New Concept ofTruly ACCOMMODATING IOL Inventor: Dr. Elie KHOURI Ophthalmologist Invention: under patent pending
Being the inventor, I have full financial interest IF the idea is adopted by a company • So far there is NONE. I am still looking.
Multifocal IOLs • The Multifocal IOLs, by splitting the incoming light to the eye causing a double visual image,they decrease enormously the CONTRAST sensitivity, and they cause a lot of GLARE and HALOS. Patient education is mandatory • These lenses should be very well CENTERED. • They should NOT be implanted in patients with MACULAR DEGENERATION. • Many of them have been explanted.
Tranlational IOLs • These “accommodating” IOLs suffer from insufficient advancement, therefore they DO NOT provide adequate near vision, especially after capsular fibrosis…
Dual-Optics IOLs • The Dual-Optics IOLs rely on a spring-action advancement of the front IOL due to the zonular relaxation during accommodation(Helmoltz theory). We don’t know what will happen to this spring action after a while and especially after the capsular fibrosis. • They have not been FDA approved .
NuLens • This IOL can accommodate over 10D by increasing its anterior curvature. • The idea is very good. • The problem is in its design: it is implanted in the CILIARY SULCUS, through “9mm” “LIMBAL INCISION”…THIS,WE DO NOT WANT.
Pseudophakic Presbyopia • All this to say that, so far, pseudophakic presbyopia has NOT been SOLVED yet. • All the presbyopia correcting IOLs have dissatisfactory drawbacks. • So, we need a new concept for a NEW DESIGN of a TRULY ACCOMMODATING IOL.
My Concept • Presbyopia is caused by the crystallin lens • The ciliary muscle continues to contract at all ages. • Dr.Coleman demonstrated that during accommodation, therefore during ciliary muscle contraction, there is an increase of the vitreous pressure enough to push the lens forward. • Then forgetting about the zonular relaxation during accommodation (Helmoltz theory), I thought only about the vitreous pressure to create a soft lens to be implanted through a small incision, and, due to the vitreous pressure pushing it forward, this IOL will bulge its anterior curvature, thus creating accommodation as much as we want. • The more ciliary muscle contraction, the more posterior IOL pressure, the more increasing curvature of the anterior leaflet of the IOL, the more ACCOMMODATION. • This IOL can also be injectable through a very small incision to fill the whole capsular bag and be inflated inside the bag.
