Letter imaging by diffractive, bifocal intraocular lenses: a computer study

Letter imaging of ideal-model diffractive, bifocal intraocular lenses is computer simulated. How the image is influenced by letter size, pupil diameter, and pupil displacement is studied. We find that the image quality is good as long as the letter sizes are not of the same order of magnitude as the...

Summary:Letter imaging of ideal-model diffractive, bifocal intraocular lenses is computer simulated. How the image is influenced by letter size, pupil diameter, and pupil displacement is studied. We find that the image quality is good as long as the letter sizes are not of the same order of magnitude as the unfocused background. If the sizes are comparable, considerable image degradation occurs.
