Blurry Vision After Cataract Surgery

Secondary Cataract Causes Blurry Vision

Most patients decide to have cataract surgery because their vision is blurry.  The purpose of your cataract surgery is to correct your blurry vision.  Sometimes, months or years after cataract surgery the vision can become blurry again.  We call this a secondary cataract.

You may worry that the cataract grew back.  This is not the case.  Once the cataract (the cloudy lens in the eye) is removed, it cannot grow back.

When the cataract is removed, an intraocular lens implant is placed into the capsular bag that the cataract previously sat inside.  Up to 50% of the time after cataract surgery, the back of the capsule can become cloudy after cataract surgery.  Some people call this a secondary cataract.  This can occur months or even years after cataract surgery.  A secondary cataract is extremely common.

Symptoms of Secondary Cataractsecondary cataract causes blurry vision

You may notice increased in blurry vision or an increase in glare and mistiness of the vision.   You may notice halos around lights.  It is important for your comprehensive ophthalmologist to perform a comprehensive eye examination to determine the cause of your blurry vision.

Symptoms of a secondary cataract are very similar to the symptoms of having a cataract.

If I feel the blurry vision is due to opacification of the capsule (in layman’s terms a secondary cataract), I will discuss the risks, benefits and alternatives of the the treatment plan.

Yag Laser Capsulotomy

A Yag Laser Capsulotomy is a relatively simple procedure typically performed in my office.  The laser procedure is painless and only takes a minute or two.  No anesthesia is required and you can drive yourself home.

I will give you drops to dilate the pupil and numb the eye.  After, I will place a lens on the surface of the eye.  I will use a laser to make an opening in the capsule.   The purpose of the procedure is to improve your vision.

After a Yag Laser Capsulotomy

Your vision may be blurry for an hour or so after the procedure because of ointment used in the eye during the procedure.  I will give you a drop to use for approximately 5 days.  I will check you in my office 2-3 weeks after your procedure.

What is Astigmatism?

What is Astigmatism?

Astigmatism is a very common cause of blurry vision.  The eye is shaped more like an egg or football rather than an orange.  Either the cornea or the lens of the eye is not round if you have astigmatism.  Instead it is oblong.

It is often hereditary and you are often born with it.  Most people have astigmatism in their glasses prescription.  The amount and direction can change over time.  If you have astigmatism, objects can look elongated either vertically or horizontally.

Children and AstigmatismWhat is Astigmatism?

It is important that astigmatism is diagnosed in children at an early age.  Children may not complain of blurry vision.  If your child has a lot of astigmatism that goes undiagnosed, the visual system may not develop properly.  This can lead to a condition called amblyopia (lazy eye).  If your child does not pass a screening evaluation at either their pediatrician or school, it is important that they have a comprehensive eye examination to determine the reason.

Undiagnosed astigmatism can cause blurry vision and possibly difficulty seeing at school.  Refractive error is not affected if you child sits too close to the TV or reads in low light.

What Causes Astigmatism ?

Astigmatism can be caused by either the shape of the cornea or the lens.  The cornea is the windshield of the eye and the lens focuses light inside the eye.  If either structure is shaped more oblong, you may have astigmatism.

How Do I Treat Astigmatism?

You will want to have your astigmatism treated to provide the best possible vision.  It can be treated with glasses and / or contact lenses.  There are many contact lens options available.

It can also be treated with Lasik or Epi Lasek eye surgery.  Dr. Stanley Grandon and I can perform a thorough eye examination to determine if you are a candidate.

If you have astigmatism and require cataract surgery, we can evaluate you for a special implant to correct the astigmatism.  This implant is called a toric implant and can greatly reduce your dependency on glasses after cataract surgery.
