What Is Glaucoma?

Recognizing the Symptoms

Glaucoma is the name given to a group of conditions in which the optic nerve sustains damage where it leaves the eye.
In many cases, this damage is associated with a rise in pressure within the eye. As the pressure builds, it compresses the fragile blood vessels supplying the optic nerve, which sends messages to the brain. If left untreated, this can lead to irreversible damage to the optic nerve.

Cataract Surgery

Reasons for Cataract

A cataract is the clouding of the lens in your eye which causes blurred or hazy vision. Ageing is one of the most common cause for cataracts other reasons may be eye injuries (Trauma), disease and long term medication of some drugs.

How a Normal Eye Works ?

The human eye functions in much the same way as a camera. Light passes through the lens of the camera and is focused on the film. Your eye works in a similar, but more complex manner. Your eye also has a lens. But instead of film, the image forms on the retina, which is at the back of the eye. Normally, the lens is a clear, transparent structure through which light can freely pass and focus on the retina.The retina responds to the image and sends signals to your brain, creating an instant picture, which changes as your view changes.

Retinal Diseases

What is Retinal Diseases ?

The retina is the most important part of your eye! It is a thin film of nerve tissue which lines the inside of your eye. Images of the things you see project onto the retina like pictures on a movie screen. The retina then sends these images to the brain making you aware of what you see.

Common diseases of the retina that cause blindness:

1. Diabetic Retinopathy

2. Retinal Detachment

3. Age related Macular Degeneration

Toric Lens Implant

The Normal Eye :

When the surface of a normal eye's cornea has a spherical curve, like the shape of a basketball, light rays passing through it bend toward its center and focus on one spot.

Astigmatism :

Sometimes, the surface of the cornea is curved more like a football, with both flatter and steeper curves. When the surface of the cornea has an uneven curvature, vision becomes distorted. This common irregularity, called a "Corneal Astigmatism," causes blurred or distorted vision because light rays are not focused at one spot to provide clear vision.
A person who has both Cataract and Corneal Astigmatism will not regain high-quality distance vision after surgery to remove the Cataract unless the Astigmatism is also corrected.

General eye check up

What is routine eye check up?

Eye examinations check for the visual function for proximal vision as well as distance vision. The basic visual acuity screening identifies if and when one will need to start using glasses for the first time.

How can I check my eye health?

1 Place yourself 40 centimeters from the screen. 2 If you have glasses for distance vision or glasses with progressive lenses, keep them on. 3 Without pressing on the eyelid, cover your left/right eye with your hand. 4 Indicate if you see lines that are darker.

Pediatric eye diseases

Common Pediatric Eye Disorders :

1. Blocked tear ducts.
2. Cellulitis of the eye.
3. Crossed eyes.
4. Headaches.
5. Lazy eye.
6. Pink eye.
7. Refractive errors including astigmatism, farsightedness and nearsightedness.
8. Stye


LASIK is a surgical tehnique for the correction of refractive errors (myopia, hyperopia, astygmatism). It results in a reshape of the cornea with ocular surface and especially tear film disease. It is a cause for a iatrogenic dry eye syndrome. Neurogenic and inflamatory theory explain this disease.

What is LASIK surgery?

Laser-assisted in situ keratomileusis (LASIK) can be an alternative to glasses or contact lenses. During LASIK surgery, a special type of cutting laser is used to precisely change the shape of the dome-shaped clear tissue at the front of your eye (cornea) to improve vision.
