Corneal Transplants What Are They

Penetrating Keratoplasty (PK)
This type of cornea transplant replaces the full thickness of the cornea with a healthy and clear donor tissue and is required when a cornea has been severely damaged or disease, and where no other option of surgery remains. PK can be carried out under local or general anaesthetic and takes about one to two hours to complete. During surgery, a central 8mm button of cornea is removed and a similar sized button of the donor cornea is stitched in with tiny stitches. After surgery vision will stay misty and/or cloudy for a few days and will improve gradually for about 12-18 months. Individual stitches may be removed from three months after the surgery, but complete stitch removal is not performed until at least one year after the surgery. Following surgery, and once fully healed, around 75% of transplant recipients have adequate vision to drive legally, but to get the best results from vision, glasses or contact lenses may need to be worn.

Deep Anterior Lamellar Keratoplasty (DALK)
This type of cornea transplant is a partial thickness transplant and replaces the front 99% of the cornea with a donor cornea. Unlike penetrating keratoplasty, DALK keeps the back layers of the cornea, the Descemet’s membrane and endothelium layer, in place and it is used as an alternative to PK, when these back layers of the cornea are healthy. The surgery itself is carried out much the same as PK, but just less donor cornea is used. Again, stiches are used to keep the donor tissue in place, but as only part of the cornea has been replaced, healing and visual recovery are usually quicker than what are seen with PK. To get the best vision following surgery, glasses or contact lenses may need to be worn.

Endothelial Keratoplasty (EK)
This type of cornea transplant is a partial thickness transplant and replaces only the back layers of the cornea. Unlike to above two transplants, EK can be further split into two methods; Descemet’s stripping endothelial keratoplasty (DSEK) and Descemet’s membrane endothelial Keratoplasty (DMEK). Both DSEK and DMEK are very similar and the procedure to carry them out is the same, but DMEK differs as the donor cornea tissue does not include any stromal layer tissue. The consultant ophthalmic surgeon will decide which surgery is necessary, depending on the damage or disease that is present. EK transplants are used when there is a problem at the back of the cornea. To help keep the cornea clear, the cells lining the inside of the cornea pump fluid to stop the cornea from swelling, if there are not enough cells, due to disease or damage, then the cornea starts to swell and vision will become cloudy. The surgery is carried out differently when compared to PK and DALK; it will again be under either local or general anaesthetic but a very small incision is made between the coloured and white part of the eye. The eye surgeon removes the dysfunctional endothelial cells through this opening and a disc of donor cells is placed back inside the eye. The donor endothelial cells are pressed to the back of the cornea with an air bubble and the patient will need to lie still for about 1 hour following surgery to make sure the air bubble stays in place. Occasionally, a few stitches to close the incision may be needed. Vision will stay misty or cloudy for a few days, and will get better over 3-4 months, as with all types of corneal transplants glasses or contact lenses may be needed after surgery to get the best results from vision

Transform How You See The World With Lasik Laser Treatment

Eyes are the God’s most precious gift to mankind. Eyes are the mirror of our body and mind. And this makes very essential for us to keep our eyes healthy throughout the life. Today, farsightedness or nearsightedness can be treated with LASIK laser treatment.

LASIK is an outpatient refractive surgery procedure. A laser is used to reshape the cornea (the clear, round dome at the front of the eye) to improve the way the eye focuses light rays onto the retina at the back of the eye. With LASIK, an ophthalmologist creates a thin flap in the cornea using either a blade or a laser. The surgeon folds back the flap, and accurately remove a very specific amount of corneal tissue under the flap using an excimer laser. The flap is then laid back into its original position where it heals in place.

Specs removal operation for people whose eye sight is weak helps them get free from eye-glasses. For people who are nearsighted, LASIK is used to flatten a cornea that is too steep. Farsighted people will have LASIK to achieve a steeper cornea. LASIK can also correct astigmatism by shaping an irregular cornea into a more normal shape.

The leading eye care provider, Centre for Sight, is known for achieving excellence in eye care by providing specialized eye care, honest clinical opinion and latest technology. Eye care, to be truly effective, is all about harnessing state-of-the-art technology to be operated by the deft hands of experts.

Taking care of eyes in old age becomes all the more difficult. Most of the people after age 50 are likely to hear from their eye doctor, “You have cataracts.” A cataract is a clouding of the lens inside the eye, causing vision loss that cannot be corrected with glasses, contact lenses or corneal refractive surgery like LASIK. In cataract, there is a buildup of protein in the lens of the eye which makes it cloudy. This prevents light from passing clearly through the lens, thereby causing loss of vision.

Advancing age is a primary reason for cataract. With age, protein of the lens turns opaque. Other causes of cataract are metabolic disorders such as diabetes, excessive exposure to sunlight, lifestyle disorders like heavy alcohol consumption and smoking. Injury to the eye can also lead to clouding of the lens of the eye. When cataract forms, surgery is the only way to treat it. In cataract surgery, the surgeon removes the clouded lens and puts an Intra Ocular Lens (IOL) in your eye. Your vision will be as good as pre-cataract days, though you may need to wear glasses. Over the years, cataract surgery has moved from vision restorative to refractive surgery, so that you have reduced need of glasses.

A perfect combination of expertise of experienced surgeons and latest technology lead to a successful surgery. Centre for Sight is considered as one of the leading hospitals in India for cataract surgery. The hospitals are fully equipped with trained eye specialists for treatment of the patients

What Is Glaucoma, Symptoms, Diagnosis And Treatment For It

What is Glaucoma?

Glaucoma is a condition that affects the optic nerve in the eye. The optic nerve is majorly responsible for vision and transmits images to the brain. The cause for Glaucoma is an increased pressure inside the eye, also known as intraocular pressure. This force of pressure in the eye leads to the damage of the optic nerve.

Glaucoma can be hereditary in nature and may show up in the later stages of life. Poor blood flow to the optic nerve also causes Glaucoma. Without proper treatment, Glaucoma can cause permanent vision loss.

What are the symptoms for Glaucoma?

If you’re over 40 years of age and have a family history of Glaucoma, it is highly recommended to get a complete eye examination done from a Glaucoma specialist every 1 to 2 years. If diabetes or a history of glaucoma is prevalent in the family, a person may be more prone to eye disorders and diseases and may require frequent eye check-ups.

People who suffer from poor eye vision or are suffering from diabetes are also at the risk of getting Glaucoma. People who have suffered accidental injury or trauma on their eyes or are on steroids are equally at the risk of getting Glaucoma.

Glaucoma is considered to be difficult to be understood by the patient himself and difficult to diagnose as well at an early stage. Other symptoms for Glaucoma include-

Pain in the eyes, severe headaches, blurred vision or the appearance of halos around lights, redness in the eyes, hazy eyes, nausea or vomiting and narrowed vision or tunnel vision are some symptoms which must not be ignored.

Address all your eye problems carefully with a Glaucoma specialist to ensure a perfect vision.

How common is Glaucoma?

Glaucoma is the second leading cause of permanent blindness in the world today. Studies reveal thatapproximately6 million people suffer from blindness due to this disease.

What is more adverse is that Glaucoma is initially difficult to diagnose. This is because the disease causes no symptoms other than the first sign that is a gradual loss of side vision (which is the peripheral vision) and also it is difficult to understand. Due to its difficult diagnosing, Glaucoma is also known as �sneak thief of vision’.

How is Glaucoma diagnosed?

The Glaucoma specialist to provide you Glaucoma treatment will use eye drops to dilate your pupils and examine them carefully. Scans and pictures are also taken by eye specialists to observe the eye conditions over a period of time. Tests such as Tonometry are conducted to check the eye pressure. Visual field tests and examination help the eye doctor to diagnose Glaucoma.

What is the treatment for Glaucoma?

It must be understood that Glaucoma causes permanent vision loss and this is non-reversible in nature. But, Glaucoma can be controlled and its effects can be regulated by a proper treatment by a Glaucoma specialist.

Here, the intraocular pressure on the optic nerve can be reduced and prevented by eyedrops, medicines, laser or incisional surgery.
