Can Lasik Fix BVD?

Even after having their refraction improved, a small percentage of patients (less than 1%) report having poor vision. Having a backup plan in case your computer crashes is a good idea. According to an inquiry into whether complaints and visual function can be improved in post-Lasik patients with binocular dysfunction using internet-based computer software that offers practice in binocular convergence, divergence, and fusion ranges. Ten patients with 20/20 vision or better underwent postoperative testing for convergence range, compensatory ease, and other visual function markers. All of them experienced convergence insufficiency or accommodative spasm. Only some patients finished a rigorous online training programme for visual abilities that involved 20 or more periods of psycho-physical activity. Twenty minutes per session, 3-5 days per week. Other individuals (or 67%) significantly improved binocular function.

Others also made progress but needed the most in vision therapy to meet their treatment objectives. The findings demonstrate that postoperative binocular vision could be restored in individuals with binocular dysfunction. In the interest of patients to realise that they could need some vision treatment after surgery, they also make the case that identifying binocular abnormalities before surgery may be crucial. It is unknown whether improving binocular function before surgery might stop postoperative problems.


What is BVD?

A vertical imbalance hampers the synchronisation between your eyes in your eyes, such as one eye being marginally greater than the other, which is the root cause of BVD. Little muscles in the eyes work extra hard to realign themselves so you can yet view the surroundings. These muscles eventually grow tired and stretched from all the tension, which results in BVD and its accompanying symptoms, including migraines and vertigo.

In other words, since the eyes are not level, people with BVD see minor differences in the images they perceive in each eye. Your body has a built-in mechanism to “fix” this issue so you continue to see properly. Still, it has negative consequences like overused eye muscles, headaches, dizziness, balance issues, etc.


BVD physical signs and symptoms

  • Body Pain
  • Tendency to walk with one’s weight leaning to the left or right
  • Walks along the aisle and bumps into the shelves
  • Tilts head to improve vision
  • Falling over a lot
  • Recurring dizziness
  • Feeling weak
  • Feeling dizzy
  • Nausea
  • Discomfort in the cheekbones or nasal region
  • Disorientation

Signs of binocular vision:

  • Double vision, or diplopia,
  • Inadequate distance judgement or stereovision
  • Synchronisation issues between the body, hands, and eyes
  • Blinks, head tilts, or closes one eye to improve vision


Alternatives for therapy for BVD

You typically wear eyeglasses or contacts to correct refractive defects like presbyopia or poor eyesight, brought on by anomalies in your eyes’ structure. Binocular vision dysfunction is a different kind of eye condition brought on by an eye alignment issue and may be quite crippling. Depending on the patient, prismatic lenses capable of functioning as contact lenses or spectacles are aligned as our main therapy.


How do lens aligners work?

Correcting prismatic lenses operate to rectify the mismatch in your eyes, in contrast to conventional spectacles or contacts that address issues with a light-bending procedure that causes optical aberrations. To make it look as though the images you view belong to a single plane, they achieve this by modifying light rays before it reaches your eyes. The intraocular muscles no longer need to work as hard to realign your eyes because this deceives the brain into believing they are.

By wearing their prescribed alignment lenses, individuals with BVD and related diseases like vertical heterophobia (VH) typically notice that their problems gradually improve or go away entirely.


Identification and Therapy

Aligning prismatic lenses, which can be prescribed as spectacles or, in certain instances, as contact lenses—though we had discovered that aligning eyeglasses typically works better—is the standard therapy for this problem.

However, many people battled for years to receive a reliable diagnosis and a treatment outcome for their complaints. This is because most clinicians lack the knowledge or tools necessary to identify BVD.

You should get your eyes evaluated for BVD if you frequently experience symptoms like headaches, migraines, vertigo, difficulties concentrating, trouble reading, balance concerns, or anxiety. New alignment lenses can significantly enhance how you live by significantly reducing or eliminating your discomfort.


What can be fixed by LASIK?

Refractive defects are corrected through LASIK. Refractive defects affect how the eye focuses light; although a healthy eye will accurately bend light entering it, a retroactively flawed eye has trouble, leading to blurry vision. Vision problems do not constitute an eye illness because the physical characteristics of your eye cause them.

  • Myopia

Myopia, often called near-sightedness, is the condition that allows one to see up close but not far away. The prevalence of near-sightedness is very high and has been rising over the past few decades. Near-sightedness is treated with spectacles or lenses with a negative (-) prescription.

  • Hyperopia

Farsightedness, often referred to as hyperopia, is the inability to see up close yet the ability to see far away. Hyperopia affects approximately 25% of people. Farsightedness can be effectively treated with both LASIK and PRK.

  • Astigmatism

Usually, astigmatism causes vision problems in all ranges. The idea that LASIK cannot repair this kind of refraction problem is one of the most common myths regarding the procedure. Many people can have astigmatism treated by LASIK or PRK, which has been the case for more than ten years.

  • Presbyopia

Presbyopia is the typical age-related decrease of near-focusing capability. Presbyopia usually starts to affect persons after the age of 40. Everyone, especially those with excellent vision, may find this quite frustrating. The awesome thing is that both LASIK and PRK procedures can cure presbyopia by establishing monovision. It is an extremely efficient way to give patients excellent, functional vision without prescription glasses.

  • BVD

Treatment options for binocular vision impairment are numerous. Prism spectacles, vision treatment, and surgery are some of them. After LASIK, binocular function declines more than monocular function. This degradation worsens as the interocular disparities in abnormalities and cornea shape rise. These interocular variations ought to be minimised by advancements in ablation methods. Prism lenses, a specific type of optical lens, and vision therapy are effective treatments for BVD.
