The term LASIK is derived from the term Laser Assisted In Situ Keratomileusis that, in simple terms, means that the cornea of the eye is operated on with minimal disturbance to both the eye and the patient. One of the major benefits for this type of surgery is that it’s usually pain-free, with great results and rapid recovery.
Intralase Lasik Laser eye surgery takes approximately 20 minutes. It is also worth noting that, in the unlikely event that complications should arise, patients will be given a 24-hour hotline number to ring in order to receive immediate help and advice on the night after their treatment.
The procedure is quick and painless, and is sometimes called ‘The Gold Standard’ in laser surgery because of its superior benefits. One of the most important of these benefits is that the patient recovers rapidly.
This speedy healing process is due to the fact that lasers are used during the whole procedure rather than a more invasive blade, the Microkeratome, which has been used in earlier versions of LASIK surgery. The Intralase technique uses a femtosecond laser to create the corneal flap, minimising any side effects.
Once the flap has been created with the laser, the surgeon re-shapes the cornea to correct the patient’s prescription (also with the laser).
Optimax was the first company in the UK to offer this advanced treatment. Recovery time for patients is reduced and another major benefit is that this new technology allows a greater range of eye conditions to be treated.
The corneal flap made by the femtosecond laser is created perfectly and is repositioned once the operation has been completed. Specialists have noted that a very high proportion of patients achieve 20/20 vision following the operation, and complications are minimal.
Your Guide To Contact Lenses – medical chemical corp
Contact lenses have come a long way since they first came out. Individuals with vision problems now have a variety of different options for when it comes to choosing a type of lens. For those of you who don’t know, contact lenses are thin plastic lenses that fit over your cornea (the thin, front part of your eye). These lenses are used to correct vision problems such as nearsightedness, farsightedness, or astigmatism. Individuals should talk to their eye doctor about which type of lens would work best for you, however in the meantime it never hurts to consider your options. Here are a few of the different types of contact lenses currently available on the market today:
Soft contacts are made of a type of plastic that is combined with water. The water in these lenses lets oxygen pass through the contact lens to your cornea, thus increasing comfort, reducing dry eyes, and aiding in the health of your cornea. What many people love about soft lenses is that most of them are disposable which means that you can throw them away after using them for a short time. Having a fresh pair of lenses reduces your chances of infection. Other soft lenses are used for about a year and require you to clean them each night. These are typically more custom designed contact lenses. Sometimes soft lenses may even provide UV protection. One disadvantage to this type of lens is the fact that they are so fragile and can tear easily.
These contact lenses are lightly tinted, making it easier to find your lens if you happen to drop it.
Enhancement tint lenses have a translucent tint to enhance your natural eye color.
These lenses are darker, opaque, and change the color of your eyes. Many individuals use these contact lenses for cosmetic reasons. Some colors available in this lens are violet and green.
Rigid Gas Permeable Lenses
These lenses are made from silicone materials and let oxygen pass through them to your cornea. Many prefer this type of lens because they offer clearer vision than contacts with soft lenses and are extremely durable. On disadvantage is that they take a little longer to get used to the way they feel in your eye.
Other Types Of Lenses
These are only a few types of contact lenses available for those who need contacts. There are also bifocal lenses, toric lenses, etc. Talk to your eye doctor before purchasing contact lenses to see what is best for you.
Vision Loss: Is Caffeine the Culprit? – medical chemical corp
Are you one of the many people who just can’t do without a nice cup of coffee to help you through the day? Many people use a cup of coffee to help wake them up in the mornings and put some “umph” into their day or to keep them up a bit longer so they can get some much needed work done. Whatever your reason for drinking your cup of coffee, this article will provide you with some vital information on the how caffeine affects your windows to the world – your eyes.
Evidence from a Study
A report published in the journal Investigative Ophthalmology & Visual Science relates that people who drink coffee may need to reconsider the amount they consume as a means of reducing the risk of developing loss of vision or blindness. This study was the first of that nature to be done in the US.
In his explanations of the findings, author of the study, Jae Hee Kang ScD, cited the relationship between the coffee drinking habits of the Scandinavian people and the high occurrences of exfoliation syndrome and glaucoma among their populace as an example. Scandinavians have the highest incidences of these eye conditions as well as the record of being the highest consumers of caffeinated coffee on a worldwide scale. Hee Kang went on to explain that a recent study done by the research group showed that people who consumed greater amounts of caffeinated coffee had an increased risk of developing primary open-angle glaucoma. The study was done as a means of ascertaining whether or not the “risk of exfoliation glaucoma or glaucoma suspect” is impacted by the consumption of coffee.
The meta-analysis from the research revealed that when compared to those participants who did not drink caffeinated coffee, those who had three or more cups of the beverage per day had a higher risk of developing the eye conditions (glaucoma exfoliation or glaucoma suspect). Women with a family history of glaucoma had a greater risk of developing the condition. No correlation was found between other caffeinated beverages such as chocolate, soda, tea or decaffeinated coffee.
What You Should Know About Caffeinated Coffee and Glaucoma
* Drinking caffeinated coffee may increase the incidence of exfoliation glaucoma, which in turn causes the pressure within the eye to rise high enough to cause damage to the optic nerve.
* Presumed exfoliation glaucoma can cause slight damage to your optic nerve.
* People who develop exfoliation syndrome could end up with open-angle glaucoma as well as angle-closure glaucoma because the condition often causes both conditions in the same individual.
* Not everyone with exfoliation syndrome develops glaucoma, but the risk of doing so is six times greater for them.
What Can Coffee Lovers Do?
* If you are a lover of caffeinated coffee the best advice you can be given if you wish to protect your eyesight is to cut down on your intake of caffeinated coffee.
* If you already have any of the conditions then the use of special glasses will make your life easier. People who use the pinhole glasses have reported having great improvements in their vision.
