You may hear terms such as Phakic IOL, ICL or IPCL during this discussion. These names can sound complicated, but the basic idea is quite simple.

Instead of reshaping the cornea with a laser, a specially designed lens is placed inside the eye to help correct the spectacle power.

Why Might Someone Be Unfit for Laser Vision Correction?

Laser procedures such as LASIK, SMILE and PRK reshape the cornea to correct eye power.

Before recommending them, the ophthalmologist checks several factors, including:

• corneal thickness

• corneal shape

• spectacle power

• stability of the eye power

• dry-eye condition

• overall eye health

Some people may have a very high spectacle power, while others may have a cornea that is too thin or has an unsuitable shape for safe laser correction.

Significant dry eye or certain corneal conditions may also influence whether laser treatment is appropriate.

This is why refractive surgery should never be decided based only on your spectacle number.

What Is a Phakic IOL?

A Phakic Intraocular Lens, or Phakic IOL, is an artificial lens placed inside the eye while your natural lens remains in place.

This is different from cataract surgery.

During cataract surgery, the natural lens of the eye is removed and replaced with an artificial lens. In a phakic IOL procedure, the natural lens is not removed.

The additional lens works together with your natural lens to correct the refractive error.

Phakic IOLs are mainly considered in selected patients who want to reduce their dependence on glasses but are not suitable for corneal laser procedures.

What Is an ICL?

ICL stands for Implantable Collamer Lens.

It is one type of phakic intraocular lens.

The lens is placed inside the eye, usually behind the coloured part of the eye called the iris and in front of the natural lens.

Because the cornea is not reshaped in the same way as LASIK or PRK, ICL may be considered for certain patients with high powers or unsuitable corneal measurements.

However, being unsuitable for LASIK does not automatically mean that everyone can have an ICL. The eye still needs to meet specific requirements.

What Is IPCL?

IPCL stands for Implantable Phakic Contact Lens.

Like an ICL, an IPCL is an implantable lens placed inside the eye while the natural lens remains intact.

Its purpose is also to correct refractive errors without removing corneal tissue.

Both ICL and IPCL belong to the broader category of phakic intraocular lenses.

The exact lens considered depends on factors such as the patient's eye measurements, power, available lens options and the surgeon's assessment.

Who May Be Considered for a Phakic IOL?

A phakic lens may be considered in selected patients who:

• have moderate to high spectacle power

• are not suitable for LASIK, SMILE or PRK

• have a cornea that may not be appropriate for laser correction

• have relatively stable eye power

• have a clear natural lens

• meet the required internal eye measurements

The ophthalmologist also checks the health of the cornea, retina, natural lens and other parts of the eye before recommending surgery.

What Tests Are Done Before ICL or IPCL Surgery?

Phakic IOL surgery requires detailed planning.

The ophthalmologist may evaluate:

• spectacle power

• corneal shape and thickness

• depth of the front part of the eye

• size and anatomy of the eye

• eye pressure

• retina

• natural lens

• the number and health of corneal endothelial cells

These measurements help determine whether there is enough space inside the eye for the implantable lens and whether the procedure may be suitable.

How Is This Different From LASIK?

The main difference is where the correction takes place.

In LASIK, SMILE or PRK, the cornea is reshaped.

With an ICL or IPCL, the cornea is not reshaped to the same extent. Instead, an artificial lens is placed inside the eye to provide the required correction.

This can make phakic IOLs useful for certain patients who are not suitable for laser treatment.

However, it is still an intraocular surgical procedure, which means it has its own possible risks and requires careful patient selection.

Are There Risks With ICL or IPCL?

Yes. Like any surgery inside the eye, phakic IOL procedures can have potential complications.

Depending on the individual eye, possible concerns may include:

• infection

• inflammation

• changes in eye pressure

• effects on the cornea

• cataract formation later in life

• need for further treatment or lens adjustment in selected cases

These complications are not expected in every patient, but they are important to discuss before making a decision.

No refractive procedure should be presented as risk-free.

Can an ICL or IPCL Make You Completely Free From Glasses?

Many patients choose phakic IOL surgery because they want to reduce their dependence on spectacles or contact lenses.

However, complete freedom from glasses cannot be guaranteed.

A small amount of power may remain, and vision can also change naturally with age.

After around the age of 40, near vision may gradually become more difficult because of presbyopia, even if the distance power has been corrected.

What If You Are Not Suitable for Laser or Phakic IOL?

Sometimes, after detailed testing, the safest option may still be glasses or contact lenses.

Depending on age and eye condition, other lens-based procedures may also be discussed in selected patients.

The goal of refractive surgery planning should not be to make every patient undergo a procedure. It should be to identify whether there is an option that is appropriate for the individual eye.

Phakic IOL Evaluation at Pixel Eye Hospital

If you have been told that you are not suitable for LASIK or another laser vision-correction procedure, it may be useful to understand whether an implantable lens option is appropriate for your eyes.

At Pixel Eye Hospital in Kukatpally and Sanath Nagar, Hyderabad, patients can consult Dr. Abdul Rasheed and Dr. Krishna Poojita for refractive surgery evaluation, including assessment for laser procedures and phakic lens options such as ICL or IPCL where appropriate.

The decision is made after checking the cornea, spectacle power, internal eye measurements and overall eye health.

Final Thoughts

Being unsuitable for LASIK does not necessarily mean the end of your vision-correction options.

For selected patients, phakic IOLs such as ICL or IPCL may provide an alternative because they correct the spectacle power using an implantable lens rather than reshaping the cornea.

However, these procedures are not suitable for everyone.

A detailed eye evaluation is essential to understand whether laser correction, an implantable lens or simply continuing with glasses or contact lenses is the most appropriate choice.

If you are exploring vision correction in Hyderabad and have been told that LASIK may not suit your eyes, you can visit Pixel Eye Hospital at Kukatpally or Sanath Nagar for a detailed assessment and discussion of the available options.
