Here are some interesting LASIK eye surgery terminology and facts. If you are planning on having this type of surgery it is always good to familiarize yourself with it and the lingo. Dr. Jose Barraquer from Colombia in 1970 was the first person to develop the Microkeratome, an instrument that could cut thin flaps in the cornea and alter its shape. He is ultimately the one who made this type of corrective eye surgery possible.
This type of surgery is very safe and painless. Patients experience very little pain and usually fully recover within 24 hours. Their vision is noticeably improved as soon as the surgical procedure is finished. This sometimes frightens patients but only lasts for a short period of time. Here are some terms for your interest.
Laser-assisted In Situ Keratomileusis (LASIK) is a form of refractive laser eye surgery. This type of procedure is performed by an Ophthalmologist and is designed to help correct vision.
A Microkeratome is a precision surgical instrument with an oscillating blade designed for creating the corneal flap in LASIK or ALK surgery
Eye Surgery -
Ophthalmic surgery or ocular surgery, a surgical procedure performed on the eye or its adnexa.
Appendages of an organ.
The turning or bending of any wave, such as a light or sound wave, when it passes from one medium into another of different optical density. It is also the ability of the eye to bend light so that an image is focused on the retina, allowing the image to be sent to the brain for processing.
In Situ -
In situ is a Latin phrase used in many different contexts and means 'in place'.
A procedure for the correction of the refraction of the cornea by removing a deep corneal lamella, freezing it, forming it to a new curvature, and then replacing it.
A physician who specializes in ophthalmology.
Branch of medicine that deals with the anatomy, functions, pathology, and treatment of the eye.
Isn't medical technology amazing? Just knowing that if you were born with bad eyes that you can go spend a few thousand dollars and transform your sub-par vision into perfect 20/20 should bring some ease to your life. To your heath and to your life - farewell!

LASIK - Laser Eye Surgery
The refractive state of your eye can be improved and you can decrease the need for wearing glasses through Refractive Eye Surgery. The most common method of surgery followed today is Laser surgery, where lasers are used to reshape the cornea. Laser surgery is the greatest achievement in ophthalmology. Lasers are usually used to treat non refractive conditions.
What is LASIK?
LASIK is one of the most popular types of laser eye surgery. LASIK stands for Laser-Assisted In Situ Keratomileusis. This procedure can permanently reshape the cornea, which is the clear covering of the front of the eye, and change its focus power using an excimer laser. Millions of patients have been treated using LASIK, using of a wide variety of different lasers. This procedure can be used to correct myopia, hyperopia and astigmatism.
Prior to the surgery:
Before you undergo LASIK surgery you will have to get your eyes examined by a doctor to see if you are a good candidate. If you wear contact lenses, you will have to stop using them for 1 to 4 weeks before the surgery and switch to wearing your glasses, to allow the cornea to return to its original shape, or else this can have negative consequences like inaccurate measurements and a poor surgical plan; resulting in poor vision after surgery. These measurements would decide how much corneal tissue is to be removed, and have to be repeated a week after your first evaluation as well as before surgery, to see that the measurements have not changed.
During the surgery:
A small device called a microkeratome will be attached to the suction ring; the blade of which will be used to cut a thin flap on your cornea. The flap is created, exposing cornea tissue. After this, both the microkeratome and the suction ring will be removed. The doctor will now lift the flap and fold it back on its hinge, exposing a layer of tissue called the stroma - the middle section of the cornea.
You will be made to focus on a particular spot and the doctor will begin the laser to remove the corneal tissue, according to the measurements taken at the initial examination. The flap is then put back into position and left to heal.
After the surgery:
As no stitches are required, you will just have to wear an eye patch as protection to prevent rubbing, getting poked, or any kind of pressure that might disturb the healing process. It may take up to three to six months for your vision to stabilize after surgery. It is important that you know all about Laser Surgery before you go through with it - the benefits as well as the side effects if there are any. Consult with your doctor, as only he will be able to tell you if this surgery will be good for you. Once you have all the information needed, you can make the decision whether or not you wish to go ahead with the surgery, and give yourself the opportunity to see the world in a whole new way!
One of the great things about the age in which we live is that we do not have to put up with a lot of the problems our forebears did. Every day, new surgeries are being developed that help to enhance our day to day lives and one of those developments is Lasik surgery. Lasik is an acronym, which stands for Laser-assisted In Situ Keratomileusis. It is a procedure in which a patient has their eye sight corrected- no more glasses, no more hassle with contact lenses. Many people find that Lasik is a great alternative and it is a permanent solution- once you undergo the operation you will not have to do it again.
It is important that you tell your doctor all about your past and present medical eye conditions, and also the medications you are taking or if you are allergic to any medicines. Then on the day of the surgery you will be given a numbing drop so that you do not feel pain, although some patients do experience some discomfort. The area around your eye will be cleaned and a lid speculum will be used, which is an instrument to hold your eyelids open. A suction ring will be placed on your eye and suction will be created by applying very high pressure to the cornea. As a result of this, your vision will dim and the pressure may cause some discomfort.
Lasik surgery was developed in 1990, and the first Lasik operation in the United States occurred in 1991. There are three stages to the procedure, the pre-operative, the operation itself, and the post-operative. This article is concerned with what actually happens during the procedure, and how the operation corrects vision.
One of the strange parts about this operation is that it is performed while the patient is still awake, usually under the influence of a mild sedative as well as anesthetic eye drops. First of all, a flap of corneal tissue is created by using a mechanical microkeratome, which uses a metal blade. A femtosecond laser microkeratome can also be used. The latter device creates a series of tiny, closely arranged bubbles within the cornea. One end of the flap has a hinge attached to it, which folds back to reveal the stroma of the cornea. Next, an excimer laser is used to remodel the corneal stroma.
The laser vaporizes some of the corneal tissue while allowing precision control. This control means that adjacent parts of the stroma are not damaged by releasing the molecular bonds that hold cells together. The layers of tissue that are removed are mere micrometers thick, another advantage of laser precision.
After the cornea has been reshaped by the tissue removal de to the laser, the surgeon performing the operation places the Lasik flap back over the treatment area. This flap remains in place, protecting the eye until the tissue has healed. The advantages of this surgery, aside for sight correction, include the fact that the cornea has been "tricked", and does not send the message to the brain that would set off pain receptors.
A patient who has undergone the surgery can expect a rapid recovery time with very little pain involved. Lasik surgery has undergone a vast transformation in terms of accessibility and advancements in the last decade and a half. With more and more surgeons seeing the monetary opportunities inherent in the procedure, more have been trained and the result has been a decrease in cost- Lasik procedures today are half the price they were just five years ago! Lasik cannot be performed on everyone, so consult your optometrist to see if you might qualify.
Robert Moongrave operates a website dedicated to helping people find the best lasik clinics in their area.
Undoubtedly every patient and eye surgeon would want to accomplish the desired visual correction in the very first refractive surgery procedure. Surgeons typically conduct a comprehensive preoperative examination to determine whether the patient is a viable surgery candidate, and in order to predict the results of the refractive surgery. But unfortunately, it is difficult to accurately predict results in the case of higher refractive errors. Things gone awry during the preoperative examination or during the surgery itself may necessitate an enhancement surgery.
On certain occasions, the patient could well do without an enhancement surgery. Minor undercorrection and overcorrection can be treated through a technique called CLAPIKS (Contact Lens Assisted Pharmacologically Induced Kerato Steepening), which uses Rigid Gas Permeable (RGP) contact lenses to reshape the cornea and eye drops to make the cornea more malleable. However, other major issues may typically require enhancement surgery.
Finally, you should definitely arrange with a loved one for transportation to and from the LASIK surgery. Before LASIK surgery some doctors will arrange for you to take some medicine to help you relax that could impair your vision and reaction time. After LASIK surgery you may need a few days to recover your vision, hence the need to arrange for a drive home.
Even if your eye surgeon gives you the slightest hint of the requirement of an enhancement surgery, it is advised that you don't hastily demand enhancement re-treatment. You must wait for the eyes to settle down to a fixed refraction, before you decide on having an enhancement. Most enhancements are carried out between 3 and 6 months after the first eye surgery. This is because it is common for the eye to regress back to a fixed refractive error, and enhancement should not be performed until the regression has resolved.
A hyperopic patient is more difficult to predictably correct via surgery when compared with a myopic patient. And therefore, a hyperopic patent is more likely to require an enhancement surgery. If your initial eye surgery was LASIK or IntraLASIK, the surgeon would typically lift the existing flap and cut out the corneal surface at the location of the original flap. Though the LASIK flap adheres to the stroma, it can still be lifted, thereby averting the need to create a new flap.
With the advances in laser technology and an increase in the experience of eye surgeons, enhancement cases have significantly dropped. However, some cases might still occur that necessitate enhancement surgery. Enhancement surgery is not something to be anxious about, since an enhancement surgery would typically accomplish the desired results, which were somehow missed during the first surgery.
If you find a LASIK surgeon that you are confident with, you will be able to get more information about eye enhancement surgery.
What is Lasik Surgery?:
The word LASIK stands for Laser-Assisted
In Sutu Keratomieusis, a process which reshapes the cornea to refract light
in the lens. While LASIK surgery isn't close to perfect, it is a very viable
and increasingly safe surgery.
LASIK surgery is a very simple two step process:
A slight, thin flap of tissue is created on the outside layer of the eye or cornea. The flap helps heal and provide comfort on the way to better vision.
The doctor then folds open the flap on the inner cornea to correct the vision. Finally, the flap is closed to its original position and sealed with stitches.
Preparing for LASIK Surgery:
When you meet the doctor to
discuss LASIK eye surgery you should let him know a few things about yourself.
Let the doctor know about any past or present medical and eye conditions
as well as all medications you are taking or are allergic to. It is important
that you disclose all of this to your doctor before deciding if LASIK is
right for you.
After you've disclosed this personal information to the doctor, you should then discuss if you are a good candidate for LASIK surgery. Let him explain to you the risks, benefits, and alternatives of the surgery as well as what you can expect from beginning to end.
You should stop using any lotions, perfumes, or creams the day before the surgery as well as any makeup that may cause debris to get in the eye. The doctor may even request that you scrub and wash out your eyes for a good time before LASIK surgery to prevent the chance of any type of infection.
The Cost of LASIK:
When you are considering different LASIK
surgery opportunities you should question your surgeon on what is included
in the cost of the LASIK surgery. What is and isn't included in the LASIK
cost? What will I be charged for if complications occur or enhancements
are needed? What is the cost for LASIK medications such as anti-inflammatory
or painkillers? What is the cost for temporary contact lenses if they
are needed after LASIK? What is the cost of the follow-up visits related
Finally, you should get in contact with your insurance company to determine if they will cover the cost of the LASIK surgery. Some insurance companies don't cover LASIK cost because they consider the surgery to be cosmetic. If financing is not a problem you should strongly consider using the LASIK surgeon who best suits your needs and concerns.
The FDA considers the average cost of LASIK surgery to be $1,344 in 2005, a significant decrease from the original numbers listed in 2002 of nearly $1,600. Many consider this LASIK cost to be marginal in relation to the comfort created by newly improved vision.
After LASIK Surgery
The moments after a major life-altering
event are usually filled with joy, laughter, and camaraderie, but this
usually doesn't happen after surgery. LASIK surgery is no different than
any other surgery, but its drawbacks may be a little different than others.
The results of LASIK surgery are much akin to the results of being pestered by a pet day after day. Instead of the healing of bruises or incisions, LASIK surgery is accompanied by more burning and itching of an area that you are completely unable to scratch or cool. At this point, any touching of the eye could undo everything the surgery just repaired.
Your vision will be blurry because of the watering and tearing up of your eye, but you cannot under any circumstances touch your eye. The eye may appear dry or bloodshot for several days, if this occurs you should consider taking time off of work. If you experience severe pain from LASIK surgery at any time you should contact your surgeon.
Within 24-48 hours after your surgery you should have a post-operative exam to make sure everything is healing well. At regular intervals after the LASIK surgery up to six months you should continue seeing your doctor for checkups.
At the first visit after LASIK surgery your doctor will remove the shield and make sure your eye is responding correctly to the surgery. You will not be able to use contact lenses for sometime to keep from further irritation and you may have to use drops or artificial
