Is refractive error correction cataract surgery? However, correction of refractive error during cataract surgery (i.e., replacement of the clouded lens with an implant) is not considered refractive surgery.
What happens during cataract surgery? In the most common cataract surgery procedure performed today, called phacoemulsification, the lens of the eye is liquefied and aspirated using an ultrasound probe. Subsequently, a foldable artificial lens is inserted into the body's own lens capsule. This is an extracapsular cataract extraction .
How long does inpatient cataract surgery take?
The inpatient stay will be about two to four days. Numerous preparations are required before the actual cataract operation. In order to avoid complications as far as possible, thorough preliminary internal examinations must be performed by the general practitioner or the internist in the clinic.
Which visual defects can be corrected?
But also visual defects such as nearsightedness or farsightedness and astigmatism (astigmatism of the cornea) can be corrected by a refractive lens exchange. Here you will find information worth knowing about the exchange of the lens in the eye.
Can cataract surgery be performed on an outpatient basis? However, outpatient cataract surgery can only be performed if the patient has a good general condition and subsequent comprehensive care at home is possible. Follow-up care at the outpatient ophthalmologist must also be ensured.
Is myopia a visual defect?
When seeing at long distances, your eye has no way to focus the image. Nearsightedness is a common visual defect, often occurs during school years and is not a disease.
How can it come with visual defects and visual impairments?
More detailed information can be found under the heading "Lens aberrations". Visual defects and visual weaknesses can also be caused by a mostly age-related clouding of the eye lens (cataract), by other diseases or by accidents.
What are vision defects and vision aids? Visual defects and vision aids. Visual defects are usually congenital, but can also develop over time. The most common are nearsightedness and farsightedness. It is also not uncommon to have a visual impairment for certain colors. Many visual defects can be corrected by glasses, contact lenses or surgical procedures.
What are the symptoms of low vision? Poor vision has a wide variety of symptoms and can have many causes. Constant stress and fatigue can also cause poor vision. It is not only older people who have problems with their eyes. All age groups can be affected by poor vision or eye disease.
What are the most common visual impairments?
The best-known visual defects are hyperopia, myopia, astigmatism and presbyopia. In addition, there are other forms of visual impairment such as double vision (diplopia) and amblyopia.
What are the side effects of surgery?
Most of the time you will only feel the touch, a gentle pressure or a small burning sensation. If she feels anything uncomfortable, let me know and I can gladly administer additional numbing drops. What are the risks or side effects of surgery? These depend on the nature of your condition and the surgery.
How long does the operation last untreated? Untreated, it lasts for about 2-3 hours. You may have a somewhat rough voice and sore throat after the surgery. This is due to the breathing tube that is in the trachea during the surgery. The feeling may last up to a few days after the anesthesia.
What is nausea and vomiting after surgery?
Nausea and vomiting after surgery is not uncommon, but in most cases it is harmless and short-lived. Rarely, however, complications can occur and respiratory disorders with oxygen deficiency or tearing of the esophagus may occur.
What can be involved in cataract surgery?
Near-sightedness is also possible, which entails glasses for distance vision. Cataract surgery can also correct other eye defects, such as astigmatism or different refractive errors in both eyes. Some ophthalmologists recommend adjusting one eye for distance, the other for near.
What are the most serious complications of cataract surgery?
One of the most serious complications of cataract surgery is the invasion of pathogens resulting in inflammation within the eye. This inflammation (endophthalmitis) can be so severe that the patient goes blind in the eye or, in the most extreme case, the eye even has to be removed.
What is removed during cataract surgery? During cataract surgery, your surgeon removes your eye's cloudy natural lens (cataract) and replaces it with an intraocular lens (IOL). During this procedure, much of the thin, clear membrane surrounding the natural lens, called the lens capsule, is intentionally left intact.
What are the most common visual defects in the eye?
The eye, even that of a child or teenager, can have one or another visual defect. The most common visual defects are nearsightedness, farsightedness and astigmatism. With age, the muscles of the eye also lose suppleness, and the eye becomes presbyopic, that is,
Why is the eye built too long? Nearsighted people have an eye that is too long, and the retina is too far back for the refractive power of the cornea and lens. The image reflected into the eye from a distance is only sharp in the place where the retina should normally be, but now is not.
Can the lens of the eye be curved? The eye lens cannot be curved so much that the refractive power becomes large enough. This would create an image not on the retina but behind it. As a result, farsighted people see near objects out of focus. Both visual defects can be corrected with glasses.
