How often does cataract surgery go wrong?

At a conservative estimate, at least 25% (or 1.5 million) of the six million cataract operations performed annually in developing countries will have poor outcomes. About one quarter of these poor outcomes are due to surgical complications.

What is the most common complication of cataract surgery?

A long-term consequence of cataract surgery is posterior capsular opacification (PCO). PCO is the most common complication of cataract surgery. PCO can begin to form at any point following cataract surgery.

How many cataract operations go wrong?

The risk of serious complications developing as a result of cataract surgery is estimated at around 1 in 50 cases.

What happens if cataract surgery goes wrong?

Another example of a cataract surgery complication is a malpositioned or dislocated intraocular lens. You may see the edge of the lens implant, or you may even develop double vision. If the intraocular lens becomes too badly dislocated, your visual acuity could decrease substantially.

Why is my vision getting worse after cataract surgery?

The “big 3” potential problems that could permanently worsen vision after cataract/IOL surgery are: 1) infection, 2) an exaggerated inflammatory response, and 3) hemorrhage.

How many days rest is needed after cataract surgery?

How long does it take for cataract surgery to completely heal?

Although some patients see well just a few days after cataract surgery, full healing can take up to three months. Cataract surgery recovery time tends to be minimal and mild, but there are various factors that can impact the speed of recovery.

Can failed cataract surgery be redone?

Cataract surgery cannot be reversed, since the cloudy natural lens of the eye is removed during a cataract procedure and cannot be put back in.

Can cataract surgery make astigmatism worse?

Recent research has shown that an astigmatism left untreated at the time of cataract surgery tends to worsen after cataract surgery. So, while the removal of the cloudy lens by the cataract will improve your vision, you may notice blurred vision caused by the worsening of your astigmatism.

What is ghosting after cataract surgery?

Some people describe halos, ghosting, slight overlapping of images (not double vision) and unexpected flashes of light. The medical term for all these changes is dysphotopsia.

What is Dysphotopsia?

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.

Can lens implants be redone?

Our answer is yes. If there is an issue with your IOL, it can be replaced with another one. This usually occurs when the lens does not provide adequate vision correction or causes problems like double vision. However, patients should keep in mind that the need for revision is rare.

What percentage of cataract surgeries have complications?

At a conservative estimate, at least 25% (or 1.5 million) of the six million cataract operations performed annually in developing countries will have poor outcomes. About one quarter of these poor outcomes are due to surgical complications.

What can go wrong with lens replacement?

Infection: lens replacement problems can include infection in a fraction of cases – less than 0.05%. Retinal detachment: the membrane at the back of the eye may detach following the procedure. This can be corrected by surgery but quality of vision may not be the same as before.
