Cataract surgery is the most performed surgery globally. This guide covers phacoemulsification vs femtosecond laser, monofocal vs multifocal vs toric IOLs, recovery, and costs ($800–$2,000 per eye in India vs $5,000–$8,000 in the US).
What Is a Cataract?
A cataract is a clouding of the natural lens inside the eye, causing blurry vision, glare sensitivity, and faded colours. It's the leading cause of treatable blindness worldwide, affecting nearly everyone over age 70 to some degree. Surgery is the only treatment.
Phacoemulsification vs Femtosecond Laser
| Feature | Phacoemulsification (Standard) | Femtosecond Laser-Assisted |
|---|---|---|
| Incision | Manual, 2.2–2.8mm | Laser-created, precise and reproducible |
| Lens fragmentation | Ultrasound probe breaks lens | Laser softens lens before ultrasound |
| Capsulotomy | Manual circular tear | Laser-created perfect circle (better IOL centration) |
| Outcome difference | Excellent | Marginally better IOL positioning (matters for premium multifocals) |
| Cost premium | Baseline | +$500–$1,500 per eye |
Practical advice: Femtosecond laser cataract surgery is worth the premium mainly when implanting multifocal or toric IOLs, where precise capsulotomy and IOL positioning maximise results.
IOL Options
| IOL Type | Distance | Intermediate | Near | Best For | Extra Cost (India) |
|---|---|---|---|---|---|
| Monofocal | ✓ | ✗ | ✗ (need reading glasses) | Budget-conscious, drivers | Included |
| Multifocal | ✓ | ✓ | ✓ | Glasses-free vision | +$400–$800 |
| EDOF (Extended Focus) | ✓ | ✓ | ✓/partial | Less halos than multifocal | +$350–$700 |
| Toric | ✓ (corrects astigmatism) | ✗ | ✗ | Astigmatism >1D | +$200–$500 |
| Toric Multifocal | ✓ | ✓ | ✓ | Astigmatism + glasses-free | +$600–$1,000 |
Recovery Timeline
- Day 1: mild discomfort, light sensitivity; wear protective shield at night
- Week 1: vision already significantly improved; use antibiotic + steroid drops
- Week 2–4: final prescription stabilises; new glasses (if monofocal) prescribed at 4 weeks
- Month 1–3: night-time halos with multifocals typically fade as the brain adapts
Cost Comparison (Per Eye)
| IOL Type | India | Thailand | USA |
|---|---|---|---|
| Monofocal (phaco) | $800–$1,200 | $2,000–$3,000 | $3,500–$5,000 |
| Multifocal (phaco) | $1,200–$2,000 | $3,000–$4,500 | $5,000–$7,000 |
| Femto + Multifocal | $1,800–$2,800 | $4,000–$6,000 | $6,000–$8,000 |
