The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. Together with the lens, the cornea refracts light, accounting for approximately two-thirds of the eye's total optical power. In humans, the refractive power of the cornea is approximately 43 dioptres. While the cornea contributes most of the eye's focusing power, its focus is fixed. The curvature of the lens, on the other hand, can be adjusted to "tune" the focus depending upon the object's distance. Medical terms related to the cornea often start with the prefix "karat-" from the Greek word, horn.
Our institute is now “HOTA certified” (HOTA - Human Organ Transplant Act). We are now performing Corneal Transplantation with Successful results. The Department is managed by Dr. Sonal Vyas (M S, Fellow cornea LVPEI )
We have a Dedicated Cornea Clinic with the following facilities:
IPCL / ICL Implant in East Raipur – If your glass power is too high, or if your corneas are too thin, then you are probably unsuitable for LASIK Treatment or even EPI-LASIK. Shreya Eye Centre Delhi offers you a safe and effective alternative that is IPCL/ ICL Implant in Raipur.
The Phakic IOL (IPCL/ICL) is indicated for patients unsuitable for LASIK with extremes of myopia (near-sightedness), hyperopia (far-sightedness) and/or astigmatism (cylindrical powers).
They are designed to correct visual problems much the same way as an external contact lens. Unlike external contact lens, Phakic IOL IS placed inside the eye behind the iris (colored part of the eye) and in front of the eye’s natural lens. Unlike LASIK, the Phakic IOL (IPCL/ICL) is a reversible procedure
It is an artificial lens made from material similar to the type used for intraocular lenses currently being implanted in cataract surgery that is placed inside your eye in addition to your natural lens.
The Phakic IOL (IPCL/ICL) is a very thin, foldable lens, which is inserted into the eye through a tiny sutureless , self-sealing corneal microincision during a 10-15 minutes procedure under topical anesthesia (anesthesia by eye drops). Each Phakic IOL is specially designed and custom-made to fit the patient’s own unique anatomy. It lies behind the iris and in front of the lens, without touching the central lens. The ICL is reversible and can correct near-sightedness, far-sightedness and astigmatism. This lens is not visible to others , as it is placed behind the Iris.
Because every eye is different, your surgeon must choose the best treatment for your specific condition. The Phakic IOL (IPCL/ICL) is capable of correcting almost all types of refractive errors, including very high myopia & astigmatisms. Many patients who are declared unfit for conventional laser treatment (LASIK, PRK etc.) can also benefit from Phakic IOL (ICL/IPCL)
Implantable contact lenses are best suited for patients with high nearsightedness or high farsightedness with problems wearing contact lenses. More specific guidelines of Phakic IOL eligibility could include:
Extreme Myopia (nearsightedness) >-8 Diopters.
Extreme Hyperopia (farsightedness) >+6 Diopers.
Even low to moderate Myopia – if cornea is too thin to have safe LASIK or even EPI-LASIK
Older than 21 years with a stable refraction for 2 years or more and not pregnant
Dry eyes or large pupil
Contraindications for Laser refractive surgery
Phakic IOL (IPCL/ICL) work-up and treatment at Shreya Eye Centre is performed by our experienced staff and surgeons. An initial consultation will confirm suitability.
Each patient then goes through a comprehensive series of eye tests and examinations (including manifest, cycloplegic and post-mydriatic refraction, Pentacam, Optical Biometery, W-to-W diameter, and thorough retina check-up) before consulting with the surgeon to discuss and plan the specifics of personal vision correction.
If one decides to go ahead with the treatment, the lenses will be made to the exact specifications and will be ready in 1-2 weeks. If you wear contact lenses, you will be required to stay off them prior to your check-up (soft lenses for 5 days and rigid lenses for 2 weeks preferably).
As part of the pre-operative work-up your surgeon may perform YAG laser iridotomy before the actual procedure, which consists of making a hole in your colored portion of the eye (iris) to help ensure that intraocular fluid does not build up behind the Phakic IOL (IPCL/ICL). Though with newer generation Phakic IOL’s with a hole in center of IOL it’s not mandatory to do YAG laser iridotomy
Prior to the Phakic IOL (IPCL/ICL) procedure you will be started on pre-operative medication including antibiotic drops, as per the surgeon’s requirements. The PIOL implantation procedure is performed in a specialist ophthalmic theatre. Topical drops anesthetics will be used to numb the eye.
The lens is inserted through a micro incision in the side of the cornea and sits in front of the eye’s natural lens, just behind the Iris. Antibiotic and anti-inflammatory drops are then administered to avoid infection and the whole procedure takes around 10-15 minutes. As a precautionary measure, the lenses are implanted one at a time, with gap to 3-5 days for second eye.
Postoperatively patient need to take precautions for 1 week. Most patients can get back to routine work after 1-2 weeks
You will be able to go home on the same day and it is preferable that you have someone to accompany you.
You are free to leave the clinic as soon as you feel able, with protective glasses over the eye .
Although you may see some improvement in your vision as early as the first postoperative day but visual recovery may take 1-2 weeks to stabilize.
You will be able to return to normal activities within 2-3 days following surgery and should be able to drive and be back to work within two weeks of the procedure.
You will need to be seen again by your surgeon on the day after surgery. Post-operative visits are required after one and 3 weeks, then as directed by the surgeon.
Though most patients are suitable for Phakic IOL implant, some may not be suitable due to factors like inadequate Anterior chamber depth, ocular co-morbities like Cataract, Glaucoma, retinal diseases etc.
Though Phakic IOL (IPCL/ICL) is very safe and results are very satisfying, the results of surgery cannot be guaranteed.
Some patients may need glasses with minor power for sharpest vision, for night driving or other activities performed in low light, and for prolonged reading etc.
Phakic IOL’s are designed to provide as close to normal vision as possible. People with normal distance vision benefit from wearing reading glasses for near work at some stage in their 40s. Phakic IOL (IPCL/ICL) patients experience this aging change just the same as normal people.
Though this procedure is considered to be very safe, the standard risks of any intraocular surgery are possible .
There is a small risk of infection but this is minimized by the full sterile theatre conditions. There is also a small possibility of damage to the structures of the eye, which could lead to cataracts, glaucoma, retinal complications, corneal decomposition and rejection.
Severely short-sighted people often have other eye problems such as damaged retinas and progressively deteriorating eyesight. The ICL cannot help or stop these associated conditions. In the event of complications, lens implants are potentially reversible.
No procedure can be risk-free. Ultimately, the patient needs to make up their mind about the risk/benefit balance for the various options available to them to correct their high myopia or high hyperopia. Some patients need surgical correction of their severe focus error for safety reasons.
Theoretically, the proximity of the ICL to the iris and lens raises the possibility of late onset lens opacities or pigment dispersion. Both these rare but potential problems are much more easily fixed than corneal complications following LASIK surgery. Current evidence supports Phakic IOL (IPCL/ICL) as being a very effective and safe option for these patients.
The Phakic IOL (IPCL/ICL) is designed to be placed in your eye and remain there permanently, but with increasing age if you develop a cataract significant enough to cause visual problems, then cataract removal with intraocular lens implantation can be done with removal of the Phakic IOL (IPCL/ICL).
The Phakic IOL (IPCL/ICL) is tiny and soft – It can be folded so small that it can be injected painlessly into your eye in seconds through a tiny opening in your cornea so that it unfolds into position in the liquid between your iris and your natural lens and is easily accepted by your body
The Phakic IOL (IPCL/ICL) is invisible – It is placed inside your eye, rather than on the surface. The lens is invisible. The only way that you or anyone else will know that it is there, is the improvement in your eyesight.
Phakic IOL (IPCL/ICL) is removable – the lens is meant to remain permanently in the eye. However, it can be removed if necessary, since the lens does not alter any structures within the eye or the cornea.
The Phakic IOL (IPCL/ICL) works beyond the limits of laser treatment – the Phakic IOL (IPCL/ICL) is useful in cases beyond the limits of laser treatment (high minus and plus spectacle powers) and is the treatment of choice if you have thin corneas, dry eyes, or large pupils
The Toric Phakic IOL (IPCL/ICL) treats two vision disorders in one procedure – the toric IPCL/ICL corrects you nearsightedness as well as your astigmatism in one single procedure. Each lens is custom made to meet the needs of each inidual person.
The Phakic IOL (IPCL/ICL) provides high patient satisfaction – They provides high quality of vision, and is a highly precise and predictable treatment providing exceptional patient satisfaction.
Surgeons around the world have made the Phakic IOL (ICL/IPCL) their procedure of choice more than 65,000 times – not only for their patients, staff and family, but even for themselves.
Q. Am i a candidate for the Phakic IOL (IPCL/ICL)?A. Yes, if you have nearsightedness, and / or astigmatism and no eye disease. Phakic IOL (IPCL/ICL) for farsightedness is also available.
Q. What are the advantages of the Phakic IOL (IPCL/ICL)?A. Lens is small, foldable, and injected through a tiny, pain free, self healing incision in your eye. Phakic IOL (IPCL/ICL) provides highly predictable outcomes, excellent quality of vision and can be removed if necessary.
Q. How quickly can i go back to my daily routine & activities?A. Due to the quick recovery after this treatment, you can leave the centre after a couple of hours. You will be able to enjoy your new sight almost immediately and go back to your active lifestyle. Your surgeon will give you detailed advice.
Q. What if my vision changes?A. Though unlikely, if during your annual eye exam a major change in your vision is observed, the Phakic IOL (IPCL/ICL) can be removed or replaced. With the Phakic IOL (IPCL/ICL) you can still wear glasses or contact lenses if necessary. The lens does not treat presbyopia or eliminate the need for reading glasses due to age. Now Presbyopic Phakic IOL (IPCL/ICL) are also available, which can correct presbyopia along with myopia or hyperopia, thus reducing dependency on reading glasses also
Q. What is the long-term experience with Phakic IOL (IPCL/ICL)?A. The ICLtm has been available internationally for over 12 years. More than 65,000 lenses have been implanted since then.
The ICL thus provides a high quality of vision, and is a highly precise and predictable treatment providing exceptional patient satisfaction for patients unsuitable for lasik
