Abstract Details


To evaluate the clinical outcomes of FS-LASIK surgery for the correction of myopia performed with the Advanced CustomVue excimer laser platform with high resolution aberrometer.


Department of Ophthalmology, TiangJin Medical University General Hospital , China


A total of 102 eyes from 51 patients with myopia ranging from -1.00 to -12.63 D and astigmatism of no more than -5.00D were enrolled in this study. All cases underwent WFG LASIK using VISX STAR S4 IR excimer laser and iDesign system.Manifest spherical equivalent refraction, uncorrected and spherical-corrected visual acuity�ï�¼�Œhigh-order aberration(HOA) were assessed at 1 month and 3 months after surgery.


Mean refraction was -0.14�Â�± 0.60D and -0.18�Â�± 0.57D at 1 and 3 months postoperatively,and mean LogMAR CDVA was -0.04�Â�±0.06 and -0.03�Â�±0.05. At 3 months postoperatively, 95% were within�Â�± 1.00D and 98% were within�Â�±2.00D. 21% of cases gained more than 1 line of CDVA whereas 2% of cases dropped 1 line.�ã�€�€Preoperative mean HOA RMS and spherical aberration(SE) were 0.19�Â�±0.10�Â�µm and 0.04�Â�±0.07�Â�µm, 1 month after surgery, HOA RMS and SE were 0.19�Â�±0.16 and 0.06�Â�±0.07�Â�µm. There were no significant differences between before and after surgery in HOA and SE (P>0.05).


WFG-LASIK using high resolution aberrometer yielded effective, safe and predictable results for the correction of mild to high myopia.The high order aberration and spherical aberration after WFG-LASIK were comparable to that before surgery.
