Replacing Intraocular Lens

Occasionally, during cataract surgery, the natural lens of the eye (which is the cataract), or parts (fragments) of the lens following cataract surgery, fall into the vitreous cavity. This may cause inflammation in the eye which can cause the normal pressure in the eye to rise to dangerous levels. The dislocated lens or cataract fragments can be removed by vitrectomy surgery.

Another problem that can occur during or after cataract surgery is the dislocation of the plastic lens implant, the intraocular lens (IOL). The IOL may become dislodged from its correct position or fall into the vitreous cavity. This can also occur following trauma to the eye. Vitreous surgery can be done to replace the plastic intraocular lens into its proper position. The vitreous is removed and then the lens is repositioned and sometimes sutured in order to keep it stable. In some eyes, the IOL may be removed entirely and replaced with a new IOL. The vision is usually good following this surgery unless complications such as retinal detachment or swelling of the macula occur.
