Buying guide for contact lenses

Contact lenses have been populated much in recent days and many people embraced contacts as a substitute to their shabby glasses and often as an add-on to their style statement. This popularity came from the perfection of corrective aims of those lenses compared to spectacles. Medical studies have recently exposed facts related to approximately twenty percent of all premature babies who may develop such visual distortions as strasbismus or crossed eyes, amblyopia or lazy eye or serious refractive eyes when they are three years of age. They need strong thick glasses to wear in order to rectify the problems and have had chances for developing cataract. As they are children, lenses would better befit their eyes than those high-strength glasses.

There are cases that people going for the decorative purpose of contact lenses are developing some ocular problems because they avoid advice. Both the FDA and the Federal Trade Commission (FTC) have regulated sales of contact lenses. They involve certain regulations in order to buy a contact. For example, you better opt for your lens with a valid contact lens prescription, and it is because no other than an eye care professional can understand your eye condition and prescribe accordingly.

The right choice of lenses depends on several factors concerning your refractive error, the toleration power of your eyes, your dependence on the lenses and frequency of use. More information will the discussion provide you about how to pick suitable contacts for you.

First you have to decide how often you are to wear your contacts. Most people, who wants contacts for full-time use, wear soft contact lenses. On the other hand, if you choose to wear it on a daily basis, you would have gone for rigid gas permeable contacts. Masses wearing RGP contacts, may feel some sort of irritation, but after befitted into your eyes properly, it can give sharper vision. If you need contact lens to wear overnight, you can take one some lenses that allow an adequate amount of oxygen to pass through the cornea. It may not be safe for your eyes and the tolerance power of your eyes need a check by your eye doctor.

If you have crossed 40 years and need bifocals, then multifocal contact lenses may produce balmy effect on your eyes while you are engaged in study. If you have eye allergies and your eyes tend to be dry, then, before wearing contacts, you need advice from an eminent eye care professional. Recently, allergy-free lens care for stiff lenses are available in the market which helps to cope up with this adverse situation.

To add a fresh new look to you, color contact lenses are available. This type of contact lenses are broadly prescribed for the patients suffering from colorblindness. Though it may, to some extend, help them to recognize colors effectively, but can not cure it permanently. Non-corrective colored lenses are commonly used in theatres and films as it drastically changes the natural eye color and give a dramatic outlook.

The History of Laser Eye Surgery

Laser eye surgery is one of the most valuable medical developments of our lifetime. It has given ophthalmologists a tool to improve sight and in most cases eliminate the need for glasses for good.

Since the new technique was perfected in the late 1980s it has transformed thousands of lives and continues to grow in popularity. This highly specialised procedure allows surgeons to reshape the eye’s cornea correcting the faults that cause blurring of vision. The treatment can be used to correct both Myopia (nearsightedness) and Hyperopia (farsightedness) so the days when thick glasses or contact lenses were the only option to see clearly are gone.

The idea of laser eye surgery has been around since the 1950s and was the result of several different doctors who all played a part in the advance of the procedure. The technique was initially the innovation of Jose Barraquer, a Spanish ophthalmologist who first came up with the idea of cutting into the eye’s cornea to alter its shape.

Twenty years on, the radial keratotomy procedure was developed by the Russian doctor, Svyatoslav Fyodorov, who stumbled upon the important finding when he was treating a boy who had fallen and cut his eye on his glasses. Fyodorov discovered that by shaving off the front layer of the eye the young boy had recovered with better sight than before.

The development of the Excimer laser by a group of scientists from the University of California turned the eye surgery dream into a reality and, because of the inventiveness and dedication of these doctors, the first pioneering surgery was performed in 1989 in Greece. Since then the operation has become a common procedure performed around the globe.

Further developments to the procedure have resulted in two main types of laser eye surgery. Photorefractive Keratectomy, commonly known as PRK, a procedure carried out on the surface of the eye, and LASIK surgery, which differs because of the incision made to the surface of the eye and the laser treatment that is applied to the corneal tissue beneath.

Because of the delicate nature of an eye the operation needs to be performed with great care and, although the technology sounds complicated, in the hands of a qualified practitioner it is a relatively straightforward one. In general, the operation takes around 30 minutes although the actual laser treatment can take as little as a minute.

The technology and development of laser eye surgery has resulted in a simple painless procedure with a very quick recovery time. Today the surgery boasts a 95% success rate with most patients enjoying full 20/20 vision which is a testament to the brilliance of the doctors who invented the ground breaking operation.

Fold, Unfold and Go – The New Intraocular Lenses

One of the most important developments for cataract patients in the past few years has been <a href=http://www.katzeneye.com/eye_care_services/cataracts.html>intraocular lenses (IOLs)</a>. These tiny prescription lenses were created to replace the focusing power of the eye’s natural lens during <a href=http://www.katzeneye.com/eye_care_services/cataracts.html>cataract surgery</a>. Prior to the introduction of IOLs, cataract patients had to wear thick glasses or special contacts after surgery, making them essentially blind without their glasses.

Currently, more than one million IOLs are implanted each year in the United States, giving cataract patients the best vision of their lives. Intraocular lenses were originally introduced as inflexible lenses that required larger incisions. Now, technology has provided ophthalmologists with two different types: hard and foldable. The advantage to foldable lenses, made of acrylic or silicone, is that they can be folded up and inserted with a much smaller incision, then unrolled within the eye.

Advances in Intraocular Lenses

The foldable lens is just one of the advancements in intraocular lens technology. After the U.S. Food and Drug Administration approved the first IOL in 1981, IOLs found widespread acceptance and manufacturers saw other potential applications, eventually pushing for more IOL variety. Those choices include:

  • Multifocal lenses – offering variable distance viewing with greater possibility that glasses or contacts will not be needed. ReZoom™ and ReStor® provide clear vision at all distances and offer greater freedom from eyewear than traditional monofocal IOLs.
  • Toric IOLs – reduces or eliminates corneal astigmatism and greatly improves distance vision without the need for corrective lenses. The Staar Surgical IOL and the AcrySof® IQ Toric IOL will help the blurriness at all distances often caused by an ovoid corneal shape.
  • Accommodating IOLs – a revolutionary lens design that after implantation will change focus as the patient views objects at varying distances. The Crystalens® is controlled by the same eye muscles that controlled the natural lens.
  • Aspheric IOLs – a lens that provides better contrast sensitivity than other IOLs. The Tecnis® IOL is a good choice for those who often drive at night, as it provides clearer vision in low light conditions.
  • Filtering IOLs – can restore the natural eye’s ultraviolet (UV) light filtering that is removed in cataract surgery. Other IOLs have blue light filters; blue light is thought to play a role in causing age-related macular degeneration.
  • Monofocal lenses – an older type of IOL offering vision at only one distance that can be augmented by the use of glasses or contacts.

Cataract surgery has become a simple procedure with an excellent success record. So, for those who view the world as if they peer through a steamy bathroom mirror, IOLs have made seeing a great deal more enjoyable.

Katzen Eye Group in Baltimore and Lutherville, Maryland was one of the nation’s first ophthalmology practices to use the intraocular lens implants for surgery. For more information about intraocular lenses, please go to the Katzen Eye website.

Discover the Comfort and Flexibility of Modern Bifocal Reading Glasses

Bifocal reading glasses remain an excellent option for comfort and function despite the ever-growing popularity of vision-correcting contacts. I personally prefer the comfort and flexibility of a modern pair of bifocal reading glasses over any kind of fancy contact lens.

The modern bifocal encompasses a wide range of sophisticated eyeglasses. We now have bifocal sunglasses and bifocal computer glasses, both of which allow you to function normally and in style without requiring you to switch eyeglass frames. You don’t need to simply use the classic Franklin glasses, which feature that line between the different lenses in your frame.  No-line bifocal reading gasses are becoming more and more common.

Some people still envision heavy, large and thick glasses when they think about bifocal glasses.  In fact, with modern materials like CR-39 and polycarbonate, the manufacturing of bifocal lenses is more versatile and capable than ever. Whether you desire a rimless or semi-rimless appearance or a progress lens with multiple prescriptions combined into a single frame, you can obtain that all today with a light, sturdy and stylish bifocal reading glass.

The modern bifocal reading glass isn’t just a reading glass.  You can wear them for watching tv, working on the computer, going for a jog or cozying up with your favorite novel.  They’re light and comfortable and their ability to provide multiple prescriptions allow them to be useful in any environment without swapping them out for another pair of glasses.

Contacts can be messy and uncomfortable.  The process of putting them in, taking them out and cleaning them can be an incredible inconvenience if you have any activity in your life at all. Why not at least consider the cool new frames you can use with modern bifocal reading glasses.

How Phakic Intraocular Lenses Differ from Crystalens

Today’s advanced vision technology offers two excellent options for patients seeking improved vision.

The Verisyse™ Phakic Intraocular Lens

Verisyse is a Phakic Intraocular Lens (IOL) implanted in the eye, either temporarily or permanently, to improve moderate to severe nearsightedness. The term “phakic” refers to an eye that retains its natural crystalline lens. In nearsightedness, the cornea, or front surface of the eye, bends light rays so that the light focuses correctly on the retina. Therefore, the cornea is too steep, focusing light rays in front of the retina and causing blurry vision.

The Verisyse Phakic IOL is implanted behind the cornea, on the iris, for improved focusing of light and, therefore, improved vision. The cornea remains in place and continues to focus between far and near objects. People who wear thick glasses or contact lenses and do not qualify for LASIK are excellent candidates for the Verisyse Phakic IOL.

Verisyse lenses are made from PMMA, a material used successfully in cataract surgery for over fifty years. The implant procedure is performed on an outpatient basis under local anesthesia and takes approximately thirty minutes. The best candidates for the Verisyse Phakic IOL are:

Crystalens™ Accommodating Intraocular Lens

Crystalens™ is a multifocal IOL designed specifically for replacement of the eye’s lens after cataract removal. Crystalens is made from a flexible silicone that features a hinged design. This means Crystalens™ can work naturally with the ciliary muscles of the eye so that the eye can “accommodate”, or shift its focus between distant and close objects. With monofocal IOLs, this ability is lost and the patient requires glasses or contact lenses to see clearly at all distances.

Crystalens™ is implanted using nearly identical surgical techniques as for cataract surgery. Success rates are high and millions of people today enjoy improved vision and freedom from corrective eyewear after cataract surgery because of Crystalens.

The best candidates for Crystalens are individuals who are:

Does one of these solutions sound right for you? Schedule a consultation with an experienced eye surgeon to determine whether you are a candidate.
