Summary: Evaluation of visual functions after laser correction of ammetropia 1. We evaluated the quality of vision of 55 pacients (110 eyes) with myopia from - 0,5 dpt to -6,00 dpt after laser correction with PRK and LASIK. We compaired the results between group A after laser correction with the excimer laser Esiris (Schwind, Germany) and group B after correction with Amaris (Schwind, Germany). We investigated subjective visual perception, standardized visual acuity and contrast sensitivity under photopic and mesopic conditions as well as glare sensitivity at 1, 3, 12 and 24 months postoperatively. 2. Subjective perception: One month after the procedure, there were significant differences in questions concerning the overall visual quality, while watching TV and driving during the day and at night, with group B patients significantly more satisfied. Twelve months after the procedure, 100% of the patients of both groups were satisfied with their quality of vision. 3. Visual acuity: In group A, photopic and mesopic visual acuity significantly decreased 1 month after the procedure and then increased and differed only insignificantly from the preoperative values. In group B, photopic and mesopic visual acuity was changing insignificantly upto 3 months after the procedure and then increased significantly to...
