WHAT IS AN INTRAOCULAR LENS?
An intraocular lens (IOL) is an artificial lens that is implanted in the eye during routine cataract surgery or refractive lens exchange to replace the natural cloudy lens. The IOL is designed to improve vision by focusing light onto the retina. There are different types of IOLs available, including single vision “monofocal” lenses, presbyopia correcting “multifocal” lenses, extended depth of focus lenses, and astigmatism correcting toric lenses. In rare circumstances, an IOL can become decentered or dislocated causing in significant vision impairment for the patient.

SIGNS & SYMPTOMS OF AN IOL COMPLICATION
- Double vision – seeing two or more of one object
- Suboptimal vision – blurry or hazy vision making it difficult to focus clearly
- Glares/Halos – trouble seeing in low light and low contrast settings
- Light sensitivity
- Redness and Pain – a sign of inflammation inside the eye
- Elevated eye pressure
IOL dislocation is a rare complication. Risk factors include:
I. Early Dislocation
- Complication(s) during cataract surgery – capsular tear, vitrectomy, zonular weakness
- Trauma (i.e., sustaining a fall or blunt trauma to face)
II. Late Dislocation:
- High myopia
- Genetic predispositions: Marfan’s, Retinitis Pigmentosa, Weill Marchesani, Homocystinuria
- Pseudoexfoliation syndrome
- Dead Capsular Bag Syndrome
Treatment options depend on the severity of the condition and is determined on an individual basis
I. Non-Surgical Options
In select asymptomatic cases, a dislocated IOL may not need to be repositioned. The patient can be safely monitored for any changes in his or her vision. Glasses may be prescribed to improve vision. In mild cases, eye drops may be prescribed to alleviate pain and inflammation. A pupil-constricting eye drop may be used to ameliorate double vision, glares, or halos.
II. Surgical Options
In more severe cases, surgery may be recommended to either remove or reposition the existing IOL to improve vision. Many safe outpatient micro-surgical techniques exist. These include:
- IOL Iris Fixation
- IOL Capsular Complex Lasso
- IOL exchanged for an anterior chamber IOL
- Yamane Sutureless IOL scleral fixation – the newest micro-surgical technique
