Anterior Chamber Intraocular Lens

When a cataract (cloudy lens) is removed, an intraocular lens (IOL) implant is usually placed inside the eye to focus incoming light. In current cataract surgical technique, the IOL generally is inserted behind the iris. Occasionally, certain cases necessitate IOL placement in front of the iris or in the anterior chamber. Anterior chamber IOLs were used more in the earlier years of implants but are still seen.

One of the most important concerns with an anterior chamber IOL is how it is held in place. You will be able to see posts, clips, or haptics (legs). Posts or clips should firmly anchor the IOL into the pupil. (An iris-fixed IOL that has posts or clips should not be dilated. The implant is held in place by the pupil; dilation of the eye may cause dislocation of the IOL.) Haptics should not dig into the cornea or angle. The optic might be round or rectangular. Regardless of shape, it should be even with the iris plane. The lens should also be centered over the pupil opening. Documentation (if AC IOL is present): AC IOL clear and in place
