This blog is your guide to understanding its causes, symptoms, treatments, and post-operative management OF Posterior polar cataract. From uncovering the origins of this condition to exploring the various ways it manifests, we’ll cover the essentials to make complex concepts easy to grasp. Whether you’re seeking information for yourself or someone you care about, let’s navigate through the details of posterior polar cataracts together.

What Is Posterior Polar Cataract

Posterior polar cataract is a type of cataract that forms at the back of the eye’s lens, causing cloudiness and affecting vision. It is often linked to genetic factors. Common symptoms include blurry vision and sensitivity to bright light. Understanding the causes, symptoms, and treatment options is essential for managing it effectively.

Symptoms & Causes of Posterior Polar Cataract

Symptoms of Posterior Polar Cataract:

  • Blurred Vision: Difficulty in seeing clearly, especially when focusing on objects at different distances.
  • Sensitivity to Bright Light: Increased sensitivity to light, leading to glare or halos around lights.

Causes of Posterior Polar Cataract:

  • Genetic Factors: Often associated with a genetic predisposition, indicating a genetic link.
  • Unclear Triggers: Genetic influences play a significant role in the development of posterior polar cataracts.

Characteristics & Classification of Posterior Polar Cataract

Characteristics of Posterior Polar Cataract

  • Location: Post polar cataracts distinguish themselves by forming at the back of the lens, specifically in the region known as the posterior pole. This unique location contributes to distinct visual symptoms.
  • Opacity and Vision Impairment: The cloudiness of the lens interferes with the passage of light through the eye, resulting in impaired vision.
  • Symptoms: Beyond blurred vision, individuals commonly report increased sensitivity to bright light which can lead to discomfort against glare or halos around light sources, making activities like driving at night challenging.

Classification of Posterior Polar Cataract:

  • Congenital Variety: Some cases of posterior polar cataracts are congenital, meaning they are present at birth.
  • Acquired Form: In contrast, polar cataracts can also develop later in life, typically due to factors such as aging, trauma, or underlying medical conditions. The acquired variety may have different progression patterns and visual implications.
  • Genetic Association: Genetic tendency exists in certain instances, reinforcing the idea that genetic factors contribute to the development of posterior polar cataracts. Understanding this genetic link is crucial for both diagnosis and preventive measures.

Inheritance and Genetics

Familial Predisposition: Posterior polar cataracts often exhibit a familial tendency, suggesting a genetic influence in their development.

Genetic Mutations: Genetic mutations can be passed down through generations, increasing the likelihood of the condition within families.

Congenital Cases: In instances where post polar cataracts are present at birth (congenital), a strong association with genetic factors becomes apparent. Family history assessments often reveal patterns of inheritance.

Autosomal Dominant Inheritance: In some cases, posterior polar cataracts follow an autosomal dominant pattern, meaning that an affected individual has a 50% chance of passing the gene to their offspring.

Gene Mapping Studies: Ongoing research involves gene mapping studies to identify specific genes associated with polar cataracts.

Difference Between Posterior Polar Cataract and Posterior Subcapsular Cataract

AspectPosterior Polar CataractPosterior Subcapsular Cataract
Location in the EyeForms at the back of the lens (posterior pole).Develops just beneath the lens capsule.
Opacity AppearanceResults in cloudiness or opaqueness in the lens.Appears as a clouding near the back capsule.
Common SymptomsBlurred vision, sensitivity to light, glare.Glare, halos around lights, difficulty reading.
OnsetCan be congenital or acquired later in life.Typically develops later in life, often due to aging or factors like diabetes.
CausesOften associated with genetic factors.Linked to aging, diabetes, and corticosteroid use.
Treatment ApproachSurgical removal of the cloudy lens. Surgical complexity is higher in view of chances of pre-existing capsular weakness.Surgical intervention, with additional emphasis on managing underlying conditions.
PrognosisGenerally good with appropriate treatment.Generally good, but may pose challenges, especially in cases related to underlying health conditions.
Risk FactorsGenetic predisposition.Aging, diabetes, corticosteroid use.

Understanding the differences between posterior polar cataracts and posterior subcapsular cataracts is crucial for accurate diagnosis and tailored treatment plans.

Surgical Treatment for Posterior Polar Cataract

Below is the treatment procedure for posterior polar cataract in a step by step manner


  • Local anesthesia is administered for comfort.
  • Small incision made at the side of the cornea.


  • Circular opening created in the lens capsule.


  • Cloudy lens broken into small fragments using ultrasound.
  • Fragments suctioned out, leaving the capsule.

Artificial Lens Implantation:

  • Artificial intraocular lens (IOL) inserted to replace the natural lens.


  • Self-sealing incision; no stitches required.
  • Protective shield may be placed briefly.

Post-operative Care:

  • Prescribed eye drops for infection prevention and healing.


  • Improved vision shortly after surgery.
  • Follow post-operative care instructions for a few weeks.

Post Operative Management for Posterior Polar Cataract

Below are the major post operative care instructions:

  • Medication Adherence:

Follow prescribed eye drops & medications to prevent infection and boost healing.

  • Eye Protection:

Use recommended glasses to protect the eye from UV rays and dust.

  • Rest and Recovery:

Avoid strenuous activities, and refrain from heavy lifting initially.

  • Avoid Eye Rubbing:

Prevent rubbing or putting pressure on the operated eye.

  • Follow-up Appointments:

Attend all scheduled follow-up appointments with the eye surgeon.

  • Gradual Resumption of Activities:

Slowly resume daily activities based on the surgeon’s guidance.

  • Report Unusual Symptoms:

Immediately report signs of infection, increased pain, redness, or sudden vision changes.

  • Adhere to Restrictions:

Follow specific restrictions, such as avoiding swimming or dusty environments.

  • Hygiene Practices:

Maintain hand hygiene when applying eye drops or touching the eye area.

  • Patience and Adjustment:

Be patient with the recovery process and adjust activities as needed.

Posterior Polar Cataract in Children

Posterior polar cataract in children is a congenital condition where cloudiness forms at the back of the eye’s lens at an early age or at the time of birth. Key points include:

Genetic Link:

Strong association with genetic factors, often running in families.

Congenital Onset:

Typically present at birth or during infancy.

Effect on Vision:

Cloudiness can impact a child’s vision, causing blurred vision.


Pediatric ophthalmologists use specialized techniques, often under anesthesia, for accurate diagnosis.


Surgical intervention to remove the cloudy lens and implant an artificial lens for clear vision.

Post-operative Care:

Close monitoring post posterior polar cataract surgery for proper healing and vision development.


Timely intervention can lead to improved vision and a normal, healthy childhood.

Parents should be attentive to signs of visual issues in children, seeking professional evaluation for early intervention and optimal outcomes.

Cost Considerations for the treatment of Posterior Polar Cataract

The overall cost of addressing posterior polar cataracts varies, influenced by factors such as surgical intricacy, the surgeon’s expertise, geographical location, the chosen procedure, and additional medical considerations.

  • Medical Consultations: Initial eye exams and assessments.
  • Surgery Fees: Including the surgical procedure and surgeon’s fees.
  • Intraocular Lens (IOL): Cost varies based on the type of IOL lens selected.
  • Facility Fees: Charges associated with utilizing surgical facilities.
  • Postoperative Care: Includes follow-up appointments and prescribed medications.
  • Geographical Variation: Costs may differ by region and country.

Discuss estimated costs transparently with your healthcare provider. Verify coverage details with your insurance provider to have a complete understanding of potential expenses associated with posterior polar cataract treatment.
