Wavefront-Modified IOLs

Cataract and Refractive Surgery

Part of the book series: Essentials in Ophthalmology ((ESSENTIALS))

The introduction of wavefront technology in ophthalmology has provided important insights on the effect of cataract and refractive surgery on the optical properties of the eye. In the field of cataract surgery, a primary area of interest has been the role of spherical aberration on modifying quality of vision. Positive spherical aberration occurs in an optical system when marginal rays are focused in front of paraxial rays (Fig. 6.1). Nearly all virgin human corneas have positive spherical aberration. Traditional spherical intraocular lenses (IOLs) also have positive spherical aberration, thereby adding to the positive spherical aberration of the cornea. Aspheric IOLs with negative spherical aberration have been designed to compensate for the positive spherical aberration in the cornea. This chapter will discuss a range of topics regarding aspheric IOLs, including types that are currently available, custom selection, effect of decentration, impact on depth of focus, and clinical outcomes.
