While making a decision about LASIK surgery (Laser-Assisted In Situ Keratomileusis) or PRK (Photorefractive Keratectomy) advised by your NV eye doctor, you will most likely come across many controversial information that will ultimately make you confused.

Here are some wide spread myths on LASIK surgery and PRK which can clarify some points for you:

1. Laser Surgery Is Risky

Every surgery brings along certain risks, but if the right measures of precaution are taken by your NV eye doctor, LASIK or PRK surgery is considered as quite safe. According to experience of an ophthalmologist, Stephen Wilson MD, in 16,000 surgeries he has performed, there was one case of mild infection which was successfully treated with antibiotics.click this site!

Also, there is a risk of less than 1% that your vision will not be fully corrected.

As regards the common risk connected to the laser eye surgery known as transient eye, according to dr. Wilson there is no evidence showing that laser eye surgery leads to permanent dry eye, and if the procedure is performed properly, the patient is not more likely to get dry eye than anyone else.

2. You Will Need Reading Glasses

Dr. Wilson stresses that average age of his patients receiving laser surgery are over 40 years, and many of them monovision with LASIK or PRK surgery. He also says that “The dominant eye is fully corrected for distance, and the non-dominant eye is left slightly nearsighted, which helps with near vision.” Most people do not have any problems adjusting, but it can happen that some people are not able to tolerate or adjust to monovision. For this reason, your NV eye doctor can emulate the procedure and prescribe contact lenses. This can show how well can the patient adjust before the surgery.

3. Impossible To Correct Farsightedness By LASIK or PRK surgery

Dr. Wilson says: “We can correct almost all refractive errors individually, or combined, with the lasers we use today, with the exception of extremely high corrections. Many other patients with very high corrections can be treated with phakic intraocular lenses (IOL).”

While Making A Decision On Lasik Or PRK surgery

Try to make your own research as much as you can. Usually there are patient handbooks available, and your NV eye doctor should give it you. Do not focus on the cost of the surgery, as this decision is very important and will have a long-term effect on the rest of your life. If you see eye centers advertising with 100% guaranties and package deals, you should think twice.use this link for more tips:http://www.belfasttelegraph.co.uk/life/features/coleraine-man-has-sight-like-a-fighter-pilot-after-undergoing-a-new-optical-laser-eye-treatment-in-northern-ireland-34163477.html

LASIK surgery

When it comes to medicine, there are no guarantees. Besides, you should compare the experience and performance of the surgeons you are considering with a specific procedure. It is not just about how many surgeries the doctor performed, but also how many of them were done correctly. In addition, there are some risks related to the devices to be used (depending on the manufacturer)

We hope this information will help you out when making a decision on your LASIK or PRK surgery.

Henderson eye care provides all the services and treatments you need to maintain and preserve your eyesight, including keratoconus and similar eye diseases. Here are some information you should know on keratoconus and the types of lenses used in this case;

What Is Keratoconus?

 Cornea is a critical part of our eyes, since it focuses the light rays and enables us to see clearly. An eye disease which causes normally round cornea to become thin and unable to retain its round shape is known as keratoconus. It changes the shape of the cornea and in this way distorts our vision which creates discomfort during normal daily activities (reading, driving, etc.) The role of contact lenses for keratoconus is to correct our vision and reduce its effects on our eyesight. There are various designs of contact lenses suitable for different stages of keratoconus offered by Henderson eye care.read this post here!

 To be on the safe side, the best way is to entrust the choice to an experienced professional such as Henderson eye care when making the decision. There is no such thing as the best possible contact lenses for keratoconus, as the best ones are those that fit you best, correcting your vision and boosting the corneal health.

Here are some information on different types of contact lenses for keratoconus;

Soft Lenses

• This type of lenses unite the complex mathematics and latest technologies providing great vision and long-time comfort for people with keratoconus. At Henderson eye care, we often recommend this type of lenses to the patients engaged in sports, since they fit closely to the eye.

RGP Contact Lenses

• RGP (Rigid Gas Permeable) contact lenses are made of oxygen – permeable polymers, so they retain their structure when we blink, which sharpens our vision. ‘Rigid’ refers to the type of lens, and ‘Gas Permeable’ concerns the lens material. There are various designs of RGP contact lenses offered by Henderson eye care. In any event, ‘rigid’ from RGP is not related to the level of comfort as RGP provide the same level of comfort as the soft lenses. However, as regards the initial comfort, they sometimes require a brief adaptation period. Also, these lenses allow your eyes to “breathe”, as the oxygen-permeable silicone enables the front surface of the eye to get more oxygen as compared to the soft lenses. Besides, they are excellent for problematic corneas, multifocal designs, including keratoconus.

Hybrid Lenses

• Hybrid lenses for keratoconus combine an RGP center and soft periphery. This combination of the clear optics of RGP lenses and comfort of soft lenses is available at Henderson eye care in a wide range of designs and parameters.click this original post:http://www.smithsonianmag.com/smart-news/how-contact-lenses-were-made-and-fitted-1948-180957028/?no-ist

Scleral Lenses

Contact Lenses For Keratoconus

• This is a type of large contact lens resting on sclera (white part of the eye) and vault over the cornea. They are designed to alleviate various eye conditions, in case other treatments do not work. Scleral lenses are large, but their advantages can easily surpass this handicap. Their size makes it extremely difficult to fall out. Besides, dirt particles usually do not get under the lenses. They are pretty cozy as the edges lie below and above the eye lid margins.
Piggy-backs

• Piggy-back lens also known as “piggy-back” fit is a two lens system, with an RGP lens on top of a soft lens
