Abstract Details

Purpose:

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.

Setting:

Instituto Clínico-Quirúrgico de Oftalmología, Bilbao, Spain

Methods:

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.

Results:

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)

Conclusions:

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.
