Cornea Transplant Surgery

An eye is considered to be one of the most important part of the human body. Eyes are organs that perceive light and forms a communication with the brain providing all the necessary data. The brain then processes the raw data and acts accordingly. An eye is a complex component of the human body comprising of various and sensitive minute parts. A transparent front part of the eye that acts a protection shield for the iris and pupil is cornea. Sensitivity, transparency and presence of immune cells make cornea a very special tissue. Cornea transplant surgery is an operational method in which a damaged cornea is replaced by donated corneal tissue. It is very much admissible to consult a trained cornea surgeon in India and expert for successful cornea transplant surgeries.

Corneal Transplantation

Corneal transplantation surgery, a process in which damaged corneal tissues are replaced, is also referred to as corneal transplant. It is one of the most successful organ transplantation surgeries in the world. Replacement of cornea can restore completely or partially lost vision, reduce pain and improve the efficiency of cornea. Also known as keratoplasty, the transplantation surgery is considered as successful sight saving operation for improves the optical quality of cornea. Some of the conditions that might require cornea transplantation include malfunctioning of cornea’s inner layers, keratoconus (bulging or change in shape of cornea), swelling in cornea and tissue growth in cornea. Occasionally corneal transplantation surgery is combined with various refractive surgeries, cataract surgeries and many such surgeries. Owing to technological developments and medical advancements, the number of corneal transplantation surgeries in India has increased subsequently providing sustained protection from cornea diseases.

Donor Corneal Tissue

Corneal transplantation includes replacement of damaged or diseased cornea by donor corneal tissue. A thorough evaluation of donor cornea is essential for the success of corneal transplantation surgery. Due to latest inventions in the field of medical science, today a single donor cornea is divided into 3 parts and is used in different patients for improving visual acuity. Detailed screening of human donor cornea during transplantation of cornea ensures successful transplantation surgery. However there are many risks involved in the surgery. These risks are relatively very small but they can cause hazardous effects if the surgery is not done under proper care. Some complications that could occur are bleeding, eye infection, increased sensitivity to light, rejection of new cornea, increased redness of the eye and many such dangerous complications. Hence it is always advisable to consult a cornea disease treatment specialist for successful treatment of cornea disorders.

Keratoconus
Which part of your body lets you see this beautiful world? Which part of the body lets you cry when you are down? Which part of the body helps you to focus on near or far objects? If you guessed the eye, you are right. In human context eyes are both windows and beacons for the mind. It is considered as the most special organ of the human body. Cornea, retina, iris and pupil are the most important parts of the eye. Owing to various effects, many a times a defect occurs within these organs which affects the proper functioning and efficiency of the eye. These defects are classified as '''corneal disorders. Keratoconus''' is one such corneal disorder in which the cornea is cone shaped and the surface is irregular as a result of which the image projected onto the brain is a distorted image. It is a degenerative eye disorder that weakens the cornea and affects its normal functioning. Most often the bulging occurs in the lower part of cornea that affects the evenly bending pf the light.

Causes and Risk Factors

The cause of Keratoconus disorder is still unknown. However, recent studies show that Keratoconus disease results from an inherited corneal abnormality (hence called a generative disorder). Other reasons that could result into this deadly disorder are: an injury to the eye, eye disorders including retinitis, pigmentosa, Noonan syndrome, Down's syndrome and many such diseases. Vigorous eye rubbing can also affect the shape of cornea leading to Keratoconus.

Symptoms

First symptom of Keratoconus could be itching or allergies. Itching causes patients to rub their eyes more forcefully resulting into Keratoconus eye disease. Photophobia and haloes are also typical symptom of Keratoconus. Other symptoms of Keratoconus include gradual loss of eye sight, astigmatism and blurred eye sight with illness. These symptoms may be unilateral initially and become bilateral in later stages. Reporting of multiple images, ghosting of images and monocular diplopia are also symptoms of Keratoconus.

Diagnosis

Corneal collagen cross linking with riboflavin is the latest innovative method especially for Keratoconus patients for regaining the proper shape of cornea. Also known as C3R treatment, the method includes application of riboflavin solution to the eye which is then activated by illumination of ultraviolet rays. Corneal collagen cross linking is then induced by exposure of eyes to safe and effective rays. The method reduces progression of Keratoconus, increases the strength of cornea and improves cornea’s optical properties. Early use of C3R with riboflavin is advised for hault of any further progression of Keratoconus once it is identified.

Benefits of Corneal collagen cross linking


 * The solution used in C3R improves the strength of the cornea over a period of time with less evasive procedures. The method is relatively comfortable as the epithelium layer is only disrupted rather than removed.


 * Improves the corneal symmetry and visual acuity of the eye.


 * Helps to reduce the conical shape of cornea that occurs due to keratoconus disease.
 * Collagen cross linking method stabilizes progressive ectasia. However it is not the complete cure of the disease.

It is very essential to seek medical prescription only under the guidance of trained cornea surgeon, for treatment of Keratoconus. There are number of eye banks in India, but you must only choose the best eye bank for successful treatment of cornea.

Intracorneal Rings for Keratoconus Correction
Keratoconus is an eye disorder that causes distortion and reduced vision affecting the cornea. It is categorized as progressive, non inflammatory and bilateral corneal disorder characterized by weakening of corneal surface distortion. The cone shaped bulging of cornea deflects light as it enters on the eye causing distorted vision. As the scale of distortion increases, it causes progressive nearsightedness and astigmatism resulting into blurred vision. Recent studies have revealed that keratoconus disease may be due to imbalance of enzymes within the cornea. The imbalance makes the cornea more damage prone organ. Eye hospital in Mumbai offers treatment of keratoconus through intrastromal corneal implants or intrastromal corneal rings.

Intracorneal Rings

Intracorneal rings are thin rings that are inserted in the peripheral area of the cornea for correction of blurred vision and many a times for diagnosis of Keratoconus. Vision correction using corneal rings requires experienced ophthalmologists even though the process requires small incision in the cornea of the eye. Intrastromal corneal ring segments are made of PMMA, an acrylic glass commonly known as Perspex. Intracorneal rings can be removed at anytime and they can also be replaced at anytime. They are designed for long term colour vision. The concept of intra corneal rings appears promising for correction of blurred vision and low myopia. ICR is one of the best solutions available for cornea disease treatment. The embedding of the rings in cornea changes the refraction of light passing through the cornea. They remain motionless and invisible to the naked eye because they are as transparent as the corneal tissue. By using intracorneal rings, the patient can avoid the risk involved in transplantation and prevent continuous thinning of cornea.

Advantages of Intracorneal Rings
 * The procedure of insertion of intracorneal rings is a rapid method that lasts few minutes.
 * The method possesses very high success rate.
 * The recovery rate is also very high. Patients are discharged in very short time post operation.
 * It is completely reversible procedure meaning if by any means there is a need to remove the rings, the patient’s vision will revert to how it was initially. Rings are completely transparent.


 * They are particularly adjustable and can be exchanged for rings of various thicknesses.
 * Intracorneal rings for keratoconus correction can also correct high myopia.
