Abstract Details


To compare the uses of two wavefront aberrometers in wavefront-guided laser in situ-keratomiluesis (WFG-LASIK) for correcting refractive error following implantation of diffractive multifocal intraocular lenses (IOL).


Department of Ophthalmology, Tokyo Dental College Suidobashi Hospital


The retrospective study included 40 eyes of 32 patients who underwent WFG-LASIK for refractive and astigmatic error corrections. Preoperative examinations were performed using aberrometers WaveScan and iDesign (Abbott Medical Optics, N=16 and 24, respectively). Rates at which the WFG-LASIK was selected in the preoperative examinations (WFG-LASIK rate) and iris registration activated during ablations (IR rate) were calculated. Manifest refractions, visual acuities before and after WFG-LASIK, and postoperative contrast sensitivity were compared.


WFG-LASIK rate was 50.0% with the uses of WaveScan, and 75.0% with iDesign. Although IR rate was 31.3% with WaveScan, the use of iDesign increased to 83.8%. With the uses of WaveScan and iDesign, the amount of manifest cylinder was reduced significantly after WFG-LASIK treatment from -0.97±0.78 and -1.07±0.64 D to -0.30±0.34 and -0.36±0.34 D, respectively (p=0.001 and 0.0002). There were no significant differences in the manifest refractions, visual acuities, and contrast sensitivity between the aberrometers.


WFG-LASIK with the use of the new wavefront aberrometer was effective for refractive error corrections on eyes implanted diffractive multifocal IOLs.
