Table of Contents

Understanding optics -- Astigmatism analysis : vector analysis to chart residual astigmatic error can improve the accuracy of refractive surgery -- Aspheric treatments reduce spherical abberation after cataract, refractive surgery : implanting an aspheric IOL or incorporating a prolate laser treatment into corneal refractive surgery helps reduce spherical abberation -- Vertex distance, refraction and intraocular lens power calculations : measuring vertex distance and performing over-refraction with a soft contact lens for higher prescriptions can reduce refractive surprises after IOL implantation -- Intraocular lens calculations after surgery : surgeons implanting intraocular lenses in patients who have undergone corneal refractive surgery must be precise in their measurements and calculations -- Surgical correction of presbyopia : some newer refractive surgical modalities take advantage of pupil size changes and other factors to provide good near and distance vision -- Optical improvements in excimer laser surgery : refinement of the radial compensation function and other optical concepts have helped to improve LASIK outcomes -- Zernike and Fourier polynomials : describing surfaces -- Ocular and topographic wavefront -- Understanding neural adaptation.
