Can You Go Blind After Lasik?

Getting blind after Lasik eye surgery is exceedingly rare and has never happened. Taking in the theoretical sense in case you got any kind of infection and the infection rate is very high then it may cause blindness otherwise it is very much rare. If the infection is not treated well and isn’t taken care of properly then it may lead to blindness.

How is Lasik Performed?

So, if we consider the most commonly performed procedure that is laser eye surgery. There are two steps to it,

The first step is the creation of a flap in the cornea with a fantastic laser. If you move during that part of the procedure the worst thing that could happen is that you wouldn’t be able to proceed with the LASIK flap on that day.

That following day you can put on an aspect of the course and see just as well as if you had absolutely nothing done, on that day you wouldn’t be able to see any evidence. As the laser had done anything to your cornea. 

So even with that scenario, you are totally safe.

The second stage of the Lasik procedure is undertaken with excitement later to the emulator using archival led light. polish away very gently from the exposed part  after that doctor lifts the flat that procedure is controlled by an infrared eye tracker

The patient should be kept in a calm position. 

For that part of the procedure, the laser takes over and it tracks the eye and responds within two milliseconds to any kind of iron movement so even if the eye flickers just slightly the laser moves with the eye.

So it has a perfect alignment and registration of the treatment planned and being delivered onto the surface of the eye.

 

What happens if the Surgery Fails to be Successful?

 If the patient looks away completely, the laser within two milliseconds stops and it just waits for the eye and the patient to return and then the surgeon can resume back with the surgery.

So the technology looks afterwards all the time all the way through so that even in the scenario of a patient. If you were doing treatment above all they are safe nothing can happen that can lead to an FS outcome and blindness is completely rare in this regard. So one should not be worried about this particular thing. Lasik is a completely safe and secured procedure performed for the correction of vision and getting rid of spectacles.

 

What’s Doctor say in this Regard?

When an eye doctor is talking about blindness it’s pretty darn serious and also very rare. As far as Lasik there are two kinds of complications.

Number one intraoperative during the surgery and number two post-operative after the surgery.

 

What are the Intraoperative Complications?

Intraoperative problems that occurred during the procedure have two parts to the Lasik procedure: the first is the flap creation and the second is the refractive procedure.

First is flap creation if there’s something that’s going to go terribly wrong during the procedure. It would more likely be related to the flap creation this is where a flap is cut traditionally with a blade but more recently with a laser in the cornea and the tissue is peeled back. 

when Lasik was first developed in the early 1990s the device to cut the flap called a microkeratome had to be assembled by the surgeon at the time of the surgery one critical peace separated the blade from the rest of the device think about a wood plane for shaving a plank of wood, unfortunately, there were a couple of cases reported.

where this spacer was either put in wrong or not put in at all the result was that rather than cutting a thin flap the device actually sliced into the eye those cases required emergency surgery to repair the last duration.

However, these did not result in blindness but they did significantly affect the vision Fortunately modern microkeratomes come pre-built only need the blade inserted so it’s impossible for them to do this.

Now the flap is more commonly being performed by a different kind of laser.

It performs micro-perforations which are then blended dissected by the surgeon

The surgeon does not likely see the appearance of depth of the laser ablation they can abort.

The second part of the procedure is called a refractive procedure. After the flap is lifted if things have gone well so far another kind of laser called an XMR laser is used to remove a small amount of corneal tissue.

The amount of tissue depends on the degree of correction desired. The lasers use sophisticated software to do this while the surgeon watches through the microscope.

Most lasers have tracking mechanisms to follow small eye movements, larger eye movements result in the laser shutting off temporarily.

In earlier versions that did not have eye trackers, the treatment could be decentered resulting in blurry vision. Sometimes requiring other treatments are correct. So there’s very little chance for this step to cause major problems.

 

What are the Post-Operative Complications?

The second kind of complication is called post-operative and this occurs after surgery.

If there’s something that could potentially lead to blindness after. Lasik or any other eye surgery would most likely happen after the surgery, not at the time of surgery.

  1. These are the most serious patients who are on antibiotic drop one week after the surgery and advised to refrain from swimming the yard, work working with animals, etc. In other words common sense you just had eye surgery, so cool it for a week or so Most infections of the eye actually come from your own body.

A serious infection could cause severe damage to the cornea in rare cases requiring a corneal transplant but as serious as this is it would not necessarily result in blindness.

The infection would have to penetrate into the eye in order to cause actual blindness.

  1. The traumatic loss of the flap getting poked in the eye with a tree branch or a motor vehicle accident these are the kinds of things that could rip off a flap but there are some pretty bad injuries and the flaps it worst were just dislocated and could be repositioned back into place worst-case scenario.

The flap is ripped off and lost. The surface of the eye would heal over and then the patient would either wear a concept lens to see or they would have to have a PRK laser procedure to get corrected again number three diffuse lamellar keratitis.

It is caused by different factors such as chemicals or detergents used on surgical instruments is common now as the known factors have been eliminated from use for the most part but it could result in damage to the flap especially if it’s not detected early by the surgeon and treated promptly.

So now you can go get your LASIK procedure and not worry so much make sure the surgeon is experienced and it is being performed in a reputable place. Don’t price shop for the cheapest deal. Although These are your eyes we are talking about here.
