What is cataract article?
A cataract is a clouding or opacification of the normally clear lens of the eye or its capsule (surrounding transparent membrane) that obscures the passage of light through the lens to the retina of the eye. This blinding disease can affect infants, adults, and older people, but it predominates the latter group.
How do they fix cataracts?
During cataract surgery, the clouded lens is removed, and a clear artificial lens is usually implanted. In some cases, however, a cataract may be removed without implanting an artificial lens. Surgical methods used to remove cataracts include: Using an ultrasound probe to break up the lens for removal.
What is cataracts in your eyes?
A cataract is a clouding of the normally clear lens of the eye. For people who have cataracts, seeing through cloudy lenses is a bit like looking through a frosty or fogged-up window.
What is refractive corneal surgery?
When it comes to vision correction surgery, many patients immediately think of LASIK (laser-assisted in situ keratomileusis). This recognizable procedure is a type of corneal refractive surgery – a laser procedure that changes the shape of the cornea and how light reflects onto the retina, thus improving vision.
What is Hypertopia?
Hypertropia is a type of strabismus, or misalignment of the eyes. While some people have eyes that go inward (crossed eyes) or outward, hypertropia occurs when one eye turns upward.
What is cataract pathophysiology?
A cataract is a clouding of the natural intraocular crystalline lens that focuses the light entering the eye onto the retina. This cloudiness can cause a decrease in vision and may lead to eventual blindness if left untreated.
How long do cataract lenses last?
A cataract lens will last a lifetime, and the vast majority of patients do not experience any complications with their lenses after cataract surgery. In fact, the most common post-cataract surgery issue has nothing to do with your lens in particular.
How long does cataract surgery last?
How long does cataract surgery take? The total process, from the time a patient enters the office to when he or she leaves, is about two and a half hours. The procedure itself typically takes less than 20 minutes.
Can you see cataracts in the mirror?
If left untreated, a cataract will naturally continue to progress. In some cases, the maturing cataract becomes completely white and can be seen in the mirror or by others.
Can LASIK fix refractive?
What types of surgery can fix refractive errors? The most common type of refractive surgery is called LASIK (laser-assisted in situ keratomileusis). Most types of refractive surgery, including LASIK, use lasers to change the shape of the cornea. Some use other tools, like implants.
What is the cost of refractive surgery?
The exact price is determined after a thorough examination of both the eyes and understanding your health history. The complexity of your refractive error can affect the cost of your surgery, but you may expect to pay in the range of Rs 85,000 to 1,00,000 (approx.) for both eyes to achieve the most positive outcomes.
What is left Hyperphoria?
left hyperphoria (L/R) Hyperphoria in which the line of sight of the left eye deviates upward relative to the other eye. paretic hyperphoria Hyperphoria due to a paresis of one or several of the extraocular muscles.
