Phakic Lens (ICL) Surgery: A Clear Solution for High Power Vision Correction (+10 to -10)

Phakic Lens (ICL) Surgery: A Clear Solution for High Power Vision Correction (+10 to -10)

May 23, 2025

For those with mighty spectacle powers, glasses or even LASIK will not be a good solution. If your power is +10 (farsighted) or -10 (nearsighted), getting a solution that provides clear, comfortable, and stable vision will be challenging. That is where Phakic Intraocular Lens (ICL) surgery comes into play as a risk-free, tried-and-proven solution.

This article will clearly and concisely describe what ICL surgery is, who is a candidate, benefits, recovery time, and cost.

What is Phakic ICL Surgery?

ICL is an Implantable Collamer Lens. It’s a fragile, artificial lens placed within the eye, never displacing the natural lens. That’s why it’s “phakic,” as the natural lens remains intact.

In contrast to LASIK, which physically reshapes the eye (cornea), ICL is placed between the iris (coloured portion of the eye) and the natural lens. It corrects your vision from the inside out—like wearing a contact lens intraocularly perpetually.

Who Is a Suitable Candidate for ICL Surgery?

  • Individuals with high myopia (from -20) or high hyperopia (up to +10)
  • Patients with thin cornea who are not eligible for LASIK
  • Individuals between the ages of 21 and 45 years
  • Patients whose spectacle power is stable for more than one year
  • Healthy individuals with no history of glaucoma, cataracts, or retinal issues

It’s especially suitable for individuals in the range of +10 or -10 who would not like to wear glasses.

Why Not Just Wear Glasses or Have LASIK?

Glasses:

  • Uncomfortable and cumbersome at high powers
  • Give limited peripheral vision
  • Distort images at incredibly high powers
  • Cause cosmetic problems for some

LASIK:

  • Is not an option if your cornea is too thin or irregular
  • Usually not an option for powers over -8 or +6
  • Temporarily changes corneal shape

ICL provides a cut-and-dry solution that doesn’t involve tissue removal or compromise of corneal strength.

Main Advantages of ICL Surgery

  • Appropriate for High Powers: ICL can correct high nearsightedness and farsightedness — better than LASIK or glasses.
  • Natural Vision Preservation: Because your natural lens is not sliced, accommodation (near vision) is retained, particularly in young patients.
  • Increased Optical Quality: Night vision is sharper and more precise with the ICL than with LASIK.
  • Reversible: The ICL may be taken out or replaced down the road if necessary. This is reassuring to patients.
  • No Dry Eye Issues: UCL is not a surface procedure such as LASIK and does not worsen dry eye.
  • Rapid Visual Improvement: Vision improves dramatically in 24 to 48 hours in the majority of patients.

The Procedure: What to Expect

1. Pre-operative Evaluation

  • Your eye measurements (power, corneal thickness, eye length, anterior chamber depth) will be recorded.
  • Eye pressure and retina will be examined.

2. The Surgery (Duration: 10–20 minutes per eye)

  • A small incision is made on the side of the cornea.
  • The ICL is inserted through the incision and placed behind the iris and in front of the natural lens.
  • No stitches are needed; the incision heals on its own.

3. Post-op Recovery

  • You’ll rest for a few hours and can go home the same day.
  • Protective eye shields are usually provided.

Post-operative Recovery Schedule

Timeframe What to Expect
1–2 Days Eyesight improves; minimal pain or sensitivity to light.
1 Week Vision stabilizes further; most normal day-to-day activities return. No swimming or eye rubbing.
1 Month Recovery is complete; last appointments are made to check vision, eye pressure, and lens positioning.
3–6 Months Follow-up observation. Any upgrades or fine-tuning, if required, are planned at this time.

Dos & Don’ts Post-surgery:

  • Follow regular eye drops (antibiotic, anti-inflammatory)
  • Avoid dusty places
  • Don’t rub your eyes
  • Wear UV-blocking sunglasses when outside
  • Schedule follow-up with your eye surgeon as often as ordered

Risks & Precautions

ICL surgery is exceptionally safe with experienced surgeons. However, similar to any surgical procedure, there are a few risks associated with it, which are:-

  • Increased pressure within the eye (rare and managed with medications)
  • Development of a cataract (increased occurrence after the age of 45)
  • Glare or halos at night (rare with current lens design)
  • Risk of infection (nearly zero with proper precautions)

Reduction in these risks is ensured by proper pre-surgery assessment.

Cost of ICL Surgery in India

ACL surgery cost is usually between Rs. 80,000 and Rs. 1,50,000 per eye, depending on:-

  • Model and brand of ICL inserted (astigmatism toric lenses are more expensive)
  • Experience of the surgeon
  • Hospital facilities and follow-up package
  • Place (city metros are more expensive)

Though expensive, long-term benefits and not needing glasses make it a worthy investment in your health.

Is It a Permanent Solution?

Yes, ICL is a permanent correction of vision. However, because the natural lens is not removed from the eye, patients can develop age-related cataracts at some point in their later years — typically after age 50. If this occurs, the ICL can be safely removed when the cataract is removed with cataract surgery and an artificial intraocular lens is placed.

Conclusion

If you have a strong prescription of +10 or -10, and glasses or LASIK are not in your future, Phakic ICL surgery is a safe, effective, and reversible option. It’s a game-changer for most patients, with minimal downtime, enhanced optical clarity, and a high safety profile.
