When is laser eye surgery not possible
Are your eyes healthy? – In general, laser eye surgery is most appropriate for people who have a moderate degree of refractive error and no unusual vision problems. Your eye surgeon will ask detailed questions about your eye health. The surgeon also will evaluate your eyes to make sure you don’t have any conditions that might result in complications or poor outcomes of surgery. These include:
- An eye disease that results in continued deterioration of your vision and thinning of your cornea, such as keratoconus. In fact, if keratoconus runs in your family, even if you don’t have it, be very cautious about elective eye surgery.
- Inflammation, such as keratitis or uveitis; and infection, such as herpes simplex.
- Eye injuries or eyelid disorders.
- Dry eyes. It is important to know that if you have dry eyes, LASIK surgery may make the condition worse.
- Large pupils. If your pupils are large, especially in dim light, LASIK may not be appropriate. Surgery may result in debilitating symptoms such as glare, halos, starbursts and ghost images.
- Glaucoma. The surgical procedure can raise your eye pressure, which can make glaucoma worse.
- Cataracts.
You might also rethink having LASIK surgery if:
- You have severe nearsightedness or have been diagnosed with a high refractive error. The possible benefits of LASIK surgery may not justify the risks.
- You have fairly good vision. If you see well enough to need contacts or glasses only part of the time, improvement from the surgery may not be worth the risks.
- You have age-related eye changes that affect your ability to focus up close, called presbyopia.
- You actively participate in contact sports. If you regularly receive blows to the face and eyes, such as during martial arts or boxing, LASIK surgery may not be a good choice for you.
Who should not do eye surgery?
Who is Not Suitable for Laser Eye Surgery? – Cheasapeke, Virginia Beach Last Updated: August 31, 2021 Not everyone is a good candidate for laser eye surgery. There are several reasons why laser eye surgery may not be a good choice of vision correction for some patients.
Below is some information about who is not suitable for laser eye surgery: Those who are younger than 18 years old. Laser eye surgery results are considered permanent. However, a person’s eye can change throughout life. Because vision can change dramatically during the adolescent years, laser eye surgery is not recommended for anyone under the age of 18.
Those who are pregnant or nursing. Hormone fluctuations during pregnancy and nursing can cause changes to a woman’s vision and corrective prescription. Mothers considering laser eye surgery should wait 3-6 months or longer after weaning to allow their prescription to stabilize.
Those who are taking certain prescription drugs. Some prescription drugs can interfere with laser eye surgery results. For example, some steroids may delay healing and decrease optimal results. Acne medications can cause significant dry eye which can increase the chance of corneal scarring after laser eye surgery.
Those whose vision is not stable. If your prescription is fluctuating, you will not be considered a good candidate for laser eye surgery. Most doctors prefer your prescription to be stable for 1-2 years. Prescriptions can fluctuate for a variety of reasons.
- Contact lens wear, diabetic blood sugar changes and normal aging changes can cause your prescription to change over time.
- Those who are not in good general health.
- Certain medical conditions can affect the way your body heals after surgery.
- Patients with autoimmune diseases are not good candidates for laser eye surgery.
Many autoimmune conditions cause dry eye syndrome. A dry eye may not heal well and has a higher risk of post-surgery infection. Other conditions such as diabetes, rheumatoid arthritis, lupus, glaucoma or cataracts often affect results. Those who have dry eye syndrome.
- A person with dry eyes has an increased risk for significant post-surgery discomfort and a possible worsening of dry eye symptoms.
- Having dry eyes can also delay proper healing.
- Some people with dry eye symptoms can find relief through various treatments.
- Sometimes patients are placed on special dry eye medications before laser eye surgery.
Certain procedures, such as punctal occlusion, may be performed to help the dry eye condition and minimize unwanted symptoms. Those who have unrealistic expectations. If you expect perfection, laser eye surgery may not be for you. Every patient heals differently after surgery.
- After undergoing laser eye surgery there is always a possibility that you may need to wear reading glasses or corrective lenses for at least some activities.
- While laser eye surgery is an excellent vision correction procedure for many people, it is not for everyone.
- To find out if laser eye surgery is suitable for you, schedule a consultation with Our Doctors in Cheasapeke, Virginia Beach.

Can your eyes be too bad for laser
Get Clear Vision – So what prescription is too high for LASIK? Many eye doctors will set their limits to +6 for farsightedness, -12 for nearsightedness, and 6 diopters for astigmatism. But there are other factors that can make some patients good for LASIK while others are disqualified from the procedure.
If you’re interested in LASIK, then the best thing you can do is speak to a medical professional. They can discuss your health and family history, as well as perform a thorough exam. From there, you can find out what the best step forward is. Do you want to find out if you’re a good candidate for LASIK? Then with us.
We’ve been providing a large part of Kentucky with comprehensive eye care since 1970. : What Prescription Is Too High for LASIK? A Simple Answer
Can your eyes be too bad for laser eye surgery?
Yes, your vision can be potentially too bad for LASIK. LASIK is available to a variety of patients, but patients will generally qualify for treatment if their vision falls between -0.5 D to -8.0 D myopia. The maximum prescription for treatment for patients with moderate to severe myopia is around -8.0 D.
How many times has laser eye surgery gone wrong
How To Reduce The Risks of LASIK? – Overall, the risk of a complication requiring further treatment, by laser or any other technique, is approximately 1 in 1000, and where there is no significant visual loss. The chance of a more serious complication which would affect vision in one eye or the other, or both, is 1 in 10,000,
At what age is it too late to get laser eye surgery?
Some people assume there is an age limit to having laser eye surgery, over say the age of 50, but your suitability depends on your refraction (the strength of your glasses or contact lenses), your eye surface health, the shape of your corneas, and the clarity of your natural lens inside the eye.
- Our vision naturally changes as we get older The natural lens inside the eye is flexible and changes its curved shape to focus on objects that are nearby or at a distance.
- It sits just behind the pupil and helps to focus light on retina at the back of the eye.
- As you get older the lens gets stiffer and loses some of its focusing power.
People with good vision then find they need reading glasses. In some cases laser vision can treat this and in other cases it may well be better to have lens surgery to have the natural lenses removed and replaced with multifocal lens implants. Clarity of the natural lens (cataracts) The lens also loses clarity with age and when the lens gets misty enough to affect vision, it is called a cataract.
- Most people with cataracts will need surgery to replace the misty natural lens with an implant.
- The focusing power of the implant can be chosen so as to correct your distance vision – effectively building your spectacle prescription into your eyes.
- Multifocal implants can also be used to correct both distance and near vision.
Modern cataract surgery is so successful at correcting the need for glasses, many patients opt to have it before their lenses have become misty enough to affect visual quality. This is called refractive lens exchange (RLE), The older you get, the more likely it is that this option will be preferred over laser vision correction.
Modern laser systems are safe and effective Many patients over the age of 50 do not have cataracts and still have at least some focusing power from the natural lens. If this is the case, during your examination with us at Moorfields Private, we are more likely to recommend laser vision correction. Provided the eye surface health is good, there is no age limit on when laser vision correction can be performed successfully, and we often use it to fine-tune the results of RLE.
People over the age of 50 are more likely to be symptomatic if they are long-sighted (hyperopia), and may find that they need glasses for distance vision as well as reading. In this group, modern laser systems are very safe and effective. Vision from the two eyes can be blended together – targeting better near vision in one eye and better distance in the other – to provide good vision over the full range.
You are never too old to have vision correction surgery Many patients choose to have treatment to free them up for travel or outdoor exercise once they retire. The treatment which is most suitable for your eyes is best determined by the right tests and an expert opinion from your operating surgeon. One of the main benefits that distinguish Moorfields Private from other clinics is that you will be seen at every visit by the surgeon in charge of your care.
This level of continuity helps to ensure the right decisions are made at every stage and you get the best results from your treatment.
Do you still need glasses after laser eye surgery?
While the majority of people who undergo LASIK treatment will not need glasses after surgery, some individuals may still require glasses for optimum vision. LASIK also does not protect against age-related vision changes, so it’s likely you may eventually need reading glasses.
What is the best age to get Lasik eye surgery?
LASIK: 25-40 – Generally speaking, most LASIK eye surgeons agree on 25-40 as the ideal age range for LASIK eye surgery candidacy for a few reasons. By the age of 25, eyeglasses and contact lens prescriptions have most likely stabilized. A stable prescription is one of the hallmarks of a good LASIK candidate. Before the age of 25, your prescription may still be changing.
Does laser eye work for everyone?
If you have an above average level of myopia or hyperopia you may not be eligible for LASIK. For myopia (near-sightedness), this would fall between -8 and -20 dioptres. Hyperopia (far-sightedness) above +5 is not ideal for LASIK. LASIK is possible for 99% of people with otherwise healthy eyes.
Why isn t LASIK more popular
The Downfall of LASIK’s Popularity – There is no doubt that we are witnessing the crumble of the LASIK surgery empire. According to Market Scope, a leading market researcher in the field of eye care, has found that LASIK surgeries have dropped more than 50 percent between 2007 and 2015.
- In less than 10 years, this supposedly revolutionary corrective surgery is beginning to slip, a trend that has continued in the last five years.
- Eye care experts don’t have a concrete reason for this.
- LASIK surgeons blame the economy, citing that it has yet to recover from the recession, meaning that fewer people can afford the surgery.
While this may be true, other ophthalmologists claim that the millennial generation is choosing different ways to care for their eyes, if they choose to care for their eyes at all. The millennial generation is still a young one and perhaps the realities of caring for aging eyes has not yet hit them, which could explain their lack of interest in LASIK surgery.
What eye problems can lead to surgery
Eye Surgery – Types, Recovery, & Risks | Made for This Moment Eye surgery is used to treat a variety of conditions, including cataracts, glaucoma, detached retinas, retinal tears, diabetic retinopathy, and nearsightedness or farsightedness.
What can go wrong eye surgery?
Risk Factors – Risk factors associated with worse visual outcomes
- Age-related macular degeneration
- Diabetic retinopathy
- Corneal opacity/pathology
- Older age
- Female sex
- Previous vitrectomy
- Previous retinal detachment
- Alpha blockade
- Intraoperative complications
Complications can range from immediate to delayed complications following the procedure. Some immediate complications are a result of having the surgical procedure. These include discomfort, bruising and swelling of the eyelid, increased intraocular pressure, and allergic reaction to the steroid or antibiotic drop.
These complications are monitored over time following surgery. If there is progression to pain, decrease in vision, or any discharge from the eye, patients are advised to seek medical attention. A long-term consequence of cataract surgery is posterior capsular opacification (PCO). PCO is the most common complication of cataract surgery.
PCO can begin to form at any point following cataract surgery. Modern cataract surgery creates a capsular bag that contains part of the anterior, the entire posterior capsule, and the implanted, intraocular lens. In the remaining anterior capsule, epithelial cells remain despite the surgical trauma.
These epithelial cells will begin to settle on the anterior capsule and colonize the posterior capsule. The cells will continue to divide and begin to alter the lens matrix and therefore the refraction of the lens. PCO can successfully be treated with YAG laser capsulotomy, which will provide almost immediate improvement in vision.
Complications discussed below can be immediate complications but are more severe than those previously mentioned.
How long does LASIK last?
How Long Does LASIK Eye Surgery Last? – The question, ” How long does LASIK last?” doesn’t have a definite answer. While the effects of LASIK surgery are permanent, the benefits can decrease over time. For most patients, the results of this surgery will last a lifetime. About 10-12% of patients nationwide will need an enhancement surgery because of anatomical changes to the eye/eyes.
What Cannot be fixed with LASIK?
Cataracts – Cataracts are typically found in people who are over the age of 65 and make your vision cloudy or foggy. Cataracts are a disease of the lens, and as such, LASIK will not correct them. If you have a cataract, you should be monitored by a cataract specialist, such as Dr.
What part of the eye is most vulnerable to laser damage
Laser effects on the eye – The unprotected human eye is extremely sensitive to laser radiation and can be permanently damaged from direct or reflected beams. Due to tissue characteristics, the area of the eye damaged by laser energy is dependent upon the wavelength of the incident laser beam. The retina, cornea, and lens are the areas most commonly damaged.
Retina: Laser light in the visible to near-infrared spectrum can cause damage to the retina. These wavelengths are also known as the “retinal hazard region.”
Visible and near-infrared (400 – 1400 nanometer or nm) laser light pose a critical hazard on the retina. Infrared A is transmitted by the cornea to the lens of the eye which narrowly focuses it on the retina, concentrating the radiant exposure of the laser by up to 100,000 times. Since the tissue structures of the retina are unable to undergo any repair, lesions caused by the focusing of visible or near-infrared light on the retina may be permanent. The most critical area of the retina is the central portion, the macula, and the fovea.
Cornea and lens: Laser light in the ultraviolet or far-infrared spectrum can cause damage to the cornea or the lens.
Ultraviolet (180 nm to 400 nm): Photochemical damage is caused by the absorption of UV light by selective sensitive portions of cells of the cornea. Many proteins and other molecules (DNA, RNA) absorb UV light and are “denatured” by the radiation. Excessive exposure to UV light can cause photophobia, redness of the eye, tearing, discharge, stromal haze, etc. These adverse effects are usually delayed for several hours but will occur within 24 hours. The lens principally absorbs UVA (315-400 nm). The lens is particularly sensitive to the 300 nm wavelength. XeCl eximer lasers operating at 308 nm can cause cataract with an acute exposure. Far infrared (1400 nm to 1 mm; CO2 lasers, 10600 nm): Thermal damage is caused by the heating of the tears and tissue water of the cornea by the infrared light. Excessive exposure to infrared radiation results in a loss of transparency of the cornea or surface irregularities.
Does closing eyes protect from laser?
Laser Mechanisms of Injury – Rarely, ocular injuries can occur. A misdirected laser beam towards the eye or any reflective surface can penetrate the eye even when the lids are closed. The thickness of eyelids is not sufficient to protect the eye from injury from laser beam exposure, since the light can easily penetrate through.
- The mechanism of damage to the eye depends on the wavelength of laser used.
- Short wavelength lasers produce photothermal damage via photocoagulation, while long wavelength lasers can additionally instigate photomechanical damage via photodisruption.
- Short wavelength lasers include potassium titanyl phosphate (KTP) and pulsed dye lasers (PDL).
KTP and PDL lasers are commonly used to treat facial redness and reduce acne scars. They can cause tissue to generate enough heat to denature proteins. When directed at the eye, retinal temperature can be increased by as much as 40°-60°C, causing thermal damage.
- Long wavelength lasers include diode, Nd:YAG lasers, and alexandrite lasers, which are commonly used in hair removal procedures.
- In addition to causing photothermal damage, they can cause an explosive acoustic shock, where sheared fragments of the chromophore can perforate surrounding tissue, causing mechanical damage.
The most frequently reported laser causing ocular damage is the carbon dioxide laser, which has a very high wavelength of 10,600 nm. Carbon dioxide is followed by alexandrite, diode, and Nd:YAG in most common lasers implicated in ocular injury. Notably, these are all long wavelength lasers that cause both photothermal and photomechanical damage to the eye.
Lack of adherence to safety precautions and accidental misdirecting of lasers can cause ocular injury during periorbital laser treatments. In a study of 40 patients with ocular injury, only 15% were wearing protective eyewear. Providers often ask patients to remove protective eyewear during eyebrow epilation or eyeliner tattoo removal, adding to the risk of laser exposure to the eye.
especially high. Furthermore, Bell’s phenomenon (where the eye naturally rolls upward upon eyelid closure) increases the risk of damage to the iris by bringing anterior eye structures closer to the laser’s radiation range.
What percent of laser eye surgery goes wrong?
How Safe is LASIK? – All surgeries carry some risk of complications and side effects, but LASIK is generally considered a safe procedure with a low complication rate.3 In fact, LASIK is one of the safest elective surgical procedures available today, with a complication rate estimated to be less than 1%.
What can happen if laser eye surgery goes wrong?
What will happen if something goes wrong with my Laser Eye Surgery? Laser eye surgery is a very technical operation and requires years of training to learn how to perform the surgery. As with all surgical procedures there is a risk of problems developing both during and after the operation.
The likely hood that you will develop any problems is fairly rare. Even though problems are rare, you should understand that these can happen to you, so that you can be fully prepared should they arise. The major problems following laser eye surgery are infection,, irritation and night time symptoms such as and, which all tend to subside over time.
There is also the risk of your vision being under or over corrected following the procedure, meaning you will still be required to wear glasses or contact lenses. This will unfortunately require further surgery to correct. To help prevent you experiencing these problems, your surgeon will help you decide which operation is the best and most suited to you.
- If something does go wrong with your eye surgery, if it is the fault of the surgeon or equipment, it is likely that you will be eligible to have the operation re-done.
- This is not the case if the procedure goes well, yet you find you need further surgery to correct your vision.
- This is called and you will usually have to pay for it, unless it is included in the aftercare package.
If something does go wrong, your surgeon will explain to you what has happened and why, followed by what they can do to make it better. If at any time you feel unsatisfied by your care you can complain, either directly to the, or to the, : What will happen if something goes wrong with my Laser Eye Surgery?
Is LASIK worth it over 40?
Is It Worth Getting LASIK After 40 or even 50? – There is no age cut-off when it comes to having LASIK surgery. As long as you meet the criteria for eligibility, the procedure is safe. Even those over 40 or 50 years old can benefit from the procedure, which is an investment that is worth it compared to wearing glasses or contacts for the rest of their lives.
What is the risk of laser eye surgery going wrong
How To Reduce The Risks of LASIK? – Overall, the risk of a complication requiring further treatment, by laser or any other technique, is approximately 1 in 1000, and where there is no significant visual loss. The chance of a more serious complication which would affect vision in one eye or the other, or both, is 1 in 10,000,
At what point should you get laser eye surgery
LASIK: 18-24 – The FDA approved LASIK for those 18 and over, but it might be best to wait a few more years. Until the age of 24, our eyesight continues to change, so it is not often that a LASIK eye surgeon will recommend the procedure for those under the age of 25 for the general public. Those in the military, law enforcement, and professional athletes may be given special consideration.
Will you ever need glasses after laser eye surgery?
While the majority of people who undergo LASIK treatment will not need glasses after surgery, some individuals may still require glasses for optimum vision. LASIK also does not protect against age-related vision changes, so it’s likely you may eventually need reading glasses.
