Preparation Surgery

Proper preparation before eye surgery is crucial to ensure safe outcomes, faster recovery, and minimal complications. While each type of eye surgery has specific protocols, here’s a general guide for pre-surgical preparation:

🩺 1. Preoperative Eye Examination

• Comprehensive eye exam (vision tests, slit-lamp, retina check, corneal mapping)
• Intraocular pressure (IOP) test
• Measurement of eye dimensions (for cataract lens selection)
• Pupillary dilation for retina and optic nerve evaluation
• Discussion of medical history and current medications

💊 2. Medical Evaluation & Blood Work

• Basic health screening (especially if under general anesthesia)
• Blood sugar, blood pressure control for diabetics/hypertensives
• ECG or additional cardiac clearance if you’re over 50 or have comorbidities

⛔ 3. Medication Guidelines

• Stop blood thinners like aspirin or warfarin (only on doctor’s advice)
• Avoid certain herbal supplements (e.g., ginkgo, garlic, ginseng)
• Continue prescribed eye drops (e.g., for glaucoma or inflammation) unless told otherwise

🧼 4. Pre-Surgery Hygiene

• Wash hair and face the day before surgery
• Avoid makeup, creams, or perfumes on the day of surgery
• Wear comfortable clothing (no jewelry or contact lenses)
• Clean eyelids with prescribed eye scrub if instructed

🕑 5. Fasting

• Cataract/retina surgery (local or general anesthesia): Fasting 4–6 hours may be required
• LASIK usually doesn’t require fasting but check with your surgeon

👨‍⚕️ 6. Important Pre-Surgery Instructions

• Arrange transportation (you won’t be able to drive post-surgery)
• Bring a responsible adult companion if sedation is used
• Sign a consent form explaining risks, benefits, and alternatives
• Clarify doubts with your doctor regarding the procedure and post-op care

Procedures

1. Cataract Surgery (Phacoemulsification or Laser-Assisted)

Duration: ~15–30 minutes
Anesthesia: Local or topical

Steps:

1. Eye is numbed using drops or injection
2. Tiny incision made on the side of the cornea
3. Ultrasound probe breaks the cloudy lens (phacoemulsification)
4. Lens fragments removed
5. Artificial intraocular lens (IOL) is implanted
6. Incision may self-seal or need a micro suture

✅ Outpatient procedure with same-day discharge

🔹 2. LASIK Surgery (Laser-Assisted In Situ Keratomileusis)

Duration: ~10–15 minutes
Anesthesia: Numbing eye drops

Steps:

1. Flap creation in cornea using microkeratome or femtosecond laser
2. Flap lifted, and excimer laser reshapes the cornea
3. Flap repositioned, acts as natural bandage
4. No stitches required

✅ Vision improves within 24–48 hours

🔹 3. Glaucoma Surgery (Trabeculectomy or Laser Treatment)

Duration: ~30–60 minutes
Anesthesia: Local, sometimes general

Steps (Trabeculectomy):

1. Surgeon creates a small flap in the white of the eye (sclera)
2. A drainage channel is created to release excess fluid
3. The flap is closed to form a filtering bleb
4. Sometimes a drainage device (tube shunt) is implanted instead

 Helps lower intraocular pressure to prevent optic nerve damage

4. Retina Surgery (Vitrectomy for Retinal Detachment or Diabetic Retinopathy)

Duration: 1–2 hours
Anesthesia: Local or general

Steps:

1. Tiny incisions are made in the white of the eye
2. Vitrectomy: Gel-like vitreous is removed
3. Retina repositioned and reattached using laser, gas bubble, or oil
4. Bubble/oil keeps retina in place while it heals

Post-Procedure

1. General Guidelines (All Eye Surgeries)

✅ Do:

• Use prescribed eye drops regularly (antibiotics, anti-inflammatory, lubricants)
• Protect the eye with a shield or sunglasses
• Keep the eye clean and dry
• Rest well and avoid screen time initially
• Follow-up appointments as scheduled
• Wear dark glasses outdoors to reduce light sensitivity

⛔ Avoid:

• Rubbing or pressing the eye
• Splashing water into the eye
• Dusty environments or smoke
• Strenuous activities, bending, lifting heavy weights
• Driving for a few days
• Using eye makeup (for 1–2 weeks)

👁️ 2. Post-Cataract Surgery Care

• Vision may be blurry for a few days
• Eye shield worn while sleeping (1 week)
• Drops continued for 3–4 weeks
• Avoid washing hair/face for 1–2 days
• Normal activities can resume in 1 week

👓 3. Post-LASIK Surgery Care

• Mild discomfort, burning, or tearing for a few hours
• Vision improves within 24–48 hours
• No rubbing eyes for at least 2 weeks
• Avoid swimming and eye makeup for 2–3 weeks
• Night glare or halos may occur temporarily

🧿 4. Post-Glaucoma Surgery Care

• Redness or tearing is common initially
• Filtering bleb may form and requires monitoring
• Eye pressure checked frequently
• Lifelong follow-up may be required
• May continue with other glaucoma medications

👁️‍🗨️ 5. Post-Retina Surgery Care

• Positioning (face-down) may be required for several days
• No air travel or mountain travel if gas bubble is placed
• Full healing can take weeks to months
• Visual recovery varies depending on severity

Success Rates

Eye surgeries in India are performed with high precision, advanced technology, and at much lower costs than many Western countries — while maintaining world-class outcomes. Here’s a breakdown of the success rates by surgery type:

👁️ 1. Cataract Surgery

• Success Rate: ⭐ 98–99%
• Details: One of the most successful surgeries worldwide. Patients typically experience significant vision improvement within days.
• Complications are rare and treatable when performed by experienced surgeons.

👓 2. LASIK Eye Surgery

• Success Rate: ⭐ 96–98%
• Details: Most patients achieve 20/20 vision or better without glasses.
• Night glare, dry eye, or halos may occur in <5% and often resolve within weeks.

🧿 3. Glaucoma Surgery (e.g., Trabeculectomy, Valve Implant)

• Success Rate: ⭐ 75–90% in lowering intraocular pressure
• Details: Glaucoma surgery doesn’t restore lost vision, but slows or stops further loss.
• Regular follow-up is critical to maintain success over time.

👁️‍🗨️ 4. Retinal Surgery (e.g., Vitrectomy, Retinal Detachment Repair)

• Success Rate: ⭐ 80–90% for retinal reattachment
• Details: Visual recovery depends on the extent of retinal damage and how early surgery is performed.
• Repeat procedures may be needed in some cases.

FAQs from Doctors

1. Is eye surgery painful?

Doctor’s Answer:
No, most eye surgeries are painless. Cataract and LASIK use topical numbing drops, while glaucoma and retina surgeries may use local or general anesthesia. Patients may feel slight pressure or mild irritation post-surgery.

⏱️ 2. How long does recovery take?

Doctor’s Answer:

• Cataract: 1–2 days for vision clarity; full recovery in 3–4 weeks
• LASIK: 24–48 hours for basic vision, 1 week for clarity
• Glaucoma: Recovery varies; improvement seen in 1–2 weeks
• Retina: Depends on severity; may take weeks to months

👓 3. Will I need glasses after surgery?

Doctor’s Answer:

• Cataract: Many patients choose intraocular lenses that reduce or eliminate the need for glasses
• LASIK: Most patients don’t need glasses for distance
• Reading glasses may still be needed after age 40
• Glaucoma/retina patients may still require visual aids depending on condition

🔁 4. Can surgery be repeated if needed?

Doctor’s Answer:
Yes, in some cases:

• LASIK enhancements can be done if vision regresses
• Retina surgeries may need follow-up if re-detachment occurs
• Cataract surgery is usually one-time unless IOL repositioning is required
• Glaucoma surgery might be repeated or supplemented with implants

🦠 5. Are there any risks involved?

Doctor’s Answer:
While complications are rare, potential risks include:

• Infection
• Inflammation
• Over/under-correction (LASIK)
• Retinal detachment (post-cataract in rare cases)
• Elevated eye pressure (post-surgery)

Early detection and follow-up greatly reduce these risks.

🚫 6. What should I avoid after eye surgery?

Doctor’s Answer:

• Rubbing or pressing the eye
• Swimming or heavy workouts
• Dusty environments
• Using eye makeup or contact lenses (for 2–3 weeks)
• Driving (for a few days)

📅 7. When can I resume normal life?

Doctor’s Answer:

• Cataract & LASIK: Within 2–7 days
• Glaucoma & Retina: May take longer depending on healing
  Follow your doctor’s timeline based on your eye condition.
