Say Goodbye to Visual Difficulties After Cataract/ Refractive Eye Surgery, Train Your Brain to View Better, Faster


Did you undergo eye surgery to treat your cataracts with multifocal intraocular lenses? Or did you choose to reduce dependency on eyeglasses by undergoing refractive error surgery?


Are you finally ready to get back to your old hobbies of reading, gardening, or driving? Are vision disturbances post-surgery, like double vision, blurred vision, or poor depth perception, keeping you from enjoying these hobbies?


Worry not, though, as these visual disturbances are transient and treatable. Moreover, with the latest neuro-ophthalmology treatment advancements in post-surgical eye rehabilitation, the improvements in vision are quite rapid and remarkable.


Let us understand how and why these visual disturbances occur and what can you do about it:

What Happens During Cataract Eye Surgery?

Cataract surgery is performed when the eye lens becomes cloudy and severely hampers one’s vision. First, the damaged lens is removed, and a synthetic lens, known as an intraocular lens (IOL), is inserted in the place of the natural lens. This helps establish a clearer vision. In addition, one can opt for a multifocal IOL to get rid of distance and near glasses.

What Happens During Refractive Eye Surgery?

When the eye is unable to focus an image on the retina, it is called refractive error.


Refractive eye surgery is an elective procedure used to achieve freedom from eyeglasses or contact lenses and correct refractive error. There are various techniques to correct the eyes’ refractive error, such as using a laser to reshape the cornea (LASIK) or implanting an intraocular lens such as a phakic IOL. Phakic IOL surgery is usually performed when the patient desires refractive error correction but has a high refractive error or is unsuitable for routine LASIK procedures.

How Does Vision Recover After Vision-corrective Eye Surgery?

Perfect vision is dependent on both – the eyes and the brain, also known as neuro-ophthalmology. Light impulses and imagery coming from the surroundings are focused by the individual eye lenses, and visual inputs are then relayed to the brain. The brain interprets these two separate visual impulses and registers a single meaningful vision, letting one ‘see’ normally and clearly.


With cataract surgery, the old, damaged lens is replaced by a new synthetic IOL. For refractive surgery, either the cornea is reshaped, or a new phakic IOL is implanted in addition to the natural eye lens. The implanted IOL takes up the job of focusing visual imagery, and the brain now has to learn to interpret the new imagery relayed from the IOL.


New Lens, Same Brain


Over the years, the brain has been comfortably synchronized to interpret the visual imagery coming from the natural eye lens. However, when a Multifocal IOL is implanted, various visual images of a single source are created from the different focusing areas of the IOL. Now, the brain has to learn to interpret this unfamiliar imagery correctly. This learning curve is known as ‘Neuroadaptation.’

Why Do Binocular Visual Disturbances Occur After Vision-corrective Eye Surgery?

Cataract or refractive eye surgery may be completely successful, and one may have regained 20/20 visual acuity post-surgery. Yet, there are chances that one may not be completely satisfied with the surgery outcome. Post-surgery, patients are known to complain of binocular vision issues such as:

  • Blurred vision
  • Double vision
  • Poor depth perception

These are neuro-ophthalmology disorders or visual disturbances that can occur in the initial weeks post-surgery. It is thought that such disturbances occur due to the brain trying to adjust to interpret the images from the newly implanted intraocular lens and a newly reshaped cornea (in the case of LASIK surgery).


Over time, as the ‘neuroadaptation’ process occurs, the brain learns to adjust to the IOL, and the vision problems may improve. However, it may take anywhere between 6 months to a year for the visual disturbances to resolve completely. For approximately 10% of the patients, the disturbances are persistent.

How Can Vision Quality Be Improved With Neuro-Ophthalmology Treatments?

If binocular visual disturbances are persistent after eye surgery, it is likely due to a slower neuroadaptation. In such cases, one must seek advice from their eye doctor – who will perform a thorough eye check-up to rule out other possible causes of visual disturbance – and may advise to engage in certain technology-based activities that can help the brain adapt faster to the newly implanted IOL and/or the reshaped cornea.

Can The Brain Be Trained to View Better?

The brain possesses a unique property called ‘Neuroplasticity,’ which allows the brain and nerves to continuously remodel and adapt to changes. Because of its ability to adapt to changes in stimuli, it is possible to train the brain and the nerve network to learn and interpret the newer imagery coming from the IOL. This training can help reduce binocular visual disturbances after vision-corrective eye surgery.


Until recently, most eye surgeons advised the patient to wait it out and counseled them that the visual disturbances would fade with time. Now, newer and advanced techniques are available to help the brain navigate the learning curve quickly to achieve a clearer vision rapidly.


NeoAdaptor from Bynocs is an eye-rehabilitation program specifically designed for patients having visual disturbances – such as blurring, double vision, poor depth perception after vision-corrective eye surgery.


This program involves playing interactive games on a patented software interface utilizing specialized eyewear.


These neuro-ophthalmology treatment games offer simultaneous and separate stimulation to both eyes and thereby help improve the contrast sensitivity of images. In addition, the training enhances the brain’s response to visual stimuli and helps it correctly interpret the visual stimuli coming from the newly fitted IOL. This hastens the process of neuroadaptation, thereby reducing visual disturbances like blurring, double images and rapidly improving depth perception.

Advanced yet Easy

Undergoing a Bynocs-NeoAdaptor eye-rehabilitation program is easy and requires minimal equipment.


The necessary sessions may be undertaken in the eye-specialty clinic or at home once a person is prescribed the Bynocs-NeoAdaptor eye-rehabilitation program after vision-corrective eye surgery.


One needs an internet connection with a computer and special anaglyph glasses given by Bynocs. To perform the technique correctly, optometrist guidance is available through a video call.


Now that you know it is possible to improve vision after the vision-corrective eye surgery rapidly, say goodbye to blurred and double vision.

Train your brain to view better, faster.
