Abstract Details

Purpose:

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)

Setting:

Pacific Laser Eye Centre, Vancouver, BC, Canada

Methods:

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.

Results:

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).

Conclusions:

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.
