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.

The incidence of laser eye surgery complication is minimal however, if you're considering the procedure then you need to be aware of what they are as part of your preparation process.

The percentage of people who suffer corneal infection following surgery is less than one per cent. Delayed healing will be a hindrance to recovering patients but the long term effects with proper post operative treatment are almost negligible.

In this article, we'll highlight some of the most common laser eye surgery complications.

- Under or over correction probably heads the list of complications. This simply means a surgeon can't predict accurately the response of your eyes to treatment and you will be required to continue wearing protective eye wear following the procedure. In more severe cases, further surgery could be required.

- Corneal haze is common and related to PRK(Photorefractive Keratectomy). It's considered a common aspect of the recovery process and shouldn't effect one's vision after complete recovery. Corneal haze risk is not as common with patients who undergo lasik treatment.

- An annoying complication revolves around a condition known as regression. Simply put, despite the procedure, the eye returns to it's pre-operative state and depending on the patients risk factor, may require another operation.

- The halo effect is another annoying aspect of both PRK and lasik procedures yet it can be serious in some circumstances. A halo effect is a worrying complication for patients especially for those driving at night.

- Lasik patients could be prone to a laser eye surgery complication known as flap damage. In other words, a supposed hinged flap created on the center of the cornea could unexpectedly be dis-lodged. This will present problems if it's damaged and while it can be replaced following the treatment, this is not always 100% certain.

- The flap could also become distorted to the extent it could affect to some degree a patient's best corrected vision.

While risks are always present with any type of surgical procedure, the chances of suffering any major laser eye surgery complication are extremely low.

Surgeons may be reluctant to operate on patients who are considered a risk in the pre-operative stage. While this may sound harsh it's simple logic and the patients well-being is not going to be compromised.

Pursuing a Career in Ophthalmology

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 New York 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 New York 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.

How to choose a LASIK Eye surgeon in New York

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.

Lasik Eye Surgery - A Cost Effective Surgery

lasik dangers

Dry eye has been long recognized as a postoperative side effect of Lasik surgery. Studies have concluded that clinically detectable dry eye is present nearly universally following Lasik surgery, even when patients do not normally experience dry eye symptoms. There are a couple of causes of dry eye problems. First, when the corneal flap is created during the Lasik procedure, either a steel blade or a laser must cut through the corneal tissue and corneal nerves are disrupted in the process. The deeper this cut, the more likely the disruption to nerve tissue. The laser reshaping of the cornea further disrupts the nerve tissue. During the time while the nerve tissue heals and regenerates, the reflex to tear and blink is significantly diminished; thus creating the dry eye problem.

The quality and smoothness of the corneal surface and tear layer is important for quick recovery of good visual acuity. The tear layer is actually the first optical surface that light hits when it enters the eye during the Lasik procedure. If that tear layer is irregular or deficient, it can create a poorer visual image, with heightened "ghosting" or "fuzziness."

To maximize my patients' vision postoperative, I suggest approaching the problem of dry eye with a basic regimen that includes the following:

1) A good preoperative evaluation for preexisting dry eye problems and maximizing the surface condition prior to performing Lasik.

2) The usage of the Intralase FS lasers for making the initial Lasik flap rather than the steel razor blade microkeratome.

3) The good use of artificial tears and gel lubricants postoperative, even if the patient does not complain of dry eye symptoms.

I also suggest that patients use cyclosporine 0.05% eye drops (Restasis) twice per day for one month postoperative. Studies have shown that this regimen can improve visual outcomes and reduce the need for enhancements after Lasik surgery. It appears that the improved quality of the tear layer can actually improve a patients vision, so that they are less likely to feel the need for additional or touch up surgery. This not only improves the patients overall experience but decreases the possibility of any secondary side effects or complications that could occur with a second procedure, however rare that would be.

Ultimately, attention to detail with every aspect of surgery enhances the outcomes as well as patient satisfaction in the long run. That's why surgeons need to pay so much attention to new and innovative technologies and medications on every level as they are developed.
