The article focuses on ability of corneal imaging in determining successful implantation of premium intraocular lens (IOL) which was earlier limited to laser refractive surgery patients. Topics discussed include use of corneal topography in finding irregular astigmatism, corneal analysis to find abnormal shape of cornea that hinders multifocal lens, abnormalities in corneal spherical aberration (SA), and K reading to determine irregularities in ocular surface.

The article focuses on the performance of Light-adjustable Lens (LAL) for the treatment of Presbyopia. It mentions that the use of the ability of the near-ultraviolet illumination to fine-tune the shape of the lens is available to LAL. It adds that the amount of spherical aberration for a particular patient can be selected with the use of adjustable lens.

The article examines factors contributing to success with multifocal contact lenses. It discusses the design principles and material considerations which are included in current lenses, including a daily disposable option: 1-Day Acuvue Moist Multifocal. It states that among aberrations of the normal human eye, spherical aberration is most relevant to multifocal contact lens correction.
