cataract(treatment)

Treatment The early symptoms of cataract may be improved with new eyeglasses, brighter lighting, anti-glare sunglasses or magnifying lenses. If these measures do not help, surgery is the only effective treatment. Surgery involves removing the cloudy lens and replace it with an artificial lens. A shroud should be removed when vision loss interferes with your daily activities such as driving, reading or watching TV. You and your eye care professional can decide together. Once the benefits and risks of surgery, you can make a more informed decision regarding whether cataract surgery is right for you. In most cases, delaying cataract surgery will not lead to long-term damage to your eyes or the surgery more difficult. You should not rush into surgery. Sometimes a curtain should be lifted, even if it does not cause problems with your vision. For example, a curtain should be removed if it prevents examination or treatment of another eye problem, such as age-related macular degeneration or diabetic retinopathy. If your eye care professional finds a curtain, you do not need cataract surgery for several years. In reality, may never need cataract surgery. Through your vision tested regularly, you and your eye care professional can discuss if and when you might need treatment.
Surgery

Standard cataract surgery is usually performed in a hospital or an outpatient surgery center. The most common form of cataract surgery today is a process that phacoemulsification. Using an operating microscope, your doctor is a very small incision in the eye or near the surface of the cornea. A thin ultrasound probe is inserted in the eye is used to distribute ultrasonic vibrations (phacoemulsify) and cloudy lens. This part of the small fragmented are then suctioned through the same ultrasonic probe. After the cataract is removed, an artificial lens is placed in the same thin capsular bag that cataract occupied. This intraocular lens is essential to focus your eyes after surgery. There are three basic techniques for cataract surgery:
Phacoemulsification:
The most common type of cataract removal as above. In this most modern method of cataract surgery can usually be done in less than 30 minutes and usually only minimal sedation and numbing drops, no stitches to close wounds, and no patch after eye surgery.
Extracapsular cataract surgery:
The procedure is used mainly for very advanced cataracts where the lens is very difficult to resolve in fragments (phacoemulsify) or objects that have not phacoemulsification technology. This technique requires a larger incision cataract so that it can be removed in one piece without scattered within the eye. An artificial lens is placed in the capsular bag phacoemulsification technique. This surgical technique requires a different number of stitches to close large wounds, and visual recovery is often slow. Extracapsular cataract extraction usually requires an injection of numbing medication around the eyes and an eye patch after surgery.
Intracapsular cataract surgery:
This surgical technique also requires a larger wound than extracapsular surgery, the surgeon removes the entire lens and surrounding capsule together. This method requires intraocular lens is located in another country, in front of the iris. This method is still rarely used today, but may be useful in case of major trauma. various types of intraocular lenses implanted after cataract surgery? If the natural lens plays a vital role in focusing light for clear vision, artificial lens implantation at the time of cataract surgery is necessary to provide the best visual results. Because the implant is placed in or near the original position of the removed natural lens, vision can be restored, and peripheral vision, depth perception and image size should not be affected. Artificial lenses are intended to remain permanently in the country, do not require maintenance or treatment, and are not felt by the patient or observed by others. There are many styles available for intraocular lens implantation, including mono-focal, toric and multifocal intraocular lenses cal.
1. Mono focal lens:
These lenses are the most implanted lenses today. They have equal power in all regions of the lens and high quality can provide a focal point in the vision (usually distance). They usually only a short distance glasses for optimal vision correction. However, no mono-focal lenses correct astigmatism, an irregular cornea elongated shape that can distort vision at all distances, and require corrective lenses for all near tasks such as reading or writing.
2. Tory Schenardi lens:
Toric lenses have more power in a certain region of lens (similar to the glasses with astigmatism correcting them) to correct astigmatism, which can be improved without a vision for many individuals. Due to the change in lens power in different areas, the correction of astigmatism with a toric lens requires economic front lens in a very specific configuration. While toric lenses can improve distance vision and astigmatism, they still need corrective lenses for all near tasks such as reading or writing.
3. Multifocal lens:
Multifocal intraocular lenses have a variety of different regions of power in the lens with which individuals can be seen at various distances, including distance, intermediate and near. Although promising, multifocal lenses are not for everyone. They can lead to considerably more than glare or mono focal toric lenses. In addition multifocal lenses can not correct astigmatism, and some patients additional surgery such as LASIK to correct astigmatism and maximize their unaided vision.
