Abstract Details


To evaluate early results of topography-guided Photorefractive Keratectomy (TGPRK) for keratoconus with Schwind Amaris.


Pacific Laser Eye Centre, Vancouver, BC, Canada


Retrospective series. Evaluate outcome of keratoconus eyes underwent treatment with Schwind Amaris Excimer laser. Pre-operatively and post-operative uncorrected visual acuity (UCVA), corrected distance visual acuity (CDVA), manifest refraction (MR) and topographic cylinder were analyzed. Eyes with at least 12 months of follow-up were included.


254 eyes with keratoconus underwent treatment with 133 had sufficient data at 12 months for analysis. 71 of 133 (53%) showed UCVA ≥20/40 post-operatively. 61 (46%) had improved CDVA and 29 eyes (22%) gained two or more lines (p=0.0003). No patient showed progression. Mean astigmatism was reduced from 3.06±1.83D to 1.64±1.58D (p<0.0001). Mean spherical equivalent was improved from -3.07±3.85D to -0.88±2.68D (p<0.0001).


Early results of TG-PRK with Schwind Amaris show efficacy and safety as treatment for eyes with keratoconus. More than half had UCVA 20/40 or better post-operatively. Almost half had improved CDVA. Almost one quarter had CDVA improved two or more lines. This study demonstrates an alternative treatment for keratoconus with contact lens intolerance.
