Occasionally occurring in children or younger adults for genetic or medication reasons, this lens opacification affects most of us to some degree in later life. Age-related cataracts affect more than 22 million Americans. Fortunately, cataract removal surgery can restore vision by removing the hazy lens and replacing it with a clear intraocular lens (IOL) implant. IOL implants are prescription lenses that are specifically chosen for your eyes degree of nearsightedness or farsightedness, often reducing your need for glasses to see in the distance and, for some, resulting in only the need for inexpensive reading glasses. Also, IOL implant technology has advanced to allow premium lenses to neutralize astigmatism, which is irregular focusing of light into the eye, and even multifocal IOL implants to yield clear vision at distance and for reading at near. A question Ive often been asked is: Can cataract surgery be done with laser? Until recently, the answer was no, Hessler said. Laser refractive surgery, known by names such as Lasik (laser-assisted in-situ keratomileusis) and PRK (photorefractive keratectomy), has been popular in recent years. This technology reshapes the cornea the clear domed windshield on the surface of the eye to better focus light through the lens inside the eye and onto the retina, eliminating or reducing the need for glasses. While a viable solution for many, this treatment will not correct an eye with cataract, since the focused light still passes through the hazy cataract lens inside the eye. Your cataract surgeon must enter the eye through the cornea to access, then fragment and remove the cataract using ultrasound energy before placing the IOL implant. Modern cataract surgery allows the incisions to be tiny (only slightly larger than the diameter of a toothpick), resulting in speedy recovery and discharge home after the procedure lasting only about 20 minutes. Until now, the surgeon has had to create the corneal and lens access incisions manually using blades and instruments. While a practiced surgeon can accomplish this with great skill, new laser technology enables even greater precision in creating the incisions required in cataract surgery.

Some Professional Answers On Indispensable Issues In Astigmatism
Apart from the time taken to get used to wearing them, these contacts are very useful and should be used by anyone, who would like to get rid of their spectacles. no dataIt is possible to purchase these products on-line. Generally, such surgeries are done using lasers. Obtain a prescription from a registered optometrist and then purchase coloured contact lenses for your astigmatic eyes only from a known brand such as Freshlook, Acuvue, or prevision. LASIK or ‘laser in-situ keratomileusis’ is quite similar to the photo refractive keratectomy procedure. The lens capsule is retained for placing the intra ocular lens. Condition of Astigmatism and Presbyopia Many people are affected by astigmatism, which is a corneal medical condition that causes irregular shape of the cornea. People with weak eyesight may develop blurred vision if they swim without corrective lenses. Also, the shape and spacing of the rings are observed.
Complications: This surgery may cause complications, like corneal infections, displacement or folds in the corneal flap, slipped flap, etc. Most of the products have a shelf life of 1-2 weeks. After this, the patient may carry out with his daily activities; however, it is important to follow the instructions given by the surgeon to make sure that no complications arise during the healing period. Some feel that this cause displacement of objects and images. Too many eyen blinks occur as a response to a stressful situation. In this condition, the eyes cease to work as a pair and lose their alignment with each other. Water content of the lens is 45%. It is necessary to carry these contact lenses in contact lens cases. Many a time, musicians and instrumentalists develop focal dystopia of the hands, mouth and fingers as an overuse or overstraining of certain muscles has shown to cause a representative distortion of that muscle upon the cortical map. In this method, an artificial cornea is regenerated from a tooth of the patient, and is used to replace the damaged cornea.
Sometimes, it happens that multi focal contact lenses won’t work i.e. the eyes cannot adjust to them. Dryness of the eyes can be treated using the eye drops recommended by the doctor. no dataTender hair follicles may result tying your hair too tightly. Make a cup of hot black tea and pour it into a glass. It is because of this reason that old people have difficulty in viewing objects that are closer in view. Another option could be to do a laser eye surgery or eye accommodative surgery. Vision distortion is a common symptom reported by the patient. After graduation, a pupil does not go to a medical school, but instead has to attend a four-year postgraduate course in optometry. This makes coloured contact lenses, with or without vision-correction features, very useful in film making, modelling, professional photography and many areas of social life.
