trifocal IOL

Considerations when implanting mIOLs in amblyopia with strabismus patientsMultifocal IOLs (mIOLs) can provide excellent uncorrected visual acuity at all distances. However, photic phenomena such as glare and halos are inherent to the design of these lenses and make preoperative patient councelling, careful case selection, and individualised weighing of benefits and side-effects important.
Study finds advantages using trifocal IOL to correct presbyopiaA 4-year study following trifocal IOL implantation (AT LISA tri 839MP, Carl Zeiss Meditec) found that the lens provided good distance, near, and intermediate visual acuity. The lens also improved patient quality of vision with better diffraction and less reduction in contrast sensitivity.
Complicated case underscores need for care, preparationA case of cataract surgery with planned presbyopia-correcting IOL implantation– complicated by posterior capsule rupture and a postoperative refractive surprise– reinforced important lessons and provided a new revelation to one experienced surgeon.
Toric trifocal IOL brings expanded range of functional vision to larger patient population
Toric trifocal IOL brings expanded range of functional vision to larger patient populationTrifocal 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.
Achieving patient satisfaction with multifocal IOLsMultifocal 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.
Novel trifocal IOL extends range of visionA 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.
Trifocal lens receives European CE markAlcon has received European CE mark for a trifocal IOL (AcrySof IQ PanOptix) designed for patients who are undergoing cataract surgery and want to address their near, intermediate, and distance vision needs with one lens.
The multifocal IOL evolution
The multifocal IOL evolutionMultifocal 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.
Examining visual outcomes of bilateral trifocal IOLA new trifocal diffractive IOL (FineVision trifocal IOL, PhysIOL), implanted bilaterally, achieved a full range of adequate vision, satisfactory contrast sensitivity, and a lack of significant adverse photic phenomena, according to Spanish researchers reporting in BMC Ophthalmology.
New double C-loop haptics improve stability for novel trifocal IOL technologyA new trifocal IOL with double C-loop haptics (Micro F FineVision, PhysIOL) delivers excellent outcomes based on the benefits of its optic features and haptics.
