What does Dysphotopsia mean?

Positive dysphotopsia (PD) is a bright artifact of light, described as arcs, streaks, starbursts, rings, or halos occurring centrally or mid-peripherally. Negative dysphotopsia (ND) is the absence of light on a portion of the retina described as a dark, temporal arcing shadow.

Cataract surgery is irreversible. This is because the cloudy natural lens that results in a cataract is removed during surgery and cannot be placed back in.

How do you deal with negative Dysphotopsia?

Surgical strategies to address negative dysphotopsia included bag-to-bag IOL exchange, reducing posterior chamber depth with iris suture fixation of the bag–haptic complex, piggyback secondary IOL, bag-to-sulcus PC IOL exchange, secondary reverse optic capture, and primary reverse optic capture.

What is the most common cause of reduced vision after cataract surgery?

Sometimes blurry vision is caused by PCO, a fairly common complication that can occur weeks, months or (more frequently) years after cataract surgery. It happens when the lens capsule, the membrane that holds your new, intraocular lens in place, becomes hazy or wrinkled and starts to cloud vision.

Can you develop more cataracts after cataract surgery?

What holds new lens in place after cataract surgery?

Your lens is held in place by delicate fibers called zonules. If you've had an eye lens replacement for cataract surgery or refractive lens exchange, your intraocular lens implant (IOL) is held in place by a small sac and these thin fibers.

How long do intraocular lens implants last?

IOLs have been around since the late 1940s and were the first devices to be implanted in the body. Unlike natural lenses, IOLs do not break down over a person's lifetime and do not need to be replaced.
