Is wearing lenses frightening

Cataracts - cataracts

At some point after age 50, the ophthalmologist will likely tell most of us: "You have cataracts." A cataract, also known medically as a cataract, is one Clouding of the lens of the eye.

The purpose of the lens of the eye is to refract the rays of light that enter the eye so that you can use them focus near and far can. Normally the lens should be clear, but with age it can become cloudy in what is called a cataract.

A cataract can do not correct with glasses, contact lenses or corneal surgery and would ultimately lead to impaired vision or vision if left untreated complete loss of vision to lead. As scary as it sounds, it isn't, because modern cataract surgery can almost always get that through Lens opacity restore lost vision. Any visual defects that may be present can often be corrected, so that the patient no longer or only rarely has to rely on glasses.

Cataract surgery

The Cataract surgery is a surgical procedure in which a cloudy lens is removed.

A Surgery is the only wayto remove a cataract. This removes the cloudy natural lens and replaces it with a clear artificial lens. This lens is called IntraOcular Lens (IOL) designated. If you have any questions about IOLs, please contact us. We will inform you about how it works and how it is treated.

How does cataract surgery work?

Before cataract surgery

Before cataract surgery, your ophthalmologist will do one comprehensive eye examination perform to check the overall health of your eyes and possible Identify risk factorswho might speak against surgery. Your ophthalmologist will examine and measure your eyes carefully to determine which right strength for your IOL to determine.

You will be after too Medication asked which you are taking. You may be asked to pause some of these medicines before surgery. You may also be prescribed special eye medications before surgery. These drugs help Prevent infections and reduce swelling during and after surgery.

On the day of the operation

A cataract operation can be performed on an outpatient basis in almost all cases; a longer hospital stay is not necessary. The attending physician proceeds as follows:

  • Your eye will be with Eye drops or with an injection numb around the eye.
  • you wake up during the operation and can see light and movement, but you will not see what the doctor is doing on your eye.
  • Your surgeon will tiny cuts (with a laser or a blade) put on the edge of your cornea (the clear cornea on the front of your eye). These incisions allow the surgeon to grasp and remove the clouded lens in your eye with very small instruments. Most modern cataract procedures make it cloudy Ultrasonic crushed lens and the Fragments then gently sucked out of the eye.
  • Then a new artificial lens (IOL) is inserted in the same place as your natural eye lens, i.e. directly behind the iris and pupil.
  • Usually there is no need to treat the cuts in the cornea as they will close on their own and over time heal without scars. The eye is covered with a bandage to protect it while it recovers.
  • A straightforward cataract surgery typically takes time only about 15 min. However, assume that you will be in the operating room for a total of 90 minutes or more, because that is how long the preparation (dilatation of the pupil, administration of the preoperative medication) and follow-up work take.
  • After a rest period of approx. 15 to 30 minutesyou can go home again. You should ask someone to drive you home after cataract surgery; Do not try to drive until your ophthalmologist confirms that you can drive again.

After the operation

While your eye is healing, you may notice eye redness for the first few days or even weeks after the procedure and your vision may be slightly blurred.

During the first week of your recovery, you should avoid the following:

  • Exhausting activities and heavy lifting.
  • Exercise and similar activities that may strain your eye while it is healing.
  • Avoid getting soap or water directly in your eyes. Keep your eyes closed while showering or bathing. Also, avoid swimming or hot tubs for at least two weeks.
  • Avoid anything that could bring pollutants, dust, or dirt into your eye. An eye infection could be the result.
  • Do not rub or squeeze the eye.

Here's what you should do:

  • You will need to use eye drops after the surgery as directed by your doctor.
  • Your eye doctor may ask you to wear glasses or an eye patch for some time to protect your eye. You should definitely do this when you are sleeping or exposed to strong sunlight.
  • Your eye doctor will talk to you about when you can get back to exercise, driving, or other activities.

If you have a Cataract surgery on both eyes you will usually need between the two procedures one to three weeks apart to let. This will allow your first eye to heal sufficiently and you will have good vision in that eye again when the second is operated on.

What Are the Risks of Cataract Surgery?

Modern cataract surgery is one of the safest and most effective surgical interventionsthat are done nowadays. Nevertheless, like any operation, cataract surgery can cause problems or complications.

Some of these risks are:

  • Eye infections
  • Bleeding in the eye
  • Eye swelling in the front or inside of the eye
  • Swelling of the retina (the layer of nerves in the back of the eye)
  • Pain in the eye
  • Loss of vision
  • The inserted lens can shift
  • Subsequent capsule clouding

Weeks, months, or years after the cataract surgery could be your Vision becomes cloudy or blurred again. This cloudiness is caused by cells that migrate between the IOL and the posterior lens capsule. The doctor calls this "after cataract" or "secondary cataract" (PCO = posterior capsular opacification); it kickedearlier in about 15 to 30% of cases.

Modern intraocular lenses therefore come with a Anti-PCO barrier which makes this complication less common. If it occurs anyway, it is a After cataract, however, can be treated quickly and easily. The cloudy cell membrane behind the lens is perforated centrally with a laser so that one can see clearly again. The eye does not have to be surgically opened again. The outpatient Treatment only takes a few minutes and is painless. After that, there is usually no new cataract.

Laser cataract surgery

Usually in cataract surgery, the lens is put through a mechanical cut away. The use of a laser for this purpose that laser-assisted cataract surgery, is relatively new. Studies have shown that using lasers in cataract surgery can improve the accuracy of certain steps.

Traditional anti-laser treatment for cataracts

What is the difference?

You may be offered two surgical options for cataract surgery: the classic cataract surgery or the laser-assisted cataract surgery.

We have already described how a cataract operation is carried out in principle. In laser-assisted cataract surgery, a Camera / ultrasound device positioned over your eye. The device sends detailed information about the surface of the eye and the lens to a computer, which programs the laser for the exact position, size and depth of the incisions.

The surgeon uses the Laser for cutting the cornea and opening the lens capsule. With the ultrasound probe, which is also used in conventional cataract surgery, the cloudy lens is then broken up and the fragments carefully sucked out of the eye. The new Intra-ocular lens (IOL) is implanted. As with conventional cataract surgery, the corneal incision usually heals by itself.

For whom is laser-assisted cataract surgery worthwhile?

Using a laser during cataract surgery enables the surgeon very precise and always consistent cuts in less time. Laser-assisted cataract surgery can be useful under the following circumstances:

  • If you have been diagnosed with astigmatism and you want your vision defect corrected during cataract surgery. In this case, the laser will make specific cuts in the cornea to treat the astigmatism. (However, this can also be done with an astigmatism corrective toric IOL.)
  • If you opt for a premium lens, such as a multifocal IOL, laser-assisted cataract surgery may be more suitable because the surgeon can see and image the lens capsule better and more precisely place the opening in the capsule. This enables better centering of the IOL, which is particularly important with premium lenses.

What advantages cannot the laser offer?

The Recovery time for laser-assisted cataract surgery and traditional cataract surgery is equal to. Some people can see clearly almost immediately, while others can see within about regain their eyesight in a week or two. Keep in mind that it can take around 3 months for your eye to fully recover after cataract surgery.

Laser-assisted cataract surgery does not lead to fewer complications or better visual results than conventional cataract surgery. With any type of cataract surgery, the outcome depends in large part on the skills and experience of your eye surgeon, not the method.

Your visual needs and expectations can help you and your ophthalmologist find the best surgical solution for you.

Lens implants (IOLs) for cataracts

An intraocular lens (or IOL) is a tiny artificial lens that is inserted into the eye. It replaces the natural lens of the eyethat is removed during cataract surgery.

The purpose of the lens of the eye is to refract the rays of light that enter the eye so that you can use them to focus near and far. If you have a cataract or cataract, this lens is cloudy. The cataract surgery removes the cloudy lens and replaces it with a clear IOL, whatever your Restores eyesight.

Just like glasses or contact lenses there are too IOLs in different focus strengths. Your ophthalmologist will measure the length of your eye and the curvature of your cornea and use this measurement to determine the focus strength of the IOL that is right for you.

What are IOLs made of?

Most IOLs are made of Silicone or acrylic. They are also coated with a special material to face your retina harmful ultraviolet (UV) rays from the sunto protect.

There are many types of IOLs available today, depending on your specific needs. In addition to IOLs that are used for nearsightedness and farsightedness, there are also toric IOLs that correct astigmatism.

In principle, one differentiates between the following types:

Monofocal lenses

The most common type of lens used in cataract surgery is the monofocal IOL. It only has one focus distance and is on Close, medium or distance vision set. Most people have monofocal lenses for distance vision and wear glasses for reading or close-range work.

Presbyopia corrective IOLs

There are also IOLs with it different refractive strengths within the same lens. After cataract surgery, these offer a larger field of vision than conventional monofocal lenses. If you wear such lenses, you will need glasses less or no longer at all. With such advanced presbyopia correcting IOLs, you can get your Improve visual acuity at close range without affecting your distance vision. The presbyopia correcting IOLs include the multifocal IOLs and the accommodating IOLs.

Multifocal IOLs

These IOLs offer distance vision and near focus at the same time. The lens has different zones with different refraction. Your brain learns to choose the right focus automatically.

Accommodation IOLs

These Lenses move or change shape in your eyeso that you are in see clearly at different distances can.

Toric IOLs

For people with astigmatism there is so-called toric IOLs. Astigmatism is a refractive error caused by a uneven curvature of the cornea arises. The toric lens is designed to correct for this refractive error.

Before cataract surgery, your ophthalmologist will not just tell you about that different types of IOLs explain what to expect before, during and after the procedure. This information is intended to help you make an informed decision about which to go for what type of surgery and intraocular lens you want to choose. If you have any questions or concerns about cataract surgery, please discuss them with your eye doctor or eye surgeon before undergoing the operation.

What does cataract surgery cost?

During the cataract operation the health insurances only cover the costs for the standard operation and the standard (monofocal) lens. The Surcharge for premium lenses and laser treatment you would have to pay yourself. This surcharge is generally not covered by the statutory health insurance companies. Private health insurance companies decide on a case-by-case basiswhether they will cover some of the additional costs. You should definitely clarify this with your health insurance company before treatment.
