Definitions

  • the “aberration-free IOL” does not correspond to the physiological properties of the natural human lens and therefore can lead to sub-optimal results. This lens can be used for eyes after refractive surgery, eyes with keratoconus or with atypical corneal spherical aberration.
  • the IOL can be made of a material that has a varying refractive index so that a spherical aberration results equal to or approaching the spherical aberration of the human eye.
  • FIG. 5 shows another embodiment of the aspherical IOL according to the invention.
  • FIG. 6 shows the radial optical power and corresponding zones for different IOLs
  • the Liou-Brennan eye as shown in FIG. 1 , represents the ocular anatomy very closely and preserves the optical properties and aberration characteristics of the human eye.
  • This eye model includes an aspherical cornea with anterior surface 1 . 1 and posterior surface 1 . 2 as well as an aspherical gradient-index lens model.
  • the anterior chamber is identified by reference numeral 8 , the vitreous body by 7 and the retina by 4 .
  • the model takes into account that, for the majority of the population, the visual axis 5 is tilted by 5° with respect to the axis of symmetry 9 of the eye in order to focus in the macular region 4 . 1 .
  • Rotationally symmetric polynomial aspheric surfaces are described by a polynomial expansion of the deviation from a spherical surface (or an aspheric surface described by a conic section).
  • the even aspherical surface model uses only the even powers of the radial coordinate to describe the asphericity.
  • the model uses the base radius of curvature and the conic constant.
  • the required range of base optical powers from 5D to 40D can be easily calculated by setting the localized target power operands of the merit function to the desired power values and minimizing the remaining errors accordingly.
  • FIG. 6 shows the radial refractive power profile of the modified IOL in comparison with other lens designs of the prior art.
  • the enhanced capabilities result from the particular characteristic of the radial refractive power distribution as a function of the radius normal to the optical axis. All IOLs start at their paraxial refractive power of 22D (22 diopters) at a radius of 0 mm.
  • the refractive power of the symmetric biconvex lens B&L LI61 increases continuously toward the lens edge. This indicates a significant amount of SA that exceeds the naturally given amount.
  • the optical power of the lens TECNIS Z9000 decreases greatly with increasing radius to provide a negative SA that compensates for the corneal contribution.
  • the drawback of this approach results from the high sensitivity of this design with regard to a decentration of the IOL.
  • the third example of the prior art is the “aberration free IOL” B&L SofPort A0.
  • This lens assumes independence of the optical performance with respect to decentration. This is accomplished by keeping the radial power at a value equal to the paraxial power for all radii. In this case the lens is free from an inherent SA. If this condition is satisfied, a decentration does not cause coma errors which compromise image quality dramatically in the presence of decentration.
  • this lens design has a significant disadvantage. The natural compensation effect of the human crystalline lens is completely ignored. The image quality at the retina is therefore suboptimal for the patient since the full amount of the corneal SA affects the visual acuity in a negative way.
  • FIG. 7 shows that the new lens design ensures a diffraction limited performance up to a pupil size of 4 mm and equals the performance (Strehl ratio as a function of pupil diameter) of the natural crystalline lens for the entire pupil range.
