Optical bench performance of a novel trifocal intraocular lens compared with a multifocal intraocular lens
PURPOSE The purpose of this study is to compare the optical characteristics of the novel PanOptix presbyopia-correcting trifocal intraocular lens (IOL) and the multifocal ReSTOR +3.0 D IOL, through in vitro bench investigations. METHODS The optical characteristics of AcrySof(®) IQ PanOptix™ (PanOptix) and AcrySof(®) IQ ReSTOR +3.0 D (ReSTOR +3.0 D) IOLs were evaluated by through-focus Badal i...
متن کاملIntraocular lens implant.
In the past, patients with uniocular cataracts who underwent cataract extraction were not able to tolerate aphakic spectacles due to 30% magnification of visual images thus giving rise to diplopia. The other alternative was to use contact lens which needed motivation. Some could not tolerate contact lens and its magnification of 5% to 7%. These failures eventually led to the idea of intraocular...
متن کاملAccuracy of Intraocular Lens Power Calculation Formulas for Highly Myopic Eyes.
Purpose. To evaluate and compare the accuracy of different intraocular lens (IOL) power calculation formulas for eyes with an axial length (AL) greater than 26.00 mm. Methods. This study reviewed 407 eyes of 219 patients with AL longer than 26.0 mm. The refractive prediction errors of IOL power calculation formulas (SRK/T, Haigis, Holladay, Hoffer Q, and Barrett Universal II) using User Group f...
متن کاملIntraocular lens calculation accuracy limits in normal eyes.
PURPOSE To quantify the current accuracy limits, analyze the residual errors, and propose the next steps for prediction accuracy improvements. SETTING Eye hospitals in Germany, Denmark, and Austria. METHOD Numerical ray tracing using manufacturer's intraocular lens (IOL) data (vertex radii, central thickness, refractive index) was used for all calculations. Postoperative lens position was p...
متن کاملMyopic Shift after Implantation of a Novel Diffractive Trifocal Intraocular Lens in Korean Eyes
PURPOSE To evaluate the clinical outcomes of cataract surgery using novel diffractive trifocal intraocular lenses (IOLs) in Koreans. METHODS This was a retrospective, consecutive, interventional study of cataract surgery using POD FineVision IOL implantation. Complete ophthalmologic examinations were performed preoperatively and postoperatively. Defocus curves were assessed over a range of +1...
