Abstract: :
Purpose: To evaluate the safety and efficacy of topography–guided LASIK treatment, utilizing the Allegretto–Wave system. Methods: 7 consecutive eyes that had LASIK and were symptomatic, underwent topo–guided treatment, based on 8 reproducible measurements. We evaluated pre–, and post–operative refraction, irregular astigmatism, cornea and flap thickness, low contrast sensitivity (LCS) and possible complications. Follow–up was 2–6 months Results: 7 eyes were included. The mean values were: refractive error: sphere: –5,00D (–0.75 to –7.50) postop –0.65 and cylinder: –3.75D (–1.25 to –4,75) postop –0.50. UCVA improved from 20/200 to 20/18. There was loss of BCVA(with RGP contacts) in 1 case. LCS improved by 150%. 3 eyes required further treatment for spherical adjustment. Conclusions: Topography–guided LASIK with the ALLEGRETTO–WAVE system for irregular eyes, appears to be safe and very effective for correction of refractive error, irregular astigmatism, and the improvement of visual function. It has demonstrated in this limited study the ability to predictably improve quality of vision. It should be viewed though as a possible 2 step procedure in regard to spherical adjustment.
