No, LASIK cannot directly fix crossed eyes, also known as strabismus.
LASIK (Laser-Assisted in Situ Keratomileusis) is a procedure designed to correct refractive vision errors such as nearsightedness, farsightedness, and astigmatism by reshaping the cornea.
Strabismus, in contrast, is a condition where the eyes are misaligned and do not work in tandem. It is primarily a neurological or muscular issue, rather than a problem with the shape or refractive errors of the cornea.
That said, there are instances where LASIK may play an indirect role in improving symptoms associated with strabismus or bettering the patient’s overall quality of life. Below, we’ll explore the details of how strabismus is treated, what LASIK can (and cannot) do, and other potential interventions that can help address misaligned eyes.
Understanding Strabismus
What is Strabismus?
Strabismus, commonly referred to as “crossed eyes” or “wandering eyes,” occurs when the eyes fail to align properly. One eye may focus straight ahead, while the other deviates inward, outward, upward, or downward. This condition can happen intermittently or be constant. Strabismus often develops in childhood, but it can also occur later in life due to injuries, trauma, or other neurological issues.
Symptoms of Strabismus
Key symptoms of strabismus include:
- Misaligned eyes (where one or both eyes are not looking in the same direction)
- Double vision (diplopia)
- Poor depth perception
- Difficulty focusing or reading
- Eye strain or fatigue
- Head tilting or turning to improve vision clarity
Causes of Strabismus
Strabismus is generally the result of issues in the eye muscles, nerve control, or the brain’s coordination of the two eyes. Some common causes include:
- Congenital strabismus: Present from birth or early infancy.
- Refractive errors: Significant differences in vision between the two eyes can sometimes cause strain, leading to intermittent misalignment.
- Neurological conditions: Disorders such as cerebral palsy, Down syndrome, or stroke can result in weakened or uncoordinated eye muscles.
- Trauma or injury: Damage to the brain or eye muscles can disrupt alignment.
- Imbalances in facial or orbital structure: Deformities or injuries to the face or eye can also play a role.
What LASIK Treats
LASIK is a refractive laser procedure performed to correct common vision problems like:
- Myopia (nearsightedness): The cornea is too steep, causing nearby objects to appear clear, but distant objects are blurry.
- Hyperopia (farsightedness): The cornea is too flat, making nearby objects blurry while distant ones seem clearer.
- Astigmatism: The cornea is irregularly shaped, blurring vision at all distances.
By reshaping the cornea, LASIK helps light focus correctly on the retina, leading to clearer vision. However, LASIK primarily addresses optical issues with how light enters the eye and does not alter the functioning of eye muscles or the neurological pathways associated with eye movement.
Why LASIK Can’t Directly Fix Crossed Eyes
Strabismus is not inherently related to the shape of your cornea or your prescription for glasses. Instead, it is a problem involving the coordination and movement of your eye muscles. LASIK has no effect on these muscles or the nervous system responsible for controlling eye alignment. Hence, while LASIK can help you see more clearly, it cannot straighten misaligned eyes or fix the underlying causes of strabismus.
When Can LASIK Be Indirectly Beneficial for Strabismus?
Although LASIK cannot directly treat strabismus, it may benefit some individuals with the condition in specific scenarios:
1. Reducing Dependence on Corrective Lenses:
People with strabismus caused by significant refractive errors (such as a strong prescription for myopia or astigmatism) may experience less eye strain after LASIK. Correcting their vision with LASIK can improve overall comfort and visual clarity, potentially reducing symptoms like double vision in cases of mild or intermittent strabismus.
2. Improving Self-Confidence:
For adults with strabismus who wear thick glasses, LASIK can remove the need for spectacles. While it won’t correct the misalignment, clearer vision without glasses may provide a significant confidence boost and improve the overall quality of life.
3. Supporting Therapeutic Interventions:
LASIK may complement other forms of treatments used for strabismus, such as prism glasses, vision therapy, or even surgical intervention. By resolving refractive errors, LASIK ensures that the patient’s corrective needs are met, allowing specialists to focus solely on addressing alignment issues.
Effective Treatments for Strabismus
If LASIK isn’t the solution for crossed eyes, what options are available? Treatments for strabismus depend on the severity, underlying cause, and whether the condition developed in childhood or adulthood. Here are the most common options:
1. Glasses or Prism Lenses
Some cases of strabismus caused by significant refractive errors can be corrected with glasses. Prism lenses are designed to bend light, helping to reduce double vision and improve alignment.
2. Eye Patching (Occlusion Therapy)
Eye patching is often used in children, especially those with “lazy eye” (amblyopia) in conjunction with strabismus. Covering the stronger eye forces the weaker eye to work harder, promoting improvement in alignment and vision strength.
3. Vision Therapy
Vision therapy involves exercises designed to strengthen the coordination and function of the eyes. This approach is particularly effective for those with convergence insufficiency or intermittent strabismus. Therapy can be performed in a clinic or at home with guided instructions.
4. Botox (Botulinum Toxin) Therapy
For some types of strabismus, Botox can be injected into the eye muscles to temporarily paralyse overactive muscles. This allows the weaker muscles to strengthen and improve alignment over time.
5. Strabismus Surgery
Surgery is an effective option for correcting more pronounced cases of strabismus. It involves shortening, lengthening, or repositioning the eye muscles to achieve proper alignment. It’s worth noting that while surgery improves the symmetry of the eyes, it doesn’t guarantee perfect binocular vision.
6. Lifestyle Recommendations
Managing strabismus often includes reducing eye strain. Protect your vision by adhering to the “20-20-20” rule: every 20 minutes of screen use, focus on an object 20 feet away for 20 seconds. Ensure proper lighting when reading, and prioritize regular eye examinations, as they play a vital role in maintaining eye health.
Combined Approaches
Many patients benefit from a combination of methods to manage strabismus effectively. Vision therapy may be combined with prism glasses, surgical intervention may follow Botox treatments, and so on, depending on individual circumstances.
Final Thoughts on LASIK and Strabismus
While LASIK cannot fix crossed eyes, it can improve other aspects of vision that may indirectly complement certain strabismus management strategies. Understanding the nature of your condition and consulting with an ophthalmologist or strabismus specialist can help determine the most suitable path forward.
If clearer vision is your priority, LASIK remains an excellent choice for addressing refractive errors. Want to learn more about improving your vision or managing strabismus? Schedule a consultation with your eye care provider today!
