients using the SCHWIND Amaris 1050RS excimer laser and the Foresight software, which preoperatively predicts post-treatment topography. The study aims to assess visual, refractive, and topographic improvements, along with corneal stability over six months.

Setting

  • Prospective interventional study

  • Sample Size: 50 keratoconic eyes

  • Study SIte: Tertiary eyecare institute

Methods

A prospective study including 50 keratoconic eyes undergoing TREK & TCAT for corneal surface regularization, followed by CXL. The Foresight software is used for preoperative topographic prediction. Parameters including uncorrected (UCVA) and best-corrected visual acuity (BCVA), refraction, keratometry, specular count, and disease progression are assessed preoperatively and at 1, 3, and 6 months postoperatively.

Results

Preliminary data suggests significant improvement in UCVA and BCVA with reduced refractive error. Keratometric values show corneal regularization with reduced asymmetry. 

More results TBD

Conclusions
