Implantable Collamer Lens (ICL) surgery is a vision correction procedure that involves implanting a specialized lens inside the eye to correct refractive errors like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.

Unlike laser-based surgeries such as LASIK or SMILE, ICL surgery does not involve reshaping the cornea. It is an ideal option for patients who have high refractive errors or thin corneas and are not candidates for laser surgeries.

"At Mahajan Eye Centre, we have more than a decade of experience with different types of phakic IOL implantation (ICL/ IPCL). We are proud to be one of the earliest to start the procedure in the area along with one of the highest number of procedures done in the area."

There are several advantages of Phakic IOL Procedures:

  • Corrects moderate to High refractive errors (including powers otherwise not correctable by Laser Vision Correction).
  • Provides sharper and clearer vision than glasses or contact lenses (better quality of vision than laser vision correction for higher prescriptions).
  • Does not remove corneal tissue, preserving the natural structure of the eye (Suitable of patients with thin corneas who are otherwise unfit for Laser Vision Correction)
  • Can be removed or replaced if necessary, making it a reversible procedure. (unlike Laser Vision Correction)
  • No increase in Dry Eye Syndrome
...
  • Patients aged between 21–45 with stable vision for at least 1 year.
  • Individuals with moderate to high myopia (typically greater than -6.00 diopters) or hyperopia.
  • Patients with thin corneas who are not suitable for LASIK or SMILE.
  • Those who want a reversible vision correction option.
  • Individuals looking to reduce or eliminate dependence on glasses or contact lenses.

ICL surgery involves implanting a small, flexible lens made from collamer (a biocompatible material) inside the eye. This lens is inserted between the natural lens and the iris, where it works with the natural eye structures to correct vision.The procedure is minimally invasive and the lens is implanted through a small opening allowing for a quickprocedure and recovery time.

1. Pre-Surgical Assessment:
  • Your doctor will perform a series of standard tests to measure your eye’s unique characteristics for the procedure. A detailed eye examination, including the Pentacamfrom Oculus, will assess your corneal thickness, eye shape, and overall eye health.
...
  • Once your doctor determines that the ICL is a good option for you, they will educate you about the procedure and what to expect both during and after the procedure.Measurements are taken to customize the ICL for your eye.
...

2. Surgery Day:
  • The procedure is done on day-care basis and typically takes about 10-20 minutes. You will be will administered eye drops to dilate your pupils as well as anesthetize your eyes.
  • A small incision is made in the cornea, through which the ICL is gently folded and inserted behind the iris, in front of the natural lens.
...
  • The lens unfolds and is positioned correctly to correct your vision.
  • Since the incision is so small, stitches are usually not required, and the eye heals quickly.
...

3. Post-Surgery Recovery:
  • Recovery Time: Most patients experience improved vision within the first 24 hours. Full recovery may take a few days to a week.
...
  • Follow-Up: Regular follow-up appointments will be scheduled to monitor healing and ensure the ICL/IPCL is correctly positioned.
  • Long-Term Results: ICL/IPCL lenses are designed to last a lifetime, offering stable and long-term vision correction
...

In addition to the internationally known ICL lenses from STAAR Surgical, there is an excellent Indian-made alternative known as IPCL (Implantable Phakic Contact Lens). The IPCL, manufactured by Care Group India, offers a cost-effective solution without compromising quality, making it an accessible option for more patients.

Key Features of IPCL:

  • High Customization: Like the STAAR ICL, IPCL lenses are custom-made based on individual eye measurements, ensuring the best fit and optimal vision correction.
  • Range of Corrections: IPCL is available to correct a wide range of refractive errors, including high myopia, hyperopia, and astigmatism.
  • Affordability: IPCL lenses are more cost-effective compared to international alternatives, making advanced vision correction accessible to a broader population in India.
  • Material: Made from biocompatible material similar to collamer, which ensures the lens is well tolerated by the eye, causing no adverse reactions.

Advantages of IPCL:

  • Safe and effective for patients with high refractive errors.
  • No corneal tissue removal, making it a suitable option for patients with thin corneas.
  • Fast recovery with minimal discomfort.
  • Lower cost compared to imported ICLs, while offering the same level of precision and safety.

While LASIK and SMILE reshape the cornea using lasers to correct vision, ICL/IPCL surgery involves placing a lens inside the eye, leaving the cornea untouched. This offers several advantages for patients with higher degrees of refractive error, thin corneas, or dry eyes.

  • Corneal Integrity: ICL/IPCL surgery preserves the natural shape and thickness of the cornea, making it a safer option for patients with thin or irregular corneas.
  • Reversibility: Unlike laser surgery, where corneal tissue is permanently removed, the ICL/IPCL can be removed or replaced if necessary.
  • Higher Corrections: ICL/IPCL is capable of correcting higher refractive errors that might not be treatable with LASIK or SMILE.

At Mahajan Eye Centre, we use state-of-the-art technology for refractive surgery to ensure precise, safe, and effective outcomes. Below are the key devices utilized in our procedures.

...

Zeiss IOL Master 700 – Precision Optical Biometry

The Zeiss IOL Master 700 is the gold standard in optical biometry. It provides extremely accurate measurements of the eye, which are critical for selecting the right intraocular lens (IOL) and used for all lens based refractive surgery procedures including ICL and RLE/ PRELEX. The machine uses swept-source OCT (Optical Coherence Tomography) to map the entire length of the eye, ensuring optimal lens positioning and power calculation.

Advantages

  • Enhanced precision in preoperative measurements and IOL selection reduces the risk of post-operative refractive errors, ensuring better visual outcomes.
  • It provides a full-length scan of the eye, which helps detect any issues early, allowing for a more customized surgical plan.
  • Suitable for complex cases, such as eyes with high astigmatism or previous surgeries like LASIK.
  • Best data capturing power for accuracy even in advanced cataracts

Oculus Pentacam – Gold Standard Tomography

The Oculus Pentacam is an advanced diagnostic device that provides comprehensive imaging of the cornea and anterior segment, crucial for pre-surgical evaluations and post-operative monitoring. The device is first of its kind to be capable of detailing posterior corneal surface amking it gold standard for decision making in laser refractive procedure.

Advantages

  • Detailed Corneal Analysis: Measures corneal thickness, curvature, and elevation to detect abnormalities like keratoconus or irregular astigmatism.
  • 3D Anterior Segment Imaging: Offers a complete view of the eye's front structures, aiding in customized treatment planning.
  • Safety Screening: Helps identify patients who may not be suitable candidates for refractive surgery, ensuring safe and effective outcomes.
