Abstract Details


To evaluate the clinical outcomes obtained after wavefront-guided laser in situ keratomileusis (LASIK) in eyes with myopic astigmatism using measurements obtained with the high resolution aberrometer iDesign (Abbott Medical Optics) to define the customized ablation profile.


Instituto Clínico-Quirúrgico de Oftalmología, Bilbao, Spain


A total of 16 eyes of 10 patients ranging in age from 23 to 37 years were enrolled in the study. All eyes underwent wavefront-guided LASIK surgery with the VISX Star S4IR excimer laser (Abbott Medical Optics) for the correction of myopic astigmatism using a customized ablation profile defined according to the measurements obtained with the high resolution aberrometer iDesign. Visual, refractive, aberrometric and ocular scattering (OQAS system, Visiometrics) changes were evaluated during a 1-month follow-up.


Mean sphere was reduced significantly from a mean preoperative value of -2.72±1.22 to +0,07±0.30 D postoperatively (p<0.001). Similarly, manifest cylinder was reduced from -1.58±0.50 preoperatively to -0.13±0.23 (p<0.001) at 1 month postoperatively. Postoperative sphere and cylinder was within ±0.50 D in 100% of eyes. All eyes achieved a postoperative uncorrected and corrected distance visual acuity of 20/25 or better. No significant changes were detected in high order (p=0.96), coma (p=0.65) and spherical aberrations root mean square (p=0.43). No significant changes were found either in the ocular scattering index (p=0.24)


Wavefront-guided LASIK using the high aberrometer iDesign is an effective and safe method for the correction of myopic astigmatism, preserving the patient’s visual quality.
