| Abstract Nr. | 234 |
| But | The healthy middle-aged human lens transmits EM radiation in a specific manner. Its physiological optical transmission characteristic is different from that of most "standard" IOLs presently in use, which contain a UV blocker and possibly also a blue blocker. Implantation of an IOL with non-physiological transmission characteristic may result in photophobia, distorted color perception and increased chromatic aberration. The purpose is the evaluation of visual function and patient satisfaction after implantation of an IOL with a physiological transmission characteristic ("physiological" IOL), and compare it with the same evaluation after implantation of a "standard" IOL with or without a blue blocker. |
| Méthodes | Patients with an age-related cataract in both eyes, without another ocular disorder. Phaco was performed on one eye, and a "standard" IOL was implanted. The patient was given the option of a "physiological" IOL in the other eye. (It was known from a previous non-invasive study that a situation with a "standard" IOL in one eye and a "physiological" IOL in the other is not disadvantageous as compared to a "standard" IOL in both eyes.) A cohort of fifty patients, with a "standard" IOL in one and a "physiological" IOL in the other eye, was evaluated for visual function (including visual acuity, color perception and contrast sensitivity) and for visual discomfort (including photophobia). During evaluation, one eye and then the other were occluded in random sequence. |
| Résultats | Implantation of a "physiological" IOL was found to result in better visual function and more visual comfort, regardless of the presence or absence of a blue blocker in the "standard" IOL. |
| Conclusion | A "physiological" IOL is superior to a "standard" IOL. |
