In the realm of vision correction surgery, SMILE (Small Incision Lenticule Extraction) has emerged as a groundbreaking procedure, promising clearer vision and reduced reliance on glasses or contact lenses. However, like any surgical intervention, SMILE surgery may occasionally be accompanied by a rare but noteworthy side effect – double vision, medically called diplopia.
In this comprehensive guide, we will explore the phenomenon of double vision after SMILE surgery, shedding light on its causes, symptoms, duration, and potential solutions. We’ll equip you with the knowledge to navigate this post-operative phase and understand when to seek expert help.
Understanding Double Vision
Double vision/ Diplopia post-SMILE surgery is a rare occurrence, but when it does manifest, it can be a cause for concern and confusion.
Essentially, double vision happens when each eye sends slightly different images of the same object to the brain, making it difficult for the brain to merge them into one cohesive picture. This results in seeing double, with a “ghost image” alongside the main object.
The severity of double vision can vary, ranging from faint shadows that seem to trail the object’s movement to completely separate images of the same object.
Causes of Double Vision After SMILE Surgery
Double vision after SMILE surgery can be attributed to various factors:
- Corneal healing:
During SMILE, a lenticule is created and removed from the cornea, temporarily disrupting its shape. This causes light rays to scatter and focus imperfectly, leading to temporary blurry vision and, in some cases, double vision. Additionally, the healing process can sometimes result in a subtle misalignment between the image receptors. This misalignment presents a challenge for the brain as it strives to reconcile the separate images received from each eye, resulting in the perception of double vision.
- Dry eyes:
SMILE surgery may cause a temporary disruption in tear production, resulting in dry eyes. This dryness can lead to an uneven tear film on the surface of your eye, which may contribute to double vision due to light scattering on the rough and irregular corneal surface. - Other pre-existing conditions:
Although rare, individuals with pre-existing eye conditions such as strabismus (crossed eyes) or amblyopia (lazy eye) may experience exacerbated double vision after undergoing SMILE surgery.
Symptoms of Double Vision
- Experiencing double images of objects:
Noticing ghosting or shadowing around objects (Ghosting refers to perceiving a secondary, faint image alongside the primary one) - Experiencing blurred vision:
Feeling pain when moving your eyes - Struggling to focus:
Feeling discomfort or strain in your eyes - Experiencing nausea:
Suffering from headaches
Managing Double Vision After SMILE Surgery
Double vision after SMILE surgery is usually a temporary issue that resolves on its own as the eye heals, typically within a few days to a few weeks. However, it is important to manage your eyes properly to promote healing and prevent complications. Here are some Below are a few pointers to steer you in the right direction:
- Follow your doctor’s instructions diligently:
Use the prescribed eye drops regularly to combat dryness. It is crucial to attend all follow-up appointments to track and assess your progress diligently. - Protect your eyes:
Avoid rubbing them and wear sunglasses to shield them from bright light and wind. - Rest your eyes:
Give them ample rest by limiting excessive screen time and avoiding strenuous activities. - Maintain good posture:
Avoid slouching and ensure proper head and neck position to reduce eye strain.
Post-Surgery Evaluations and Communication
Patients undergoing SMILE surgery can find reassurance in the knowledge that a series of post-surgery evaluations is a standard part of the process. These follow-up visits provide a crucial opportunity to address any concerns, including double vision, with the eye care professionals overseeing the recovery.
Maintaining open and effective communication is essential, as it allows the medical team to assess the severity of the issue and recommend appropriate interventions, if necessary.
When to Seek Medical Attention?
If you encounter temporary double vision, it’s normal. However, it’s important to seek medical advice promptly if you experience any of the following:
- Persistent double vision lasting more than a few weeks
- Double vision getting worse or changing in pattern
- Eye pain, redness, or discharge
- Decreased vision
Remember, your health is paramount, and it’s best to consult a doctor if you have any concerns.
Treatment Options for Persistent Double Vision
In rare instances where double vision persists or worsens, follow-up procedures may be necessary for correction. The specific course of action will vary on a case-by-case basis. Patients need to understand that the majority of cases can be treated.
Treatment options include:
- Prescription glasses or contact lenses:
These can correct refractive errors that contribute to double vision. - Prism eyeglasses:
Specially designed lenses that redirect light rays, aiding the brain in merging the two images. - Eye muscle surgery:
In exceptional cases, surgery may be required to realign the eye muscles and resolve persistent double vision.
The Takeaway
Although extremely rare, experiencing double vision after SMILE surgery is a phenomenon that requires understanding and awareness. By gaining insight into the causes, symptoms, and management strategies, patients can navigate this phase and seek assistance if necessary.
It’s important to note that SMILE surgery remains a highly successful vision correction procedure, and instances of double vision are typically manageable through timely and appropriate interventions. By staying informed and actively engaging with healthcare providers, patients can ultimately enjoy the clear vision that SMILE surgery promises.
