Have you been contemplating LASIK eye surgery but are unsure if you would be the right candidate for it? It’s common to feel lost in the maze of information out there, especially when you’re seeking permanent solutions to your vision troubles. But one thing is for sure, not everyone is a suitable candidate for LASIK.
For starters, if you’re pregnant, LASIK isn’t recommended as the hormonal changes during pregnancy can affect your eyes. Similarly, anyone with a history of autoimmune disorders or eye diseases, such as glaucoma or keratoconus, are also not ideal candidates for LASIK. These conditions can complicate the LASIK process and even lead to irreversible vision damage.
Additionally, those who have thin corneas or have undergone previous eye surgeries are often not considered good candidates for LASIK. This is because LASIK requires the removal of a small portion of the cornea to reshape it, and thin corneas or previous surgeries can make the procedure more complicated. Remember, your eye surgeon can guide you appropriately on whether LASIK is right for you or not.
Who is not a good candidate for LASIK?
While LASIK can provide life-changing benefits for many people, it’s important to note that it may not be suitable for everyone. The following are some of the most common reasons why you may not be a good candidate for LASIK:
- You are younger than 18 years old: LASIK is only FDA approved for individuals who are 18 years or older. This is because your eyes may still be changing and developing before that age.
- You are pregnant or breastfeeding: Hormonal changes during pregnancy and lactation can affect the stability of your vision. To ensure your safety and the safety of your child, it’s best to wait until after you have finished breastfeeding to undergo LASIK.
- You have uncontrolled autoimmune disorders: Certain autoimmune disorders, such as rheumatoid arthritis and lupus, can affect your eye health and your body’s ability to heal after surgery. If you have an autoimmune disorder that is not well-controlled, you may be at a higher risk of complications following LASIK.
If you fall into any of these categories, it’s important to discuss your options with your eye doctor. They can help you determine the best course of action to achieve your visual goals.
Common vision problems that LASIK cannot correct
While LASIK is a highly effective and popular vision correction procedure, not everyone is an ideal candidate for this surgery. There are certain types of vision problems that LASIK cannot correct, and patients with these issues may need to consider other treatment options.
One of the most common types of vision problems that LASIK cannot correct is presbyopia. As individuals age, their eyes begin to lose the ability to focus on objects up close, making it difficult to read or perform other tasks that require sharp, detailed vision. LASIK surgery reshapes the cornea to improve distance vision but does not address the loss of near vision associated with presbyopia. Patients with this condition may instead consider options like reading glasses, bifocal lenses, or monovision LASIK.
- Another condition that LASIK cannot correct is severe levels of myopia (nearsightedness). LASIK can typically treat up to -11.00 D of myopia, but beyond that limit, the risks of complications increase significantly. Patients with higher levels of myopia may need to consider alternative treatments like implantable contact lenses or refractive lens exchange.
- Similarly, patients with high levels of hyperopia (farsightedness) may also not be good candidates for LASIK. Depending on the severity of the condition, patients with hyperopia may have limited surgical options and may need to rely on corrective lenses or other treatments to improve their vision.
- Corneal irregularities, such as keratoconus, can also impact a patient’s candidacy for LASIK. These conditions can cause the cornea to bulge or become thin and weak, making it difficult for the laser to create a precise and stable corneal flap. Patients with keratoconus or other corneal abnormalities may need to consider other surgical options like photorefractive keratectomy (PRK), corneal collagen cross-linking (CXL), or implantable collamer lenses (ICL).
Treatment alternatives for patients with these conditions
While LASIK may not be the best option for patients with certain vision problems, there are a variety of other treatments available that can help improve their vision and quality of life. Depending on the specific condition and its severity, patients may benefit from options like:
- PRK: A laser vision correction procedure that does not require a corneal flap and is performed directly on the surface of the cornea. PRK may be a good choice for patients with thin corneas or corneal irregularities.
- CXL: A non-surgical treatment that uses riboflavin drops and UV light to strengthen the cornea and slow or halt the progression of conditions like keratoconus or corneal ectasia.
- ICL: An implantable lens that is placed behind the iris to correct vision without altering the shape of the cornea. ICLs can be a good alternative for patients with high levels of myopia or hyperopia, or those with thin corneas.
- Bifocal or multifocal contact lenses: Soft contact lenses that provide correction for both distance and near vision, making them a good option for patients with presbyopia.
- Reading glasses: Simple, non-invasive corrective lenses that can help patients with presbyopia see clearly up close.
Conclusion
While LASIK is a highly effective vision correction procedure for many patients, it is not always the best option for everyone. Patients with certain vision problems, such as presbyopia, severe myopia or hyperopia, or corneal irregularities, may need to consider alternative treatments to achieve the best possible outcome. By working with an experienced ophthalmologist or eye surgeon, patients can explore their options and make an informed decision about the best course of treatment for their specific needs.
| Vision Problem | LASIK Candidacy | Alternative Treatments |
|---|---|---|
| Presbyopia | Poor | Reading glasses, bifocal lenses, monovision LASIK |
| Severe myopia | Poor | Implantable contact lenses, refractive lens exchange |
| High hyperopia | Poor | Corrective lenses, surgical implants |
| Corneal Irregularities | Poor | PRK, CXL, ICL |
Overall, the key to a successful vision correction treatment is a thorough evaluation of each patient’s vision, eye health, and individual needs. By working closely with a qualified eye doctor, patients can determine the best course of treatment and achieve their goals for clear, comfortable, and confident vision.
Age restrictions for LASIK surgery
While LASIK surgery has gained popularity over the years as a safe and effective way to correct various visual impairments, there are certain restrictions pertaining to the age of the patient. While some patients may be eligible for LASIK at a younger age, there are some who may have to wait till they are older to undergo the procedure successfully.
- Minimum Age Requirement: In the United States, the Food and Drug Administration (FDA) has approved LASIK surgeries for patients who are at least 18 years of age or older. This is because the eyes continue to develop and change until the age of 18. Therefore, LASIK surgery before that age could result in vision changes that can cause nearsightedness, farsightedness, or astigmatism.
- Maximum Age Limit: While there is no maximum age limit for LASIK surgery, there are certain age-related eye conditions, such as presbyopia, that may make the surgery less effective. Presbyopia typically develops after the age of 40 and is a natural aging process that causes the eyes to lose their ability to focus on close objects. This condition can be corrected with LASIK, but patients who have presbyopia may still need to wear reading glasses to read small print. Additionally, some older patients may not be eligible for LASIK if they have cataracts or other age-related eye diseases.
- Pregnancy: Women who are pregnant or breastfeeding are not suitable candidates for LASIK surgery. Hormonal changes during pregnancy and breastfeeding can cause fluctuations in visual acuity that may make surgery less effective or even dangerous. It is recommended that women wait until several months after delivering their baby or weaning from breastfeeding before undergoing LASIK surgery.
In conclusion, age is an important factor to consider when determining if LASIK surgery is right for you. While LASIK can correct many visual impairments, it may not be advisable for certain age groups or conditions. Consult with your eye doctor to determine if LASIK is a suitable option for you.
Medical conditions that may disqualify a person from LASIK surgery
While LASIK surgery is a safe and effective procedure for many people, not everyone is a good candidate. There are certain medical conditions that may disqualify a person from undergoing LASIK surgery. It is important to discuss any existing medical conditions with your ophthalmologist before considering LASIK.
- Pregnancy: Pregnancy can cause temporary changes in vision, and LASIK is not recommended for pregnant women due to the potential risks to the developing fetus.
- Autoimmune disorders: Autoimmune disorders such as rheumatoid arthritis, lupus, and multiple sclerosis can affect the healing process and increase the risk of complications during and after LASIK surgery.
- Diabetes: People with diabetes tend to have slower healing times, and LASIK can exacerbate existing eye problems associated with diabetes.
In addition to the medical conditions listed above, there are other factors that may disqualify a person from LASIK surgery, such as the severity of their vision problems and age. LASIK may not be appropriate for people who have very high prescriptions, thin corneas, or who are over the age of 60.
It is also important to note that certain medications can impact the healing process after LASIK surgery, so it is important to inform your ophthalmologist of any medications you are taking. Your ophthalmologist will perform a thorough evaluation to determine if LASIK is a safe and appropriate option for you.
| Medical Condition | Description | Disqualification from LASIK? |
|---|---|---|
| Pregnancy | Pregnancy can cause temporary changes in vision. | Yes |
| Autoimmune disorders | Autoimmune disorders can affect the healing process and increase the risk of complications during and after LASIK surgery. | Yes |
| Diabetes | People with diabetes tend to have slower healing times, and LASIK can exacerbate existing eye problems associated with diabetes. | Yes |
If you have any questions or concerns about whether LASIK is right for you, schedule a consultation with an experienced ophthalmologist who can evaluate your individual needs and help you make an informed decision.
Medications that may affect LASIK eligibility
One of the most important factors in determining whether a person is a good candidate for LASIK is their overall health and medical history. Certain medications can affect the eyes and may disqualify someone from being eligible for LASIK surgery. Let’s take a closer look at some of the medications that may impact LASIK eligibility.
- Accutane: This medication is used to treat severe acne, but it may cause dryness and thinning of the skin, as well as dry eyes. LASIK surgery requires healthy, well-lubricated eyes, so individuals taking Accutane will likely need to wait at least six months after discontinuing the medication before being considered for LASIK.
- Anti-inflammatory drugs: Certain anti-inflammatory medications, such as corticosteroids, can cause elevated intraocular pressure and lead to glaucoma. LASIK candidates taking these medications may need to switch to an alternative treatment or wait until their condition is under control before undergoing surgery.
- Immunosuppressants: Medications that suppress the immune system, such as those used in organ transplant patients, can increase the risk of infection after LASIK surgery. These individuals may need to wait until their immune system function has stabilized before undergoing the procedure.
It’s important to note that this list is not exhaustive, and individuals considering LASIK should always disclose any medications they are currently taking to their eye doctor during their consultation. Based on the patient’s individual medical history and the specific medication in question, the surgeon can make an informed decision about whether LASIK surgery is safe and appropriate.
In addition to medications, other factors such as chronic dry eye, corneal disease, and autoimmune disorders may also impact LASIK eligibility. It’s crucial for prospective patients to undergo a thorough eye exam and consultation with a qualified LASIK surgeon to determine their candidacy for the procedure.
Pregnancy and LASIK Surgery
One group of people who might be excluded from LASIK surgery are pregnant women. The primary concern with LASIK during pregnancy is the potential for hormonal changes to slightly alter the shape of the cornea, which can affect the outcome of the surgery. A pregnancy can also put extra strain on a woman’s eyes and cause a transient change in her vision, which can decrease the stability of LASIK measurements.
While there is no strong evidence that LASIK would have harmful effects on the baby, it is still considered a purely elective procedure and shouldn’t take priority over the health of the mother and her baby. LASIK is a quick procedure, but it still requires anesthesia and an extensive amount of follow-up care, which is not ideal for women who are pregnant or in the early stages of breastfeeding.
If you are considering LASIK surgery, the American Academy of Ophthalmology recommends waiting until after you have finished having children and completed breastfeeding. This can take several years, but your vision is too important to compromise just to avoid wearing glasses or contact lenses for a short time.
Additional Concerns with LASIK and Pregnancy
- Fluctuations in hormones can cause changes in the corneal shape and thickness, which affects the accuracy of measurements during LASIK evaluation.
- Increased risk of dry eye syndrome, which can worsen with pregnancy and aggravate the postoperative healing process after surgery.
- Antibiotics and other medications used during LASIK may not be safe for the baby during pregnancy or while breastfeeding.
What if I’m Pregnant and Need Vision Correction?
While LASIK is not recommended during pregnancy, there are other alternatives to consider if you need vision correction. One alternative is wearing prescription glasses or contact lenses, which are safe during pregnancy and do not affect the health of the baby.
| Option | Pros | Cons |
|---|---|---|
| Glasses | Safe during pregnancy, can be stylish and affordable, no risk of infection | Can get scratched or broken easily, may slide down nose, peripheral vision can be obstructed |
| Contact Lenses | Safe during pregnancy if used properly, provide better visual acuity than glasses, easier to play sports or be active with | Require more maintenance and care, can cause discomfort, increased risk of infection or irritation if not handled properly |
If you are pregnant or planning a pregnancy, talk to your eye doctor about your vision correction options and what the best course of action is for your individual situation. Remember, your health and the health of your baby always come first.
Dry eye syndrome and LASIK surgery
Dry eye syndrome is a common condition where one doesn’t produce enough tears, or the tears produced are of low quality, making the eyes feel gritty or sore. For people with dry eyes, LASIK surgery might not be the best option. Here’s why:
- During LASIK surgery, a flap is cut into the cornea to reshape it. This flap creation process can disrupt the nerves that control tear production, making the dry eye condition worse.
- After LASIK surgery, the cornea needs to heal, creating a temporary decrease in tear production, which may be challenging for those already suffering from dry eyes.
- Even after LASIK surgery, some patients may experience dry eyes as a side effect.
If you have dry eyes, it’s essential to talk to your ophthalmologist about the available options. They might recommend other vision correction treatments like PRK (photorefractive keratectomy) or LASEK (laser epithelial keratomileusis), which might be a better fit for your condition.
Management of dry eyes before LASIK surgery
If you tend to suffer from dry eyes and are considering LASIK surgery, your ophthalmologist will likely recommend a dry eye evaluation. If you have an underlying dry eye condition, they might suggest a few things before the surgery, such as:
- Artificial tears and lubricating eye drops to promote tear production. These are available in over-the-counter and prescription forms.
- Restasis (cyclosporine), an anti-inflammatory prescription eye drop designed for people with chronic dry eye.
- Conservation measures like avoiding extremely dry environments or minimizing the usage of contact lenses.
The bottom line
If you have dry eyes, LASIK surgery may not be a suitable option for correcting your vision. Consult your ophthalmologist for the available alternatives, and if you’re considering LASIK, discuss the management of dry eyes before the surgery.
| Advantages | Disadvantages |
|---|---|
| Fast recovery and minimal downtime | May worsen an underlying dry eye condition |
| Long-lasting results with high patient satisfaction | Increased risk of dry eyes as a side effect post-surgery |
| Minimally invasive and effective for correcting a range of vision impairments | Not recommended for patients with unstable vision or severe dry eyes |

Corneal thickness and LASIK eligibility
One of the most crucial factors in determining who is not a good candidate for LASIK is corneal thickness. LASIK involves creating a thin flap on the cornea, and then reshaping the underlying tissue with an excimer laser. If the cornea is too thin, there may not be enough tissue to reshape safely, leading to complications such as corneal ectasia. Corneal ectasia is a rare but serious complication that causes progressive thinning and bulging of the cornea, leading to blurry vision and other visual distortions.
It is worth noting that not all LASIK surgeons use the same corneal thickness cutoffs when determining eligibility. Some may use more conservative thresholds than others, and some may recommend alternatives to LASIK surgery, such as photorefractive keratectomy (PRK). Therefore, it is essential to have a detailed consultation with a qualified LASIK surgeon, who will evaluate your individual case and determine your suitability for the procedure.
Factors that affect corneal thickness
- Age: Corneal thickness tends to decrease with age.
- Corneal disease: Certain conditions that affect the cornea, such as keratoconus, can cause the cornea to become thin and weak.
- Genetics: Some people are born with thinner corneas than others.
- Previous eye surgery: If you have had previous surgeries that affect the cornea, such as radial keratotomy (RK) or phototherapeutic keratectomy (PTK), your cornea may be thinner than average.
Corneal thickness measurement
Corneal thickness can be measured using a technique called pachymetry. During this test, a small device is placed on the cornea to measure its thickness. Pachymetry is a painless and non-invasive procedure that typically takes just a few minutes to complete.
Corneal thickness cutoffs for LASIK eligibility
The corneal thickness cutoffs for LASIK eligibility vary depending on the surgeon and the technology used in the procedure. In general, however, a corneal thickness of at least 500 microns is considered the minimum safe thickness for LASIK. Some surgeons may use more conservative cutoffs, such as 550 microns or even 600 microns, to minimize the risk of complications.
| Corneal thickness (microns) | LASIK eligibility |
|---|---|
| Less than 500 | Not a good candidate for LASIK |
| 500-550 | Candidate for LASIK, but may require a more conservative treatment plan |
| More than 550 | Likely a good candidate for LASIK |
It is important to note that corneal thickness is just one of several factors that determine LASIK eligibility. A qualified LASIK surgeon will take into account your overall eye health, age, refractive error, and other factors when determining whether LASIK is right for you.
LASIK Complications and Risks
For many prospective LASIK patients, the potential risks and complications associated with the procedure may make it a less desirable option. There are several factors that can make an individual a poor candidate for LASIK, including:
- Poor overall health
- Pregnancy or breastfeeding
- Thin corneas
- Large pupils
- Severe nearsightedness, farsightedness, or astigmatism
- Previous eye surgery or injury
- A history of dry eye syndrome or other eye conditions
- Age (typically under 18)
- Participation in contact sports or activities that may increase the risk of eye injury
While many patients who undergo LASIK achieve improved vision and are satisfied with their results, there are some potential complications and risks associated with the procedure. These include:
- Temporary discomfort, such as dryness, itchiness, and sensitivity to light
- Halos, glare, or double vision
- Undercorrection or overcorrection, which may require further procedures
- Infection or inflammation
- Loss of vision
To better understand the risks and potential complications associated with LASIK, it may be helpful to review the table below, which highlights some of the possible side effects and their associated frequencies:
| Side Effect | Frequency |
|---|---|
| Discomfort or pain | 90% |
| Halos, glare, or double vision | Less than 5% |
| Dry eye syndrome | Less than 5% |
| Undercorrection or overcorrection | Less than 5% |
| Infection or inflammation | Less than 1% |
| Loss of vision | Less than 1% |
It’s important to note that while these risks and complications are possible, they are relatively rare, and most patients experience improved vision following LASIK without any significant issues. However, it’s essential to discuss any concerns or questions you may have with a qualified LASIK surgeon before proceeding with the procedure.
Alternative vision correction options for individuals who are not good candidates for LASIK
While LASIK is an effective and popular form of vision correction surgery, not everyone is a good candidate for the procedure. Certain conditions or risk factors may disqualify someone from being able to have LASIK, such as extreme nearsightedness or thin corneas. However, even for those who cannot have LASIK, there are alternative vision correction options available.
- PRK: Photo Refractive Keratectomy, or PRK, is a similar laser eye surgery to LASIK. However, instead of creating a flap in the cornea, the top layer of the cornea is removed entirely. This allows for correction of nearsightedness, farsightedness, and astigmatism without requiring a thick cornea.
- Phakic Intraocular Lenses: For individuals with extremely high levels of nearsightedness, phakic intraocular lenses may be a better alternative. These lenses are implanted inside the eye, in front of the natural lens. This allows for clear vision without the need for glasses or contacts.
- Orthokeratology: Orthokeratology, or ortho-k, involves wearing special contact lenses overnight to reshape the cornea and improve vision. This option is often favored by individuals who want to avoid surgery altogether.
It’s important to discuss all vision correction options with an eye doctor to determine the best course of action for your individual needs and health.
Additionally, for individuals who are not good candidates for any type of vision correction surgery, there are other non-surgical options available:
- Glasses: While not a permanent solution, glasses can effectively correct vision without surgery. They also come in a variety of styles and can be a fashion statement for some individuals.
- Contact lenses: Like glasses, contact lenses can correct vision without surgery. They are also available in a variety of types, including daily disposable, extended wear, and rigid gas permeable lenses.
- Low-vision aids: For individuals with severe vision loss or blindness, low-vision aids such as magnifiers, telescopes, or electronic devices can help them see more clearly and perform daily tasks.
Ultimately, the best option for vision correction depends on a variety of factors including eye health, personal preferences, and lifestyle. Consult with an eye doctor to determine which option is right for you.
| Option | Description |
|---|---|
| PRK | A similar laser eye surgery to LASIK, but without the need for a thick cornea |
| Phakic Intraocular Lenses | Lenses implanted inside the eye for individuals with extreme nearsightedness |
| Orthokeratology | Contact lenses worn overnight to reshape the cornea and improve vision |
For those not eligible for surgery, there are other alternatives such as glasses, contacts, and low-vision aids.
