A cataract is defined as a clouding of lens in the eye where your vision gets blurred. A cataract affects the eyes, when light that passes through the lens prevents a clearly formed image from reaching your retina. The disease is very common and usually, develops as your eyes age or due to any injury caused to the tissues that cover your eye's lens.
Types of cataracts:
- Senile Cataract: This is the commonest of all. It is age-related clouding of the lens. It can affect the near or distance vision and can also cause glare and change in glasses power.
- Secondary Cataract: It can be developed after surgery for other eye problems like glaucoma and other health conditions such as diabetes.
- Traumatic Cataract: It can develop many years later after an injury caused to your eye.
- Congenital Cataract: As the term explains, the disease may be inborn or some children might develop it at a later stage which often affects both eyes.
- Radiation Cataract: It can form after you are exposed to some form of radiation.
A cataract surgery involves the extraction or cleaning of the cloudy lens, which is then replaced by a clear artificial lens.
There are lenses that lies behind our iris and pupil which act much like a camera lens. It helps concentrate light onto the retina at the back of our eye to form a sharply defined image. Besides, the lens also helps our eyes to adjust focus and allows us to see things clearly both far away and up close. The lens is composed of protein and water where the protein is arranged in a manner to keep the lens clear thereby letting light pass through it.
However, as we grow old, some of the protein starts to become thick and cloud a small lens area. This is known as a cataract. With the passage of time, it may inflate and cover more of the lens, making it difficult for us to see.
Besides, there are other causes of cataract such as smoking, addiction of alcohol, prolonged sunlight exposure, to name a few.
When should you opt for a cataract surgery?
Believe it or not, but till date no eye drop or medication has proven to reverse or prevent the formation of a cataract. If a cataract is affecting your nearsightedness or alteration in your prescription, then new prescription eyeglasses may help to better your blurred vision. However, the only treatment for a cataract is the surgical removal of your natural lens. And, most eye doctors recommend this surgery only when the problem becomes severe and starts hampering your day-to-day activities, such as studying or driving at night.

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 is very common and is generally a safe procedure.
How a cataract affects your vision
Cataract surgery is performed to treat cataracts. Cataracts can cause blurry vision and increase the glare from lights. If a cataract makes it difficult for you to carry out your normal activities, your doctor may suggest cataract surgery.
When a cataract interferes with the treatment of another eye problem, cataract surgery may be recommended. For example, doctors may recommend cataract surgery if a cataract makes it difficult for your eye doctor to examine the back of your eye to monitor or treat other eye problems such as age-related macular degeneration or diabetic retinopathy.
In most cases, waiting to have cataract surgery won't harm your eye, so you have time to consider your options. If your vision is still quite good, you may not need cataract surgery for many years, if ever.
When considering cataract surgery, keep these questions in mind:
- Can you see to safely do your job and to drive?
- Do you have problems reading or watching television?
- Is it difficult to cook, shop, do hardwork, climb stairs or take medications?
- Do vision problems affect your level of independence?
- Do bright lights make it more difficult to see?
Complications after cataract surgery are uncommon, and most can be treated successfully.
Cataract surgery risks include:
- Drooping eyelid
- Dislocation of artificial lens
- Retinal detachment
- Secondary cataract
Loss of vision
Your risk of complications is greater if you have another eye disease or a serious medical condition. Occasionally, cataract surgery fails to improve vision because of underlying eye damage from other conditions, such as glaucoma or macular degeneration. If possible, it may be beneficial to evaluate and treat other eye problems before making the decision to have cataract surgery.
Glaucoma: An Overview
This disease can be developed or inherited; it usually refers to the accumulation of fluid inside a person's eyes leading to excessive pressure on his or her optic nerve.
How to Diagnose the Symptoms of Glaucoma:
- A Fundamental Eye Examination: An experienced eye doctor will check the dilated pupils of your eyes so as to take a closer look at the optic nerve that further discerns the stage of glaucoma a patient is in. Doctors tend to keep track on the sequential progression of glaucoma and its specific mode of treatment through pictures of the optic nerve taken during an examination.
- Tonometry may also be performed: Signs of Glaucoma may be spotted through the procedure called tonometry where the doctor will test a person's eye pressure and so on so forth. A visual field test might also be conducted to check if the patient can see things at the periphery of his line of vision.
Symptoms that will help a doctor identify this condition in people:
- A loss of peripheral vision is experienced in the early stages of glaucoma.
- A person may see halos when in the presence of bright lights.
- Your eyes could turn red.
- Hazy or blurry vision is a problem faced by young children affected with glaucoma.
- Glaucoma could be accompanied by headaches and eye pain.
- An affected person might repeatedly feel nauseous.
Ways to Treat Glaucoma:
- Microsurgery can effectively treat Glaucoma: Microsurgery can be performed in various ways. There is one way in which a channel is made to pump out the fluid creating extra pressure on the optic nerve. This method is referred to as trabeculectomy.
- Eye Drops: Eye drops can relieve you from painful glaucoma. They are known to control the formation of excess fluid in a person's eye. In some cases, they can induce the accumulating fluid to flow out of the patient's eyes.
- Laser Treatment: Laser surgeries can be undertaken to get rid of glaucoma. Laser can help in moving out fluid from the eyes of the affected person. It successfully hinders fluid blockage as well. There are different kinds of laser treatments available to cure glaucoma.
Eye flashes or photopsia can be caused by many conditions. Although flashes are harmless, they might indicate some serious eye issue which needs to be addressed immediately. Medical attention should be taken when flashes cause loss of vision and also small spots seem to float from one side to the other, thereby hindering the vision.
Migraines and very severe recurrent form of headaches which last for few hours to many days can cause visual symptoms. The light flashes look like zigzag lines, geometric patterns and sparkles when they occur with a migraine. Flashes might affect one eye or both and occur in the peripheral area of the vision. Light flashes sometime also occur due to ophthalmic migraine, a migraine without a headache.
Posterior Vitreous Detachment
The jelly like substance or the vitreous fluid fill the center of the eye and also gives it shape, is attached to the retina. With age and over time there is shrinking of the vitreous and it begins to detach from the retina. This is known as posterior vitreous detachment. In this the vitreous tugs or pulls on the retina, while the retina gets detached and stimulates it thus causing flashes to occur.
There is no known treatment for posterior vitreous detachment, through regular monitoring of the eye through eye checkups are helpful. Symptoms of this are similar to those of retinal detachment (condition in which there is permanent vision loss).
Retinal Detachment or Tear
Retinal tear and detachment also cause light flashes in the eye. This needs to be treated promptly. In case of permanent vision loss there is detachment of retina at the back of the eye, especially if the detachment takes place over the macula which is the main focus of the vision on retina. When the retina detaches from the eye, it loses the main source of nutrients. As there are photosensitive cells in the retina which are responsible for vision, the results of retina tear are severe.
Retinal damage occurs after trauma or as a complication from diabetes or posterior vitreous detachment. Vitreous gel tends to seep under the retina from the small crevices and holes formed by the retinal thinning. This in turn raises the sections and disconnects it from the eye. This can be corrected by laser treatment, cryopexy or an eye surgery.
A trauma like a hard blow on the head can lead the person to experience flashes of light. Also some medications can lead to toxic levels, like Digitalis can cause flashes of light. The symptoms of eye flashes also occur with macular degeneration, which is an age-related disease and in this the vision reduces gradually.
