Abstract
In this chapter an apodized diffractive multifocal (MF) intraocular lens (IOL) model is presented and consists of a summary of the clinical trial involving 20 cases of patients who underwent cataract surgery and were implanted bilaterally with the SeeLens MF. A significant improvement in the uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near visual acuity (UNVA), and corrected near visual acuity (CNVA) (p < 0.01) was observed. In measurements of intermediate vision, UIVA and DCIVA, no changes were observed. With respect to defocus curve provides maximum viewing two peaks, one for distance and one for near. Between these two peaks has a slight slope which generates an adequate and functional intermediate visual acuity. Regarding optical quality outcomes a significant reduction of higher order internal aberration and also a significant increase of the ocular Strehl ratio was observed. SeeLens MF IOL provides great results in far and near vision in addition to a functional intermediate vision at optimal performance of intraocular optical quality, so this is an appropriate option IOL within the different alternatives for cataract surgery.
In addition, in this chapter we also present another MF IOL that belongs to the Hanita family, the BunnyLens MF. This MF IOL also has an apodized diffractive optic and four points haptic design, which provides excellent centration. Both the SeeLens and the NunnyLens MF IOL belong to what the company defines as the Full Range Optics lenses design to provide spectacle independence in patients that undergoes cataract surgery.
