How to manage your eyesight when waiting for cataract surgery?

Following the pandemic, many things have taken a backseat and routine eye surgeries such as the ones for cataracts are no exception. This may mean to experience an extended period of delay in getting your cataract surgery. Though delay in cataract surgery doesn’t put your vision at permanent risk or doesn’t increase the risk of any surgery complications, it is important to take care of your eyesight while waiting for the surgery. As one of the leading eye hospitals in West Bengal, we share with you some important information on managing cataracts while you wait for surgery:

How to manage your eyesight when waiting for cataract surgery

 

  • Remove or reduce tripping hazards: When the vision is deteriorating, simple tasks inside the home can be hazardous. It is, therefore, important that you look around your home and identify things that may pose a tripping and falling hazard. Make sure your house has anti-slip rugs not just in bathrooms and kitchens but also in the living room and other areas. Ensure that there are no uneven surfaces and there is adequate lighting in the entryway and staircase. Remind family members not to leave objects in the walkways.

 

    1. Seek help to read: The cloudiness and sensitivity to light caused by cataracts can make reading difficult. If you are struggling with reading, audiobooks and podcasts are good alternatives. There are many popular newspapers and magazines that are available in digital formats wherein you can increase the font.
    2. Watch accessible TV shows: For many people, TV is an entertaining pastime. However, cataracts may interfere with it and make it difficult to see finer details. Watching shows with audio description is a great way to enjoy television without missing what is happening on the screen.
    3. Avoid harsh lights: Light sensitivity is a common symptom of cataracts. The glare of bright lights can be painful in some cases. Use thick curtains or blinds to block bright sunlight. Avoid the use of fluorescent lighting at home. Use warm white LEDs to cut the glare.

 

  • Quit smoking: Smoking has a direct negative effect on eyes. The free radicals in smoke from cigarettes and other tobacco products weaken the protein and the vital cell membrane of the eyes’ lens. You should try to quit smoking. You must also refrain from smoking immediately after the surgery.
  • Seek help with household chores: A healthy lifestyle is really important for your overall good health. If you are struggling with household chores such as cooking and cleaning, seek help from a friend or hire a professional. Eating a healthy diet and exercising regularly play an important part too in eye health.
  • Discuss your medications with your eye doctor: Let your eye doctor know of any medications that you may be taking for other health conditions. . Also, if you are struggling to see your medication, seek help from a family member to organise your medication in such a way that you can take them safely. Otherwise speak to your pharmacist and use a medication organiser, https://neurofitnessfoundation.org/xanax-alprazolam/.

 

After cataract surgery, vision can be significantly improved. Our experienced doctors at Disha Eye Hospitals perform cataract removal surgeries using the latest techniques and technologies for favourable outcomes. To know more about cataract surgery, get in touch with us.

Useful insights on blue light

Blue light is a part of the visible light spectrum; it can come from digital devices, fluorescent lighting solutions, and of course, the sun. Researchers have found that exposure to blue light at night from phones can disrupt your ability to fall asleep as blue light suppresses the secretion of melatonin, a hormone that tells us when it is time to sleep. In addition to disrupting sleep, blue light can lead to retinal stress, which can cause an early onset of age-related macular degeneration (AMD).  As one of the best eye hospitals in Kolkata,  we have curated a list of useful insights on blue light and its effect on our health: 

Useful insights on blue light

  1. Blue light affects sleep cycle: Exposure to artificial blue light closer to bedtime can disrupt the circadian rhythm —- internal process that regulates the sleep–wake cycle. During the day, blue light from the sun has been found to help people stay focused and alert. It also boosts memory and cognitive functions. However, when a person is exposed to blue light in the evening hours, the release of melatonin, the sleep hormone, is suppressed. Harvard researchers conducted an experiment where they compared the effects in people who were exposed to 6.5 hours of blue light versus 6,5 hours of green light. It was found that blue light suppresses melatonin for about twice as long as the green light.
  2. Blue light may cause eye strain: Often many people experience discomfort after looking at digital screens. This is called digital eye strain. When looking at screens, people often blink less. Blinking keeps the eyes moistened and cleans the surface of the eyes of any debris or dirt. When one blinks less, the eyes dry up which can lead to irritated and dry eyes. The best way to protect the eyes against digital strain is to take frequent breaks and blink more often.
  3. Use devices on night mode:  Digital devices come with a night mode that reduces screen brightness, which can reduce eye strain. The night mode reduces glare and helps your eyes adjust to the surrounding light.
  4. You get more blue light exposure from the sun than any other source: People often associate blue light with digital devices whereas the largest source of harmful blue light is sunlight. A study found that higher levels of  sun exposure in teenage and early adult years were associated with early age related macular degeneration. To protect your eyes from the harmful effects of the blue light, wear sunglasses that block 100% of both UVA and UVB light. Also, it is important to wear sunglasses throughout the year , even during winters. Here is a useful read on choosing the right types of sunglasses for your eyes. 

If despite cutting back on your screen time and exposure to bright light the eye strain persists, see an eye doctor to find out the causes and the solutions to protect your vision. If you are searching for the best eye hospital in Kolkata and other cities in West Bengal, visit the nearest branch of Disha Eye Hospitals. You can also book an online consultation.

Everyday Habits That Are Hurting Your Vision

The eyes are major organs and they need proper care and attention. However, often people take their vision for granted – they do things that might be damaging their vision. As one of the top eye hospitals in Kolkata, we discuss with you a few everyday habits that can hurt your vision and cause eye discomfort, pain, and even eye infection. 

Everyday Habits That Are Hurting Your Vision

Habit 1: Rubbing your eyes: 

  • This may seem like a harmless thing to do, but rubbing your eyes vigorously can actually affect your eye health.
  • When you rub your eyes, there is a chance of keratoconus – which can weaken the structure of the cornea. 
  • Every day your hands come in contact with many bacteria and germs. When you rub your hands with dirty hands, you increase the risk of transferring the germs into your eyes, thus increasing the risk of eye infection.

Habit 2: Too much screen time:

  • Staring at digital screens all day can cause eye discomfort.
  • During the  Covid-19 pandemic, the digital screen timings have increased as education, work and entertainment have moved online.
  • According to a study, nearly 23% of the Indian population saw their eyesight weakening due to the increased screen time during the pandemic. The study found that in 2020, the average Indian spent around 6 hours 36 minutes staring at a digital screen. 
  • When you are spending too much time on TV, browsing the internet, or staring at your phone, you’re less likely to blink, which means your eyes can get dry, red and itchy. 
  • To avoid dry and itchy eyes, follow the 20-20-20 rule. Every 20 minutes look at something 20 feet away for 20 seconds. 

Habit 3: Not wearing sunglasses outside

  • Extensive exposure to UV rays damages the retina, putting the eyes at the risk for eye conditions such as cataracts, macular degeneration, pterygium, and photokeratitis. 
  • Always buy sunglasses with UV protection.

Habit 4: Wearing old contact lenses or not storing them properly 

  • Wearing old contact lenses increases one’s risk of suffering from eye infections. 
  • Other reasons for eye infections include sharing contacts with others, sleeping in your contacts, and wearing ill-fitting contact lenses.
  • Store and keep your contact lenses in a hygienic way. Keep the case clean and replace the case every 3 months. 
  • Wearing contact lenses while showering or swimming can cause eye infections.

Habit 5: Using expired eye makeup

  • Discard expired eye makeup. Using expired or old eye makeup can lead to eye irritation and infection. 
  • Before applying an eye makeup product, always check its expiry date.

Habit 6: Skipping regular eye exams

  • Regular eye checkups can help in the early detection of eye conditions. Some eye conditions do not show any early signs and they can be detected only through comprehensive eye exams.

Note: If you are looking for a top eye hospital in Kolkata for an eye check-up, visit or book an online appointment with Disha Eye Hospitals.

Habit 7: Uncontrolled smoking

  • Smoking is injurious to health. It can cause health problems such as cancer or lung disease and can also harm your eye health. 
  • A few of the eye conditions related to smoking are glaucoma, cataracts, dry eye, and macular degeneration. Gradually quitting smoking can help save your vision as well as your overall physical health.

A useful guide on LASIK

A type of refractive eye surgery, LASIK stands for laser-assisted in situ keratomileusis. The procedure can correct refractive errors — nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. As the surgery has a good track record, it is often chosen by many patients. The procedure is safe and quickly restores the vision.

A useful guide on LASIK

Requirements for a good LASIK surgery candidate:

1. Candidate’s eyes should be healthy: The eyes should be healthy. If there’s any active eye infection or abrasions, they must be treated before the surgery.

2. The eye condition is within range: LASIK eye procedures treat a wide range of eye conditions, including hyperopia, myopia, astigmatism. An eye doctor is the best person to tell whether LASIK is the best treatment for a particular eye condition or not.

3. The vision should be stable: Stable vision reduces the risk of regression and the need for a touch-up procedure. 

4. The candidate should be an adult: The patient has to be at least 18 years old to undergo LASIK surgery.

What is the procedure for LASIK?

Before a LASIK procedure, the eye surgeon will/may:

  • Assess the overall health of the eye. 
  • Prescribe mild medication a few days before the procedure. 
  • Put numbing drops in the eyes before the operation starts.

LASIK treatment:

LASIK surgery can be performed with Excimer Laser as well as Femtosecond laser. While the former uses a blade during the procedure, the latter is a bladeless procedure.

The laser physically corrects the glass prescription by reshaping the cornea during the surgery. Thus, correcting myopia, hypermetropia or astigmatism using this technology.

The LASIK surgery usually requires less than 30 minutes of operating room time. The laser is for less than a minute on each eye. However,  preoperative preparation and post-operative observation may take hours.

LASIK with Excimer Laser

The procedure involves two steps:

  • Creation of thin-film or flap on the surface of the cornea by a precision flap-making instrument
  • Reshaping the cornea with excimer laser by removing tissue from the middle layer of the cornea

The procedure in detail:

  • After numbing the eyes, the patient is asked to relax on the treatment bed. The eyelids of the patient are held open with a precision flap making instrument, microkeratome. It is an extremely fine instrument with precise delicate gears.
  • The patient is then asked to focus on a special fixation light. The eye surgeon uses a precision instrument. The instrument folds away a corneal flap within seconds, revealing the middle layer of the cornea.
  • During the creation of the flap, the pressure in the patient’s eye rises and their vision may grey out.
  • The cornea is reshaped using an excimer laser. 
  • After this, the flap is returned to cover the exposed area. And the treatment is completed.
  • Eye drops are put in the eye and a shield will be placed to keep the eye protected.

LASIK with Femtosecond Laser

The following steps are followed on the day of surgery: 

  • The patient is brought to a procedure room and is asked to lie on their back under the laser system and a computer screen.
  • Numbing drops are put into the patient’s eyes. 
  • The patient’s eyelids are kept open during the procedure using a machine called eye speculum.
  • A suction ring is centered over the pupil and suction is applied. A glass lens holds the globe of the eye steady and flattens the cornea.
  • The laser is used to create a flap in the surface of the cornea and suction is released.
  • The cornea is reshaped as required.
  • The flap is replaced once reshaping is complete. 
  • The flap will heal without stitches.

Note: If you are looking for the best eye hospital in Kolkata for bladeless, femtosecond LASIK surgery, you can visit us. We, at Disha Eye Hospitals, are committed to providing our patients with the highest possible standard of ophthalmic care in an affordable manner. Along with LASIK surgery, a few of our other services include cataract surgery, glaucoma treatment, diagnostic and imaging services.

Although each of the LASIK procedures has its own features and benefits, there are a few advantages of femtosecond laser LASIK:

  • Puts patients at greater ease as no blade is used during the process
  • The decreased potential risk of corneal abrasion
  • Helps surgeons to customize LASIK procedure
  • Creates corneal flap with edges, enabling it to fit securely in place after the LASIK procedure, decreasing the risk of dislocation of flap post-surgery

What to do after LASIK surgery?

After LASIK surgery:

  • The patient should avoid rubbing or squeezing their eyes for the first week. 
  • They should take care of the eye to ensure that they do not displace the flap.

Why are dry eyes an increasing problem?

If you’ve ever experienced irritation, itching, or scratching sensation in your eyes,  you are not alone. These are the symptoms of dry eyes. Dry eyes is an eye syndrome that occurs when tears fail to provide adequate lubrication to the eyes. 

Why are dry eyes an increasing problem

Dry eyes may sting or burn. In some cases, dry eyes are uncomfortable, disrupting day-to-day activities. Dry eye syndrome is on the rise, affecting around 344 million people across the globe. 

Note: We, at Disha Eye Hospitals, are equipped with state-of-the-art diagnostic equipment to help diagnose and treat dry eye syndrome. We have some of the best doctors, ophthalmologists, and eye surgeons in Kolkata on board .

Causes of dry eye: 

  • Weather conditions: Different weather conditions, such as cold climate and exposure to winds can result in tears evaporating too quickly, further leading to dryness in the eyes. Dry air can also lead to dry eyes. 

 

  • Air conditioning: Today, air conditioners have become a part of homes and offices, especially in areas with high humidity. While air-conditioned homes and offices make your indoor environment more pleasant, it also drains the humidity from the air, resulting in loss of moisture in the eyes. This can result in dry eyes. 

 

 

Extended screen time: One of the noticeable and recent effects on eye health is extended screen time. Blinking helps in keeping the eyes lubricated. When people look at a screen for extended periods, they tend to blink less. This causes faster evaporation of the film of tears that protects the surface of the eye, leading to dry eyes. 

 

Wearing contact lenses: Contact lenses can also put one at risk of dry eyes. Wearing contact lenses for more than the recommended hours per day can increase the risk of developing dry eyes.   Not handling contact lenses properly can result in dry eye issues and can also exacerbate dry eye symptoms for those who are already suffering from the condition.

Things to know about an eye strain headache

People often experience eye strain. The term is often used by people to describe symptoms such as mild pain or discomfort in the eye. Usually, eye strain occurs when your eyes get tired due to overuse, such as driving for a long period of time or staring at the computer or mobile screen for too long. This can cause discomfort.  Eye strain is also known as asthenopia or ocular fatigue. Eye strain can sometimes also trigger headaches, the severity of which depends on the cause. They are known as eyestrain headaches. 

eye strain headache

Eye strain headaches are basically the pain behind one’s eyes. Below we share a few signs of eye strain headache:

What are the signs of eye strain headache?

  • Dry eyes
  • Sensitivity to light
  • Blurry vision
  • Sour eyes
  • Watery eyes
  • Neck, shoulder or back pain

What causes eye strain?

  • Continuous use of the digital screen: Staring at a digital screen for a long period of time is the most common cause of eye strain. 

When you focus on the screen, you blink less often, which can lead to dry eyes and cause irritation  

  • Prolonged focus on a single task: Your eyes get tired when you continually focus on a single activity for a long time, for instance, driving, reading a book or even drawing.

 

  • Vision problems:  You may experience eye strain if you have vision problems. When you have problems such as nearsightedness or farsightedness, your eyes work harder to see things, making the eyes tired and leading to an eyestrain headache. 

 

 

  • Bright or dim lights: If the light is too bright or too dim, it is difficult to see clearly. Trying to focus in such situations is tough, making your eyes tired and strained.  

How to prevent eye strain?

  • Follow the 20-20-20 rule:  Try to take frequent breaks when using digital screens. According to this rule, look at something at least 20 feet away for around 20 seconds every 20 minutes.
  • Avoid using digital screens in the dark: Your eyes need to do extra work when you stare at a digital screen in the dark, making your eyes tired sooner than they should. Therefore, avoid using a digital screen in the dark.
  • Blink often: Blink more than you do now.  Blinking moisten your eyes, keeping the risk of dry eyes away.
  • Keep your screen at a distance: Always  your screen at least 25 inches away from your eyes and position it slightly below eye level.
  • Do not wear eye contact lenses for a longer period of time: Wearing contact lenses for a long time can cause eye irritation and strain your eyes. 
  • Adjust the brightness of your digital screen: Make sure that your screen is bright enough to not have shadows, and also not too bright that it’s hard to discern contrast.
  • Keep your surroundings clean: Keep your surroundings free from dust, which can disturb your tear ducts and lead to dry eyes.
  • Get enough sleep: Try to get around 6-8  hours of sleep. Stay hydrated and drink up liquids to avoid dry eye discomfort.
  • Wear anti-reflective lenses: The best way to save your sensitive eyes from eye strain from digital screens is to wear anti-reflective glasses. 
  • Get regular eye checkups: Weak vision can cause headaches, eye strain and blurred vision. So, even if you don’t have any eye problems, you should visit an eye specialist and have your eyes examined at least once a year.

Looking for an experienced eye specialist? 

Getting your eyes checked by an eye specialist regularly can help stop vision problems from getting worse.

Cataract Surgery And Your Options

Cataract surgery is one of the most common and safest surgeries performed around the world. Approximately, 10 million cataract operations are performed each year in the world with a high success rate.

What is cataract surgery?

Cataract surgery is the procedure of replacing the lens of your eyes with an artificial lens. A cataract is clouding of the natural lens of the eye. The surgery is carried out to remove the damaged lens and replace it with an artificial lens. It is usually performed under local anaesthesia  where the patient will be awake but will not feel any pain during the procedure. 

Cataract surgery and your options

Benefits of cataract surgery 

1. Improves vision

2. Helps in seeing things in focus

3. Improves the quality of life

4. Protected eye health

Here we have shared a few things you should consider while opting for cataract surgery:

 

  • Deciding on the time for surgery: Cataracts are removed when it makes it difficult for the person to carry out normal activities, such as driving or reading. An ophthalmologist is the best person to suggest the best time for surgery.
  • Pre-operative assessment: An eye doctor carries out a pre-operative assessment before the surgery.

1. The general health evaluation of the patient includes checking the patient’s blood pressure levels, current medication, allergies, and other medical conditions. 

2. The doctor will further check the visual acuity of the patient. The refractive errors, dioptric error, and intraocular pressure of the eye are also measured before the surgery. 

 

  • Choosing the type of intraocular lens: Another option you need to consider for your cataract surgery is the type of intraocular lens (IOL). The doctor will remove your natural lens and replace it with any of these types of IOLs:

 

 

1. Monifocal lens

2. Multifocal or accommodative lens

3. Toric lens

What is vision correction cataract surgery? 

While undergoing cataract surgery, the surgeon can also correct the vision, giving the patient better vision he or she had before the surgery.

Why should you not ignore blurry vision?

Does your vision sometimes appear blurry? Often, people do not take blurry vision seriously. However, the fact remains that blurred vision can be an indication of an eye problem.

blurry vision

As one of the leading eye hospitals in West Bengal, we do not take complaints of headaches and blurry vision lightly. We advise our patients to get an eye examination if they experience any changes in their vision, be it a blurry vision, double vision or seeing spots.

Blurry vision: Why should you visit an eye hospital?

Well, not all causes of blurry vision are a reason to worry. Many vision problems are treatable with medications and eye drops or prescription eyeglasses. However, in some cases, blurry vision can be a sign of a serious eye condition and if left untreated for long, it may cause irreversible damage to your eyes.

 

Here we discuss some of the eye problems that can cause blurry vision:

Blurry vision can be a sign of the following vision problems:

  • Refractive errors: Refractive errors, such as near-sightedness, far-sightedness, or astigmatism are some of the most common causes of blurry vision. It occurs due to a change in the shape of the eye that causes vision to become blurred. If corrective measures are not taken, these eye problems can deteriorate your eyesight slowly. Using eyeglasses or contact lenses prescribed by an eye doctor can correct refractive errors.
  • Glaucoma: One of the many symptoms of glaucoma is blurred vision. It is a common age-related vision condition that usually affects people over 60. The eye condition damages the optic nerve by causing abnormally high pressure in the eye. Diabetic people are twice as likely to develop glaucoma than non-diabetics. High blood sugar levels cause the blood vessels to bulge. Glaucoma is one of the leading causes of blindness after cataracts and trachoma. As glaucoma doesn’t show any early signs of vision problems, it is important to get your eyes checked regularly. Treatment includes prescription eye drops, medications, laser treatment, or surgery, depending on the severity of the condition, https://medfitnetwork.org/public/ambien-zolpidem-info/.
  • Cataracts: Blurry vision is the most common symptom of cataracts. People with cataracts usually find it difficult to read or drive at night. If left untreated for a long time, cataracts can cause blindness. Cataracts can be removed with surgery – where the damaged lens is replaced with an artificial lens. Here are some frequently asked questions on cataracts that will help you understand the condition better.
  • Eye infections: Blurry vision can be caused due to eye infections – which also cause redness, itching, and swelling. Though not all eye infections are serious, seeking early treatment is the best to prevent any risk of irreversible vision damage.
  • Diabetes-related eye conditions: Diabetes can lead to blurry vision in many ways. If you have diabetes, you’re at an increased risk of suffering from diabetic retinopathy, macular edema, cataract, and glaucoma. High blood sugar levels cause the lens of the eye to swell. This makes it difficult for the eyes to focus, so things may look blurred.

Consult the best eye doctors in Kolkata at Disha Eye Hospitals

If you suddenly start to feel any change in your vision, get your eyes checked for correct diagnosis and treatment. We offer diagnosis and advanced treatment for patients with a wide range of vision problems. Book an online consultation or call for an in-person visit.

What is retinal artery occlusion?

A very rare eye condition, retinal artery occlusion (RAO) is an ophthalmic emergency, which often results in acute vision loss. In the United States, the incidence of vision loss due to retinal artery occlusion is 1 to 2 cases per 100 000 per year. The patient with RAO requires prompt medical attention and should be transferred to a stroke centre. Retinal artery occlusion refers to the obstruction or blockage of blood to the retina of one eye, causing vision loss.

As a leading eye hospital in Kolkata, we share with you insights on this rare eye disease.

eye hospital

What are the risk factors?

Anyone who is old or has other medical conditions such as diabetes, glaucoma, high blood pressure are at higher risk to have RAO. Here we have listed down a few of the risk factors:

  • Old age
  • High cholesterol 
  • Male 
  • Heart disease
  • Smoking
  • Damage from radiation treatments 
  • Birth control pills
  • Hypertension
  • Obesity
  • Cardiovascular disease

Symptoms of retinal artery occlusion:

One of the main symptoms of eye stroke or retinal artery occlusion is a sudden painless change in vision. It often happens in only one eye. 

Apart from a sudden change in vision, one may notice the following signs or symptoms:

  • Blurry or distorted vision
  • Blind spots
  • Sudden blindness of one eye

How is the eye condition diagnosed?

  1. The condition is diagnosed by a dilated eye examination. 
  2. The retinal artery occlusion is an area with retinal whitening along the blocked blood vessel. This whitening lasts for around 4 to 6 weeks before it starts fading away.
  3. Fluorescein angiography is employed to record the blood flow in the retina. It shows a delay in filling the retinal arteries.  
  4. Optical coherence tomography gives detailed images of the central retina. It shows the swelling in the inner layers of the affected area. 
  5. The eye doctor may check the other medical conditions of the patient that are related to retinal artery occlusion.

Treatment for retinal artery occlusion:

Retinal artery occlusion has no clinically proven treatment. However, several therapies are used to treat RAO, including:

  1. Hyperventilation— In this therapy, the patient is made to inhale carbogen — a mixture of oxygen (95%) and carbon dioxide (5%). Through this, the eye doctors attempt to dilate the retinal arteries and make the blood clot move.
  2. Paracentesis: In this procedure, fluid is removed from the front of the eye using a small-gauge needle. It is done to lower the intraocular pressure to further dislodge the blood clot.
  3. Using different medications to lower the intraocular pressure.
  4. Giving an ocular massage with a thumb to move the embolus.
