What is Hypermature Cataract?

A hypermature cataract, also referred to as a Morgagnian cataract, represents an advanced stage of cataract progression where the eye’s lens becomes excessively hardened and clouded. This condition arises after an initial immature phase and a subsequent mature stage of cataract development. The defining feature of a hypermature cataract is a significant thickening and opacification of the lens, which leads to severe visual impairment.

The lens proteins in a hypermature cataract undergo extensive denaturation and aggregation, which results in the lens appearing whitish or yellowish and becoming densely opaque. Consequently, this impedes the passage of light, severely affecting the clarity of vision and mimicking the effect of looking through a fogged window. 

This advanced cataract stage is especially prone to causing complications like phacolytic glaucoma, where escaped lens proteins increase eye pressure, necessitating prompt medical intervention. 

The condition is more prevalent among populations with limited access to eye care services and among individuals who delay necessary cataract surgery. The primary treatment involves the surgical removal of the cloudy lens, which is then replaced with an artificial intraocular lens to restore clear vision.

What Causes hypermature Cataracts?

hypermature cataracts develop due to a variety of factors that contribute to the degeneration of the eye’s lens over time. The causes & complications have their mechanisms and risk factors:

causes of cataract

causes of cataract

  • Ageing: As the primary contributor, ageing causes the proteins within the lens to break down and aggregate, leading to increased opacity.
  • Ultraviolet Radiation: Exposure to UV light speeds up the degradation of lens proteins, hastening cataract formation.
  • Diabetes: High blood sugar levels promote glycation of lens proteins, which clouds the lens. Diabetics are therefore at a higher risk of developing cataracts earlier.
  • Medications: Long-term use of certain medications, particularly corticosteroids, can induce cataract development.
  • Smoking: The chemicals in tobacco smoke cause oxidative stress on the lens, exacerbating protein breakdown.
  • Nutritional Deficiency: Lack of vitamins and antioxidants, such as vitamin C and vitamin E, can lead to oxidative damage to the lens.
  • Trauma: Physical injury to the eye can accelerate cataract formation by disrupting the lens fibres.
  • Radiation Exposure: Exposure to ionising radiation, such as from X-rays or cancer treatments, can induce cataract formation.
  • Genetic Factors: Hereditary genetic mutations can predispose individuals to earlier and more rapid cataract development.

Types of hypermature Cataract

hypermature cataracts can present in various forms, each with its characteristics:

  • Intumescent hypermature Cataract: This type is marked by the swelling of the lens due to the absorption of water. The swelling increases intraocular pressure, which can lead to acute glaucoma.
  • Morgagnian Cataract: Named after Giovanni Battista Morgagni, this cataract sees the cortex of the lens completely liquefied, allowing the hardened nucleus to sink to the bottom.
  • Sclerotic hypermature Cataract: Here, the lens hardens entirely, becoming densely white and significantly impairing vision.

Hypermature Cataract with Capsular Bag Distension: This variant features an overstretched lens capsule, which is prone to tearing and can lead to the rapid onset of glaucoma.

Symptoms of hypermature Cataract

The symptoms of hypermature cataracts are typically severe and progress as follows:

  1. Severe Vision Loss: This drastic reduction in visual clarity is the most profound symptom.
  2. Blurred Vision: Vision becomes increasingly blurry, making daily activities difficult.
  3. Glare and Halos: Patients experience significant difficulties with bright lights and night driving.
  4. Colour Fading: Colours appear washed out and less vibrant, often with a yellowish tint.
  5. Frequent Prescription Changes: A rapid progression in lens opacity necessitates constant updates in vision correction.
  6. Difficulty in Low Light: Compromised vision in dim lighting conditions due to the reduced light passage through the lens.
  7. Vision Double: In some cases, the cataract can cause double vision or ghost images in the affected eye.

Diagnosis and Evaluation of hypermature Cataract

Diagnosing hypermature cataracts involves a series of evaluations that confirm the presence and assess the severity of the cataract. Each diagnostic tool plays a crucial role in planning the appropriate treatment:

  • Visual Acuity Test: This test measures how well the patient can see at various distances. A significant decrease in visual acuity often indicates the presence of cataracts.
  • Slit-Lamp Examination: A slit lamp provides a magnified, three-dimensional view of the different structures at the front of the eye, including the lens. This examination helps identify the type and extent of the cataract.
  • Dilated Eye Exam: Drops are used to widen the pupil, allowing a better view of the entire lens and the back of the eye. This comprehensive view helps to assess the cataract’s impact on the eye.
  • Tonometry: This test measures the pressure inside the eye. Elevated pressure can indicate complications associated with hypermature cataracts, such as phacolytic glaucoma.

Ultrasonography: In cases where the cataract completely obscures the view to the back of the eye, an ultrasound can be performed to check the health of the areas not visible through the cataract.

How the hypermature Cataract Can be Treated?

Treatment for hypermature cataracts primarily involves surgical intervention, as the lens’s opacity cannot be reversed with medication or corrective eyewear. The standard procedure is:

  • Cataract Surgery: The most effective treatment, this surgery involves the removal of the clouded lens, which is then replaced with a clear, artificial intraocular lens (IOL). The surgery is generally safe and highly successful in restoring vision.
  • Phacoemulsification: This modern cataract surgery technique uses ultrasound waves to break up the dense, cloudy lens into small pieces, which are then removed from the eye. It is particularly effective for hypermature cataracts because it requires a smaller incision, reducing recovery time and complications.

Postoperative Care: Following surgery, patients may need to use eye drops to prevent infection and control eye pressure. Regular follow-up appointments are crucial to monitor the healing process and ensure the success of the surgery.

When is hypermature Cataract Considered Serious?

While all cataracts can affect vision, hypermature cataracts are particularly serious due to their potential to cause severe vision loss and other complications.

  • Risk of Phacolytic Glaucoma: When lens proteins leak into the eye, causing increased intraocular pressure.
  • Lens Induced Uveitis: An inflammatory response caused by lens proteins that irritate the eye tissues.
  • Capsular Bag Distension: Excessive swelling can lead to tears in the lens capsule, posing risks of lens dislocation.

Decreased Surgical Success: The denser and more advanced the cataract, the more challenging the surgery and the higher the risk of postoperative complications.

Prevention of hypermature Cataract

While it’s difficult to completely prevent cataracts, particularly those due to aging, certain measures can reduce the risk and delay their progression:

  • Regular Eye Examinations: Frequent check-ups can detect cataracts and other eye problems early.
  • UV Protection: Wearing sunglasses that block UV rays helps protect the lens from UV-induced damage.
  • Smoking Cessation: Avoiding smoking reduces the risk of cataracts.
  • Diet and Nutrition: A diet rich in antioxidants (vitamins C and E) can help slow lens ageing.
  • Manage Health Conditions: Proper management of diabetes and other systemic health issues can minimise eye complications.

Consult an Eye Care Professional: Regular consultations with an ophthalmologist are crucial, especially for those experiencing vision changes, to manage the condition effectively and prevent serious complications.

Myths and Facts About hypermature Cataract

Here are a few myths and facts about hypermature cataract:

  • Myth: Cataracts can be dissolved with eye drops.
    • Fact: No eye drops have been scientifically proven to dissolve cataracts. Surgery is the only effective treatment for hypermature cataracts.
  • Myth: Cataracts must be ripe before surgery.
    • Fact: With modern surgical techniques, cataracts can be removed at any stage. Waiting for the cataract to become ‘ripe’ is unnecessary and can lead to avoidable vision impairment.
  • Myth: Cataract surgery is risky and requires lengthy recovery.
    • Fact: Cataract surgery is one of the safest and most common surgeries performed. Recovery typically is quick, with many patients experiencing improved vision within a day.
  • Myth: Cataracts can spread from one eye to the other.

Fact: Cataracts do not spread between eyes. They develop independently but can appear in both eyes at different rates.

When to Consult a Doctor for hypermature Cataract?

If you notice any signs of vision impairment such as blurry vision, difficulty seeing at night, or colours appearing faded, it’s important to consult an ophthalmologist. An ophthalmologist specialises in eye health, including the diagnosis and treatment of cataract conditions. 

Consulting a specialist is crucial as they can provide a comprehensive evaluation of eye health and determine the appropriate treatment. Early diagnosis and treatment can prevent complications such as phacolytic glaucoma and significantly improve the quality of life.

FAQs

What are the main causes of hypermature cataracts?

The main causes include ageing, UV radiation, diabetes, certain medications, smoking, nutritional deficiencies, physical trauma, radiation exposure, and genetic factors. Each of these factors contributes to the degradation of the lens proteins, accelerating the opacity and hardening process.

What are the types of hypermature cataracts?

Types include Intumescent, which involves lens swelling; Morgagnian, where the lens cortex liquefies; Sclerotic, where the lens hardens completely; and Capsular Bag Distension, leading to possible lens dislocation. Each type presents unique challenges and risks for vision and requires specific surgical approaches.

How is a hypermature cataract treated?

The primary treatment is surgical removal of the clouded lens, replaced with an artificial intraocular lens. Techniques like phacoemulsification are commonly used for effective results. Post-surgery, patients usually experience a significant improvement in vision, often within days.

Can diet affect the progression of hypermature cataracts?

Yes, a diet lacking in antioxidants like vitamins C and E can accelerate cataract progression, while a nutrient-rich diet might slow it down. Consuming foods high in these antioxidants can help maintain lens clarity for a longer period.

Is there a way to prevent hypermature cataracts?

While completely preventing cataracts may not be possible, protecting eyes from UV rays, managing health conditions, and avoiding smoking can reduce risk and delay progression. Regular eye exams also play a crucial role in early detection and management.

What complications can arise from untreated hypermature cataracts?

Untreated hypermature cataracts can lead to phacolytic glaucoma, lens-induced uveitis, and decreased surgical success due to advanced cataract density. These complications can result in permanent vision loss if not addressed promptly.

Why is it important to treat hypermature cataracts early?

Early treatment prevents complications like glaucoma and ensures better surgical outcomes and quicker recovery of vision. Early intervention also helps maintain a higher quality of life by restoring vision clarity sooner.

Can hypermature cataracts recur after surgery?
