Clinical evaluation of a multifocal aspheric diffractive intraocular lens. Schmickler S, Bautista CP, Goes F, Shah S, Wolffsohn JS.
Evaluation of the aspheric tecnis multifocal intraocular lens: one-year results from the first cohort of the Food and Drug Administration clinical trial. Intraocular lens multifocality combined with the compensation for corneal spherical aberration: a new concept of presbyopia-correcting intraocular lens. Visual performance of Tecnis ZM900 diffractive multifocal IOL after 2500 implants: a 3-year followup. Tecnis multifocal one-piece IOL intermediate visual acuity mesopic visual acuity near visual acuity photopic visual acuity.Īkaishi L, Vaz R, Vilella G, Garcez RC, Tzelikis PF. High levels of spectacle independence with low levels of photic phenomenon were achieved, resulting in excellent patient satisfaction. Tecnis multifocal one-piece intraocular lenses provide good distance, intermediate, and near visual acuity under photopic as well as mesopic lighting conditions. A total of 87.5% of patients reported no glare and 68.8% of patients reported no halos around lights at night. All patients were satisfied with their overall vision without using glasses and/or contact lenses when compared with before surgery. Under photopic and mesopic conditions, 93.8% and 62.5% of patients, respectively, had binocular uncorrected intermediate visual acuity of 20/40 or better, and 62.5% and 31.3% of patients had binocular uncorrected near visual acuity of 20/20 or better. All patients also completed a subjective questionnaire.Īt a mean follow-up of 9.5☓.9 months, distance, near, and intermediate visual acuity improved significantly from preoperative acuity. Monocular and binocular uncorrected and distance-corrected visual acuities were measured at distance (20 ft), intermediate (70-80 cm), and near (35-40 cm) under photopic (85 cd/m(2)) and mesopic (3 cd/m(2)) lighting conditions and were compared using the paired t-test. In this retrospective-prospective study, 16 patients with a mean age of 66.2☙.2 years (range: 50-81 years) who had undergone bilateral phacoemulsification surgery with implantation of a Tecnis multifocal one-piece intraocular lens (ZMB00) were evaluated. The aim of the study is to evaluate the visual acuity and patient satisfaction at varied distances under photopic and mesopic lighting conditions in patients bilaterally implanted with aspheric diffractive multifocal one-piece intraocular lenses.
