What are Hypermature Cataract ?
A hypermature cataract is a very advanced stage of a cataract. It develops when a normal cataract is left untreated for a long time. In this stage, the lens becomes completely opaque and may even shrink or leak lens material inside the eye.
In earlier stages, the lens only becomes cloudy. But in a hypermature cataract, the structure of the lens changes more seriously. The cortex may liquefy, and the nucleus becomes hard. Sometimes the lens capsule becomes wrinkled.
There are two types of hypermature cataract:
- Hard or Intumescent Hypermature Cataract – In this type, the lens may initially swell due to fluid accumulation (intumescent stage), causing increased thickness and sometimes a rise in eye pressure.
- Morgagnian Cataract – In this advanced form, the cortex becomes completely liquefied, and the hard nucleus sinks to the bottom of the lens capsule.
Causes of Hypermature Cataract
Hypermature cataracts usually develop when a cataract is left untreated for a long period, allowing it to progress to an advanced stage.
The primary cause is long-standing, untreated age-related cataract, which gradually becomes dense and overripe
Other contributing factors include:
- Advanced age, which increases the risk of cataract progression
- Delayed or lack of treatment, often due to limited access to eye care or fear of surgery
- Chronic eye conditions, such as uveitis or other inflammatory diseases
- History of eye trauma, which can accelerate cataract changes
- Systemic conditions (in some cases), such as diabetes, which may speed up progression
In some cases, hypermature cataract can lead to complications such as lens-induced glaucoma. Leakage of lens proteins may cause inflammation inside the eye.

Symptoms
Symptoms of Hypermature Cataracts
Vision is usually very poor in this stage. Common symptoms include:
- Severe blurring of vision
- Only light perception or hand movement vision
- White or milky appearance in the pupil
- Glare and difficulty in bright light
In some cases, patients may experience:
- Eye pain
- Redness
- Sudden increase in eye pressure
Treatments
Treatment Options for Hypermature Cataracts
- Clouded, blurred, or dim vision.
- Difficulty seeing at night.
- Increased sensitivity to light and glare.
- Need for brighter light for reading and other activities.
- Seeing “halos” around lights.
- Frequent changes in eyeglass or contact lens prescription.
- Fading or yellowing of colors.
- Double vision in one eye.
The only effective treatment is Hypermature Cataract surgery. No medicine or eye drop can reverse this stage.
Surgery may be slightly more complicated compared to early cataracts because the lens becomes very hard. Sometimes, manual small incision cataract surgery is preferred. In other cases, phacoemulsification can be done depending on the surgeon’s assessment.
An intraocular lens is implanted after removing the cloudy lens.
If there is associated inflammation or high eye pressure, it must be treated before or along with surgery. Post-operative care is very important in these patients.
How are Hypermature Cataract Diagnosed?
An ophthalmologist diagnoses a hypermature cataract during eye examination. Vision testing shows very low vision.
On slit lamp examination, the lens appears completely opaque. In some cases, the lens may look shrunken or wrinkled.
Eye pressure is checked because advanced cataracts can raise intraocular pressure. If the retina cannot be seen due to dense opacity, an ultrasound of the eye may be done to assess the back of the eye.
How to Prevent Hypermature Cataracts?
The best way to prevent hypermature cataract is timely treatment of regular cataract.
Simple steps include:
- Regular eye check-up after 50 years
- Not ignoring gradual vision loss
- Undergoing surgery when advised by the doctor
- Managing systemic diseases like diabetes
Early cataract surgery is safe and gives better results compared to waiting until it becomes hypermature.
Conclusion
Hypermature cataract is an advanced and neglected stage of cataract. Vision becomes severely affected, and complications may occur if the management of Hypermature Cataract is delayed.
The good part is that surgery can still restore vision in most cases. However, timely intervention is always better. Elderly patients should not postpone cataract surgery once it starts affecting daily life.
Frequently Asked Questions:
About Hypermature Cataract
What are the early symptoms of hypermature cataracts?
Early symptoms start as common cataracts, like blurred vision and glare. If untreated, vision gradually worsens.
At what age do hypermature cataracts usually develop?
They are usually seen in elderly people, mostly above 65 years, especially when a cataract is ignored for a long time.
What is the best treatment for hypermature cataracts?
Surgical removal of the cataract with intraocular lens implantation is the best and only effective treatment.
When is surgery required for hypermature cataracts?
Hypermature cataract surgery is required as soon as vision becomes severely reduced or if complications like pain and high eye pressure develop.
How long is the recovery after surgery for hypermature cataracts?
Initial recovery takes about 3 to 4 weeks. Some patients may need slightly longer follow-up due to associated inflammation.
What type of lens is best for hypermature cataracts?
Most patients do well with a standard monofocal intraocular lens. The final choice depends on eye condition and the surgeon’s advice.
Does diabetes increase the risk of hypermature cataracts?
Diabetes can speed up cataract formation.
