Personalized intraocular lenses to optimize the treatment result in lens surgery
Background
In the treatment of cataract, the clouded natural lens of the eye is replaced with an artificial lens/intraocular lens (IOL). Such IOLs are also used in so-called refractive lens surgeries to treat high ametropia, in which the natural lens is replaced by an artificial lens with a corrective refractive effect or an additional artificial lens is placed in front of the natural lens.
In the early years of cataract surgery, spherical IOLs were predominantly used, which increased the spherical aberration of the cornea. With aspherical IOLs, the spherical aberration could either be left unaffected (aberration-neutral IOL) or reduced by a certain amount (aberration-correcting IOL). However, so far only standardized IOLs have been used that correct the spherical aberration of a statistical normal eye.
After the implantation of such aspherical IOLs, Prof. Thomas Neuhann, MVZ Prof. Neuhann, observed individual patients who, in addition to excellent distance vision, also showed unexpectedly good vision in the intermediate and near distance with very good contrast vision at the same time. This observation is attributed to optimal correction of the spherical aberration of the cornea.
In the present project, the individual spherical aberration of the cornea of each eye is now to be completely corrected with an individually produced IOL in order to achieve the positive effect of an IOL with a constant asphere that has already been observed in isolated cases to restore the best possible vision in far, intermediate and near distance without restriction in contrast vision in all patients.
