Abstract Details

Purpose:

A Negative dysphotopsia (ND) is one of the difficult complications after safe cataract surgeries.  We have experienced a case having negative dysphotopsia and a second intraocular lens (IOL) exchange and repositioning are effective.

Setting:

Department of Ophthalmology, Dokkyo Medical University, Tochigi, Japan.

Methods:

A 68 years-old-man was consulted to our department for surgery with both cataract and left epiretinal membrane. For Left eye, phacoemulcification:PEA+IOL (PU6A) implantation and vitrectomy were performed. For right eye PEA and IOL (PCB00V) implantation were performed. The corrected visual acuity after surgery was good with right eye of 20/20 and left eye of 14/20. However, patient complained about shadows which could be seen on the nose side after surgery for only right eye. Although no improvement about the symptom, we performed bag-to-bag IOL exchange (NX-70). However, the symptom was remained. So we performed the right IOL position correctioning (reverse-optic-capture).

Results:

The ND was improved after the third surgery (reverse optic capture) using a 7 mm IOL. The IOL-iris distances of 1st, 2nd and 3rd are 0.813, 0.748 and 0.491 respectively.

Conclusions:

We experienced a case which symptoms improved by reverse optic capture of a 7mm IOL with a large optical diameter for advance ND. The IOL size and IOL-iris distance may related with occurrence of ND.
