Implantable collamer lenses (ICLs), also known as phakic IOLs, correct vision in much the same way that external contact lenses do, except ICLs are surgically placed inside the eye, where they permanently improve vision. Phakic, from the Greek word "phakos," for lens, refers to artificial lenses that operate in conjunction with the patient's natural lenses.

While ICLs function in almost exactly the same way as contact lenses that sit atop the eye, they are also similar to intraocular lenses (IOLs), which are used during cataract surgery to replace the eye's natural lens after it has been fragmented and removed. However, during ICL surgery, the natural lens is kept in the eye and works with the implanted lens to correct vision.

ICLs are inserted through tiny incisions in the cornea and placed behind or in front of the iris (The colored part of the eye) and in front of the natural lens. These thin, pliable lenses can serve as an alternative to laser eye surgery procedures such as LASIK and are often used to correct conditions that laser procedures may be unable to correct, such as extreme myopia. The ICL procedure produces little to no discomfort for the patient and has a 95 percent average success rate.

The EVO procedure is minimally invasive, and the lens is implanted through a small opening allowing for a quick procedure and recovery time.

With over 1,000,000 lenses implanted worldwide and 20+ years of premium ICL performance, EVO is quickly becoming a vision correction procedure of choice for many people around the world.

1. Exactly where is the EVO Visian ICL placed in the eye?
--- EVO Visian ICL is placed behind the iris and in front of the eye’s natural lens so it’s undetectable to any observers.

2. What is the history of the ICL?
--- Over the past 20 years, ICLs have been implanted in over 1,000,000 eyes worldwide.

3. Why is Collamer such a great material for the eye?
--- The Collamer lens is soft, pliable, biocompatible and offers UV protection.

4. Are patients happy with the EVO Visian ICL?
--- Of patients having the EVO Visian ICL procedure, 99.4% would choose to have the EVO Visian ICL procedure again.

5. Can the EVO Visian ICL be removed in the future if my prescription changes?
--- Yes! The EVO Visian ICL offers treatment flexibility. If your vision changes dramatically, the lens can be removed.

6. How long can EVO Visian ICL stay in the eye?
--- The EVO Visian ICL is designed to stay in your eye permanently but can be removed to keep pace with advancing technology and your future needs.

7. Does the procedure remove tissue from my eye?
--- No, the EVO Visian ICL is inserted gently in the eye with no removal of corneal tissue.

8. Can the EVO Visian ICL dry out or get dirty like a contact lens?
--- The EVO Visian ICL avoids such problems experienced with traditional contact lenses. It is designed to remain in place inside the eye, without maintenance. A routine, annual visit with an eye doctor is recommended to make sure everything remains safe and effective.

9. How the EVO Visian ICL corrects Nearsightedness and Astigmatism?
--- EVO Visian ICL functions to focus light properly back onto the retina in a similar way glasses and contact lenses do. The EVO Visian ICL is placed into a space of the eye directly behind the iris (the colored part of the eye) and in front of the natural lens. In this position, the EVO Visian ICL functions to focus light properly onto the retina helping create clear distance vision.

Before considering EVO Visian ICL surgery you should have a complete eye examination and talk with your eye care professional about EVO Visian ICL surgery, especially the potential benefits, risks and complications. You should discuss the time needed for healing after surgery.

Glaucoma is the leading causes of irreversible blindness worldwide. In India alone, it affects around 12 million people; India is projected to become the world capital of glaucoma by 2020. The sight loss caused by glaucoma is progressive and, unlike cataract, is irreversible. Fortunately, early diagnosis and treatment can prevent blindness from glaucoma.

WHAT IS GLAUCOMA?

Glaucoma is a disease of the nerve In which there is damage to the optic nerve (nerve for vision) vision caused by increased pressure in the eye.

HOW DOES GLAUCOMA OCCUR?

The inside of the eye contains a fluid, which is being produced and drained out of the eye constantly. It is drained through a sieve like structure situated at the angle between the transparent cornea and the brown coloured iris. When the drainage mechanism becomes ineffective, the pressure in the eye (intra-ocular pressure) increases leading to optic nerve damage which is called glaucoma.

WHAT ARE THE EFFECTS OF GLAUCOMA?

Glaucoma can lead to permanent loss of vision. Initially, the loss of vision starts from periphery and progressively affects the central vision. The central visual acuity is affected only in the advanced stage.

Progressive visual field loss with corresponding damage to optic nerve head in a patient suffering from GLAUCOMA.

INSTRUMENTS USED FOR DIAGNOSIS OF GLAUCOMA

• Medical management of glaucoma
• Lasers- Peripheral Iridotomy, Trabeculoplasty, Iridoplasty
• Sugeries - Trabeculectomy (TRAB), Glaucoma drainage devices (Ahmed Glaucoma Valve -AGV)
• Cryopexy/DLCP for Painful Blind Eye due to Glaucoma

The Paediatric Ophthalmology service at PC SHARMA EYE HOSPITAL was started with a noble aim of bringing back a smile to a child’s face. Over the years the Hospital has grown to be a major referral centre for paediatric eye disorders. At present, this service involves diagnosis and management of various aspects of paediatric eye disorders like refractive error, childhood cataract, glaucoma, amblyopia, squint, retinal disorders, congenital anomalies, but also adult patients with squint/ double vision problems.

• Squint Correction
• Paralytic
• Concomitant
• Ptosis Correction
• Paediatric Cataract Surgery
• Amblyopia Management

Every child should undergo a comprehensive eye examination at least before they get enrolled in a school. There are conditions such as amblyopia which can be corrected completely if treated timely in early age. Hence periodic eye check-up is advisable.

Amblyopia or Lazy eye is a condition with underdeveloped vision in one or both the eyes during infancy. Children under the age of 8 are at much higher risk of developing amblyopia, as in this time period vision develops. It can be treated if detected in early age group by various modalities such as glasses, patching, eye exercises or surgery depending on the cause.

Cataract is a condition where the natural transparent lens of the eye becomes cloudy or opaque which affects the clarity of vision. It is a widely prevalent myth that cataract only occurs in old age. The reality is that it could even affect a new-born baby and the condition is then called as pediatric cataract.
The surgical treatment involves removal of the cataract and replacing it with an artificial intraocular lens. The treatment does not just stop at surgery, but there may be a need for the child to use glasses for near reading and writing. Regular follow-ups are also advisable.

Strabismus or squint or crossed eyes affects about 3 to 4 % of children in India. Many children manifest strabismus at a very early age. The condition can result from a very simple eye problem to a much-complexed one, such as amblyopia or neurological or brain-related problem.

Treatment of squint varies from person to person, depending on the cause and nature of the condition.
While visiting an ophthalmologist, you may expect a comprehensive eye test followed by measurement of squint using a prism. Some children will require MRI Scan of the brain. The later will only be advised if indicated medically, based upon the clinical presentation of symptoms.
Based on the findings, the most appropriate plan of treatment will be decided by the pediatric ophthalmologist. Squint is usually treated with the use of prescribed glasses, surgery, and the combination of both; glasses as well as surgery and with prism glasses prescribed for double vision.

Neuro-ophthalmology is a field within the eye care that specifically focuses on issues involving the optic nerve and the brain. Up to some extent, It also deals with issues related to the neural control of the eye muscles.

1. Paralysis of the eye muscles and double vision
2. Optic nerve problems
3. Bleeding in the brain that results in the eye or vision-related problems
4. Vision loss related to the lesions in the brain
5. Delayed milestones/visual milestone
6. Behavioural problems in children
7. Unexplained vision loss

P.C.Sharma Eye Hospital conducts once a month visit to Nahan & Paonta Sahib (Himachal Pradesh) and cataract surgeries are being performed there at an affordable cost for the local patients.

Besides this we also conduct once a month free camp at Vill. Azizpur Kalan, Yamunanagar(Haryana).

Ophthalmic plastic surgery is a super-specialized branch of ophthalmology that deals with deformities, and cosmetic concerns of the structures around the eye. It is a highly specialized form of plastic surgery that is so close to the eye that you would want to trust an Oculoplastic surgeon, who is an eye microsurgeon as well as a trained plastic surgeon.

Droopy eyelid (ptosis) can occur as a result of birth defect, injury, muscle disorder, nerve disorder, or simply due to aging. It gives a sleepy appearance, and can even obstruct vision if severe. Ptosis may also cause excessive forehead wrinkling, abnormal head posture such as chin elevation, and eye fatigue. In children below 8 years of age, severe droop might obstruct development of vision leading to a lazy (amblyopic) eye thus reducing vision. In adults, droopy eyelid is mainly a cosmetic concern. Surgery can correct this problem by repairing the muscle that lifts the eyelid. Several surgical options are available, and the type of surgery used depends upon the severity of the droop. After evaluation, your specialist will decide which surgery best suits your need. Health insurance will cover the costs of ptosis surgery, if it was acquired later in life. Any congenital deformity (present since birth) is not covered by insurance.Radiofrequency cautery ensures a bloodless and painful surgical procedure

Eyelid malpositions are abnormal positions of the eyelid, leading to inturning(entropion) or out-turning(ectropion) of the eyelid. This can be present since birth, or secondary to trauma or aging. Eyelid malpositions are common, and often lead to watering, photosensitivity, and even a cosmetic defect. Eyelid malpositions can be corrected with eyelid plastic surgery, and are covered by insurance.

Facial spasm is a condition in which facial muscles function abnormally and are no longer under the direct control of the brain. It can affect the entire face, or just the area around the eyes. Four distinct forms of facial spasm are known: Benign Essential Blepharospasm, Hemifacial spasm, Meige syndrome, and Myokymia. Though the actual problem within the nerve is not fully understood and cannot be cured, its effect on facial muscles can be controlled temporarily by injections of Botulinum toxin, a 10 minute out patient procedure

Humans have two eyes and yet see a single image, this happens because of both eyes coordination. This effortless clear single vision is the outcome of several mechanisms that involve the eye lens focusing, eye muscle movements, integration of all the sensory and motor input signals in the brain and execution of output signal in the eye.
The assessment of the sensory and motor input and output signals requires a comprehensive binocular vision examination. Within this examination there can be sub-specialty like orthoptics, vision therapy etc. Orthoptics is a discipline that assesses if the eyes are straight, predominantly examining the eye muscles.

One of the most neglected areas in ophthalmology, here at P C Sharma eye hospital, patients with end stage diseases are being visually rehabilitated by dispensing special glasses and devices which help patients with minimal to maximize their daily routine activities
Which patients can benefit from low vision devices?

• Advanced diabetic retinopathy
• Advanced glaucoma
• Advanced Age related Macular degeneration
