Cataract surgery has been performed for many years, and new developments have dramatically improved the post-op vision. The lens is a normal structure of the internal part of the eye. We are all born with clear, natural lenses whose function is to focus light onto the retina, and also absorb dangerous wavelengths of light. Over time, this clear lens will become yellow, as its chemical structure changes as a result of years of light absorption, and general oxidative stress on the body. Early cataract surgery involved simply removing the cloudy lens from the eye. In order to see, the patient then had to wear very thick eye glasses, or a contact lens. As technology advanced, anterior chamber Intraocular lenses(IOL) were developed. These were artificial lenses that were placed in front of the iris to replace the removed lens. They worked very well, but over time the corneas were damaged in most of these patients. These anterior chamber lenses vibrated as a result of aqueous humor (fluid) flow from the back of the eye toward the front.
If you have been wearing toric contact lenses, why not add some color to your life with colored toric lenses? The lenses are made from the same material as common contact lenses. They can either be soft or rigid gas permeable (RGP). You can get toric colored lenses in blue, green, brown, gray, violet, and shades that are in between. As a matter of fact, you can even get lenses that look like cats' eyes or anything else that you can think of. These are great for Halloween or any parties where you really want to stand out from the crowd. The Different Types Of Lenses There are two kinds of colored toric lenses. Some that have to be removed every day before you go to bed and will last you around a year as long as you keep up with the cleaning routine and those that you can wear for around a week without removing them from your eyes. At the end of the seven day period, they are usually tossed out and a new pair worn. Their life can be prolonged to around two weeks if you are willing to go through the clean and store routine on a daily basis.
LASIK surgery: the path to better vision If you have been wearing spectacles or contact lenses for a long time, and dream of clear vision, then Lasik Surgery could well be your answer. Today an increasing number of people with poor eyesight are turning to this surgery to correct their vision. What is LASIK? LASIK is an acronym for Laser-Assisted In Situ Keratomileusis. The goal of the surgery is to alter shape of the cornea, which is the transparent covering on the eye. The process involves the use of a cool "excimer" laser. An instrument called a microkeratome is used to create a flap on the front surface of the cornea to reveal the stroma. This mid-section of the cornea is the portion of the eye which is reshaped with the excimer laser. This cool laser painlessly fixes the nearsightedness, farsightedness and astigmatism that causes poor vision. The potential risks involved As part of a LASIK evaluation by your surgeon, you will learn about the risks of surgery. Severe risks that can damage your vision are very rare.
FDA examines LASIK surgery complications. Nearly ten years after its arrival in the United States, and more than 3 years after FDA approval, LASIK surgery is coming under fire from some patients who have suffered complications or experienced poor outcomes. Today, the FDA heard testimony from patients who were dissatisfied with their LASIK surgery. Their complaints ranged from mild visual distortion, to pain, to severe activity-limiting visual halos and glare. One distraught parent read a suicide note from their child who described six years of eye pain and blurred vision. The vast majority of patients have near perfect vision after LASIK surgery. In fact, the procedure has been quoted by many as having a 99% satisfaction rate. Patients are, by and large, overjoyed with their results. Of course, like any surgery, LASIK has its downsides and patients need to be aware of the risks before they pursue this type of surgery. Surgeons in the U.S. perform about 700, 000 LASIK cases every year, and the surgery is a popular means of reducing the need for glasses and contact lenses worldwide.

In this day and age of high-tech solutions to just about every situation, it should be no surprise that there is a high-tech solution to vision problems through Lasik laser eye surgery. This procedure has become quite popular and for a number of good reasons. There is a fast recovery time, the vision improvement is virtually immediate and the risk of complications is super low. But, to be sure that the best results are achieved and to further minimize potential problems, there are a few things patients need to do after Lasik eye surgery. One of the first things that people want to know when they are considering corrective eye surgery is how long it will take, after the surgery, before they are able to return to their normal daily activities.

Today cataract surgery has become one of the most common and yet least debilitating surgeries out there. The procedure has become so patient - friendly that most people have great eyesight the very next day and with minimal discomfort following surgery. Most people can return to full function within 1 -2 days. What other surgery offers that? Unlike the senior citizens of yesterday, our older population today leads an active and busy lifestyle. They exercise, socialize and drive more than they ever did before and because of this, the timing of cataract surgery has changed in the field of ophthalmology. Previously we would wait until the cataract was "ripe". Now we base the timing of surgery on numerous issues including: difficulties with driving or reading fine print (on medication bottles or the newsflashes that move across the bottom of the television). After all, who doesn't want every driver out there to have the best vision possible? It benefits our entire community to keep every member as independent as possible, for as long as possible.
Laser eye surgery has certainly become very popular recently, despite the eyes being very complex parts of your body, it is a fairly easy procedure with very high success rates and eye opening results. However little is known about what laser eye surgery actually involves and who it can help. Short sightedness, medical term myopia, means that you can't focus on distant objects, which makes them look blurred. Myopia is very common and tends to run in families. The condition is caused when your cornea is too curved, or your eyeball too long, light rays from distant objects focus in front of your retina. This makes objects seem fuzzy or blurred. Around five million people in Britain are short-sighted. The condition usually develops in childhood or adolescence and is often first noticed at school. Hyperopia is a sight problem that affects your ability to see close-up objects. Commonly known as long-sightedness, the condition is a type of focusing error, and tends to get worse as you get older.
Something more and more employers are educating their employees about is proper eye safety. The type of eye care used is dependent on the work being done. It's obvious to some that when you are using large manufacturing tools where small fragments fly about often then eye safety would make sense. Yet, many neglect the 'simple things'. You don't have to work at a construction site to be mindful of your eye safety. Another area in which people are being educated is the safe keeping of your eyes on a day to day basis. Knowing what will keep your eyes safe and what equipment is available can prove most useful. Whether work, play, or leisure, there is much you can do, such as; Goggles/Safety glasses protect against flying debris. Even more so, it's good to know that this protective wear can aid in the protection of visible and near visible light or radiation. Goggles/Safety glasses should contain polycarbonate lenses. Sunglasses should protect against UV sunlight rays. Not all sunglasses have it.
