The eye is one of the used sense among the other five-senses. The senses of sight is the primary means of gathering visual information around us.
Cataract Surgery
The thinner the cornea the higher risk of developing glaucoma. The thinner corneas are also associated with an increased
severity of visual field loss and a more rapid progression of the disease

What is Glaucoma and Cornea ?
In a healthy eye, the fluid leaves through the drainage canals located between your iris and cornea. With glaucoma, the resistance increases in your drainage canals. The fluid has nowhere to go, so it builds up in your eye. This excess fluid puts on your eye.
What is cause of Glaucoma and Cornea ?
Ocular hypertension (increased pressure within the eye) is the most important risk factor for glaucoma, but only about 50% of people with primary open-angle glaucoma actually have elevated ocular pressure.[16] Ocular hypertension—an intraocular pressure above the traditional threshold of 21 mmHg (2.8 kPa) or even above 24 mmHg (3.2 kPa)—is not necessarily a pathological condition, but it increases the risk of developing glaucoma. One study found a conversion rate of 18% within five years, meaning fewer than one in five people with elevated intraocular pressure will develop glaucomatous visual field loss over that period of time.[17] It is a matter of debate whether every person with an elevated intraocular pressure should receive glaucoma therapy; currently, most ophthalmologists favor treatment of those with additional risk factors.[18]
Open-angle glaucoma accounts for 90% of glaucoma cases in the United States. Closed-angle glaucoma accounts for fewer than 10% of glaucoma cases in the United States, but as many as half of glaucoma cases in other nations (particularly East Asian countries).

What are the symptoms of cataracts ?
You might not have any symptoms at first, when cataracts are mild. But as they grow, cataracts can cause changes in your vision. For example, you may notice that:
- Your vision is cloudy or blurry
- Colors look faded
- You can’t see well at night
- Lamps, sunlight, or headlights seem too bright
- You see a halo around lights
- You see double (this sometimes goes away as the cataract gets bigger)
- You have to change the prescription for your glasses or contact lenses often
Talk with your eye doctor if you have any of these symptoms — they could also be signs of other eye problems.
