New Concept ofTruly

ACCOMMODATING IOLInventor: 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.
