Risk Factors

While LASIK is generally safe and effective, it’s not suitable for everyone. Understanding the risk factors helps determine if you’re a good candidate.

🧬 1. Unstable Vision

• Frequent changes in your eyeglass or contact lens prescription (especially in the last 1–2 years)
• Can lead to poor long-term results after LASIK

🩺 2. Existing Eye Conditions

• Severe dry eyes
• Keratoconus (thinning of the cornea)
• Glaucoma or cataracts
• Eye infections or inflammation

📉 3. Thin or Irregular Corneas

• A thin cornea may not support the reshaping needed in LASIK
• Risk of complications like corneal ectasia

🧪 4. Autoimmune or Immunodeficiency Disorders

• Conditions like lupus, rheumatoid arthritis, or HIV may affect healing

👁️ 5. Large Pupils

• May lead to glare, halos, and night vision problems after LASIK

🤰 6. Pregnancy or Breastfeeding

• Hormonal changes can affect vision stability

🧓 7. Age Factors

• Under 18: Vision may still be changing
• Over 40: You may develop presbyopia (difficulty seeing close objects), for which LASIK may not help fully

🚭 8. Smoking & Poor Healing

• Smoking or poor general health may slow recovery or increase risks

Symptoms

• Blurry Vision (Refractive Errors):
• Difficulty seeing clearly at distance (myopia)
• Trouble reading or seeing up close (hyperopia)
• Distorted vision due to irregular cornea shape (astigmatism)
• Frequent Headaches or Eye Strain:
• Caused by constantly squinting to focus on objects
• Difficulty Seeing at Night:
• Poor night vision or halos around lights
• Constant Need to Update Glasses/Contacts:
• Changing prescription frequently due to unstable vision
• Dry or Irritated Eyes (sometimes):
• Can be related to overuse of contact lenses or eye fatigue
• Dependence on Glasses or Contact Lenses:
• If you’re tired of using them daily or during sports/activities

Preparation for LASIK Eye Surgery

Proper preparation is crucial to ensure the best results and a smooth recovery from LASIK surgery. Here’s a complete guide:

📅 1. Pre-Surgery Consultation

• Eye exam to measure corneal thickness, pupil size, and refractive error
• Corneal topography and wavefront analysis
• Discussion of suitability, expectations, and possible outcomes

👓 2. Stop Wearing Contact Lenses

• Soft lenses: Stop wearing 1 week before the exam
• Hard/gas permeable lenses: Stop 2–4 weeks before
• This allows your cornea to return to its natural shape

🍔 3. On the Day of Surgery

• Eat a light meal before surgery (unless advised otherwise)
• Avoid caffeine to reduce eye dryness and anxiety
• Do not wear makeup, lotion, perfume, or eye cream
  (These can interfere with the laser and increase infection risk)

🧴 4. Clean Your Face Thoroughly

• Wash your face to remove any debris, oils, or products
• Keep your eyelashes clean to reduce the risk of infection

🕶️ 5. Arrange Transportation

• You will not be allowed to drive after surgery
• Arrange for a friend or family member to accompany you

📋 6. Review Instructions with Your Doctor

• Understand post-operative care, medications, and activity restrictions
• Ask about eye drops, protective eye shields, and follow-up visits

Procedure

LASIK (Laser-Assisted In Situ Keratomileusis) is a quick and generally painless surgery to correct refractive vision errors like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.

🕒 Total Time: 15–30 minutes for both eyes

💡 Anesthesia: Numbing eye drops (no injections)

🔬 Step-by-Step LASIK Procedure

✅ 1. Numbing the Eye

• Special numbing drops are applied to prevent pain during the procedure.

✅ 2. Eye Lid Holder Placement

• A lid speculum is used to gently hold your eyelids open.

✅ 3. Corneal Flap Creation

• A thin flap is created in the outer cornea using:
  • Microkeratome blade (traditional method)
  • or Femtosecond laser (bladeless, more precise)
• The flap is lifted to expose the inner cornea.

✅ 4. Laser Reshaping of Cornea

• A cool excimer laser reshapes the corneal tissue to correct the vision error.
  • Removes microscopic amounts of tissue
  • Guided by a computer based on your eye measurements

✅ 5. Repositioning the Corneal Flap

• The flap is carefully placed back over the treated area.
• It naturally adheres without stitches and begins healing immediately.

✅ 6. Recovery & Monitoring

• You’ll rest for a short time at the clinic.
• Blurred vision and light sensitivity are normal for the first few hours.

Post-Procedure

Proper post-operative care is essential to ensure a smooth recovery and optimal vision correction after LASIK.

👁️ Immediately After Surgery

• Blurry vision, mild burning, tearing, or foreign body sensation is normal
• Light sensitivity and watery eyes may last a few hours
• Vision often improves within 24–48 hours

🧴 1. Eye Drops & Medications

• Use antibiotic and anti-inflammatory eye drops as prescribed
• Apply lubricating drops to prevent dryness
• Follow the exact schedule given by your doctor

🛏️ 2. Rest & Recovery

• Sleep for a few hours after surgery to help healing
• Wear the provided eye shield at night for 1 week
• Avoid rubbing your eyes at all costs

🚫 3. Activities to Avoid (for 1–2 Weeks)

• Swimming, hot tubs, or saunas
• Dusty or smoky environments
• Heavy exercise or contact sports
• Makeup around the eyes (1 week minimum)

😎 4. Protect Your Eyes

• Wear sunglasses when outdoors to protect from UV light
• Avoid direct air (fans, AC, hairdryers) into your eyes

🗓️ 5. Follow-Up Appointments

• First check-up: Within 24–48 hours after surgery
• Additional visits: As advised (1 week, 1 month, 3 months, etc.)

Success Rates

LASIK is one of the most successful and commonly performed eye surgeries worldwide — and India is no exception. Here’s a clear overview of its success rates and outcomes:

📊 LASIK Surgery Success Rates

• ✅ 95–98% of patients achieve 20/40 vision or better (good enough to drive without glasses)
• ✅ 85–90% achieve 20/20 vision or better
• ✅ Low complication rate: Less than 1% of patients experience serious side effects
• ✅ Most patients resume normal activities within 24–48 hours

👨‍⚕️ Factors Affecting Success

1. Surgeon’s experience
2. Technology used (e.g., Contoura Vision, SMILE, Femto-LASIK)
3. Corneal thickness & eye health
4. Accuracy of pre-surgery measurements
5. Post-operative care compliance

⚠️ Possible Mild Side Effects (usually temporary)

• Glare or halos at night
• Mild dry eyes
• Fluctuating vision for a few weeks

Most of these resolve within 1–3 months after surgery.

🌟 India Advantage

• Advanced laser technology available at top-tier hospitals
• Cost-effective compared to many other countries
• High patient satisfaction and internationally trained surgeons

FAQs from Doctors

👁️‍🗨️ 1. Is LASIK painful?

Doctor says:
No. LASIK is not painful. Numbing eye drops are used before the procedure. You may feel mild pressure but no pain.

📅 2. How long does LASIK take?

Doctor says:
The procedure takes 10–15 minutes for both eyes, and the laser itself works for just 30–60 seconds per eye.

🔁 3. Is LASIK permanent?

Doctor says:
Yes, in most cases. However, natural age-related changes like presbyopia (difficulty seeing up close after 40) may still occur later.

📉 4. Can LASIK fail?

Doctor says:
Rarely. In less than 5% of cases, vision may remain slightly off and require a touch-up (enhancement). Serious complications are extremely rare.

👓 5. Will I still need glasses after LASIK?

Doctor says:
Most people don’t need glasses after LASIK. However, after age 40, you may need reading glasses due to presbyopia.

👨‍⚕️ 6. Am I eligible for LASIK?

Doctor says:
You may be eligible if you:

• Are over 18 years old
• Have stable vision for at least 1 year
• Have healthy eyes with sufficient corneal thickness
• Are not pregnant or breastfeeding

🧴 7. How long is the recovery?

Doctor says:
Initial recovery is 1–2 days, with most vision stabilizing within 1 month. Full healing takes about 3–6 months.

💰 8. Is LASIK covered by insurance?

Doctor says:
Usually not covered since it’s considered an elective/cosmetic procedure. Some plans may offer partial reimbursement.
