We can take good vision for granted – until something goes wrong. Your eyesight is just like your body – you will experience changes as you age. The vision you are born with is not the same vision you have at 16, 35, or 50.
While there are many very successful and effective techniques for treating vision problems, prompt detection and early treatment are the best assurances for healthy eyes. The following are things you can do to help solve vision problems before they become critical:
- Schedule regular check-ups with an ophthalmologist
- Educate yourself on what can go wrong with your eyes
- Take sensible precautions to protect and preserve your sight, such as wearing sunglasses for UV protection and protective goggles in appropriate environments
- Take proper maintenance of your contacts

A cornea transplant is a surgical procedure to replace part of your cornea with corneal tissue from a donor. Your cornea is the transparent, dome-shaped surface of your eye that accounts for a large part of your eye’s focusing power.
A cornea transplant can restore vision, reduce pain and improve the appearance of a damaged or diseased cornea. A cornea transplant, also called keratoplasty, is typically performed as an outpatient procedure.
Most cornea transplant procedures are successful. But a cornea transplant carries a small risk of complications, such as rejection of the donor cornea.
A cornea transplant is most often used to restore vision to a person who has a damaged cornea. A cornea transplant may also relieve pain or other signs and symptoms associated with diseases of the cornea.
A number of conditions can be treated with a cornea transplant, including:
- A cornea that bulges outward (keratoconus)
- Thinning of the cornea
- Cornea scarring, caused by infection or injury
- Clouding of the cornea
- Swelling of the cornea
- Corneal ulcers, including those caused by infection
- Complications caused by previous eye surgery
Cornea transplant is a relatively safe procedure. Still, a cornea transplant does carry a small risk of serious complications, such as:
- Eye infection
- Increased risk of clouding of the eye’s lens (cataracts)
- Pressure increase within the eyeball (glaucoma)
- Problems with the stitches used to secure the donor cornea
- Rejection of the donor cornea
- Swelling of the cornea
Signs and symptoms of cornea rejection
In some cases, your body’s immune system may mistakenly attack the donor cornea. This is called rejection, which may require treatment or another cornea transplant.
Make an appointment with your eye doctor if you notice any signs and symptoms of rejection, such as:
- Loss of vision
- Sensitivity to light
Rejection occurs in about 20 percent of cornea transplants. Put another way, for every 10 people receiving cornea transplants, two people can expect to experience rejection of the donor cornea.
Limbal Relaxing Incision (LRI)
C Limbal relaxing incisions (LRI) are a modification in the shape of your cornea used to treat astigmatism. Astigmatism is present when the cornea is not perfectly round; resulting in one portion of your eye does not see the same as the other portions. A cornea with astigmatism is shaped more like a football rather than a basketball. LRI’s are incisions that are placed on the far outer edge of the cornea (the limbus) resulting in a cornea that is more round resulting in your uncorrected vision being improved.
There is usually little or no, post-operative discomfort. The procedure is very safe and is not associated with glare or starburst. The cornea is usually stable within a week, which means your vision should be stable.
LRI procedures have gained widespread acceptance among cataract surgeons in recent years. The benefits of LRI procedures include almost immediate recovery of vision and excellent quality of vision after LRI. LRIs are often combined with a cataract operation to reduce preexisting astigmatism and thus, resulting in better postoperative uncorrected vision. When using the Premium IOL implants in patients with over one diaptor of astigmatism, LRI might be required to reduce the pre-op astigmatism, thereby increasing the patient’s overall satisfaction.
Optical Coherence Tomography (OCT)
Optical Coherence Tomography (OCT) is an innovative scanning system that produces highly detailed images of the retina, the innermost layer of the interior of the eye. This instrument can “see” below the surface of the retina to examine the retinal layers. These pictures allow our ophthalmologists to identify and treat problems in the best possible way.
With the OCT, we can detect glaucoma and other abnormalities of the retina, including age-related macular degeneration (AMD), detached retina, macular holes, diabetic macular edema and more. The OCT never touches the eye, so there is no discomfort and requires only minutes to scan the eye.
Selective Laser Trabeculoplasty (SLT)
SLT is the newest type of laser treatment for open-angle glaucoma. The SLT uses a combination of frequencies that allow the laser to work at very low levels that allow the procedure to be safely repeated many times. The SLT treats specific cells and leaves the mesh-like drainage canals surrounding the iris intact. The objective of the surgery is to help fluids drain out of the eye, reducing intra-ocular pressure that can cause damage to the optic nerve and loss of vision.
