The WhiteStar Signature Pro (J&J Vision) offers a diverse range of novel technologies that blend together to make cataract surgery easier, safer, and more efficient, according to Steven H. Dewey, MD.

Residual astigmatism is not uncommon after toric IOL implantation. Depending on its cause and magnitude, lens reorientation may be a good solution.
Cataract surgery in eyes undergoing simultaneous endothelial keratoplasty requires several modifications in techniques.
Achieving satisfaction for patients interested in a multifocal IOL begins with comprehensive preoperative screening and evaluation.
A novel toric IOL features an aberration-free, transitional conic anterior optic surface shows pupil independence and improved tolerance to misalignment in bench testing and excellent clinical outcomes.
Trifocal IOLs can provide good uncorrected vision at near, intermediate, and far. Outcomes in a series of 30 patients show that a toric version of a trifocal IOL (AT Lisa tri 939MP, Carl Zeiss Meditec) delivers those benefits for patients with > 1 D of corneal astigmatism.
Accommodating-disaccommodating IOLs are being developed that mimic the movement of the young crystalline lens through the use of “Zonular Capture Haptics” technology.
Multifocal IOLs offer the potential to reduce spectacle dependence, but outcomes vary depending on optical design. Optimizing success and satisfaction depends on careful patient selection, thorough counseling, and good surgical technique.
A new non-apodized diffractive trifocal IOL allows 88% energy utilization and sends energy to near (40 cm), a preferred intermediate distance (60 cm), and far (infinity). Early results for visual acuity, contrast sensitivity, and photopic symptoms are encouraging.
Multifocal IOLs with a trifocal diffractive optic design are available outside of the United States. They provide good visual acuity for distance, intermediate, and near and appear to provide slightly better intermediate vision than bifocal diffractive multifocal IOLs.
