EW REFRACTIVE 44 May 2017 logMAR –0.04 and trifocals with logMAR –0.02. EDOF patients scored highest for binocular uncorrected intermediate visual acuity, measured at 80 cm, achieving a median visual acuity of logMAR –0.08, followed by trifocals with logMAR –0.04 and bifocals with logMAR 0.01. Binoc- ular uncorrected near visual acuity, measured at 40 cm, showed best outcomes in the bifocal group that achieved a median logMAR –0.03, followed by the trifocal group with logMAR 0.07, and the EDOF group with logMAR 0.14. In the bifocal group, median binocular distance corrected near visual acuity was highest at logMAR –0.07 compared to the trifocal group with logMAR –0.01 and the EDOF group at logMAR 0.24. The out- comes observed for median binocu- lar distance corrected intermediate visual acuity were highest in the trifocal group at logMAR –0.13, EDOF with logMAR –0.06, and the bifocal group scoring worst with logMAR 0.07. The researchers noted similar preferences for intermediate reading distances of about 65 cm, among the three groups, with similar reading acuities in the bifocal and trifocal IOL groups. The smallest readable letter size without correction was best in the bifocal group for near, and similar in the bifocal and trifo- cal groups for intermediate vision. The lowest incidence of halos was observed in the bifocal and trifocal groups, and it was higher in the EDOF group. However, there was no statistical significance (P>.05). Night glare was worst among trifocal patients, followed by bifocals and lowest in EDOF. The incidence of day glare, painful/ burning eyes, double images, vision problems under bright light conditions, vision problems under normal light conditions were all low. Bifocal and trifocals had similar outcomes under low light conditions. Nearly 20% of the FineVision questionnaire respondents respond- ed with "No" to such questions as, "satisfied with the result of surgery," "would have the surgery with the same IOL again," or "would recom- mend the IOL." The highest satisfac- tion rate for the same questions was from the Symfony group, showing 95% patient satisfaction and with minute and reading distance were important for the calculation of reading acuity using the reading desk. The postoperative examina- tions were conducted no sooner than 3 months postoperatively to guarantee stable visual acuity. Visual acuity was expressed in logMAR, ac- cording to which a value of logMAR –0.10 corresponds to 20/16, or a decimal value of 1.25; logMAR 0.00 corresponds to 20/20, or a decimal value of 1.00; and logMAR +0.10 corresponds to 20/25, or a decimal value of 0.80. The investigators implanted the FineVision, a 1-piece aspheric trifocal IOL, in 21 eyes of 11 pa- tients, whose median age was 66 years. They implanted the AcrySof IQ ReSTOR (SN6AD1), a 1-piece sym- metric biconvex, anterior aspheric, bifocal IOL with a low/moderate near addition, in 40 eyes of 20 patients, with a median age of 55.5 years. Finally, the Symfony (ZXR00 and ZXT), a 1-piece, anterior aspher- ic, extended-depth of focus IOL, was implanted in 31 eyes of 16 patients with a median age of 70 years. Standout results The binocular uncorrected distance visual acuity (UDVA) outcomes were best in bifocal patients, achieving a median visual acuity of logMAR of –0.06, followed by EDOF with compared the FineVision trifocal IOL (PhysIOL, Liege, Belgium), the AcrySof IQ ReSTOR SN6AD1 bifocal IOL (Alcon, Fort Worth, Texas), and the Symfony EDOF IOL (formerly Abbott Medical Optics, now John- son & Johnson Vision, Santa Ana, California), for distance, intermedi- ate, and near visual performances, as well as the patients' quality of life. The investigation was performed at the International Vision Correc- tion Centre (IVCRC), Department of Ophthalmology, University Hospital Heidelberg, Heidelberg, Germany, by Mary Attia, MD, under the super- vision of Gerd Auffarth, MD, PhD. The surgeries were performed as well as technical support provided by the co-authors. The team divided 92 eyes into three groups, with patients in each group receiving a bifocal, trifocal, or EDOF IOL. Dr. Attia presented the outcomes at a poster discussion forum during the 2016 American Academy of Ophthalmol- ogy annual meeting in Chicago. Primary outcome measures included postoperative uncorrected and corrected distance, intermediate and near visual acuity, preferred near and intermediate reading distance using the Salzburg Reading Desk with and without distance correc- tion, and a patient questionnaire. Both the letter size of the smallest readable sentence at ≥80 words per A new comparative study shows narrow differences between trifocal, bifocal, and extended depth-of- focus IOLs for near, intermediate, and distance visual acuities I ntermediate vision from a dis- tance of 50–80 cm has gained in importance in today's world largely due to heightened computer and smartphone use. Subsequently, intraocular lenses (IOLs) that allow you to focus on ob- jects and read from an intermediate distance, such as trifocals, bifocals with a low/moderate near addition, and extended depth-of-focus (EDOF) IOLs, have grown in relevance and are in great demand. At the same time, patients have come to expect spectacle independence for near and distance vision. Three viable presbyopic options Data from a recent comparative study suggested that all three IOL types provided excellent vision and that IOL choice relied mostly on how well a lens' visual character- istics fit the individual's lifestyle. The study set out to determine differences between the lenses, both objectively and subjectively, and Intraocular lenses for correction of presbyopia measure up by Stefanie Petrou Binder, MD, EyeWorld Contributing Writer Presentation spotlight Salzburg Reading Desk: A vital part of the study
