Aspheric IOL implantation markedly reduced spherical aberration and vertical coma, but the decrease in aberrations may have correlated with an undesirable reduction in depth of focus. “The results in ...

In the current age of refractive cataract surgery, we measure the quality of vision in addition to the quantity of vision. The patient’s image quality is as important as his or her Snellen acuity, ...

The goal of attaining high-quality, spectacle-free reading and distance vision after cataract surgery—without annoying optical side effects—has proved elusive to date. Although clinical studies of ...

When bilateral cataract surgery becomes necessary, many patients are faced with the alluring prospect of reducing or even eliminating the need to use spectacles for distance and near vision. Patients ...

The measurement technique of the aspheric surface is mainly for the surface form and parameters. The surface form is the three-dimensional distribution of the surface in the spatial domain. The ...
