Abstract Details


Wavefront-guided LASIK is one of the most precise and individualized refractive procedures. Nevertheless it is still discussed controversy. Aim of the study was to evaluate first results of the wavefront-guided LASIK procedure powered by the diagnostic device iDesign.


EuroEyes, Clinic for refractive surgery, Hamburg, Germany


In a prospective study 212 eyes of 106 myopic patients were treated by wavefront-guided Femto-LASIK with the VISX S4 IR Laser and the new iDesign aberrometer technology. All eyes were targeted for emmetropia. Follow up time was 3 months. Spherical equivalent was -4,14 +/- 2,44 Dpt, range from -1,0 to -10,0 Dpt. Visual acuity (UCVA, BCVA), postrefraction and amount of higher order aberrations as well as efficacy, safety, stability and predictability were evaluated. Patient satisfaction was analyzed.


Uncorrected visual acuity improved from 0,24 to 0,96, efficacy-index was 0,94. Stability after 3 month was 0,06 ± 0,43. 79% were within +/-0,5 Dpt, 96% within +/- 1,0 Dpt. No eye had a loss of 2 or more lines of BCVA. Total amount of higher order aberrations was less than in literature compared LASIK-studies.


Wavefront-guided iDesign Femto-LASIK is an effective and safe procedure. A quite good UCVA even in eyes with higher postrefraction level was remarkable. Higher resolution during diagnostic procedure with a high-definition Hartmann-Shack wavefront sensor seems to improve patient satisfaction.
