Many people don’t fully understand the details of LASIK eye surgery, even those who are undergoing or about to undergo the procedure. Don’t be someone who waits until afterwards to discover the things you should have known beforehand. Be an informed consumer, especially with something as important as your vision.

Lasik eye surgery is an innovation in the ground of eye care and a ray of hope for those who wish to get rid of their lenses and spectacles. It is a refractive surgery performed on eyes and helps to cure the defects of myopia, hyperopia or astigmatism. This surgery involves very little time and in a subject of few hours the patient can resume his normal day to day work. It has become popular worldwide because of its merits of low cost and convenience in its operations. There are number of Lasik eye surgery centers and the patient can conveniently walk in and get the operation performed.

The Lasik technology was first introduced way back in 1960 by a Spanish ophthalmologist. At that time, he developed the first microkeratome which was used to change the form of cornea and cut thin flaps in the cornea region. With more research in this field this technology has become accepted and affordable. Now Lasik eye surgery can be performed within a span of a few minutes with help of laser. Those planning for this operation are advised to stop wearing contact lenses 10-15 days from the time of operation. Plain laser surgery includes Epi-laser as well.

Lasik eye surgery is performed in 2 stages. In the first step a flap of corneal tissue is created in which corneal suction ring is applied to the patients eye. In this process, sometimes, blood vessel gets burst and resulting in bleeding, though gets resolved within few weeks. In the second step, excimer laser is used to remodel the corneal stroma. The Lasik laser in this stage is used for vaporizing of tissues in a controlled manner and then layers of tissues are removed which are tens of micrometers thick. At the second stage, the patient's vision becomes blurry and he or she is able to see only white light around the laser.

Lasik eye surgery has been developed in many forms. One of its forms is Wavefront guided Lasik wherein an ophthalmologist applies computers guided and guided excimer laser and it has measurements from a wavefront sensor laser technology. The goal of this is to restore perfect vision in the patients eyes. This technology does not result in super vision. You can't expect 100% eye vision from this. Yet, surgeons have claimed that patients who are treated by this method are more satisfied than with the previous methods. With the advantage of lower cost and easier surgery associated with it, this method is really becoming popular.

The Cost of LASIK Eye Surgery

The following are the pros and cons behind two of the most common misconceptions about LASIK.

1. “After the procedure, I’ll never need glasses or contacts again!”

Depending on your age at the time of the procedure and the issues with your vision that you’re trying to correct, you may or may not continue to need glasses or contacts, either immediately after surgery or possibly later on, as you age.

This is not to say that the procedure can’t be both effective and life-changing. It can be, and it generally is. The vast majority of patients who undergo the procedure report significant improvement in their vision.

It allows Massachusetts drivers to drive without glasses within days of their surgery. A small percentage require “enhancement” surgery, which is a second procedure, conducted to fix any over- or under-correction of your vision resulting from the first procedure.

Also, many people, as they age (generally between the ages of 40 and 50), develop poor vision for reading (called presbyopia). If you had LASIK surgery in Massachusetts prior to developing presbyopia, you could still need reading glasses as you get older. Presbyopia is sometimes treated with Monovision LASIK, which corrects one eye for distance vision and the other eye for close vision.

LASIK Eye Surgery - The Truth Behind the Misconceptions

Many people wonder if they may need "Laser surgery" after they have had cataract surgery. In fact, many people actually confuse cataract surgery for "Laser surgery." Actually, modern cataract surgery does not usually involve lasers at all. Instead, a microscopic ultrasound instrument (phacoemulsification probe) is used to break-up and remove a cloudy lens in a patient's eye. After the cloudy lens is removed, an artificial intraocular lens implant (IOL) is placed within the eye. In the vast majority of cases, however, no laser is involved in this process.

There are a couple of instances where lasers may be some benefit following cataract surgery. The most common is the development of a posterior capsular opacity (PCO) which is a thin, hazy film which can grow across the remnant lens structures behind the IOL. This hazy PCO can partially block the path of light through the IOL and obscure the patient's vision causing blurred haziness or glare. PCO is actually the most common complication after routine cataract surgery. If it becomes significant enough to limit a patient's functional vision, then it is generally treated using an instrument called an Nd:YAG laser.

This type of laser has been available for several decades and is extremely accurate and successful in clearing a PCO with little to no discomfort and with minimal recovery time. The Nd:YAG laser can be very carefully aimed behind the IOL to cut away an area of the PCO creating a new clear path for light to pass through. The procedure usually takes less than five minutes.

From the patient's perspective it is actually quite easy. The doctor places a plastic "contact lens" onto your eye which holds your eye open and also allows him to focus the laser beam. He then carefully aims the laser so that it cuts a small clear circular area in the PCO. Although there are bright lights involved, the patient typically feels little to nothing. The Nd:YAG procedure has a very high rate of success for restoring vision to a high level.

Another situation that can arise is the occurrence of residual refractive error (glasses prescription) even after cataract surgery with IOL implantation. In the case of a cataract patient, the IOL can be selected to match the characteristics of the eye thus minimizing the patient's glasses. If there is any residual refractive error, the patient may choose to wear glasses or it may also be possible to use the Excimer laser to correct it. For these cataract surgery patients, there are a number of things to consider.

First, they should understand that the standard IOL cannot change its focus so it is always set to either far or near distance only, but not both. Because of that fact, standard IOL patients require reading glasses if their distance vision is made perfect or they require distance glasses if their up close vision is good. These patients should consider carefully what distances are most important to them in their daily function before undergoing any Lasik vision correction. Also, there are now newer advanced technology IOLs (AT-IOLs) which are able to restore some ability of the eye to focus at different distances. These AT-IOLs are capable of reducing the need for glasses or bifocals to a greater degree than their older standard IOL predecessors. Prior to having cataract surgery, patients should ask their surgeons if they might benefit from the implantation of an AT-IOL.

Second, there are a couple of different ways to use the excimer Laser to correct a refractive error and surgeons have different approaches and philosophies. The two basic methods are called PRK and Lasik. Lasik is the most common vision correction procedure in younger patients that have not had cataract surgery, but many surgeons favor PRK for their cataract surgery patients. I personally prefer Lasik using blade-free Lasik technology. The major difference between PRK and Lasik is the creation of a corneal flap off the front of the eye in Lasik.

You can visualize the corneal "flap" as a wall calendar where one page can be flipped up to reveal the underlying page. Similarly, the hinged flap is created on the cornea and lifted up to reveal the underlying corneal tissue. The advantage of Lasik over PRK is the significantly faster healing and visual recovery. Some surgeons prefer the ease of PRK in post-cataract surgery patients because it avoids the need to surgically create the flap. However, the most advanced blade-free Lasik technology can very easily create the flap on post cataract surgery patients. These newer instruments place much less pressure on the eye than the older bladed flap-makers and can cut a corneal flap with far greater precision and accuracy as well. So the quick healing of Lasik can easily be applied to post cataract surgery patients and avoid the slow visual recoveries that can occur in PRK.

Modern cataract surgery is a very highly successful surgery whether laser surgery is required afterward or not and, in fact, the majority of cataract surgery patients never need laser treatment of any kind. Nevertheless, patients should be aware of the possibility that they may benefit in some cases from Nd:YAG or excimer laser (PRK, Lasik). Typically, these lasers will give added visual benefit after cataract surgery but are not absolute necessities. Your surgeon should explain the reasons and potential benefits as well as risks prior to having these additional laser procedures.
