PURPOSE: To evaluate the safety and effi cacy of the ALLEGRETTO WAVE excimer laser system (WaveLight Laser Technologie AG, Erlangen, Germany) in LASIK for hyperopia and hyperopic astigmatism. METHODS:One hundred twenty consecutive LASIK cases for hyperopia with or without astigmatism treated with the ALLEGRETTO WAVE excimer laser were prospectively evaluated up to 12 months postoperatively. Patients were allocated into three groups according to their refractive sphere and cylinder: a low hyperopia group, with up to ϩ3.00 diopters (D) sphere and astigmatism рϩ1.00 D (n=52); a moderate hyperopia group with ϩ3.25 to ϩ5.00 D sphere and astigmatism of рϩ1.00 D (n=45); and a high hyperopia/toric group sphere уϩ5.25 D or cylinder у1.25.D (n=23). Flaps were created with the Moria M2 microkeratome (Moria, Antony, France). Parameters evaluated were pre-and postoperative refractive error, uncorrected visual acuity, best spectacle-corrected visual acuity (BSCVA), higher order aberration change, and contrast sensitivity.
