Trifocal toric lens

E Hemkeppler, M Böhm, T Kohnen
A 52-year-old highly myopic female patient was implanted with a multifocal, diffractive, toric intraocular lens because of the wish to be independent of eyeglasses. Despite high-quality, extensive preoperative examinations, a hyperopic refractive error remained postoperatively, which led to the patient's dissatisfaction. This error was treated with Laser-in-situ-Keratomileusis (LASIK). After corneal LASIK treatment and implantation of a diffractive toric multifocal intraocular lens the patient showed a good postoperative visual result without optical phenomena...

PURPOSE: To compare the rotational stability, total misalignment, and visual and refractive outcomes achieved with a trifocal toric versus a monofocal toric intraocular lens (IOL). METHODS: In this prospective, interventional case series, eyes of patients consecutively scheduled for cataract surgery who had clinically relevant astigmatism were implanted with a FineVision Pod FT trifocal toric IOL or an Ankoris monofocal toric IOL (both PhysIOL SA, Liège, Belgium)...

We report the case of an emmetropic 32-year-old female with decreased uncorrected visual acuity and diplopia due to intermittent episodes of spasm of the near reflex. Neurologic, general, and ophthalmic examination could not find an organic cause. Attempts at spontaneous recovery, psychogenic therapy, and cycloplegic therapy were unsuccessful and the symptoms persisted for almost 5 years, leading to psychogenic distress. Final treatment with refractive lens exchange and implantation of a toric trifocal intraocular lens resolved the spasm of the near reflex, resulting in an uncorrected distance and near visual acuity of 20/20...

PURPOSE: To determine whether use of a capsular tension ring (CTR) can increase refractive stability in patients with implantation of two different trifocal intraocular lenses (IOLs). METHODS: A prospective, consecutive series of eyes underwent refractive lens exchange with implantation of two different trifocal IOL designs: FineVision Micro F (non-toric) and FineVision POD FT (toric) (PhysIOL, Liege, Belgium). Power calculation was determined using the Haigis formula...

A young patient underwent phacoemulsification with endocapsular implantation of trifocal toric lens in both eyes (AT LISA tri toric 939 MP, Carl-Zeiss, Germany). One-week postsurgery, he developed capsular block syndrome (CBS) in both eyes. There was deterioration of uncorrected visual acuity at 1-week postsurgery, with a myopic shift of 2.5 diopters (D) in the right eye and 2.0 D in the left eye. The intraocular pressure was only elevated in the left eye. Neodymium: yttrium-aluminum-garnet laser posterior capsulotomy resolved the block successfully in both eyes...

In refractive surgery the removal of the natural lens followed by implantation of an artificial intraocular lens has been an established method to treat refractive errors. The term "clear lens exchange" separates this approach from cataract surgery, where a cloudy lens has to be removed. With regard to currently available intraocular lens technologies, there is a wide range to correct myopia, hyperopia as well as astigmatism. Trifocal or extended depth-of-focus lenses (EDOF) even with a toric component offer the patients a potential benefit to further address presbyopia, respectively...

PURPOSE: To evaluate the incidence of negative dysphotopsia after sequential cataract surgery. METHODS: Retrospective cohort study. The incidence of negative dysphotopsia was assessed by retrospective reviewing of medical records and interviews with patients between 2 and 4 months after sequential cataract surgery. Inclusion criteria were uncomplicated surgery, postoperative corrected distance visual acuity (CDVA) ≥20/25 Snellen and the absence of ocular comorbidity...

PURPOSE: To investigate refractive and visual acuity outcomes, patient satisfaction, and spectacle independence at 3 months of 2 diffractive (non-toric) trifocal intraocular lenses (IOLs) in a large series of patients. DESIGN: Multicenter, retrospective, nonrandomized clinical study. METHODS: Patients underwent lens phacoemulsification and were implanted bilaterally with a diffractive trifocal IOL: FineVision Micro F (PhysIOL SA, Liège, Belgium) or AT Lisa tri 839MP (Carl Zeiss AG, Jena, Germany)...

Purpose To evaluate and compare the visual performance of a trifocal and a trifocal-toric intraocular lens (IOL) based on the same diffractive platform. Methods Prospective non-randomized comparative study enrolling 142 eyes of 77 patients (age 40-73 years) undergoing uneventful phacoemulsification lens surgery. Two groups were differentiated according to the implanted IOL: trifocal group, 98 eyes (50 patients) implanted with the trifocal diffractive IOL AT LISA tri 839MP (Carl Zeiss Meditec), and trifocal-toric group, 44 eyes (27 patients) implanted with the trifocal-toric diffractive IOL AT LISA trifocal-toric 939MP (Carl Zeiss Meditec)...

PURPOSE: To evaluate the clinical results of toric trifocal diffractive intraocular lens in eyes with cataract and mild keratoconus. METHODS: Five keratoconus patients (10 eyes) that had bilateral AT LISA 939 implantation were selected and had followed in 3-time horizons of 1, 3, and 6 months. Patients were 46 to 65 years old age, corneal astigmatism of (2.00 D at 6.75 D) and cataract that all of them needed cataract surgery. The distance, intermediate and near visual acuities, defocus curve, ocular aberrations, contrast sensitivity, were measured as effectiveness criteria...

AIM: The aim of our study was to evaluate the outcome of cataract surgeries with implantation of intraocular trifocal toric lens, and to study the accuracy of astigmatism correction, lens rotational stability, and safety of the procedures. PATIENTS AND METHODS: Our study comprised 22 eyes of 16 patients who underwent unilateral or bilateral implantation of AT LISA tri toric 939MP, or its implantation in combination with AT LISA tri 839MP. Mean patient age was 58 ± 11 years (39 to 75 years)...

We present the case of a 56-year-old woman with moderate myopia and bilateral cataract who had cataract extraction and intraocular lens (IOL) implantation. Due to the patient's desire for spectacle independence, a trifocal IOL with toric correction for astigmatism was implanted. During the follow-up, it became obvious that the implanted IOL had rotated and tilted due to insufficient fixation in the large capsular bag of the myopic eye. An IOL explantation was therefore performed, and the original IOL was exchanged for a bifocal toric IOL with a larger overall diameter...

PURPOSE: The aim of this study was to compare a new diffractive trifocal toric lens with an apodized diffractive bifocal toric lens in terms of refractive and visual acuity (VA) outcomes, including low-contrast VA (LCVA), as well as the patient's visual function 3 months after implantation. PATIENTS AND METHODS: This is a randomized prospective study involving bilateral implantation of a trifocal toric or a bifocal toric lens. At 3 months postoperatively, the subject's vision was tested both uncorrected and with his/her best distance correction at: distance (4 m), intermediate (63 cm), and near (40 cm)...

PURPOSE: An evaluation of the visual and refractive results was undertaken one year after implantation of a trifocal diffractive toric intraocular lens (IOL) during cataract surgery. METHODS: In a prospective study patients with a calculated postoperative corneal astigmatism of ≥ 0.75 D received a diffractive trifocal toric IOL (AT LISA tri toric 939MP, Carl Zeiss Meditech, Jena, Germany) during cataract surgery. One year postoperatively the near, intermediate and distance visual acuity, corrected and uncorrected vision as well as refraction were evaluated...

New soft therapeutic contact lenses after glaucoma surgery provide good results, both in terms of tolerance and efficacy (60% pressure increase in a personal series of ten patients with the Trabeculens contact lens). Indicated for moderate immediate postoperative leakage, their use remains transitory and they should be removed as soon as intraocular pressure is (rapidly) corrected. After glaucoma surgery, wearing contact lenses can be discussed if there are no contraindications and 6-12 months after the intervention in a compliant patient...
