Both LASIK and PRK are laser eye surgeries designed to correct vision problems like nearsightedness, farsightedness, and astigmatism. While they share the same goal, their procedures and recovery processes differ.

How LASIK Works

LASIK involves creating a thin flap on the cornea using a laser. The surgeon then reshapes the underlying corneal tissue to correct vision. The flap is repositioned, allowing for a quicker recovery.

Pros of LASIK:

• Faster recovery time, often with improved vision within 24 hours.
• Minimal discomfort during and after the procedure.
• Suitable for most patients with moderate to severe refractive errors.

Cons of LASIK:

• Not ideal for individuals with thin corneas or severe dry eye.
• Slightly higher risk of complications related to the corneal flap.

How PRK Works

PRK, or Photorefractive Keratectomy, removes the outer layer of the cornea before reshaping it with a laser. Unlike LASIK, no flap is created.

Pros of PRK:

• Suitable for patients with thin corneas or those at risk of flap complications.
• No risk of flap-related issues post-surgery.
• Often recommended for individuals with mild to moderate vision problems.

Cons of PRK:

• Longer recovery time, with vision stabilizing over several days to weeks.
• More discomfort during the initial healing phase.

Why Diabetic Patients Need Regular Eye Exams

High blood sugar levels can weaken or damage the small blood vessels in the retina, leading to diabetic retinopathy. In early stages, this condition may not cause any symptoms, which is why many people are unaware they have it.

A yearly eye exam helps detect:

• Early diabetic retinopathy
• Macular edema (swelling of the retina)
• Cataracts
• Glaucoma
• Blood vessel changes that require monitoring

Early detection allows treatment to begin before vision is affected.

What Happens During a Diabetic Eye Checkup

A comprehensive diabetic eye examination may include:

• Dilated eye exam to view the retina more clearly
• OCT scan to detect swelling or structural changes
• Retinal photographs to monitor progression over time
• Visual acuity and pressure tests

These painless tests help identify even the smallest signs of damage.

How Early Intervention Protects Sight

When diabetic eye disease is caught early, treatment is far more effective. Common treatments include:

• Anti-VEGF injections to reduce swelling
• Laser therapy to seal leaking blood vessels
• Vitrectomy for advanced stages with bleeding
• Improved diabetes control to slow progression

Many patients maintain good vision for years with proper monitoring and timely care.

Who Needs More Frequent Checkups?

Some people may need eye exams every 6 months instead of once a year, especially if they have:

• Long-standing diabetes
• High blood pressure
• Pregnancy
• Vision changes
• Early signs of diabetic retinopathy

Your eye specialist will recommend the best screening schedule based on your condition.

If you are unsure whether your symptoms require emergency attention, it is safer to call your healthcare provider or eye clinic for advice.

Types and Causes

Conjunctivitis may result from various causes:

• Viral Conjunctivitis: Often highly contagious; frequently linked to adenovirus.
• Bacterial Conjunctivitis: Produces thicker, sticky discharge; needs antibiotic therapy.
• Allergic Conjunctivitis: Triggered by pollen, dust, pets, or other allergens; usually affects both eyes.
• Irritant Conjunctivitis: Caused by chemicals, smoke, pollution, or foreign particles.

Correct diagnosis of the cause is essential to guide appropriate treatment.

Symptoms to Watch For

Typical signs of conjunctivitis include:

• Redness of one or both eyes
• Itching, burning, or gritty sensation
• Watery or sticky discharge (especially overnight)
• Swollen eyelids
• Sensitivity to light

If symptoms worsen rapidly, vision becomes seriously blurred, or you experience pain, seek medical attention promptly.

Prevalence in Pakistan

Conjunctivitis is a frequent eye condition in Pakistan, and recent years have seen major outbreaks, particularly of viral (adenoviral) conjunctivitis:

• In September 2023, Punjab recorded 86,133 cases of pink eye, marking one of the largest documented outbreaks in Pakistan’s recent history.
• Between January and September 2023, over 288,000 cases of adenoviral conjunctivitis were reported nationwide.
• Adenovirus is implicated in 65–90% of viral conjunctivitis cases, making it the dominant infecting agent during epidemics.
• In Karachi, studies have found that around 75% of pink eye cases were linked to adenovirus, while about 18% involved bacterial causes.
• Regarding allergic forms, 19.2% of schoolchildren in Karachi (ages 5–19) were found to suffer from allergic conjunctivitis in one survey.

These figures highlight how common and recurrent conjunctivitis is in Pakistan, especially during seasonal changes, in crowded urban areas, and in settings with limited hygiene and air quality control.

Diagnosis & Treatment in Karachi

A comprehensive eye exam by an ophthalmologist or optometrist can confirm conjunctivitis and its underlying cause. In Karachi, the following treatments are available:

• Viral: Supportive care such as lubricating drops, cold compresses, and hygiene.
• Bacterial: Antibiotic eye drops or ointments as prescribed.
• Allergic: Antihistamine or anti-allergy eye drops, along with identifying and removing triggers.
• Irritant: Flushing the eyes and avoiding the irritant source.

Also important are hygiene practices—frequent hand washing, not sharing towels or pillows, and avoiding eye rubbing—to limit spread.

If you are unsure whether your symptoms require emergency attention, it is safer to call your healthcare provider or eye clinic for advice.

Eye drops are commonly prescribed for conditions like dry eyes, glaucoma, infections, or post-surgery healing. Using them correctly is essential to ensure the medication works effectively and to avoid contamination or wasted drops.

Here is a step-by-step guide to applying eye drops safely.

1. Wash your hands thoroughly
   Always start with clean hands to prevent introducing bacteria into your eye.
2. Shake the bottle if instructed
   Some medications require shaking before use. Check the label or ask your doctor.
3. Tilt your head back and look up
   Sitting or lying down can make the process easier and steadier.
4. Gently pull down your lower eyelid
   This creates a small pocket between your eye and eyelid where the drop will sit.
5. Hold the dropper above your eye
   Keep it close but do not touch your eye, eyelashes, or skin to avoid contamination.
6. Squeeze one drop into the pocket
   Most medications are effective with just one drop. Using more does not increase benefit.
7. Close your eye gently
   Do not squeeze shut; instead, close your eyelid and look down for 1–2 minutes.
8. Press lightly on the inner corner
   Place a finger near the nose at the tear duct to prevent the drop from draining away, increasing absorption and reducing side effects.
9. Wipe away excess
   Use a clean tissue to gently dab any extra liquid from around the eye.
10. Wait before applying another medication
    If you use multiple eye drops, wait at least 5 minutes between different medications.

Extra Tips

• Always follow your doctor’s instructions for dosage and frequency.
• Store eye drops as directed (some may need refrigeration).
• Do not share your eye drops with others.
• Replace bottles before their expiration date.
