ABSTRACT
This chapter discusses the protocols and designs have ranged from classic monovision, multifocal intraocular lens (IOL), and accommodating IOLs. The determination of IOL power required for a particular postoperative refraction is dependent on the axial length of the eye, the optical power of the cornea, and the predicted location of the IOL within the eye. Calhoun Vision has developed a silicone IOL that allows for noninvasive power adjustment postimplantation. Calhoun Vision’s light adjustable lens (LAL) is based on the inclusion of a proprietary photoreactive silicone macromer and photoinitiator within a medical grade silicone polymer matrix. Knowledge of the spatial irradiance profile applied to the LAL coupled with the analysis of the altered wavefront using both measurement methods allows guidance in the modification of the pattern to produce the desired changes. Calhoun Vision has developed the LAL that provides cataract surgeons a method to effectively and noninvasively adjust the refractive error postimplantation and optimize visual outcomes.
