Things to know Before Choosing a Cataract Surgeon

Selecting a surgeon to operate on your cataracts is a big decision that requires time and effort.  As with any surgeon it is important to research your option including the procedure and the surgeon performing it.  Our eyesight, without any doubt, is one the assets we are blessed with.  If there is a need to undergo cataract surgery, one shouldn’t just rely on just anyone.  Selecting the best cataract surgeon is vital if you want to undergo a risk-free surgery.

Considerations Prior To Cataract Surgery

  • Don’t Rely Only on Your Insurance Companies Recommendations

For people who have insurance they most often rely on the doctors and surgeons suggest by their insurance company.  However, when it comes to a crucial surgery such as cataract surgery, it is important for the patients to do their research and find the best surgeon for their specific needs.  This is not to rule out that your insurance company is not offering a reliable option, but it is advised to evaluate several options before making a final decision on a surgeon.

  • Seek Expert Advice

When looking to find the best cataract surgeon, it is important to seek expert advice. You can take suggestions from your regular physician or any friend/colleague who has recently undergone such a surgery. This will help you have numerous options at your disposal. Thus, selection will become an easier task.

  • Do a Background Check

After finalizing a list of potential surgeons for your treatment, you must do a background check on them. Ensure that they are board certified. It is necessary for a surgeon to obtain such a certificate after passing both oral and written exams. Apart from board certification, you must also check whether they are licensed to perform surgery in your state or not. It is also important to know how many surgeries they have performed in the past.

Moreover, with a little research on the internet, you can also get to know about their education. If possible, check the rankings of the institute they have got their education from and got their training.

  • Current Reviews and Patient’s Experience

You can use the internet to check for your selected cataract surgeon reviews. There are numerous platforms on the internet that can help you to find such information. If possible, ask for experiences of the patients who are treated by that surgeon.

  • Schedule an In-Person Consultation

Last but not the least, you should meet your selected surgeon in person before taking the final decision. Discuss important matters related to this surgery with them. It will help to develop a sense of confidence in you. Trust factor will build up. Therefore, preparing yourself for the surgery will rather be an easy task.

After considering all the factors above, you will finally be able to take the decision that will be in your best interest. This will require some time, effort, and dedication on your part to find the best cataract surgeon; however, the result will definitely be valuable.

LASIK Surgery Now Extremely Effective for Astigmatism

“I can’t say how many times I have been told by patients that they would love to have LASIK if only it weren’t for their astigmatism. I’m always happy to let them know this simply isn’t true,” stated Marc S. Werner, M.D.

GARDEN CITY, N.Y. December 27, 2017

There are many urban legends surrounding LASIK (laser in-situ keratomileusis) or laser eye surgery, and the experienced doctors at Stahl Eyecare Experts on Long Island and New York City have heard them all. One of the most common myths about LASIK is that people who have astigmatism cannot have the procedure, and must wear glasses or contact lens for their whole lives.

“I can’t say how many times I have been told by patients that they would love to have LASIK if only it weren’t for their astigmatism. I’m always happy to let them know this simply isn’t true,” stated Marc S. Werner, M.D. at Stahl. “LASIK is now extremely effective for 99.5 percent of those with astigmatism. In fact, those who have LASIK to correct astigmatism often have a better quality of vision after surgery than before with glasses or contacts.”

The doctors at Stahl are truly experts in the field of LASIK – they have performed more than 50,000 procedures throughout Long Island and in the five boroughs of New York City, and Stahl Eyecare Experts has been on the cutting edge of ophthalmology for more than 50 years.

“The LASIK procedure only takes about five minutes to complete and is the safest of all surgeries performed in the world,” said Thierry Hufnagel, M.D., one of Stahl’s board-certified eye physicians and an instructor in IntraLase™ bladeless LASIK surgical technique.

The IntraLase™ method delivers outstanding results and has been shown to improve outcomes for more patients. Stahl Eyecare Experts was the first private vision eye center in New York to offer patients the iFS™ Femtosecond laser system, a technological breakthrough for the IntraLase™ method of performing LASIK surgery. With All-Laser iLASIK performed at Stahl Eyecare Experts, no metal blade is used, offering a premium level of safety and accuracy, making it even better for those with astigmatism. Thanks to iLASIK, most people who meet the general age and health requirements are candidates, and iLASIK has earned FDA approval to treat the broadest range of vision imperfections including nearsightedness, farsightedness and astigmatism.

Dr. Oz: Cataract surgery and the elderly

In this Saturday, Nov. 3, 2012 photo, a volunteer examines the eye of a patient prior to her cataract surgery at a military hospital in Padang Sidempuan, North Sumatra, Indonesia. Indonesians flocked to the hospital for free cataract surgery performed by a team led by Nepalese master surgeon Dr. Sanduk Ruit who is renowned for his high-volume assembly-line approach. During the eight-day eye camps held in two towns in North Sumatra, more than 1,400 cataracts were removed. (AP Photo/Binsar Bakkara)

Q: My 87-year-old mother has a cataract in one eye and is developing another in the other. Her doctor says she should have surgery, but at her age, I’m worried about the operation. What’s your advice? — Edie C., Beaver Falls, Pennsylvania

A: If her overall health is good, the surgery should not only improve her quality of life, but could extend it, as well. A new study based on data from the Women’s Health Initiative found that cataract surgery was “associated with decreased risk for all-cause mortality.” “All cause” means everything from cardiovascular disease to cancer.

The team of researchers, assembled at UCLA and including docs from across the U.S., recently published their findings in JAMA Ophthalmology. They looked at more than 20 years of data that included 74,000 women 65 and older, 40,000 of whom had cataracts.

The scientists found that seeing an ophthalmologist and maintaining your vision (cataract surgery) was associated with better cognitive function and a longer life. One obvious reason is that an older person’s risk of falling is greatly reduced with improved vision. Falls are the leading cause of death among people 65 and older, accounting for around 9,500 deaths annually. Also, when you can see better, you’re happier, more active, more able to read, play games and interact with the world — all fuel for keeping the body healthy and the brain sharp.

So for your mom, the next step is to find a good eye surgeon. We suggest getting referrals from her doctor and friends who have had the procedure done; then talk to the surgeons. Ask about their complication rate. Even though the procedure has an overall success rate above 98 percent, there are risks. In the U.S., the lifetime risk of a detached retina as a complication is about 1 percent. That number rises to about 2 percent if there is some cloudiness on the lens post-surgery that’s cleaned up with YAG laser capsulotomy. But chances are Mom will sail through with flying colors — that she’ll be able to see!

Dr. Mehmet Oz is host of “The Dr. Oz Show,” and Dr. Mike Roizen is Chief Wellness Officer and Chair of Wellness Institute at Cleveland Clinic. Email your health and wellness questions to Dr. Oz and Dr. Roizen at youdocsdaily@sharecare.com.

Local woman’s eyesight saved by laser surgery

Clair (left) and Mary

A Carnoustie woman’s sight has been saved by laser surgery following a retinal tear.

Mary Heywood visited Specsavers in Arbroath as soon as she began to experience flashes and floaters in her vision. An exam revealed Mary had a condition called posterior vitreous detachment in one eye.

She was advised to contact the shop immediately if her symptoms worsened.

A few days later, her symptoms deteriorated, so principal optometrist Clair Donaldson saw her that same day and discovered a retinal tear had developed.

She said: ‘Thankfully, Mrs Heywood followed our advice and did the right thing by arranging another exam.

“If she didn’t have it checked out, there is a high chance she would have developed a retinal detachment and suffered permanent vision loss.”

Mary said she was immediately referred to the Hospital Eye Service at Ninewells Hospital in Dundee where she had laser treatment.

She said: “Shortly afterwards, I developed the same symptoms in my other eye and returned to the hospital for further laser treatment. Both were successful.”

Mary has shared her experience because she wants to warn others not to be complacent about their vision and to “book an appointment if you experience anything out of the ordinary”.

New laser surgery to get blue eyes emerging

SAN FRANCISCO, Nov. 22 (Xinhua) — People who want to turn their eye colors blue permanently now have a chance as a U.S. medical company has promoted a new laser surgery to achieve the change.

Stroma Medical, a U.S. company based in southern California, has helped at least 37 patients to change their eye color from brown to blue with a laser surgery in around 20 seconds, according to an online report posted on Tuesday.

The laser works to eliminate the brown melanin — the pigment which dyes hair and skin — from the surface of the iris.

Without the brown melanin, when light consequently enters and scatters in the stroma — the little fibers look like bicycle spokes in light-colored eyes, blue eyes appear.

In an earlier interview with CNN, the company’s representative Dr. Gregg Homer said the laser is so weak that the eyes won’t bear injuries from it. Nevertheless, the medical industry and ophthalmologists still raised concerns about the irreversibility of the surgery.

Though the surgery currently stands at a price as high as approximate 5,000 U.S. dollars, many netizens asked for more information on the company’s facebook. Some are eager to see the technology released in London and Mexico.

However, the new laser is in clinical trials, Stroma Medical said in their most recent reply on Facebook on Nov. 3.

So far, the company’s website has been hung up. It said a new website will be launched soon.

Early reports said the new technology is yet to gain approval from U.S. regulatory bodies.

It seems that blue eye seekers have to wait longer until the new laser is more advanced and gains wider acceptance.

Laser Eye Surgery: All you need to know!

Deciding to get laser eye surgery can often be a huge decision, not helped by some common myths surrounding the process and the potential side effects.

But, regaining your sight can also be one of the most rewarding things you’ll ever do, so we thought we’d bust those myths (and horror stories!) and find out what really happens if you opt for surgery.

Mr David Allamby is a specialist laser eye surgeon and founder of London’s Focus Clinic.

He’s not only one of the most respected vision experts in the world, but he’s also treated a host of celebrities, including model David Gandy, Olympian Victoria Pendleton, TV host Laura Whitmore and Love Island’s Scott Thomas.

Here, he lifts the lid on everything you ever needed to know about surgery to correct vision:

How does it work?

The most popular form of laser eye surgery is called LASIK – aka ‘laser-assisted in-situ keratomileusis’. It works by changing the curvature of the cornea, the transparent, curved window at the front of the eye. Something called an ‘excimer laser’ evaporates a really thin layer of collagen within the upper layers of the cornea and surgically reshapes the overall dome.

This means light entering at the front of the eye comes to a clear focus on the retina at the back of the eye, ensuring you can see clearly. And several studies have shown that once the shape of the cornea is adjusted, the change is ‘permanent’.

Will I ever need to wear contacts / glasses ever again?

It’s a common myth that surgery will ‘wear off,’ but your surgery for short-sightedness should last many, many years or indeed for your lifetime. The same applies for correcting astigmatism.

Long-sightedness and the need for reading glasses are age-related problems, and so re-treatment may be needed in the future.

At our clinic, we give short-sighted patients a ten-year guarantee on their laser surgery – ten times longer than other clinics.

So, in the extremely rare circumstance that you require re-treatment in the first 10 years post-treatment, the cost of the repeat surgery is free!

Might I need to wear reading glasses?

As we age, the lenses in our eyes lose some of the elasticity that lets them focus on objects up-close. This is just part and parcel of growing old and known as ‘presbyopia’, and is the reason why many people aged 40 and over will need reading glasses.

But there are solutions.

We offer two techniques that can help patients already suffering from presbyopia—the ‘LASIK Blended Vision’ procedure, or alternatively Refractive Lens Exchange (RLE). The choice will depend on your age and prescription.

Also, contrary to common misconceptions, if you’re under 40, LASIK surgery will NOT cause you to need reading glasses prematurely.

How long does the procedure take? 

The laser aspect of the surgery lasts for just a few minutes per eye and takes around 10 minutes in total.

The rest of the time—your appointment will last for about 90 minutes—simply involves the surgeon carrying out a series of checks to ensure complete accuracy.

After surgery, you’ll spend about twenty minutes in a patient recovery room, essentially relaxing while eating tea and biscuits!

How long is recovery time / will I need much time off work? 

With LASIK, most patients have a little discomfort immediately after surgery, as your eyes need a few hours to heal.

You’ll also need someone to drive you home or help with a taxi, too, and you should rest up for the remainder of the day. If in London, you mustn’t use the tube on the way home, to avoid dust or dirt being blown into your face.

Your eyes might also feel a little dry and scratchy, though this won’t last long and eye drops can relieve the symptoms.

You’ll have a follow-up appointment at the clinic the following morning after surgery, and most people are then able to return to work immediately afterwards.

Do I have to stop wearing contact lenses pre-surgery?

Contact lenses can alter the shape of your corneal surface, so it’s important you take them out long enough for your cornea to return to its natural shape before surgery.

Typically, if you wear regular soft contact lenses or extended wear lenses, you’ll need to take them out a week before surgery.

But if you wear Rigid gas permeable (RGP) lenses, and have been doing so for some time, you might need to go without contacts for 4-8 weeks before coming in for your treatment.

It’s also fine to switch to soft lenses for most of this time if you’d rather not wear glasses for that long.

How long will it take after the surgery for me to be able to see?

Most patients who have LASIK will have good vision straight after surgery. However, in some cases, it can take up to 24 hours for your 20/20 (or better) vision to come into effect.

It’s also important to remember that laser eye surgery doesn’t hurt. Most patients don’t find it an uncomfortable procedure, more strange and rather ‘sci-fi’!

How do they stop your eyes from blinking during the surgery?

During surgery, your eyes are gently held open by a device which makes sure you can’t blink.

You’re given anaesthetic drops so that you don’t get any pain, and it’ll feel like you’re blinking normally, even though your eyelids aren’t opening and closing. The muscle to blink still twitches, but the lids don’t close.

Some people worry that if they move—or sneeze!—it will affect the results. But it’s impossible to do so. During the time the laser is running, sophisticated tracking technology rapidly analyses the position of the eye to make sure it’s always in exactly the right position.

And this all takes place faster than you can physically move your eyes anyway. All you have to do is look at the flashing green light directly in front of you and your surgeon will do the rest.

What happens if something goes wrong?

As with everything, when you’re choosing a surgeon you need to think carefully and check their results. You should ask questions like, “What percentage of patients get 20/20 vision after surgery?”

Be aware that the main risk in laser eye surgery is a surgeon who selects and treats people who aren’t actually good candidates for surgery in the first place.

You should choose a specialist surgeon who works in a lower volume setting, and who can, therefore, take the time to properly assess and treat you.

As with any surgery, there are potential risks, but treatments are available for almost all complications that affect your vision.

Serious complications with LASIK are actually very rare if the patient is well selected.

The chance of having a significant complication affecting your vision (in one eye or the other) from LASIK is around 1 in 10,000. The risk of infection is even less, at 1 in 20,000.

What precautions do I need to take following the surgery? 

It’s bad news if you like swimming or hot showers—we recommend avoiding getting water in your eyes for the first 48 hours after surgery and you should keep away from saunas and steam rooms for around two weeks.

You should also skip sporting activities for the first week after treatment, which will give your eyes time to heal properly. As for flying, you can take short-haul flights the next day after surgery and you can travel long-haul around a week after treatment.

Cataract Surgery Procedure and What to Expect

Cataracts are one of the most common eye-related problems in the world today. It occurs when the eye lens becomes cloudy, leading to misty and hazy vision. Occurring naturally due to age, anyone that develops cataracts will eventually see a significant loss of clear vision, which can only be addressed through surgery.

Cataract surgery happens to be a very straight-forward procedure. Completed on hundreds of thousands of patients annually, cataract surgery helps to restore vision, preventing blindness from eventually developing.

Here’s everything you need to know about cataract surgery:

When is cataract surgery necessary?

A loss in vision is common in aging people, with many suffering from cloudy vision at some stage of their later years. Cataracts can take years to fully develop however, allowing people to live with it for quite some time before vision is impaired.

However, cataracts eventually develop into a much more significant problem over time. The only way to rectify the issue is by surgical procedure, where the cataracts are removed from the eye.

Should your vision not be impaired by cataracts, then you can hold off on surgery. It’s only truly necessary once it starts to have a negative impact on your day-to-day life. For instance, if you can no longer read, drive, or struggle to see in most conditions, then surgery is advised.

What does cataract surgery involve?

Cataract surgery is quite a simple routine. You are provided with some local anaesthetic and some eye drops, after which the eye surgeon makes a minor incision on your eye. If you are feeling anxious about the procedure you may be given a minor sedative to stay relaxed.

The eye lens is then removed and replaced with an artificial implant lens known as an intraocular lens, after which the surgery is complete!

What you can expect from cataract surgery

There are a few things to expect from cataract surgery, none of which should give you any concern.

The procedure is very simple and shouldn’t take longer than an hour, so expect a total surgery time of around 20-40 minutes in most cases. Only one eye is treated per surgery, so you will likely require two procedures should you have it in both eyes, which will take place a few weeks apart.

So, you can also expect to go home that day. Remember, you are only under local anaesthetic, which means you will be awake for the entire procedure. Don’t worry; you won’t be able to feel a thing! Most patients are home just a few hours after surgery, so it’s not too taxing of a day.

Also, your vision may be quite blurry for a few days after the surgery, although some people see their vision improve that same day. Don’t have high expectations of this however, as it’s best to assume you will need a few days to fully recover.

Are there any risks with cataract surgery?

Serious risks from cataract surgery are very low. The procedure is one of the safest and most straight-forward administered to patients, although there are some minor risks worth knowing. For instance, inflammation in the eye may occur, while more serious problems such as a detached retina are possible.

However, chances of complications remain low. Serious complications are reported in around 1 percent of cataract surgeries, so you should be completely free of risk!

At Rohr eye and laser center we offer cataract surgery with Tecnis IOLs or Toric IOLs. Don’t let cataracts affect your vision. We recommend you get a eye exam each year to insure your eyes are healthy. If you are worried about your vision and need a check up or would like to schedule a surgery, give us a call at 877-579-0202. You can also visit our website at www.michiganlasik.com.

Reasons Why a Yearly Eye Exam Are a Good Idea?

Most people think nothing of scheduling regular visits with the medical doctor or their dentist in order to make sure that they are physically fit and healthy and that their teeth stay white, bright, and cavity free.   When it comes to eye care however they tend only to seek the services of an optometrist when they have concerns regarding their vision.  The truth though is that everyone should have a yearly eye exam.

Eye Exams Are Important

A comprehensive eye exam is more than simply checking your vision to see if you need glasses or not.  During a comprehensive eye exam your optometrist will check your eye pressure, your eye muscle coordination and both the internal and external health of your eye.  A comprehensive eye exam is especially important if there is a family history of eye problems such as high blood pressure, diabetes, or other health issues that could be affecting your vision.  Yearly exams are especially important for those suffering from diabetes as catching diabetes-related eye problems in their earliest stages may help to save your vision.

Your optometrist can also spot problems caused by your eyes being exposed to too much ultraviolet light from the sun, from pollution, or dust particles in your work environment.  They are trained to give you tips on eye care and things you can do to help protect your vision.

In some cases, a yearly exam may not be enough.  If there are specific eye problems that can cause a rapid deterioration of your vision your optometrist may want you to have your vision checked every four to six months to keep a check and make sure that your vision is remaining stable.

When you consider how important your vision is to you and all the things you would miss if you lost your sight then you will realize how important proper eye care and those yearly eye checkups are to you and every member of your family.

Exams For Your Children

When it comes to children proper eye care is also important and you should have your infant have an eye exam at about six months of age, again at three, and then starting when they are school age they too should have a yearly exam unless there is some reason why checkups should occur more often.

Children who suffer from undiagnosed vision problems often not only have more severe vision problems later in life but also tend to do poorly in school.  By getting yearly eye exams for your child from the time they are young you will be protecting their eyesight both now and in the future.

Make Sure to Do Exams Annually

If you have not had an eye exam lately you should call your optometrist now and set up an eye appointment.  Follow through with eye exams each and every year.   Your eyesight is important to you and the only way to protect your eyesight is with proper eye care.

If you are looking to reduce or even get rid of your eye glasses and/or contacts let us at Rohr Eye & Laser Center help you!

Newcastle scientists eye-up cornea ‘breakthrough’

Artificial corneas have been grown using a new method described as “revolutionary”.

Scientists at Newcastle University have developed a process they say makes them fit better and offer better vision.

Lead researcher and Professor of Tissue Engineering Che Connon said this had “never been seen before”.

Cells grown on a curved rather than flat surface were “crawling over the dome in a lattice-like structure, similar to a pie crust”, he said.

The cells produced “large amounts” of aligned collagen in the same way it is found in a human eye, Prof Connon said.

“There were no easy ways to recreate it in a dish – until now,” he added.

The corneas, which are stronger and more transparent than previous artificial versions, take three months to produce.

The “breakthrough” could solve the shortage of donated human corneas in the UK, Europe and the USA, the university said.

The increase in laser eye surgery, which makes corneas unusable for transplant, has reduced the supply, it added.

The new technique also provides an alternative to plastic corneas, which the body can reject.

It could “revolutionise how artificial tissues are traditionally grown in laboratories around the world”, the university said.

The research, published in the journal Advanced Biosystems, was conducted with scientists from the University of California.

Newcastle University first author Dr Ricardo Martins Gouveia said the research suggested “we will be able to produce corneas that are more similar in shape and form to the natural eye”.

“We think our team will be able to test these in humans within two years.”
