Cataracts are one of the leading causes of vision impairment globally, affecting millions of people, particularly as they age. As the lens of the eye becomes cloudy, vision deteriorates, significantly impacting daily activities. This impairment is especially pronounced at night, where conditions such as glare, haloes, and reduced contrast can make it difficult to see. This blog explores the relationship between cataracts and night vision, how cataract surgery can restore clarity, and what patients can expect during recovery.

Understanding cataracts

Cataracts form when proteins in the eye’s natural lens clump together, leading to cloudiness. The progression of cataracts typically follows a predictable path:

• Early stage: Initially, vision may become slightly blurred or cloudy. Patients often notice difficulty with glare, particularly from headlights at night.
  
  
• Moderate stage: As cataracts progress, patients may struggle to see in low-light conditions, affecting activities like night driving, reading, or moving around in dimly lit environments.
  
  
• Advanced stage: In severe cases, vision can become significantly impaired, resembling looking through a frosted window.
  
  

Symptoms of cataracts

• Blurred or cloudy vision.
• Difficulty seeing at night or in low light.
• Increased sensitivity to glare and halos around lights.
• Frequent changes in prescription glasses or contact lenses.
• Faded colours and contrast sensitivity.
  
  

Benefits of cataract surgery

Cataract surgery is one of the most common and successful surgical procedures performed worldwide. Here is a breakdown of the benefits:

• Improved visual clarity: Most patients experience remarkable improvements in both day and night vision. Clearer vision enhances daily activities, from driving to reading and enjoying hobbies.
  
  

• Reduced glare and halo effects: Modern intraocular lenses (IOLs) have been designed to minimise glare and haloes, which are particularly troublesome at night. This advancement allows for more comfortable night-time driving and activities.
  
  

• Increased safety: Better night vision reduces the risk of accidents and enhances overall safety during nighttime activities. Improved depth perception and contrast sensitivity also play important roles.
  
  

• Enhanced quality of life: With restored vision, patients often report improved confidence and a greater willingness to engage in social activities, travel, and outdoor pursuits.
  
  

How does cataract surgery improve night vision?

Cataract surgery not only removes the cloudy lens but also restores the eye’s ability to function optimally in low-light conditions. Here is how it works:

• Restoration of light entry: The primary goal of cataract surgery is to replace the cloudy lens with a clear artificial IOL. This restoration allows more light to enter the eye, which is essential for good night vision. With more light available, the retina can better process images, resulting in clearer vision.
  
  

• Optimised lens technology: Patients have options when it comes to the type of IOL used during surgery:
  
  
• Monofocal lenses: These provide clear vision at a single distance (usually far) and can be combined with glasses for near vision tasks.
  
  
• Extended depth of focus and multifocal lenses: These allow patients to see clearly at various distances, reducing the need for glasses. It is important to note that some of these premium IOLs can cause increase glare and halo symptoms at night.
  
  
• Toric lenses: Designed to correct astigmatism, these lenses provide sharper vision in all lighting conditions, contributing to better performance at night.
  

• Contrast sensitivity improvement: Cataracts often impair contrast sensitivity, making it hard to distinguish objects from their backgrounds, especially in dim lighting. Post-surgery, many patients experience a significant enhancement in their ability to perceive contrasts, allowing for safer navigation in low-light environments.
  
  

• Reduction of nighttime discomfort: Many patients report reduced discomfort from glare and haloes around lights after surgery. This comfort is crucial for activities such as driving at night, where glare from oncoming traffic can be particularly problematic.
  
  

What to expect post-surgery?

Understanding the recovery process is vital for patients considering cataract surgery:

• Healing period: The recovery time varies among patients, but many experience significant improvements within days. However, full vision stabilisation may take a few weeks.
  
  

• Gradual improvement: Patients often notice that their vision continues to improve in the days and weeks following surgery. Initial adjustments to the new lens may occur, leading to enhanced clarity and comfort.
  
  

• Post-operative care: Following surgery, it is essential to adhere to the surgeon’s instructions, which may include:
  
  

1. 1. • Avoiding strenuous activities or heavy lifting.
      • Using prescribed eye drops to prevent infection and manage inflammation.
      • Attending follow-up appointments to monitor recovery progress and address any concerns.
        
        

• Potential side effects: While most patients have a smooth recovery, some may experience temporary side effects, such as dry eyes or mild discomfort. These typically resolve as healing progresses.
