Parameters of the IOLs used in the study.
Fig 1.
The on -axis MTF of the designed IOLs as a function of misalignment (left column) and tilt (right column) with a 3.00 mm pupil diameter and 100 cycles per degree with different corneas.
The tangential MTF (continuous line) and the sagittal MTF (dashed line) are shown for each cornea: A) Navarro’s eye model cornea, B) Myopic cornea, C) Hyperopic cornea.
Table 4.
Minimum values of misalignment and tilt for which the average of tangential and sagittal MTF is below 0.43 (for an object of 100 cycles/mm and a 3.00 mm pupil diameter) at every analysed cornea.
Fig 2.
RMS defocus () values of the designed IOLs for misalignment (left column) and tilt (right column) with each different cornea: A) Normal, B) Myopic, C) Hyperopic.
Fig 3.
RMS astigmatism ( and
) values of the designed IOLs for misalignment (left column) and tilt (right column) with each different cornea: A) Normal, B) Myopic, C) Hyperopic.
Fig 4.
RMS coma ( and
) values of the designed IOLs for misalignment (left column) and tilt (right column) with each different cornea: A) Normal, B) Myopic, C) Hyperopic.
Fig 5.
RMS spherical aberration () values of the designed IOLs for misalignment (left column) and tilt (right column) with each different cornea: A) Normal, B) Myopic, C) Hyperopic.
Fig 6.
MTF average values (average between tangential and sagittal) for each IOL design (Lens A, Lens B and Lens C) with each cornea, in the worst-case scenario: 5 degrees of tilt and 1 mm misalignment. Corneas are represented in rows: A) Normal, B) Myopic, C) Hyperopic.
Fig 7.
Simulation of the retinal images of a 5’ angular size optotype (VA of 0.00 LogMar scale) generated by each designed IOL (in columns: Lens A, Lens B and Lens C) with every cornea (in rows: A) Normal, B) Myopic, C) Hyperopic) at the worst-case scenario (a combination of 5 degrees of tilt and 1 mm misalignment of the IOL).
