ICL Eye Surgery – Implantable Collamer Lens for Long Term Corrections

Posted on October 4, 2017

If you wear corrective eyewear such as glasses or contact lenses and would like to be free of the encumbrance, there are several options that provide permanent vision correction. Although LASIK surgery is the most well-known method to correct vision, there are other options for people who may not be candidates for LASIK.

ICL Eye Surgery DelhiImplantable Collamer Lenses (ICL) offer a permanent treatment for myopia, or short-sightedness. Implantable lenses, also called phakic lenses, are clear lenses that are implanted over the natural lens of the eye. The natural lens of the eye stays in place. The ICL focuses light on the retina to promote clear vision. People who opt for implantable lenses often get better vision outcomes than from laser surgery.

Intraocular lenses have been used for vision correction for approximately 50 years, usually in association with cataract surgery. People have cataract surgery because the natural lens of the eye becomes clouded. The natural lens is removed and a new lens is inserted to correct vision. An eye that has had the natural lens removed is called aphakic. Over the past 15 years, advances in intraocular lens surgery now allow implants over the natural lens to correct refractive errors.

The LASIK technique, in contrast, modifies the cornea to produce better vision. The cornea is the clear, rounded, outermost portion of the eye. It plays a major part in vision acuity. In LASIK surgery, a small flap is cut on the surface of the cornea. A laser is then used to make microscopic incisions that modify the cornea’s shape and smooth its contours.

The professional staff at Eye7 Chaudhary Eye Centre in New Delhi specialise in corrective eye surgery, including several types of LASIK procedures, ICL implants and cataract surgery. Dr. Sanjay Chaudhary, chief executive and head surgeon, founded the centre and oversees its operation.

At Eye7 Hospital, your vision and the condition of your eyes are evaluated. Recommendations for treatment are made based on the vision outcome you desire, your budget and your health. Because each eye is unique, the shape, health and dimensions of your eye will determine whether you are a candidate for LASIK or would get better results from another procedure. Many people who are not able to have LASIK surgery get excellent results with ICLs.

Dr. Chaudhary has pioneered several types of LASIK treatment, has won awards for his specialisation in ICL implants and has been in the forefront in introducing and refining other surgical techniques to correct vision. He is one of the most well-known eye surgeons in Delhi.


Types of Implantable Collamer Lenses

There are two major types of ICLs: toric lenses and spherical lenses. Toric lenses are used to correct astigmatism as well as short-sightedness or long-sightedness. Astigmatism is caused by an irregularly shaped cornea. Instead of being rounded, the cornea is oblong. Light entering the cornea refracts in multiple points of focus instead of a single point. People with astigmatism may experience glare from lights, double vision or blurred vision. Vision correction with toric lenses involves not just correcting short- or long-sightedness. Toric ICLs also compensate for the shape of the cornea.

Toric lenses are designed with different powers of correction built into the meridians of the lens. Meridians are imaginary lines that are arranged in radial, one-degree increments and pass through the centre of the pupil. Meridians are used to describe the curvature of the cornea. When the curvature is irregular, ophthalmologists use meridians to evaluate the different curvatures and construct a corrective lens that evens out the irregularity.

A toric contact lens, which is positioned on the surface of the eye, is designed to rotate so that the corrective powers of the meridians sit properly on the eye. An implanted lens is fixed and does not rotate. Implanted toric lenses are constructed so that the meridians are properly placed permanently in the eye. Toric lenses correct cylinder as well as spherical refractive errors.

Spherical lenses correct close-sightedness or long-sightedness only, not cylinder corrections as toric lenses do. The attending ophthalmologist will evaluate the refractive errors of each eye and recommend an appropriate lens. If you have astigmatism in only one eye, an implantable toric lens may be recommended for that eye and a spherical lens for the other.


About Visian Implantable Collamer Lenses

At Eye7 Hospitals, only the Visian implantable collamer lens made by Staar Surgical of Switzerland is used. Visian ICLs are approved by the U.S. Food and Drug Administration. Although other manufacturers also make implantable collamer lenses, the Visian brand is reliable and performs well. They are made of collagen, a naturally occurring substance that is compatible with the human body. Collamer has been used for many years as an implantable material in the eye.

The Visian ICL also contains an ultraviolet ray filter to protect the eyes from the harmful effects of sunlight. The newest version of the Visian ICL allows the aqueous humour, the natural fluid within the eye, to flow through a hole in the lens. The flow of fluid enhances the natural environment around the lens.

The lens is implanted in front of the natural lens of your eye just behind the iris. The micro-thin, clear lens cannot be felt and does not require any maintenance. Unlike a contact lens that is placed on the front of the eye and is removable, the ICL lens is permanent. However, the procedure is reversible and the lens can be surgically removed.

The implant surgery is done on an out-patient basis and takes less than an hour to perform. The implant generally has very few side effects and is usually without complication. Severe complications occur in less than 1 percent of patients. However, as with any surgery, there are risks. Most are treatable.

Risks include infection, increased intraocular pressure or damage of the natural lens. In rare instances, vision can be over-corrected or under-corrected. In these situations, the ICL can be replaced, or further vision correction, such as contact lenses, glasses or refractive surgery, can be done. Your ophthalmologist will discuss the potential risks and complications with you before treatment.


Visian Implantable Collamer Lenses Compared to LASIK Corrective Surgery – LASIK vs ICL

Many people request LASIK surgery to correct vision problems. LASIK can be used to correct short-sightedness, long-sightedness and mild astigmatism. However, certain conditions and health requirements must be met to be a candidate for LASIK surgery. The cornea must be of a certain thickness and shape. If you have extreme close-sightedness or astigmatism, LASIK may not be appropriate.

If LASIK is not suitable to correct the refractive errors of your eyes, Visian implantable collamer lenses may be a better alternative. Unlike LASIK, which surgically alters the shape and contours of the cornea, an ICL does not modify the eye. A small incision is made to insert the implant between the natural crystalline lens of the eye and the iris. The implant is folded when inserted. Once in the eye, the lens unfolds and is properly positioned. The incision heals on its own, usually without stitches. There is no alteration of the cornea. There is no corneal weakening, which can happen with LASIK.

The procedure has been used internationally since 1995, and since 2005 in the U.S. An ICL is indicated if you have the following conditions:

  • Dry eyes.
  • Keratoconus or other cornea conditions that are not suitable for LASIK treatment.
  • Thin cornea.
  • Astigmatism with a cylinder correction of more than 3.5 dioptres.
  • Short-sightedness between –3.0 dioptres and –20.0 dioptres.

In addition you must:

  • Be more than 18 years old.
  • Have had a stable correction for about 12 months.
  • Not have any eye disease.
  • Not be pregnant.

If you are diabetic, you may still be eligible for an ICL implant. Your eye doctor will review your health conditions and recommend appropriate treatment.

People who undergo an ICL procedure notice vision changes almost immediately. In clinical studies, 93.6 percent had 6/12 vision or better without glasses after one year. In treatment of extreme short-sightedness, 72.2 percent of those who had a Visian ICL implant in one eye and LASIK surgery in the other had better quality of vision with the implant. People with ICL implants generally do not see glare or halos around lights.


Cost of Visian Implantable Collamer Lens Surgery in Delhi

There is not a preset fee for a Visian lens. The cost depends on your prescription, your doctor and where you have the procedure done. Visian ICL costs more than LASIK surgery. Costs factored into the procedure include:

  • Thorough exam and presurgical screening to ensure proper fit and prescription.
  • Custom-made lens of high-quality, proprietary material.
  • Hospital and surgeon’s fees.
  • Post-procedure follow-ups.

In an overview of costs in New Delhi, ICL implants range in price from approximately INR 80,000 to INR 1,25,000 per eye. The cost of Visian implantable collamer lenses may seem high at first glance. However, when you consider that the Visian ICL implant is permanent, you may save money over the long term.

When you compare costs of an implant to eye glasses, you may spend the same or more over a period of 10 years for the glasses. If you have a strong prescription, you may opt for thinner lenses, which cost more. When you include UV, anti-glare and anti-scratch coatings, the price of spectacles increases dramatically. Frames add to the price. A single pair of spectacles can easily cost a lot of money. You can easily end up spending as much as the surgery over a period of 10 years.

After an ICL implant, 95 percent of the patients do not need glasses or contact lenses. If you are in the 5 percent of people who may need external vision aids after an ICL implant, there are ways to achieve better vision acuity. If you are over 45 years old, you may need reading glasses.

After an initial consultation to evaluate your unique eye condition, Dr. Chaudhary can better inform you about the cost for your situation.
