Cataracts

A cataract is the clouding over of the eye in the crystalline lens. It can cause blindness if not treated. Ask questions here about classifications, signs and symptoms, cause, treatment and history.

What does a cataract surgery procedure involve?

First, an incision is made in the eye. These incisions used to be quite large (at least by today's standards). You may even know people who had surgery over thirty years ago who had to stay in bed for weeks with sandbags on their eyes in order to keep these large incisions closed. Today, however, the incision is often less than three millimeters wide. That's about twice the thickness of a standard door key. The incision is so small that a suture might not even be necessary for the eye to heal.

Once an incision is made in the eye, a clear gel (called a viscoelastic or viscosurgical device) is injected into the eye. This gel protects the cornea from the ultrasound energy and keeps the eye pressurized during surgery.

For many surgeons, the most challenging part of cataract surgery comes next: creating a small round opening in the membrane that holds the cataract in place. This membrane is called the capsular bag. As membranes go, this one is pretty thin: somewhere between five and fifteen millionths of a meter thick (that's about 0.0004 inches thick). Hard to imagine? Well, it's hard to see. Not only is it at the limits of what the human eye can discern, it's also transparent! Other things that are about this size include individual particles of fog, a large spec of household dust, or a small spec of pollen. Amazingly, most experienced cataract surgeons are able to successfully create a round continuous opening in this delicate, transparent membrane. Occasionally, the capsule does tear. If this happens, your surgery may take longer to complete but most people still do very well.

Once the opening in the capsule has been created, the cataract (or natural lens of the eye) is removed using an ultrasound probe. Essentially, the cataract is broken into small pieces (emulsified) and then removed (aspirated) from the eye. Once the natural lens is removed, the capsular bag is polished and some additional protective viscoelastic gel is placed in the eye.

Now that the cataract is gone, the eye is ready for placement of the intraocular lens (IOL). The IOL is most often folded, placed through the incision, and unfolded in the capsular bag - just where your old lens (the cataract) used to be. Occasionally the IOL will have to be placed in front of the capsular bag or iris. Sometimes it is even necessary to sew it in.

After the IOL is placed in the eye, the protective gel is removed, If necessary, a suture is placed at this point to seal the incision. "Sutureless," or "No Stitch" surgery has been a big selling point in the advertisements and marketing materials of many cataract surgeons. The obvious implication is that having a suture is somehow inferior to surgery without a suture. Although the majority of my cataract surgeries are done without the use of a suture, it is important to note that sometimes a suture is a good idea. Don't be drawn in by glitzy advertisements. What is important is that you get the best possible surgery for your eye. Not everyone is a good candidate for sutureless cataract surgery.

Once surgery is complete, the eye may be covered with a protective shield to be worn overnight. The entire process (from the time you enter the operating room until a shield is placed over the eye) is often less than an hour.

Can Viagra affect cataract surgery?

Your eye surgeon is the best person to answer this as your personal condition will effect that decision. Optimally though, you should wait at least 24 hours after surgery to start driving again.

When were cataracts first discovered?

The first references to cataracts and their treatment in Ancient Rome are found in 29 AD in De Medicinae, the work of the Latin encyclopedist Aulus Cornelius Celsus.

What is the main cause of cataract?

The eye uses a transparent lens over the pupil with which to focus etc. A cataract is where the lens becomes cloudy and opaque (not see-through). This leads to blurred vision and if left untreated, blindness.

From my A-level studies, I know that prolonged exposure to UV radiation increases the chances of developing a cataract- which is why sunglasses often have UVA/UVB ray filters in.

Cataracts can be spotted by opticians by modern methods and equipment. The cataract can be easily removed (my grandma has just had hers removed). A small cut is made in the eye (after anaesthetic etc!). The cataract is removed with a rod, while a new synthetic lens is placed into the eye. The operation takes around 30 mins and has extremely high success rates. See the NHS website for more details.

How To Cure Cataracts Through Eye Surgery?

Everybody - no matter how old - is at risk to develop cataracts, and a cataract can basically be defined as a small growth on the lens of the eye that clouds the vision by obscuring the lens.

There are several different types of eye surgery that can be recommended to someone suffering from cataracts, and, exactly which surgery option will best match which patient depends on factors like the cataract’s size, cause and location. Another important factor is the age of the patient, and, generally speaking, the younger the cataract patient, the quicker the cataract should be removed as infantile cataracts can lead to severe sight loss and, perhaps, blindness.

Of the three most common types of cataract eye surgery, two are deemed fairly invasive while the third involves only a tiny incision. This third procedure - phacoemulsification - does not even require the patient to stay overnight in the hospital, and this treatment option works best on small cataracts. Briefly, phacoemulsification is an ultrasound procedure that makes use of an ultrasound probe that emits ultrasonic vibrations to dissolve - emulsify - the cataracted lens tissue. The probe is then used to remove the emulsified cataract debris from the eye, and the patient, after being given a small amount of medication to numb the affected area, is released from surgery. All in all, this procedure should take between 30 and 45 minutes to complete and is by far the least complex of the three.

The other two procedures - extracapsular and intracapsular cataract eye surgery - are more invasive than phacoemulsification and are used to rid a patient of medium-sized and severely advanced cataracts. Both procedures involve fairly large incisions into the eye, but, while extracapsular surgery comprises the removal of the cataracted lens, intracapsular surgery comprises the removal of not only the cataracted lens but also the ocular capsule that surrounds the lens. Intracapsular cataract eye surgery is, however, not as common as it once was and is fast giving way to the easier and more convenient ultrasound procedure.

Cataracts, if untreated, can lead to blindness, but, given the recent advances in cataract surgery, blindness can be prevented.

What happens if they remove the lens from the eye?

  1. it'll hurt like you wouldn't believe
  2. if you've pulled enough to tear the optic nerve, you'll be permanently blinded.
  3. if you've "only" damaged the eyeball, and get under specialist care, doctors may be able to preserve some function in the eye.

Make sterile 9 normal saline at home for eye irrigation?

Simply mix salt with luke warm drinking water. You will need to add 1 teaspoon of salt for every litre of water to create a normal (isotonic) saline solution.

You should make sure that you use a salt that doesn't have added iodine or anti-caking agents though. This usually means that table salt is out of the question, but kosher or pickling salt should be fine. When mixing the solution, bear in mind that it is best to err on the side of extra salty, as hypotonic (not salty enough) solutions are thought to be harmful and can sting quite a lot.

Can you drive after cataract yag laser surgery?

Well, this is a bit like answering the question, "Will I be able to play the piano after cataract surgery." Assuming, of course, that you were able to drive prior to surgery and have no other physical or mental issues that could limit your ability to drive the answer is "yes" with some caveats:

1) Anyone who has just had cataract surgery should NOT drive the day of surgery or the day after surgery.

2) It is generally best to ask one's personal eye surgeon if the vision after surgery is good enough to begin driving again.

3) With the standard monofocal intraocular lens (IOL) that is covered by insurance, many patients will likely still need glasses for their best driving vision after cataract surgery. Some of the newer "premium" IOLs can give you excellent driving vision without glasses by also correcting the eye's astigmatism or asphericity.

Hope this helped.

Can cataracts from chemo be removed?

No. Drops may delay further damage (clouding); however, they are not able to repair any existing damage.

To successfully treat cataracts, a cataract surgery must be performed.

Who gets cataracts?

Most are caused by a change in the chemical composition of the lens resulting in a loss of transparency. These changes can be caused by aging, injuries to the eye, certain diseases, conditions of the eye and body, and heredity or birth defects.

What is cataract mean in social studies?

The lens inside the eye is critical for crisp, clear vision. Without it we would need glasses as thick as Coke® bottle bottoms to see the world clearly. For most of our lives, the natural lens is flexible and clear - allowing us to see objects both in the distance and at near. Around the age of forty-five, however, the lens becomes rigid and is no longer able to change focus. This leads to the condition known as presbyopia. Although annoying, this condition is generally treatable with reading glasses or bifocals.

However, with time the lens in the eye hardens further resulting in blurred vision. Just as a piece of plexiglass exposed to sunlight will slowing turn grey, then yellow, then brown, so do our lenses lose clarity and change color. A discolored, or cloudy lens no longer allows all of the light through to the retina. When it blocks enough light to limit vision even with spectacles, the lens is generally considered to have become a cataract.
