Who is an Eye Specialist? Signs that You should Visit One

eye specialist

Eyes indicate a lot about your health including the early signs of many diseases such as diabetes, blood pressure, high cholesterol, and jaundice. By visiting your eye specialist often, you can discover those underlying causes early and take necessary precautions to prevent them. Here we share with useful insights on who is an eye specialist and when should you visit one: 

Who is an eye specialist?

An eye specialist is also known as an ophthalmologist. They perform eye tests, diagnose and treat disease, prescribe medications, and perform eye surgery.  They also prescribe glasses or contact lenses.  Here are some signs that you should visit an eye specialist:

1. Vision problems 

If you are experiencing vision problems such as blurred vision, eye floaters, double vision, halos around bright lights, or struggling to read or see objects at a distance, it can be a sign of an underlying medical condition. There are many eye conditions that may lead to loss of vision if timely treatment is not sought.

2. Eye pain

If you get eye pain that persists for too long, you have to visit your eye doctor. Mostly, eye pain causes due to the reasons such as glaucoma, or injury in the cornea.

3. Infection in the eye

There are many things that lead to allergic reactions in the eyes including dust mites. Sometimes, allergic reactions lead to serious infections. In that case, visit the nearest eye doctor. Eye infection symptoms include eye secretion, itchy red eyes, and blurry vision.

4. Frequent squinting

You may squint your eyes to focus on the blurred objects, things, or images in front of you. Squinting can decrease the image size to get a clear view and reduce the extra light that your eyes receive. But, this temporary fix is not an ideal way of dealing with poor vision. So, frequent squinting is a valid reason that you must get your eyes examined by an eye doctor.

5. Diabetes diagnosis

If diabetes runs in your family, or if you are diagnosed with diabetes, it is essential to get your eyes examined regularly by your eye doctor. Those suffering from diabetes are at a higher risk of developing glaucoma, cataracts, and diabetic retinopathy.

6. Constant headaches

Several eye problems such as inflammation in the optic nerve or glaucoma can trigger headaches. Going for regular eye checkups can prevent major eye complications. Headaches could be related to eye strain.

If you or your family member has been suggested to undergo eye surgery, you are bound to go for a well-experienced and qualified eye surgeon. But how do you choose one? Here we share a few tips to choose a good eye surgeon in Kolkata.

1. Check experience and credentials

It’s important to do your research when choosing an eye surgeon. You want to make sure that they have the experience and credentials necessary to provide quality care. Here are some things to consider:

  • How long has the surgeon been in practice?
  • What is his/her success rate?
  • What is the experience of the eye surgeon with your particular condition?

2. Find out about specialisation 

If you’re looking for an eye surgeon, it’s important to choose someone who is specially trained and experienced in the type of surgery you need. There are different types of eye surgeons, each with their own specialised area of expertise. For example, some surgeons specialise in cataract surgery, while others specialise in glaucoma surgery.

3. Get referrals from family and friends 

Ask family and friends if they know anyone who has had eye surgery. Once you have a few names, you can research online or call their office to enquire more. 

4. Ask your eye doctor 

Choosing an eye surgeon is a big decision. You want to make sure you find someone who is experienced and qualified to perform the procedure you need. The best way to find a qualified surgeon is to ask your eye doctor for a referral.

Your eye doctor knows your medical history and can recommend a surgeon who is familiar with your specific condition. 

 5. Check reviews of patients 

When it comes to choosing an eye surgeon, you want to be sure that you’re making the best possible decision for your health. One of the best ways to do this is to check reviews from patients.

There are a few different places you can look for these reviews. One option is online forums dedicated to discussing eye health. 

6. Your experience after the initial consultation

After your initial consultation with an eye surgeon, you will likely have a good idea of whether or not you would like to move forward with surgery. If you do decide to have surgery, the next step is to schedule a pre-operative appointment. This appointment is important in order to confirm the date and time of your surgery, as well as to go over any final questions or concerns you may have.

7. Well-versed with the latest technology

When you are choosing an eye surgeon, you want to be sure that they are using modern technology. This will help ensure that they can provide you with the best possible care. There are a few things to look for when you are checking out surgeons:

What’s the Best Cataract Treatment?

cataract treatment
Cataracts are a common condition that affects many people as they age. With age, proteins in the lens start to break down, causing the lens of the eyes to become cloudy.
Cataract surgery is an effective way of removing the cloudy lens and replacing it with an artificial lens, which will help in see better. If you are suffering from cataracts and wondering what’s the best cataract treatment, here are some insights that you will help: 

  • When can cataract surgery be done?

If you have a cataract, that doesn’t mean you need surgery. Some people, especially those who are not too old manage well with the condition if they wear prescription glasses or use a magnifying lens or use brighter lighting. However,  your eye doctor may suggest surgery when cataracts cause more severe symptoms such as dim or blurred vision or double. Surgery is usually recommended when cataracts make it too hard to read, work on a computer, drive or do anything else that is needed for clear eyesight.

  • Basics of cataract surgery

During cataract surgery, the natural lens inside your eye is replaced with an artificial lens for restoring clear vision. The surgery is an outpatient procedure. This means it does not require an overnight stay in the hospital.

There are mainly two types of cataract surgeries:

  • Phacoemulsification surgery: Cataract Phacoemulsification surgery is a commonly performed surgical procedure to treat cataracts. This type of surgery involves breaking up the cataract using ultrasound energy and then removing it from the eye. Phacoemulsification surgery is safe and effective, and most people who have the procedure experience significant improvement in their vision.

  • Laser cataract surgery: Laser cataract surgery is a type of surgery that uses a laser to break up and remove the cloudy lens inside your eye. This can help improve vision. The surgeons first make a small incision in the eye. They will then use the laser to break up the cloudy lens and suction it out. A new, clear lens will be put in its place. Laser cataract surgery can be done in just a few minutes. Recovery from laser cataract surgery is usually quick. Most people can see well enough to return to their normal activities within a day or two.

  • Which is better: Phacoemulsification surgery or laser cataract surgery? 

The goal of any cataract surgery is to give the best vision possible. Both types of surgery are safe and widely performed, so it’s important to talk to your eye doctor to determine which type of surgery is best for you.

  • Which has the shorter recovery time? 

The recovery time for both phacoemulsification and laser cataract surgery is the same. Some people may find their vision clear within just a week or two, while few others can see clearly almost immediately. It takes about 3 months to fully recover from cataract surgery.

  • How will the doctor decide whether you are an ideal candidate for surgery? 

There are several factors that will be taken into account in order to decide if cataract surgery is the best option for you. These include:

  • The severity of your cataracts
  • How much they are impacting your daily life and activities
  • Your overall health
  • Your age

60+ Eye Health: How to Maintain Healthy Eyes

eye specialist

Though eye problems can occur at any age, they are more common in later years of life. Eye diseases such as cataracts, age-related macular degeneration (AMD) and glaucoma are more common among the elderly. Medical conditions such as diabetes and high blood pressure increase the risk of age-related eye diseases. If you are above the age of 60, it is important to adopt a healthy lifestyle that promotes good eye health. Here we share with some useful insights for seniors on maintaining good eye health:

1. Include food that benefits your eye: The health of your eyes can be greatly determined by the type of food you eat. A study shows that certain types of diet can help improve your eye health.  Additionally nutrients such as omega-3 fatty acids, lutein, zinc and vitamins C and E can prevent vision problems caused due to old age.

2. Quit smoking: Smoking is not only harmful to your lungs but also to your eyes. It can increase the chances of cataracts and macular degeneration.  Smoking can also affect the optic nerve, which can increase the chances of glaucoma. So if you  smoke, it is best to quit smoking.

3. Keep sugar levels and BP under control: Hypertension and diabetes are not just linked to cardiovascular diseases but they also increase the risk of eye diseases. These conditions lead to adverse changes in the blood vessels of the eyes. If you are suffering from any of these conditions, it is important to keep them under control and regularly see an eye specialist. 

4. Exercise regularly: Exercising regularly is good for the overall health as well as eye health.  Being physically active keeps blood pressure and glucose levels in check. Studies have shown that exercising regularly can improve eye health and  reduce the chances of eye diseases such as cataracts or macular degeneration.

5. Protect your eyes from the harmful UV rays:  Wearing protective sunglasses can greatly reduce the effect of UV rays on the eyes. Protecting your eyes is important because too much UV exposure might lead to the formation of cataracts or increase the chances of macular degeneration.

Note: If you wear prescription glasses, opt for  sunglasses with power lenses.

6. Visit an eye specialist at least once a year : One of the effective ways to keep your eyes healthy after the age of 60 is to visit an eye specialist at least once a year.  If you already have an eye condition, you may have to visit an eye specialist more frequently.  Regular eye check ups can help  detect eye diseases in the early stages. This can increase the chances of better treatment.

FAQs and Their Answers on Dilated Eye Exam

Corneal Transplant in Kolkata

Dilated eye exams are an important part of eye health care. They let your doctor see the back of your eye and check for problems. How frequently you need a dilated eye exam depends on your age and risk factors. Some people may need them every year, while others may only need them every few years. If you are facing eye problems, talk to your eye doctor or visit an eye hospital to understand what’s best for you. In this blog, we will discuss dilated eye exams in detail.

What is a dilated eye exam?

A dilated eye exam is a type of eye exam where the staff administers eye drops to widen the pupil. This lets the doctor get a better view of the back of the eye and check for any signs of damage or disease. Dilated eye exams are generally recommended once a year for adults over the age of 60, as this is the age group most at risk for conditions like glaucoma and macular degeneration. However, people with a family history of eye disease may need to start having dilated exams earlier. The drops used in a dilated exam usually take about 15-20 minutes to take effect, and they can cause blurred vision and light sensitivity. For this reason, it is important to plan ahead when scheduling a dilated exam. Someone should be available to drive you home after the exam, as your vision will not be fully recovered for several hours.

How often do you need to get a dilated eye exam?

Most people need to get a dilated eye exam at least once every two years, although some factors may require more frequent exams. These include diabetes, a family history of glaucoma, or a history of eye problems. Children and teenagers should also have their eyes checked every year or two, even if they don’t have any symptoms of vision problems. During a dilated eye exam, the doctor will administer drops in your eyes to widen the pupils. This allows for a more thorough examination of the retina and optic nerve. The doctor may also use other tests to check for glaucoma or other eye problems. In general, it is best to get a dilated eye exam every two years, but some people may need to take this test more often.

What happens during a dilated eye exam?

The drops take about 15-20 minutes to work, and your vision may be blurry during this time. You may also be more sensitive to light. For these reasons, it’s important to have someone else drive you home after the procedure. The effects of the drops usually last for several hours, so it’s best to plan for a relaxing afternoon after your exam.

How does dilation work?

Dilation is a common procedure used during eye exams. The dilation process usually takes about 15-20 minutes to take effect. Once the pupils are dilated, the doctor will examine the retina and optic nerve for any signs of damage or disease. After the exam, the dilation will gradually wear off, and the pupils will return to their normal size. You may experience blurry vision or increased light sensitivity after dilation, so it is important to have someone drive you home if your eyes are dilated.

Cataracts are a common condition that causes blurry vision. They happen when the eye’s lens becomes cloudy or opaque, making it difficult to see. 

Cataracts usually develop slowly and can eventually lead to blindness if not treated. Surgery is the only way to remove cataracts and restore clear vision. 

Cataracts are most often caused by ageing, but they can also be caused by trauma, certain medications or other health conditions. Anyone can develop cataracts, but they are more common in older adults. 

There is no prevention for cataracts, but surgery can usually correct the problem. The earlier you catch the symptoms, the better your chances of a successful surgery. 

If you think you might have cataracts, make an appointment with your eye doctor or an eye specialist. They will be able to guide you and help you with the right treatment plan.

There is no set stage at which cataracts must be removed. The decision to remove cataracts is typically based on the severity of the symptoms and the impact on a person’s quality of life.

6 FAQs on Eye Floaters and Their Answers

	glaucoma treatment in kolkata

Are you one of the millions of people who experience eye floaters? If so, you may have a lot of questions about them. This blog post will answer six common questions about eye floaters. Keep reading!

1. Why do you get floaters in your eyes?

Floaters are tiny specks or strings that float in your field of vision. They’re usually harmless and don’t require treatment. Floaters are more common as you age, but they can also occur if you have certain eye conditions, such as diabetic retinopathy, glaucoma or uveitis. 

Most of the time, floaters are nothing to worry about. However, if you experience a sudden increase in the number of floaters or see flashes of light, you should see an eye doctor immediately.

2. How do you know if an eye floater is serious?

In some cases, eye floaters can be a sign of a serious underlying condition, such as retinal detachment. If you experience any sudden onset or change in your eye floaters, it’s important to see an ophthalmologist right away and get the right eye treatment. 

In addition to eye floaters, if you’re  experiencing symptoms such as vision loss and flashes of light, you may be suffering from a serious eye condition.

3. Can floaters affect vision?

Floaters are tiny clumps of gel or cells that float in the vitreous, the clear jelly-like substance that fills your eye. Although they may be annoying, floaters usually don’t affect vision. 

In some cases, however, floaters can interfere with vision. In such cases, consult an eye doctor immediately. The best way to treat floaters depends on the cause. If a tear in the retina causes them, surgery may be necessary.

Note:  In most cases, no treatment is necessary. If floaters are caused by debris in the vitreous, they will eventually settle at the bottom of your eye.

4. Can eye floaters go on their own?

When you first notice eye floaters, it can be a bit alarming. But rest assured, they are completely harmless in most cases and will eventually go away on their own. In fact, many people never even notice them after a while.

If you’re concerned about your eye floaters, the best thing to do is see an eye doctor. They can determine if there’s anything serious going on, and if not, they can offer some advice on how to best deal with them. In the meantime, here are a few things that may help you cope:

– Try to relax. Remember that eye floaters are usually harmless and will eventually go away on their own.

– Avoid staring at them. This can actually make them appear more prominent. Instead, try to look at something else.

– Blink frequently. This can help to break up the floaters, so they’re less noticeable.

5. Can floaters cause blindness?

Floaters are usually harmless and do not cause any problems. However, in some rare cases, they can be a sign of a more serious condition such as retinal detachment and glaucoma.

6. Can floaters appear suddenly?

Yes, floaters can appear suddenly. However, they are usually not a cause for concern. If you experience a sudden onset of floaters, you should see an eye doctor to rule out any underlying conditions.

Question 1: What is vitrectomy?

Vitreous is the gel-like substance that fills the central portion of the eye. Vitrectomy is an eye surgery that is performed to treat the vitreous in the eye and other problems related to the retina. In this surgery, the damaged vitreous is replaced with another solution.

  • The surgeon will make small cuts in the sclera, that is the white part of the eye.
  • The vitreous is gently taken out along with any scar tissue present or any foreign material present from the eye.
  • The vitreous is then replaced with fluids such as silicone oil or saline.
  • For diabetes, any leaking blood vessels are sealed using laser treatment.
  • The surgical incisions are now covered with stitches.
  • An antibiotic ointment is then placed on your eye to prevent infection.
  • At the end, a patch is used to cover the eye.

  • On the day of operation, wear loose fitting clothes to avoid contact with the eye when getting dressed.
  • You will be prescribed different eye drops. Use them as advised.
  • In some cases, you may be advised to keep your head tilted downwards for 4-14 days. 

Question 7: What are the risks of vitrectomy?

Vitrectomy is mostly a safe and common eye surgery. However, just like any other surgery, there are some risks involved.  Some people may experience:

Insights on Refractive Errors by One of the Best Eye Hospitals in Kolkata

eye hospitals

Are you struggling to see clearly? It could be because of refractive errors, a type of vision problem. These eye problems occur when the shape of your eye keeps you from focusing well. The cause could be the shape of the eyeball or ageing of the lens. As one of the best eye hospitals in Kolkata, we share with  you important insights on refractive errors:

1. They are the most common problems: Refractive errors are the most common eye disorders. The most common symptom of refractive errors is blurred vision. Often, refractive errors can be easily treated. They are usually not serious but in some severe cases, they may cause visual impairment.

2. Symptoms of refractive errors: Besides blurry vision, the symptoms of refractive errors include: 

  • Double vision 
  • Hazy vision 
  • Squinting
  • Headaches
  • Eye strain (when your eyes feel tired or sore)
  • Trouble focusing when reading or looking at a computer

    3. Types of refractive errors: There are 4 types of refractive errors, namely:
  • Myopia
  • Hyperopia
  • Astigmatism 
  • Presbyopia

    4. Astigmatism causes blurred distance and near vision: This is a condition that involves an abnormal curvature of the cornea. This abnormal curvature can cause two focal points to fall in two different locations making objects appear blurry up close or at a distance. Astigmatism causes straining of the eye accompanied by myopia or hyperopia. This condition can be treated by wearing prescribed eyeglasses, contact lenses or corrective surgery.

5. Myopia makes objects farther away appear blurry: Myopia is a condition in which the image focuses in front of the retina instead of on it. It is also known as nearsightedness. This occurs due to the eyeball axis being too long than normal or due the refractive power of the eye being too strong. Myopia results in distant objects appearing out of focus and causes eye strain or headaches. Myopia can be corrected by wearing eyeglasses or contact lenses, as they correct vision by adjusting the focusing power. Corrective surgery can also treat myopia by shaping the cornea to a more spherical or round shape.

6. Hyperopia makes nearby objects appear blurry: Hyperopia is a condition in which the light or image focuses behind the retina instead of on it. It is also known as farsightedness. Hyperopia can affect people from all age groups and can also be inherited. In this condition, distant vision is clear while close vision is blurry. In advanced hyperopia, vision can be blurred at all distances. Like Myopia, this can also be treated and corrected by using eyeglasses, contact lenses or by performing a corrective surgery.

7. Presbyopia becomes noticeable usually in early  40s: Presbyopia can be termed as the ageing of the lens in the eye. After 40 years of age, the lens in the eye becomes rigid and there is a reduction in flexibility. This causes the eye to  lose its focusing ability and makes it more difficult to see or read from a close distance. This normal ageing of the lens can also be combined with myopia, hyperopia or astigmatism. Presbyopia can be treated using prescription glasses and contact lenses. However, if it is severe  and causing trouble then it is advised to undergo corrective surgery. 

8. Who is at the risk of developing refractive errors?   Anyone can have refractive errors, but you’re at higher risk if you have family members who wear glasses or contact lenses.

9. How are refractive errors diagnosed? A visual acuity test is done to diagnose refractive errors. The eye doctor will ask to read a vision chart while testing which lenses are the best to suit your vision. Special imaging or other testing is rarely necessary for refractive errors. 

Here’s a useful read on why wearing the wrong eyeglass prescription can cause problems.
