In the 1980s and 1990s, foldable IOLs became the mainstay of implants due to the smaller incisions required..While the evolution of IOLs has brought us to modern day small incision phacoemulsification where the vast majority of IOLs are placed in t

This astig matism does not follow a typical kind of regular pattern. Figure 5.2d shows an irregular post laser in situ keratomi-leusis (LASIK) astigmatism. As technica

Positive spherical aberration occurs in an optical system when marginal rays are focused in front of paraxial rays (Fig. 6.1). Nearly all
