Extended Range Of Vision In Unusual Cases

To present the results of a novel intraocular lens (IOL) in cataract patients who are unsuitable for conventional presbyopia corrective IOL implantation due to a history of refractive surgery or ocular problems.

Private Hospital, Ophthalmology Clinic, İstanbul, Turkey

Twenty patients presented for cataract surgery at the same private clinic will be reported on. In each case, same surgeon (BB) implanted the patients with a non-diffractive, extended depth of focus IOL due to the presence of an ocular disease or history of corneal refractive surgery. Main outcome measures were post operative refraction, visual acuity and satisfaction evaluated by Visual Function Index (VF-14) questionnaire. The IOL has a central optic that has induced positive spherical aberrations, which are intended to provide a range of vision.

10 cases had findings of age related macular degeneration. 2 of those cases had glaucoma. 5 cases had diabetic retinopathy. 2 cases had ambliopia and 3 cases had history of refractive surgery.  Visual acuity and refraction of the patients as well as the results of VF-14 questionnaire in each group will be reported. 

It is well documented that patients with pre-existing ocular disease, as well as those who have undergone corneal refractive surgery are not good candidates for trifocal IOLs. This small case series indicates that for patients who expect to have a range of vision following cataract surgery, a non-diffractive EDOF IOL may be a good alternative.
