Due to the high incidence of post-operative IOL misalignment, our results provide evidence of the importance of considering personalized angle $\kappa$ before cataract surgery for patients. With angle $\kappa$, the impact of IOL misalignment on visual quality was associated with the orientation of decentration and tilt, indicating that the coma compensation also took effect in pseudophakic eyes. Coma aberration played an unexpectedly important role in the optical performance. We found that an aspheric balanced curve optic surface maintained better optical performance via inducing less coma aberration.
IOL ZEMAX FILE SOFTWARE
ZEMAX software has been used to imitate the optical performance of pseudophakic eyes with different IOL surface designs at different orientations of IOL misalignment (decentration of 0.4 mm and tilt of 7°, and with the existence of 0.5 mm angle $\kappa$). Intraocular lens (IOL) misalignment and angle $\kappa$ have had significant negative impact on post-operative quality of vision. Zemax (Zemax Development Corp., San Diego, U.S.A.) non-sequential ray tracing analysis has become the present standard for computerized test-ing of the optical pathways of light through IOLs. Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored.Use a comma to separate multiple people: J Smith, RL Jones, Macarthur the Zemax optical des i gn program (Zemax, LLC, Washin gton, USA) to study the sphe rical shif t of the IOL / 17 tilt by means of through-focus re sponse (TFR) 18 and v isual acuity (V A.Use these formats for best results: Smith or J Smith.For best results, use the separate Authors field to search for author names.Use quotation marks " " around specific phrases where you want the entire phrase only.

The file examplefarfieldsforzemaxexport.ldf contains the far-field results for wavelengths 625nm (Red), 525nm (Green), and 420nm (Blue), which can be obtained by running the simulation files provided in the example. Separate search groups with parentheses and Booleans.The details of design and optimization are given, and the optical performance of the pseudophakic eye with the designed IOLs is assessed with the spot diagram and the visual acuity. Keep it simple - don't use too many different parameters. Eye model is firstly used to design and assess the performance of intraocular lenses (IOL) with extended depth of focus (DOF), including aspherical IOL, refractive multifocal IOL and diffractive multifocal IOL.
