To evaluate safety, efficacy, preditability and stability of visual outcomes 6 months post femtosecondlaser in situ keratomileusis (fs-LASIK) treatment of hyperopia and hyperopic astigmatism.
Department of Ophthalmology Goethe-University
retrospective clinical case series. 72 eyes of 36 patients (50% male, mean age 44, ranging from 22 to 64, mean manifest spherical equivalent: 1.90 D ± 1.01 D (from 0.38 to 4.15), mean manifest cylinder -1,09 D ± 1,05 D (from -3,81 to 0,00). Inclusion criteria were the suitability for fs-LASIK according to the German Commission of Refractive Surgery (KRC) guidelines, and full 6 months follow up examinations. Flap creation was performed with the FS60 femtosecond laser (Abbot), corneal ablation with the Amaris 500 / 750 excimer laser (Schwind) using the Aberration-Free" aspherical ablation pattern and vertex centration. Postoperative analysis included corrected and uncorected visual acuity, manifest refraction and complications.
(Preliminary results, full data will be shown at presentation.) No complications occurred. No patient lost one or more lines in corrected visual acuity, 75 remained unchanged, 25% gained one line. 80% of patients achieved an uncorrected VA of 20/20 or better, 18% of 20/16 or better, 9% of 20/16. Mean postop manifest spherical equivalent was -0.03 ± 0.30 D. 50% were within 0.25D, 75% within 0.75D, 84% within 0.75D and 94% within 1D of spherical equivalent.
fs-LASIK is a safe and predictable way of treatment of hyperopia, however not as precise as treatment of myopia.
