Laser Eye Surgery Success Rate

Lasek Surgery Success Rates

Are there any risks with laser eye surgery?

LASEK surgery is used for those patients who are not suited to LASIK surgery, either because their cornea is too thin or because it’s not the right shape. It can be used to treat myopia, hyperopia and astigmatism. In the procedure, the eyes are anesthetised then a cut known as a pre incision is made in the cornea. An alcohol solution is applied to the eye, and a laser is then directed into the eye to reshape the cornea. A contact lens is then inserted, by the surgeon, to protect the eye during the healing process.

The success rates of LASEK are broadly comparable to those of LASIK however the healing period can be longer and more patients experience post-surgical pain after LASEK.

Laser Eye Surgery Has Fewer Long Term Effects Than Contact Lenses

When it comes to the chance of complications, laser eye surgery long term risks are significantly lower than some other vision correction solutions. Did you know that contact lens wearers are at significantly higher risk of complications? The risk of serious complications with LASIK eye surgery is less than 1%. With contact lenses, however, the risk of serious eye infections that can lead to blindness affects up to 1 out of every 500 contact lens users per year.

While laser eye surgery does come with a small risk of side effects and complications, serious complications are incredibly rare. Most LASIK side effects arent long term problems, and they typically improve with time as the corneas heal. Additionally, because laser eye surgery candidates face a rigorous screening process, only those whose eyes will respond well to laser eye surgery are offered the treatment. Despite such strict measures, around 92 percent of people are candidates.

To find out if youre a suitable candidate for any laser eye surgery, see your eye surgeon for a complete screening first. If youd like to talk to a professional about the long term effects of LASIK or another laser eye surgery, get in touch with our expert team at Dello Russo Laser Vision today.

What Is The Success Rate Of Lasik

The LASIK success rate or LASIK outcomes is well understood with literally thousands of clinical studies looking at visual acuity and patient satisfaction. The latest research reports that 99 percent of patients achieve better than 20/40 vision and more than 90 percent achieve 20/20 or better. In addition, LASIK has an unprecedented 96 percent patient satisfaction rate the highest of any elective procedure. .

Considering the above research it is clear that LASIK is a safe procedure that helps many patients improve their vision every year. For those considering a vision correction procedure, understanding the LASIK success rate is an important part of your research as well as understanding what these rates mean for your own vision goals.

What Is The Laser Eye Surgery Success Rate

So the laser eye surgery success rate with modern techniques is very good. In my hands, 99.5% of people have vision equal to or better than their spectacles or contact lenses with one treatment.

That of course, means that one in 200 people may need a second treatment. And the reason for that is not because the laser doesnt apply the treatment correctly or the procedure is done incorrectly. Its because everybodys eyes are different and some people respond in a different way to others. So occasionally, especially people with high treatments, maybe -8, may need a retreatment. And that rate is about 1 in 200.

What Happens During The Procedure

LASIK Eye Surgery: Better Vision with Laser Surgery

This procedure may be performed at a hospital or where there is a laser room. Your ophthalmologist uses eye drops to numb your eye and to make the pupil small. A special contact lens is put on your eye to help direct the lasers high-energy beam of light at the iris in your eye. The laser makes one or two holes in the iris. You will see a few brief flashes of light and feel little, if any, discomfort. The procedure usually takes less than 5 minutes. You will be able to go home soon after it is done.

Things To Consider Before Getting Lasik Eye Surgery

When determining if LASIK eye surgery is right for you, be sure to ask lots of questions. You should not rush into this decision. Discuss your medical history in-depth with your eye doctor, alerting them to all over-the-counter and prescription medications you take as well as any allergies. We will conduct a thorough preoperative examination and assess your eye health before recommending this procedure. If you wear contact lenses, you may need to switch to eyeglasses instead. Contacts can change your eyes cornea shape, resulting in inaccurate measurements during our exam. On the day of your procedure, do not wear makeup, lotion, eye cream, or perfume to avoid the risk of infection or complications during surgery. LASIK eye surgery is an outpatient procedure that is usually quick and painless. However, you will need to make transportation arrangements. Your vision will be blurry, and you may need to keep your eyes closed while adjusting and healing after your procedure. Certain factors like your age, prescription strength, and any additional eye problems may hinder the effectiveness of LASIK surgery. LASIK is not a one-stop solution for making your glasses disappear. Many steps are involved in the process, and you may still need to wear glasses post-surgery or come back for additional touch-ups.

Eye Problems After Surgery

For Jason Esveld, LASIK turned into an unexpected nightmare.

âI went in blissfully ignorant of what was really going on here,â says Esveld, 28. âI did my research when I bought a TV, but not when I decided to laser my eyes.â

In December 2016, about 4 days after having the surgery at what he now calls a âLASIK mill,â he had an unsettling pain in his right eye.

âIt was a deep ache and sometimes like a sharp, hot sensation, like when you have an inflamed ankle after you roll it,â Esveld says. âI would have days when it was so severe that I was pretty much incapacitated. I couldnât keep my eyes open because of the pain.â

With LASIK, which stands for laser-assisted in situ keratomileusis, lasers correct eyesight by reshaping tissue under the cornea, the round dome at the front of the eye. The doctor flattens the eye and cuts a flap to reshape the middle section of the cornea. The reshaping of the tissue changes the way light focuses in the retina, making your vision clearer. It can take up to 6 months for eyes to reach peak clarity and for some of the side effects to go away.

It isnât unusual for patients to have eye problems for the first time after LASIK, including halos, dry eyes, starbursts, and lessened night vision.

But the 28-year-old engineer wasnât convinced.

Esveldâs research led him to believe that LASIK had left him with ocular neuropathic pain, a result of nerve damage in the cornea.

What Is The Lasik Complication Rate

The LASIK complication rate is only about 0.3%. The most commonly reported LASIK complications are infection or dry eye that persists for more than six months. Other complications include:

  • Undercorrections occur when the laser removes too little tissue. Though rare, this does occur more often in patients with a higher prescription than those with a lower prescription. If an undercorrection is diagnosed during one of your follow up exams, an enhancement may be needed to get you to your vision goals.
  • Overcorrections happen when the laser removes too much tissue from the eye. Like undercorrections, an overcorrection may be addressed through an enhancement surgery.
  • Regression occurs when vision slowly changes back to the original prescription. This is not to be confused with the natural aging process of the eye, which will result in dim, yellowed vision due to cataract formation. Regression is one of the most rare LASIK complications.

What Are The Risks

What is the future of laser eye surgery?

Although there are some risks with the laser treatment such as inflammation, bleeding inside the eye, and raised pressure in the eye, the risks are fewer risks than with other types of surgery. Problems may occur that could threaten your vision, but they are rare. If you have any questions about the risks of this laser treatment, ask your ophthalmologist.

Who Makes An Ideal Lasik Eye Surgery Candidate

If you have been diagnosed with one of the following conditions, you may be a good candidate for LASIK surgery at Spindel Eye Associates:

  • LASIK for Farsightedness Farsightedness occurs in people with eyes that are shorter than average, which can cause blurred vision at a distance and near.
  • LASIK for Nearsightedness Nearsightedness is the opposite of farsightedness. Nearsighted people have longer eyes and have difficulty seeing objects that are far away.
  • LASIK for Astigmatism People with astigmatism typically have trouble seeing objects at any distance. This condition occurs in people with unusually shaped corneas. The cornea is the transparent cap covering the front of the eye.

New Hampshire LASIK experts Dr. Mohamed Guenena and Dr. David Vazan have listed some additional requirements below to help you gauge a better understanding of typical LASIK surgery candidacy:

  • Must be over 18 years of age
  • Must have a stable vision prescription
  • Must have a track record of healthy eyes
  • Must not have keratoconus
  • Must not have severe dry eye syndrome
  • Must not be pregnant
  • Complete dilated eye exam to review retina

What Is Laser Peripheral Iridotomy

LASIK Recovery Time

A Laser peripheral iridotomy is a surgical procedure in which a laser is used to create an opening in the iris so that fluid can leave the angle of the eye more easily. It is performed for patients with narrow angles, or angles that look like they might be prone to closure. Narrow angles may predispose one to an episode of angle closure glaucoma, in which raised pressure in the eye can rapidly threaten vision and even cause blindness.

The Long Term Side Effects Of Laser Eye Surgery

So then, what are the LASIK side effects long term and what should patients be aware of? The majority of side effects associated with LASIK and other laser eye surgeries are temporary. For most patients, these side effects improve with time as their corneas heal. However, there are a small percentage of patients for whom these side effects become permanent. Side effects can include:

  • Double vision, also called ghosting
  • Light sensitivity

These side effects are rarely a long term effect of the surgery and should get better over time. To minimize side effects, its critical that you follow all of your surgeons instructions to ensure that your eyes heal properly. That will help improve the likelihood that any side effects you experience are temporary and dont become a long term issue. Its also essential that you make sure you see an experienced eye surgeon. They will closely examine your eyes and conduct a thorough health screening before deciding on which, if any, laser surgery is right for you. This will also help reduce the likelihood of side effects.

Finally, look for a surgeon who offers custom laser eye procedures. The more personalized your surgery can be, the better results you can expect to get. Youll also experience fewer side effects in general because your surgery will be more accurate and able to precisely target your specific needs.

What Happens During Prk Surgery

After your initial consultation and the discussion of your treatment plan, you will be given a topical anesthetic substance or numbing drops to reduce any discomfort. They will use a speculum that is placed over the eye to keep the eyelids open during the procedure, which is painless. Within about 30 seconds, your eye surgeon will fully remove the topmost layer of your cornea which is called the epithelium. The next step is using an excimer laser tool to fix and reshape the cornea, which may take up to 60 seconds. After that, the surgeon will use a special bandage that is similar to a regular contact lens that goes on top of the cornea until the removed tissue grows back.

Why Should You Select Prk Surgery Over Lasik

PRK Surgery has been around since before LASIK eye surgery in Calgary became mainstream due to its quick recovery. It has a long history of success, and once the initial recovery process is over, you can be assured that there will not be any complications since the topmost portion of the cornea that is removed during the surgery fully grows back without any trace. Due to the flap created during LASIK that lasts after the surgery, there is always a risk of complications. Therefore, LASIK is not recommended for anyone with a risk of eye injury, which does not relate to PRK.

What Is Laser Iridotomy Eye Surgery

What is the success rate for ICL surgery treating astigmatism?

Laser iridotomy is the surgical treatment of abnormally high eye pressure. It is a medical precaution that your ophthalmologist may recommend if you have angle-closure glaucoma or narrow angles that are risk factors for glaucoma.

Narrow angle is when your iris is abnormally close to the cornea. With little, if any, fluid draining from your eye, pressure can quickly increase inside and damage the optic nerve.

Optic nerve damage that occurs this way is called angle-closure glaucoma, and it can slowly cause permanent vision loss. People on schedule for phakic lens implantation surgery may also need a laser iridotomy to prevent glaucoma.

Who Is A Candidate

Roughly 3 million people in the United States have glaucoma, the worlds second-leading cause of blindness. Eye doctors recommend laser iridotomy once careful assessment shows that the procedure can safely prevent vision loss in a patient with narrow angle glaucoma.

You may be eligible for the surgical puncturing of your iris if:

  • You have the angle closed for 50 percent or more of the available drainage channel, causing abnormal eye pressure or optic nerve damage
  • Youre at risk of abnormal eye pressure buildup and optic nerve damage due to a closed angle

Ophthalmologists perform laser iridotomy to alleviate eye pressure that threatens to cause long-term vision loss. The surgery takes only a few minutes, and its purpose is to minimize the development of glaucoma, the second-leading cause of blindness. The outpatient procedure can halt further vision loss, but it cannot reverse vision loss that has already occurred.

The Future Of Lasik Surgery For Children


Researchers are studying the effects of laser eye surgery for children who have rare vision problems. Studies show some evidence it could be beneficial to children who suffer from severe nearsightedness or farsightedness. These children are at risk of eye atrophy due to lack of use, and LASIK surgery may be able to help this from occurring. Even for this purpose, children usually try contacts to correct vision problems. Its when the contacts dont correct the problems that laser eye surgery may be a consideration.

The Truth About Lasik Success Rates For Astigmatism

Many patients dont realize theyre good candidates for the LASIK procedureand the LASIK astigmatism success rate is higher than ever.

Astigmatism is surprisingly common, and most people have at least a mild form of this condition. But when it begins to cause blurred vision all the time whether youre reading a book or gazing at a sunset its time to think about your options for a better quality of life.

LASIK is a refractive surgery that can correct these errors. When first developed in the 90s, the LASIK procedure was used only to treat myopia or nearsightedness. But for over two decades now the LASIKastigmatism success rate has improved greatly as doctors have perfected the use of the procedure. This laser eye surgery can help patients with astigmatism correct vision problems that contact lenses and glasses cant completely fix. For patients tired of the hassle of glasses and contact lenses, laser vision correctionprocedures are an increasingly preferred way to correct astigmatism once and for all.
