Halos After Cataract Surgery: Understanding and Managing Visual Changes

October 8, 2020

Cataract surgery, a procedure that replaces the eye’s cloudy lens with an artificial intraocular lens, often leads to significant visual improvements. However, some patients experience halos around lights post-surgery. Understanding and addressing these changes is crucial for optimal visual recovery.

Halos: A Common Phenomenon

Halos, the rings of light that surround bright sources, are a typical response to intense lighting. While they can occur naturally, their presence is often more noticeable after cataract surgery. Factors like eyeglasses or contact lenses can also influence halo perception.

The Role of IOLs in Halos Post-Surgery

Following cataract surgery, the newly implanted IOL behind the iris and pupil plays a pivotal role in focusing light on the retina. This process, while improving overall vision, can sometimes result in the appearance of halos. The variety of IOLs available allows for customization based on individual visual needs, but adapting to these lenses can take time.

Dry Eye: A Contributing Factor

Dry eye, a condition characterized by insufficient lubrication on the eye’s surface, is another factor that can exacerbate halos post-surgery. With dry eye affecting over 7 million Americans and its prevalence increasing with age, it’s a significant concern for post-cataract surgery patients. Effective management of dry eye is essential to minimize halos and ensure a smoother cataract surgery recovery.

RevitalVision: Enhancing Vision Naturally

The RevitalVision post cataract program offers a unique and convenient approach to enhancing vision following cataract surgery. This therapy involves a series of computer exercises that patients can easily perform in the comfort of their own homes. Each session is conducted in front of a computer screen and typically spans about 30 minutes, making it a practical addition to daily routines.

A key feature of the therapy is its non-invasive nature. The program is entirely natural, relying on the brain’s own plasticity capabilities which leads to enhanced vision. It does not involve any pharmaceuticals, thereby eliminating concerns about drug-related side effects. Additionally, the therapy is free from known risks, complications, or adverse effects, making it a safe option for a wide range of patients.


The effectiveness of the program lies in its ability to stimulate neuroplasticity, the brain’s remarkable capacity to reorganize and adapt. By engaging in these exercises, patients encourage their visual system to adjust and improve their visual processing capabilities post-surgery. This process not only enhances clarity and sharpness of vision but also significantly improves the ability to enhance contrast sensitivity, which is often diminished after cataract surgery.

Achieving Optimal Post-Surgery Vision

Adapting to visual complications like halos after cataract surgery requires understanding and patience.  The quality of vision depends not only on the optics but also on the brain’s ability to process visual information. With RevitalVision, patients can effectively manage their post-surgical vision, by addressing the brain part of vision.
