עדשות חניתהHanita Lenses7 of 21In order to provide a quantitative demonstration of the improvement in sensitivity of thecontrast of the SeeLens AF in comparison with the standard equal convex spherical SeeLens awide range of optical simulations was performed using the ZEEMAX software which is apowerful and accurate tool in optical field.Figure 5:SeeLens AF 5mm pupil MTF Hanita Lenses advanced optics.ZEEMAX simulation vs. spatial frequency 0-100 [Cyc/mm] .The black line defines the ideal diffraction limit of the MTF.The blue line defines the lens actual simulated performance.Figure 6:Equi-convex conventional 5mm pupil MTF spherical optics.ZEEMAX simulation MTF vs. spatial frequency 0-120[Cyc/mm].The black line defines the ideal diffraction limit of the MTF.The blue line defines the lens actual simulated performance.Figures 5 and 6 demonstrate the simulated MTF result of the lens in a dilated pupil of 5 mmwhich corresponds to the normal mydrated pupil. The SeeLens superiority isstraightforwardly noticed as the MTF decreases much faster as the spatial frequency rises inthe standard lens with respect to the SeeLens AF which remains very close to the MTFrefraction physical limit.e. Influence of tilt and decentrationThe SeeLens AF is based upon the mechanical design of SeeLens equi-convex spherical lens.The SeeLens design was proven to have good stability and good resistance to tilt andcentration as well. Moreover, the SeeLens AF Optical design was demonstrated by theZEEMAX to have good resilience in terms of tilt and decentration as presented in the attachedgraph.Hanita Lenses Intraocular & Contact Lenseעדשות חניתהעדשות מגע ועדשות השתלה תוך-עינית•קיבוץ חניתה • 88222 www.hanitalenses.com Kibbutz Hanita 22885 Israel • Tel. 972-4-9950 700• Fax: 972-4-9950 755 •
עדשות חניתהHanita Lenses8 of 21Figure 7: The influence of the degree of Tilt on the resultant MTFFigure 8: The influence of the degree of Tilt on the resultant MTFThe Hanita Lenses intraocular lens hydrophilic material has been in use at Hanita Lenses formore than 7 years and effectively verified its outstanding long-term behaviour in the marketin terms of biocompatibility, transparency and stability of the visual function and centration.A foldable and highly adaptable implant for all bag conformations, the SeeLens AF displaysoutstanding tensile strength for maximum resistance during insertion, and offer controlledunfolding for rapid visual recovery.f. Micro incision cataract surgeryAnother advantage, which is derived from the SeeLens AF design, is its Micro IncisionCataract Surgical (MICS) property. The SeeLens AF can be injected through a 2.0 mmincision. This property makes the SeeLens AF surgical procedure almost free of inducedsurgical cylinder to the eye.3. Surgical ProcedureThe study Surgery Procedure: cataract extraction by ECCE Phacoemolsification. Operationwas performed according to the routine surgery technique of the investigative sites.The surgical procedure was conducted according to protocol.Hanita Lenses Intraocular & Contact Lenseעדשות חניתהעדשות מגע ועדשות השתלה תוך-עינית•קיבוץ חניתה • 88222 www.hanitalenses.com Kibbutz Hanita 22885 Israel • Tel. 972-4-9950 700• Fax: 972-4-9950 755 •
