Multifocal Intraocular Lenses: AT LISA Tri Toric 939 M/MP
The presence of more than 1.00 D of astigmatism in eyes implanted with diffractive multifocal IOLs has been shown to compromise corrected distance and distance-corrected near visual acuities. This was the reason that led to the development of multifocal toric IOLs. These implants have been demonstrated to provide good visual outcomes at different distances (Mojzis et al. J Cataract Refract Surg 40:60–69, 2014; Alio et al. J Refract Surg 29:756–761, 2013; Hayashi et al. J Cataract Refract Surg 36:1323–1329, 2010; Knorz et al. J Refract Surg 29:762–767, 2013, Bellucci et al. J Cataract Refract Surg 39:1507–1518, 2013; Mojzis et al. Graefes Arch Clin Exp Ophthalmol 251:341–348, 2013; Mojzis et al. J Refract Surg 27:648–657, 2011; Mojzis et al. J Cataract Refract Surg. 2015 Dec;41(12):2695-706). Recently, trifocal toric IOLs have been developed as an option to compensate for different levels of preexisting corneal astigmatism after cataract surgery and to simultaneously provide complete restoration of visual function.
