10 Frequently Asked Questions on Myopia

LASIK Eye Surgery in Kolkata

Myopia is the condition where the distant objects appear blurry and out of focus. This is caused when the eyes are longer than usual. As a result, the distance between the cornea and your retina is greater than in normal eyes. LASIK eye surgery can rectify myopia.

Here are a few frequently asked questions on Myopia:

1. What causes Myopia?

Nearsightedness or Myopia is caused when the shape of your eyeball is more than normal eyeballs. However, in some cases, myopia is also caused by a change in the cornea or the lens. Due to these problems, the light rays entering the eye focus in front of the retina instead focusing directly on it.

2. What are the symptoms of Myopia?

The initial symptom of Myopia is blurred vision. When you look at distant objects, it will appear blurred. You will find yourself squinting and frowning while looking at distant images and objects. You will get frequent headaches, and you won’t be able to read books or newspaper properly without holding it too close to your eyes.

3. When do we develop Myopia?

Usually, nearsightedness begins in your childhood, between the ages of 6 to 12. While you are in your teenage, your eyeballs grow quickly. At that time either it will grow quickly or get worse quickly. By the time you reach 20 years, myopia stops getting worse. Most of the time, the condition stabilises at mild or moderate levels.

4. What are the treatment options for myopia?

Usually, the eye specialist prescribes glasses and corrective lenses for correcting myopic vision. These lenses and glasses help in focusing the images directly onto your retina so that you can see properly. However, these glasses and lenses do not cure the condition. You need to wear them for doing certain activities such as driving a car or reading distant boards or for viewing things located far away.

Apart from these, the doctors may also suggest surgical procedures for vision correction. The most common process for treating myopia is Laser in-Situ Keratomileusis or LASIK eye surgery. Another process used for treating Myopic vision is PRK or Photorefractive Keratectomy.

5. What is LASIK eye surgery?

LASIK eye surgery is commonly used for correcting vision related problems such as Myopia, Hyperopia, and Astigmatism. In this procedure, the cornea of your eye is reshaped so that that light that is entering the eye focuses directly on the retina and you get a clear vision. This is a painless procedure and takes only 15 minutes to complete. The eye surgeon will cut a circular flap on your cornea and then removes some of the corneal tissue using an excimer laser. For myopic vision, the surgeon flattens the cornea, and for farsightedness, the surgeon makes it steeper. There are many places in Kolkata where LASIK eye surgery is performed.

6. What is Photorefractive Keratectomy and how it helps?

Like LASIK eye surgery, PRK (photorefractive keratectomy) too works by reshaping the cornea using an excimer laser. The only difference between LASIK and PRK is the initial steps of the procedure. In LASIK, the surgeon cuts a thin flap in the cornea using a microkeratome or a femtosecond laser. In PRK, the eye surgeon cuts the outer layer of the cornea and discards is before reshaping the corneal tissue using excimer laser. The top layer grows back in a few days after the surgery. And that is why recovery of PRK takes longer than LASIK.

Another variation of PRK called LASEK is also performed. In this procedure, the surgeon lifts the outer epithelial layer and preserves it. At the end of the surgery, the layer is them put back on the eye surface.

7. Can we prevent Myopia?

The development of myopia depends on your genes and your environment. There is no way that you can prevent Myopia. However, you can definitely prevent it from worsening. Use glasses and contact lenses prescribed by the doctor. Remember that, glasses and contact lenses won’t cure the condition, but they will help you enjoy better vision.

8. How is myopia diagnosed?

The doctor will perform a thorough eye check-up for diagnosing myopia. The eye examination may begin with a visual acuity test. In this test, the eye doctor may use a standardised chart of letters of varied size. You will be asked to cover one eye and read that chart aloud. If the test results show that you have myopia, then the doctor will use a retinoscope to examine your eyes. Using that retinoscope, the doctor will throw light into your eyes and evaluate the reflection off the retina. This is used for determining the degree of refractive error in your eyes.

9. What is Degenerative Myopia?

Also known as pathological or malignant myopia, this condition is very rare. This is mostly inherited, and symptoms begin to appear in early childhood. In this condition, your eyeball elongates rapidly, thus causing severe myopia. The condition gets worse usually by teenage or youth. This condition may even get worse during your adult years. People with this condition are highly susceptible to retinal detachment and other conditions such as glaucoma and choroid neovascularization (an abnormal growth of blood vessel).

10. What is High Myopia?

This is a severe form of myopia. In this condition, your eyeball keeps growing and elongates from front to back. This increases your risk for retinal detachment and an early development of other eye conditions such as glaucoma and cataracts.

FAQs for Diabetic Patients

Diabetes is a condition where the blood glucose levels are too high. This is mainly because either your body isn’t producing enough insulin or your body cells aren’t responding to the insulin. Diabetes affects multiple organs of your body, including your eyes. A study by the World Health Organisation says that all patients with Type 1 diabetes develop Diabetic Retinopathy; while 77% of people with Type 2 Diabetes who are living with Diabetes for over 20 years develop this eye condition. The report by WHO further mentions that Diabetic Retinopathy is responsible for 4.8% of the total 37 million cases of blindness all over the world.

Apart from Diabetic Retinopathy, Diabetes also contributes to the development of a number of eye conditions.

Here are a few Frequently Asked Questions on Diabetes

How Diabetes affect the eyes?

Diabetes causes:

1. Blurry Vision

If you have diabetes, you may often find that your vision has become blurry. This is because the high blood glucose levels make your lens swell, thus affecting your vision. For normalising your vision, you need to get your blood sugar levels down. It might take maximum three long months before your get back your normal vision.

2. Glaucoma

If you have diabetes, then you might get a rare form of glaucoma known as Neovascular Glaucoma. This is a condition where new blood vessels grow in your iris, blocking the flow of fluid and raising your eye pressure. Moreover, people having Type 2 diabetes are most likely to have Open-Angle Glaucoma. Medications help in treating Open-Angle Glaucoma. This helps in reducing the eye pressure and facilitates the drainage of fluid. On the other hand, Neovascular Glaucoma is a bit complicated condition and might require surgery. There are many options for glaucoma treatment in Kolkata. If you have diabetes, then it’s a must to get your eyes checked thoroughly in a good eye hospital in Kolkata. It’s because it’s impossible to diagnose glaucoma without thorough eye check-up.

3. Diabetic Retinopathy

The high blood sugar levels can cause severe damage to the blood vessels in your retina causing Diabetic Retinopathy. Controlling your blood sugar levels, cholesterol, and blood pressure is essential for preventing this condition. You may develop Background Retinopathy (your blood vessels are damaged, but it doesn’t affect your vision); Maculopathy (a damaged macula), and Proliferative Retinopathy, a condition where the cells in the back of your eyes do not get enough oxygen and new blood vessels start growing. These blood vessels often bleed, thus scarring the retina.

What are Type 1 and Type 2 Diabetes?

Type 1 Diabetes is when the body doesn’t produce insulin because the insulin producing pancreatic cells are damaged by the body’s immune system. Type 2 Diabetes is the most common form of diabetes. This is caused when either the pancreas isn’t producing enough insulin or the body couldn’t use the available insulin. This condition is common in people who are obese.

What is Prediabetes?

Prediabetes is the condition when the blood glucose levels are higher than normal, but it isn’t high enough to be diagnosed with diabetes. People who have prediabetes are likely to suffer from cardiovascular diseases. Early screening is essential for avoiding any further risks.

What is Gestational Diabetes?

This is a type of diabetes that women usually develop during pregnancy. This is a temporary type of diabetes. If you develop this type of diabetes in one pregnancy, you are likely to develop this during your other pregnancies. Gestational diabetes increases the risk of developing Type 2 diabetes in future. So, timely screening is important.

Who can develop Type 2 Diabetes?

These factors can increase your risk of developing this condition:

  • Family history: The family history of type 2 diabetes increases your risk of getting diabetes increases.
  • Age: with age, your risk of developing type 2 diabetes increases. This may be due to decreased physical activity and loss of muscle mass
  • Obesity: Obesity increases your risk factor for type 2 diabetes. With more fatty tissues, your cells become more resistant to insulin.
  • Inadequate physical activity: if you are less active then you are more likely to develop type 2 diabetes.
  • Unhealthy diet: a diet rich in saturated fats, sugar, and calories increase your body weight thus increasing your risk of getting type 2 diabetes.
  • What are the complications caused by Diabetes?
  • High blood glucose levels can damage your kidneys, eyes, nerves, and cause cardiovascular disease. You become susceptible to foot infection (that may lead to gangrene), stroke, heart attack, and sexual dysfunction.

Why it’s important to take special care of the feet?

People with diabetes are prone to foot problems. The blood circulation in your feet becomes poor thus damaging the nerves and reducing sensation. Check for various foot conditions such as cracked skin, swelling, ingrown toenail, blisters, bleeding corns. Proper foot care ensures that no wounds become so severe that the leg needs amputation.

Do Diabetic people need special diet?

Not really. Just ensure that the diet you are following is healthy and contains complex carbohydrates (whole grain cereals), is low in fats, and includes plenty of vegetables. If you plan your diet accordingly, you can still eat all kind of food and stay healthy.

What is Hypoglycaemia?

Hypoglycaemia or low blood sugar level is the most common complication faced by diabetic people. Due to several conditions such as not eating properly or eating too late, doing vigorous physical activity may drop your blood sugar levels below normal range. Patients usually feel weakness, sweating, and giddiness. At that time, the patient must be given fruit juice or some sugary drink. In case the patient is unconscious, he or she must be given intravenous glucose. Adjusting the dosage of antidiabetic medicine can help avoid this condition.
