Eye Diseases

Cataract surgery: is a procedure to remove the lens of your eye and, in most cases, replace it with an artificial lens. Normally, the lens of your eye is clear. A cataract causes the lens to become cloudy, which eventually affects your vision.

Cataract surgery is performed by an eye doctor (ophthalmologist) on an outpatient basis, which means you don't have to stay in the hospital after the surgery. Cataract surgery can be done traditionally using ultrasound energy to remove the cloudy lens or it can be removed with laser-assisted technology. Cataract surgery is very common and is generally a safe procedure.

Cornea transplant (keratoplasty): 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.

Most cornea transplant procedures are successful. But cornea transplant carries a small risk of complications, such as rejection of the donor cornea.



LASEK (laser assisted epithelial keratomileusis): is a type of laser eye surgery, often used as an alternative treatment for those who are not suitable for LASIK eye surgery. This treatment involves the fine surface layer of the cornea being loosened and folded back, instead of a flap being created and removed, as is the case with LASIK treatment. An Excimer laser is then used to reshape the surface of the cornea, thus correcting the eye’s refractive error.

LASIK is the preferred laser eye treatment by most, as visual recovery with LASEK can be slower, and bandage lenses need to be worn for up to a week. The eye can also be uncomfortable for a few days after treatment. However, not everyone is suitable for LASIK, for instance if your corneas are too thin or flat for LASIK treatment, and, therefore, LASEK eye surgery may be able to offer a great alternative.

LASIK eye surgery can be an alternative to glasses or contact lenses done for the correction of certain common vision problems.

LASIK (laser-assisted in situ keratomileusis): is a type of laser refractive surgery — the best known and most commonly performed. In general, a special type of cutting laser is used to precisely change the shape of your cornea — the dome-shaped transparent tissue at the front of your eye — to improve vision.

Normally, images are clearly focused on the retina in the back of your eye because the light rays are bent properly to contact the retinal surface. With nearsightedness (myopia), farsightedness (hyperopia) or astigmatism, the light is bent incorrectly and it ends up being focused elsewhere, resulting in blurred vision. Traditionally, the blurred vision is corrected by bending (refracting) light rays with glasses or contact lenses. But reshaping the cornea itself also will provide the necessary refraction.
