Can lasik cause cornea ulcers?

Rarely. It is possible to get an infection in the cornea as a result of lasik surgery. It is a very rare event however. Great care is taken to prevent this from happening with the use of antibiotic drops and antiseptic surgical technique.
No. If the flap is made by a blade there is a small chance of having a corneal abrasion. Corneal ulcers may come from untreated dry eyes or contact lens over wear.

Is it ok to perform lasik even if with history of corneal ulcer?

Depends. If you have a healed small peripheral corneal ulcer that is well healed yes. But if the scar is where the flap is made and is involved more than 75 microns of superficial cornea then most surgeon prefer to do prk so the flap does not become irregular or button holed. That is true even with femtosecond laser flap maker. Read more...

Why are corneal ulcers a risk of lasik? I want to get lasik but I'm worried about the risks of corneal ulcers. How dangerous are corneal ulcers, and why is it a risk after lasik? .

The . The risk of infection with lasik is extremely low overall. Your surgeon should place you on prophylactic antibiotics that are in general quite effective at preventing infections with lasik. Obviously - if an infection were to occur - it needs to be treated promptly - and in most cases - the vision still ends up good with a bacterial infection following lasik. Thankfully - the risk is very low - certainly lower than the risk of infection with long term contact lens wear best regards william trattler, md www.Centerforeyecare.Com. Read more...
There's . There's not a high risk of ulcers after lasik or lasek. There is actually a higher risk with contact lenses for ulcers, as the plastic lens traps bacteria, which cause the ulcer or infection we have published studies showing that the newer, noncutting lasek procedure is actually safer overall than wearing contacts, because once you heal your ulcer risk is zero. In comparison, every year you are wearing contacts your risk of a severe ulcer causing loss of vision is 10x higher than if you don't wear contacts. These results have also been published the risk if much higher if you wear contacts overnight. In my opinion, and that of most eye surgeons, fda should disallow contacts to be sold and marketed for extended wear, as this is unsafe after lasik or lasek, you are given an antibiotic drop to use to prevent infection. If you use it, the chance of infection is almost zero, because modern antibiotic eye drops are so effective. The best ones today are fluroquinolones, which were invented by one of my mentors when i was a medical student at columbia (howard neu, md) i switched from performing lasik to lasek 6 years ago, because lasek is safer. For example, if you get a bad infection after lasik, it's between the flap that was cut in the lasik and the underlying corneal bed. The flap acts as a barrier for antibiotic penetration, so sometimes i had to bring my patient back into the or, lift up the flap, scrape off the bacteria and pus, and instill the antibiotic directly on the bed to kill the infection. This sometimes resulted in epithelial ingrowth from all that flap manipulation, which is hard to erradicate, and can induce astigmatism and compromise vision in contrast, after lasek any infection that is present is right on the surface of the eye. I can always sterilize the surface, if necessary, because the antibiotic drops are directly hitting the bacteria, so they are easily killed off. If necessary, i can even use betadine (an iodine solution) to sterilize the surface of the eye (it's an antiseptic, not an antibiotic, so bacteria cannot be resistant to it, because it causes their cell walls to explode) basically, operating on the surface in lasek is safer than cutting flaps in lasik, because any infection you might have would be on the outside of the eye, not inside, and so much easier to eradicate, and cause much less serious problems hope this helps!:).

In . In 16 years of doing lasik surgery, I have never seen a corneal ulcer. I am not sure I have ever even seen anything more than mild inflammation! the risk of vision damage from infection after lasik is somewhere between 1-250000 and 1 in a million. Still, we all use an antibiotic drop preventatively, rather than waiting for an infection to start. I have seen either ulcers or inflammatory infiltrates after lasek twice, possibly due to the exposed surface after the cells are removed to perform the surgery. Both responded well to treatment and ended up with excellent vision. Read more...
With . With any surgery, there is a small risk of infection. With properly performed lasik, this risk is incredibly small. Most infections can be treated but they can cause corneal scarring if severe. The risk of decreased vision related to a corneal ulcer after lasik is very rare. Read more...
