Phaco with Foldable IOL is performed primarily to treat cataracts, a condition in which the natural lens becomes cloudy. Cataracts may develop due to multiple factors:

Causes

1. Age-related degeneration: The most common cause; natural proteins in the lens break down with age.

2. Diabetes mellitus: Increases the rate of cataract formation due to metabolic stress.

3. Trauma: Blunt or penetrating injuries accelerate lens opacification.

4. Prolonged steroid use: Systemic or topical steroids increase the risk of posterior subcapsular cataracts.

5. Congenital factors: Inherited disorders, metabolic diseases, or developmental abnormalities.

6. UV radiation exposure: Long-term exposure to sunlight accelerates oxidative damage to the lens.

7. Inflammatory eye conditions: Uveitis and chronic inflammation disrupt lens metabolism.

Risk Factors

1. Smoking, excessive alcohol use, obesity, malnutrition

2. Systemic diseases like hypertension and dyslipidemia

3. Pre-existing ocular diseases like glaucoma, keratopathy, or retinal disorders

4. Occupational exposure to heat, radiation, or bright light

5. Previous ocular surgery or trauma

These factors influence the timing, complexity, and expected outcomes of phacoemulsification.

Patients needing Phaco with Foldable IOL typically report a gradual decline in vision due to cataracts. Symptoms include:

Symptoms

1. Blurred or hazy vision interfering with daily activities

2. Difficulty reading, driving at night, or recognizing faces

3. Increased sensitivity to bright lights, glare, and halos

4. Dull or faded perception of colors

5. Frequent changes in glasses prescription

6. Double vision in one eye due to lens irregularities

7. Reduced contrast sensitivity, affecting mobility and independence

Clinical Signs

1. Lens opacity visible on slit-lamp examination

2. Decreased red reflex

3. Reduced visual acuity uncorrectable by glasses

4. Dense nuclear sclerosis or cortical changes

5. Coexisting signs of glaucoma or macular disease

1. What is phacoemulsification with foldable IOL, and how does it differ from traditional cataract surgery?

Phacoemulsification with foldable intraocular lens (IOL) is a minimally invasive, modern technique for cataract removal. Cataracts occur when the natural lens becomes cloudy due to aging, trauma, or systemic conditions like diabetes. In phacoemulsification:

1. A tiny 2-3 mm corneal incision is made, much smaller than the 10-12 mm incision used in traditional extracapsular cataract surgery.

2. A high-frequency ultrasonic probe emulsifies the cloudy lens, turning it into microscopic pieces that are suctioned out.

3. A foldable IOL is inserted through the same small incision and unfolds within the eye to restore clarity.

Compared to traditional methods, phacoemulsification reduces surgical trauma, minimizes post-operative astigmatism, accelerates recovery, and allows for premium IOL implantation, providing both functional and cosmetic benefits.
