LASIK Flap Thickness-Is Thin Better?
Top LASIK Surgeons are always seeking ways to improve the safety, efficacy and predictability of LASIK. Researchers from the University of Utah compared LASIK results when using two different “flap” thicknesses to see if there were any clinical advantages in visual acuity, contrast sensitivity, higher order ocular aberrations or quality of life. Researchers reporting in the April 2011 edition of the Journal of Refractive Surgery compared the visual results of a group of 94 patients who were treated with LASIK using a different “flap” thickness in each eye so that 47 eyes had one thickness and 47 eyes had a different thickness. After three months it was concluded that both “flap” thicknesses used for LASIK treatment provided similar clinical results. There were no statistically significant differences between the flap thicknesses in terms of overall visual acuity, increase or decrease in aberrations or contrast sensitivity and all patients reported a significant improvement in the quality of life.
