Abstract Details


To evaluate the Ocular Scatter Index (OSI), a measure of point spread function, of different shot patterns in Trans epithelial photo-refractive keratectomy, PRK using SCHWIND AMARIS (SA)


Pacific Laser Eye Centre, Vancouver, BC, Canada


30 eyes treated with the original SA transepithelial PRK shot-pattern compared to 30 eyes treated with the improved shot-pattern (SmartSurfACE). In all cases standard examinations, pre- and postoperative corneal-wavefront analyses (SCHWIND SIRIUS), and ocular-scattering index (HD Analyzer) were performed. Optimized astigmatic corrections were evaluated in terms of efficacy, predictability, stability, safety, and aberrations outcomes.


Ocular Scatter, OSI, was less for SmartSurfACE than original SA transepithelial PRK shot-pattern at 0.99 vs 2.68 respectively (p<0.01) . UDVA and CDVA were better with SmartSurfACE at all time points up to 1 month post operatively (p<0.05), and became comparable to the original SA transepithelial PRK shot-pattern at 3M postop (p>0.05). UDVA immediately after surgery 0.38±0.19logMAR for SmartSurfACE (90% at 20/63 or better, and 23% were 20/32 or better) compared to 0.84±0.21logMAR for the original AMARIS transepithelial PRK shot-pattern with 18% ≥20/63 (p<0.01). Postoperative refractions were similar (p>0.05) in both groups (SE +0.05±0.20D; astigmatism -0.3±0.3D).


Ocular scatter was significantly better with after improving the shot-pattern of the Schwind Amaris as SmartSurfACE upgrade Visual recovery (CDVA, UDVA) was also superior up to one month post operatively compared to the original AMARIS transepithelial PRK shot-pattern.
