Hypermature Cataracts: Causes, Symptoms, and Treatment Options
Total blindness or partial loss of vision due to cataracts is gradual and, when not treated, may result in serious complications. There is one sophisticated state of this condition, and it is called a hypermature cataract, which occurs when the cataract has been in a long duration and has advanced beyond the mature state.
At this stage, the lens of the eye becomes increasingly opaque and unstable, sometimes leaking lens material and triggering inflammation or secondary conditions. Early detection, regular monitoring, and timely cataract surgery can help prevent the escalation to this severe stage.
What is Hypermature Cataract?
A hypermature cataract refers to a cataract that has progressed to an advanced stage, where the lens proteins have degenerated extensively. This leads to a hardened or liquefied lens capsule, increased lens mobility, and sometimes leakage of lens contents into the eye.
The difference between mature and hypermature cataracts lies in the level of degeneration and the associated risks, including inflammation, raised intraocular pressure, and secondary glaucoma.
Types of Hypermature Cataracts
Hard or Intumescent Hypermature Cataract
This type involves a hardened, shrunken lens with a thickened capsule. It may be associated with fibrosis, making it more difficult to remove during surgery.
Morgagnian Cataract
In a Morgagnian cataract, the outer cortex of the lens liquefies while the dense nucleus sinks to the bottom. This form is especially prone to complications such as phacomorphic glaucoma or lens-induced inflammation.
Causes of Hypermature Cataract
Age-Related Risk
Ageing remains the most common cause. As we grow older, the proteins in the eye’s lens break down, leading to clouding and eventually a hypermature cataract if left untreated.
Genetic Factors
A family history of cataracts may increase the likelihood of developing this condition at an earlier age. While not all cases are hereditary, genetics can influence lens health.
UV Radiation Exposure
Prolonged exposure to ultraviolet light from the sun can accelerate cataract formation. Without adequate eye protection, individuals may be at risk of progressing to advanced stages.
Medical Conditions
Diabetes, hypertension, and chronic eye inflammation are among the systemic conditions that can lead to early or rapidly progressing cataracts. Poorly managed conditions may speed up the degeneration process.
Symptoms of Hypermature Cataracts
Vision Impairment and Blurred Vision
Patients often report difficulty seeing clearly, particularly in dim lighting. The clouded lens scatters light, making details harder to distinguish.
Difficulty in Reading, Driving
Tasks requiring sharp vision become challenging. Night driving, reading small text, or recognising faces may be significantly impaired.
Inflammation in the Eye
Leakage of lens material can cause an immune response, leading to redness, swelling, and pain. This is a potential complication in hypermature cataracts.
Increased Eye Pressure
The swollen lens may obstruct normal fluid drainage in the eye, causing increased intraocular pressure, a precursor to glaucoma.
Diagnosis of Hypermature Cataracts
Patient History and Symptoms
A detailed medical history helps identify risk factors, such as past eye trauma, diabetes, or a family history of hypermature cataracts.
Visual Acuity Test
This standard test measures clarity of vision. A significant reduction in vision can suggest the presence of an advanced cataract.
Slit-Lamp Examination
This detailed microscope exam allows ophthalmologists to inspect the lens and evaluate its density, mobility, and the presence of liquefied cortex or opacities.
B-scan
A B-scan ultrasound is performed when the lens opacity prevents a clear view of the retina. It helps detect retinal detachment, tumours, or other posterior segment conditions before cataract surgery.
Tonometry
A Tonometry test measures intraocular pressure and is crucial when there is suspicion of glaucoma or other pressure-related complications.
Treatment Options for Hypermature Cataracts
Surgical Removal: The Standard Treatment
Cataract surgery is the definitive treatment. Once the cataract reaches a hypermature stage, removal becomes necessary to prevent secondary issues such as glaucoma or lens-induced uveitis.
Non-Surgical Treatments (in early stages)
In rare cases, if caught early before the cataract becomes hypermature, visual aids like glasses or brighter lighting may help temporarily. However, surgery is eventually required.
Post-Surgery Care and Recovery After Hypermature Cataract Surgery
Immediate Aftercare (Eye Drops, Rest, and Monitoring)
After surgery, patients are typically prescribed anti-inflammatory and antibiotic eye drops. Strenuous activities and rubbing the eyes should be avoided.
Long-Term Eye Health Management
Regular follow-up visits are vital to monitor healing and manage any post-surgical complications. Patients should also undergo annual eye check-ups to assess overall ocular health and manage conditions like diabetes or hypertension that can affect eye health.
Effective Tips to Prevent Hypermature Cataracts
UV Protection
Wearing sunglasses that block 100% of UV rays can help slow cataract progression. This simple measure is particularly important in tropical regions with high sun exposure.
Nutrient-Rich Diet
A diet rich in antioxidants (such as vitamins A, C, and E), lutein, and zeaxanthin may protect the lens from oxidative stress.
Regular Eye Check-ups
Routine eye examinations allow for early detection of cataracts, ensuring treatment can be initiated before it reaches the hypermature stage.
Quit Smoking
Tobacco smoke contains free radicals that can damage lens proteins. Smoking cessation significantly lowers cataract risk.
Managing Diabetes
Well-controlled blood sugar levels can reduce the risk of developing cataracts and other complications like diabetic retinopathy.
When to Seek Medical Attention for Hypermature Cataracts
If you experience sudden vision loss, eye pain, or inflammation, seek immediate ophthalmic consultation. Early evaluation by a specialist can determine whether a hypermature cataract is present and if surgical intervention is necessary.

Frequently Asked Questions (FAQs) about Hypermature Cataracts
What is the difference between a mature and hypermature cataract?
A mature cataract completely clouds the lens, but the lens structure remains intact. A hypermature cataract goes further, with the lens becoming liquefied or hardened, and may leak proteins, increasing the risk of inflammation, elevated intraocular pressure, and secondary complications like phacomorphic glaucoma or lens-induced uveitis.
Can hypermature cataracts cause permanent vision loss?
Yes, if left untreated, hypermature cataracts can cause permanent vision loss. Leaked lens proteins may trigger inflammation, increased intraocular pressure, and optic nerve damage. Timely cataract surgery is essential to prevent irreversible complications, especially in cases where the cataract has advanced to a hypermature stage.
What colour are hypermature cataracts?
Hypermature cataracts may appear white, grey, or pearly due to liquefaction of the cortex. In Morgagnian cataracts, the hardened lens nucleus may sink within a milky-white liquefied capsule, giving a distinct layered appearance. The colour and density vary depending on the extent of degeneration.
What are the risks of hypermature cataracts after cataract surgery?
Surgical risks with hypermature cataracts include increased chances of capsular rupture, zonular instability, prolonged inflammation, and postoperative pressure spikes. Delayed surgery can also complicate intraocular lens implantation. However, these risks are manageable when treated by experienced surgeons with proper pre-operative planning and postoperative care.
What age group is more prone to hypermature cataracts?
Hypermature cataracts are more common in adults over 60, especially those who have delayed treatment of a diagnosed cataract. Older adults with limited access to eye care, underlying medical conditions, or poor health management are particularly at risk of developing this advanced cataract type.
Can hypermature cataracts be hereditary?
While hypermature cataracts are primarily age-related, hereditary factors can play a role. Individuals with a family history of early-onset cataracts may be genetically predisposed, increasing their likelihood of developing cataracts earlier and potentially progressing to the hypermature stage if untreated.
What are all the 4 stages of cataract?
The four stages of cataract development include:
- Initial/Immature Cataract: Slight clouding with minimal symptoms.
- Mature Cataract: Full lens opacity with significant vision reduction.
- Hypermature Cataract: Degeneration and possible liquefaction of lens material.
- Morgagnian Cataract: Nucleus sinks in a liquefied cortex, indicating advanced hypermaturity.
