The Do’s and Don’ts of LASIK Eye Surgery

Getting the best result out of your laser eye surgery occurs when you take the necessary steps to prepare for before and after the procedure.   As with any surgery, there are certain risks involved.  This is just one of the reasons it is important that you do everything possible to prevent issues from arising.  Below you will find some basic tips that can help assure you get the best results possible from your LASIK procedure.

Laser Vision Correction Precautionary Steps

Even before LASIK is scheduled there are certain things that you can do to adjust your routine in order to receive the best results from your laser eye surgery.

  • If you wear contact lenses, it is best to stop wearing them for a few weeks leading up to the surgery. Contact lenses distort the shape of the cornea which can cause the results from your LASIK procedure to be less than perfect.
  • Do not use any type of eye drops for at least a week before your laser vision correction surgery.
  • Avoid scents and makeup for a few days leading up to the procedure as well including the day of. The day of it is important not to use creams, lotion, or any other chemical substance near your eyes.
  • Any and all eye conditions that you have previously suffered from are important details to mention to your eye surgeon.
  • Arrange for transportation to and from the surgery. If at all possible, find someone who is willing to stay with you as well.  You will be under the influence of medication for awhile after the surgery and your sight will be off, so driving is not advised.

Post Surgery Recommendations

There are many ways in which to enhance your healing after LASIK.  For the best results post-surgery follow the advice of your eye surgeon and consider the tips below.

  • Hold off on bathing above your neck for the first few days post-op. The last thing that you want to do is to accidentally expose the area to any soaps or chemicals accidentally.
  • Rely on friends and family to drive you until your eyes are fully healed
  • Do not use any types of creams, makeup, face products, or scents near your eyes. Also, wait to modify your hair color for a few weeks after surgery.  Your eyes will be incredibly sensitive, and the chemical scent can literally burn your eyes.
  • Avoid exercise as well. Skip strenuous workouts for at least a week.  Your body needs time to heal after surgery and something as important as your eye sight is not worth risking.
  • Throw out older makeup and start fresh. Makeup harbors bacteria and even though you won’t be wearing it for awhile it is important to not compromise the health of your eyes with an infection.
  • Use protective eye wear especially sunglasses when leaving the house. The sun can damage even the healthiest of eyes.  Unhealed eyes are especially sensitive.  Sunglasses also help to eliminate debris such as sand and other dirt particles from entering your eye.

Eye-opening facts on cataract surgery

 

I REFER to the letter “Laser procedure involves extra cost and time” (The Star, March 6), expressing concerns over the report “Cataract surgery safer with laser” (The Star, March 4). The concerns focused mainly on the writer’s disbelief that Femtosecond Laser Assisted Cataract Surgery (FLACS) is safer or faster than the conventional Phacoemulsification Cataract Surgery (Phaco).

I have been an eye surgeon since the early 1990s. Over the years, I’ve witnessed the emergence of many surgical technologies in Asia including FemtoLASIK, Implantable Contact Lenses (ICL) and various cataract surgery technologies.

Though Phaco would become the standard of cataract practice worldwide after its introduction in 1967, much has changed since then. Phaco involves the surgeon manually creating cuts, openings and breaking the cataract with metal blades and instruments, which was ironically explained to patients as “laser” eye surgery.

FLACS resulted from the success of femtosecond laser technology used in laser eye surgery (Lasik) to create Lasik flaps in 2001. Similarly, when first introduced for Lasik, disbelieving surgeons continued to use blades to make Lasik flaps. Now, however, most Lasik centres use femtosecond laser technology for Lasik procedures, becoming the gold standard for it worldwide.

Approved for use in cataract surgery in 2009, FLACS effectively replaces some key steps performed manually by the surgeon during Phaco. This includes creating corneal incisions, opening the anterior lens capsule (capsulotomy) and dividing the cataract into smaller portions (lens fragmentation). FLACS is also able to correct astigmatism, the major cause of blurred vision.

Emergence of FLACS has changed cataract practice worldwide, allowing the surgeon to perform cataract surgery in a more predictable and precise manner. This increases the likelihood of getting the best outcome and safety, especially with complex cases.

More importantly, most of the procedure is completed before the surgeon even attempts to go into the eye – which is only possible with a laser.

In over 4,000 cases performed in my practice alone, FLACS proved to be highly beneficial for both surgeons and patients and without any significant complications or side effects. FLACS continues to improve alongside technological advancements, shortening the learning curve for surgeons and improving its outcomes.

Many of the reported risks stated in the aforementioned letter were transient (temporary) and mostly resolved now. FLACS incisions are rendered more accurate, predictable and reproducible. Moreover, the new-generation low pulse energy femtosecond laser enables the surgeon to easily open the corneal incision without a surgical blade (hence the term “no-blade cataract surgery”).

Though Phaco may take 15 minutes for experienced surgeons, the majority of cases may be longer, depending on the type of cataract and other factors. A surgeon may require minutes to break a mature cataract into pieces before its removal, but the laser is able to do it within seconds. In our practice, experienced surgeons have averaged around 15 minutes per surgery with FLACS.

In terms of complications and side effects, both FLACS and Phaco share similar incidences. However, FLACS remains a safe procedure for cataract treatment even for glaucoma patients. Prospective and randomised studies show that although there is a rise in intraocular pressure (IOP) when using a vacuum suction cup during FLACS, the effect was transient and well tolerated (not dangerous).

Furthermore, newer FLACS platforms have not only lowered IOP elevation rates but also reduced incidence of eye inflammation after surgery.

Advancement in FLACS technology has also enabled surgeons to create smooth-edged cuts, minimising the risk of radial tears. Additionally, with the liquid immersion interface, incidence of incomplete capsulotomies are eliminated, further reducing the risk of capsulotomy breakages.

With the OCT, capsulotomy has been rendered more precise and centred, resulting in better visual results especially for premium lenses such as multifocals and, more recently, trifocals.

Many clinical studies incorporating advancements in technology, techniques and data in FLACS have emerged to verify the efficacy and benefits outlined above. Scientific literature on FLACS has provided over 250 peer-reviewed articles including randomised controlled trials, cohort studies, case reports and editorials by reputable experts and research bodies. This ensures balance and objectivity in the analyses of FLACS.

This is important as the use of any one study, without taking into account their design and/or sampling methods, may result in potentially misleading impressions and/or conclusions.

For example, the letter quoted the 2016 European Registry of Quality Outcome for Cataract and Refractive Surgery (EUREQUO) study as the largest in the world comparing FLACS and Phaco to date. In truth, this registry-based EUREQUO study compared only 2,814 FLACS eyes and 4,987 Phaco eyes (total of 7,801) and not 20,000 patients as stated.

After an even larger study (9,400 FLACS vs 8,779 Phaco cases), renowned ophthalmic surgeon Dr Thomas Kohnen reported in February 2017 to an international ophthalmology conference that FLACS does have better visual results and overall superior safety profile.

As the number of younger patients increases, expectations of their cataract surgery have also increased significantly. Mostly still working and more knowledgeable, their desire for spectacle-independence, better surgical results and faster recovery drives them to search for better technology and treatments.

While new technology comes with added cost, nonetheless we need to weigh it against the benefits it brings. Furthermore, as with any technology, there will be continuous improvements that render it even more effective and accessible to all.

Though most surgeons in Malaysia still use conventional Phaco, it does not mean they don’t agree that FLACS has its advantages. The major barrier to ultimately accepting FLACS is the high investment in time and money needed to implement it. In a time of evolving technology, it is our responsibility as medical advisers to guide patients with proper, updated and appropriate information to allow them to make informed decisions.

Guidelines To Follow In Order To Qualify For LASIK

Laser eye surgery is performed to help improve a person’s eye sight.  Most LASIK patients are seeking freedom from wearing eye glasses and contact lenses.  If this describes what you are looking for, laser vision correction surgery may just be the best option for you.  While laser eye surgery is effective in correcting the visions issues many Michigan residents are facing, the procedure cannot be performed on everyone.  If you or a loved one are considering laser surgery, it is important to schedule an appointment with a LASIK surgeon to discuss your specific needs.

If you are just beginning to look into this treatment option as an effective method to correct your vision issues there are some general guidelines below to consider.

Considering Age

First it is important to note that laser eye surgery is not performed on candidates under eighteen years of age.  In fact, many eye surgeons prefer that clients be a bit older to undergo the procedure.  As you age your vision tends to change even more.  In order to avoid having to perform LASIK more than once it is best done on candidates whose vision is less likely to change drastically in the coming years.

Health Of Your Eyes

The health of your eyes is another element to consider.  Laser eye surgery is performed to correct eye sight.  To qualify, your eyes must me healthy and free from eye disease, infection, scars, and corneal abnormalities.

Physically Able to Withstand Surgery

As a LASIK patient you are required to lay down.  It is important that you are able to do so without experiencing pain or discomfort.  Vision correction using a laser will be an impossible surgery to undergo if you are unable to lay flat for a period of time without being in pain.

Ability To Focus Your Eyes

Patients undergoing laser vision correction must be able to keep their eyes focused on a single light point for a few minutes.  This helps to guarantee positive results.  With the technology that is used today, lasers have the capacity to keep up with a patient’s eye movement however, the results of those who are able to focus without eye movement often have better results.

Refrain From Using Contacts Before Surgery

Patients must not wear their contact for about a month before the laser eye correction procedure.  This is because, contact lenses affect the shape of the cornea and will in turn affect the results of the eye examination that is done.  For the most accurate eye exam and results, patients must rely solely on their eye glasses for a significant period of time before their surgery.

As with any type of procedure or surgery there is a fair share of risk involved.  With this in mind all patients must sign a consent waiver prior to surgery.  It offers hospitals and medical practitioners protection from legal ramifications if something goes wrong during the procedure.  This is most often NOT the case but is becoming more and more procedural before surgical events.

Call to schedule an appointment with a local eye surgeon today to see if you qualify to undergo LASIK.  Chances are if you are over eighteen, your eyes are healthy, you are able to lay flat for an extended period of time without discomfort, you can live without your contact lenses for a month, and can assume the risks involved you will be a perfect laser eye correction patient.

How Long Does LASIK Last?

If you’ve ever been saddled with eyeglasses so thick that the lenses look like Coke bottles glasses, you’ve probably considered LASIK surgery (laser-assisted in situ keratomileusis, to give it its full name), a fast, safe procedure that began proliferating throughout the United States in the 1990s. In just a few minutes, LASIK can correct eye problems like myopia (nearsightedness — you can only see up close), hyperopia (farsightedness — you can only see far away) and astigmatism (blurred vision). But some patients notice that months or years later their vision seems to worsen again. So how long does LASIK really last?

First, a little on how it works: In a LASIK procedure, a surgeon uses a high-precision blade called a microkeratome or an ultra-fast femtosecond laser to slice a corneal flap into the eye. Then, she lifts the flap to expose the corneal tissue, while an excimer laser reshapes the cornea by removing unwanted tissue. The flap settles back into place and heals within a few weeks. In the meantime, the patient immediately enjoys improved vision.

“The great thing about LASIK is that the results are permanent in the great majority of cases,” emails Eric Donnenfeld, M.D., an ophthalmologist, who has performed many eye surgeries, including LASIK. “Assuming a stable prescription, patients can expect their vision correction to last until age-related visual changes occur – typically after the age of 45 or 50, when most people will need reading glasses.” But, he said, medical conditions associated with aging, such as cataracts, may change vision many years after LASIK.

In a minority of cases, changes within the patient’s eyes – which would likely occur with or without LASIK – cause a reduction in visual acuity (sharpness of vision). This is called myopic regression. Those changes might happen within a year of the operation, or decades later. A quick touch-up procedure (called LASIK enhancement) often restores visual acuity.

There aren’t a lot of studies on myopic regression. Within a year or two of LASIK surgery, maybe 2 percent of patients need an enhancement procedure, according to the American Refractive Surgery Council. After about a decade, perhaps 10 percent of patients will need an enhancement procedure. Eric Donnenfeld notes that “patients with high refractive errors (very thick glasses) have a greater chance of needing an enhancement.”

According to Dr. Chris Blanton, medical monitor and consultant with Johnson & Johnson Vision, if your surgeon is using an advanced procedure called custom LASIK or wavefront LASIK, there’s a 98 percent chance that you’ll need just one procedure, and that’s it. Wavefront technology creates a 3-D image of the eye to use a guide in doing the LASIK surgery.

Touch-ups aren’t risk-free. “Like any surgical procedure there are risks, for example abnormal healing or infection,” says Blanton by email. But only a tiny number of patients encounter complications.

The eyes of younger patients tend to change more over time, and they’re more likely to notice a bit of blurriness as they age, even if they’ve had LASIK. Older patients’ eyes, and the surgical results, are often more stable, with the exception of presbyopia, the decline in close-up vision that naturally occurs with age and forces many middle-aged folks to wear bifocal glasses. Note that presbyopia comes as a result of changes to the lens of the eye, not to the cornea, which is what LASIK operates on.

Doctors say it’s not realistic to expect your laser-focused eyes to remain perfect for the rest of your life. After all, every part of the human body ages and changes, and the eyes are no exception. If you suffer regression after LASIK, and you don’t want to undergo (or pay for) a touch-up procedure, you’re not alone. Many people opt to wear prescription glasses for driving or reading. And of course, whether you’ve had LASIK or not, a yearly eye exam is a good idea to keep your health and your vision at its best.

Improving Eyesight One LASIK Surgery at a Time

There are many solutions when it comes to correcting vision problems.  Some individuals choose to wear contacts and glasses to make their day to day sight better while others investigate more convenient vision correction methods such as laser vision correction including: LASIK, PRK, and LASEK. There are a number of benefits that come with choosing surgery to correct their vision on a more permanent basis.  Although glasses and contacts have been the solution for vision problems since the 1300’s, laser eye surgery offers an innovative approach that allows users proper vision without the use of daily aides.

As with any surgery, the benefits must outweigh the drawbacks or people would not opt to participate as is the case when it comes to laser vision correction surgery.  If patients have specific questions, detailed to their vision situation directly, they should meet with an eye surgeon for a consultation.  Below we will focus on the benefits that most patients receive after correcting their vision with LASIK, LASEK, or PRK.

Improved Eyesight

In studies that have been performed LASIK has proven to be effective, meaning patients have improved vision after the procedure.  For over eighty-five percent of patients 20/20 eyesight returns while over ninety-five percent achieve 20/40.  Irrespective, the results received through laser vision correction surgery are quiet stunning. For most participants an impressive upgrade in vision is had.

Lasting Results

Perfect vision is not obtained instantaneously after LASIK, in fact it may take several months for your vision to adjust to its new normal.  However, once your vision has settled into its new normal the change will be permanent.  Eyesight deterioration from age is possible later down the road but is easily corrected with a follow up surgery.

Quick Recovery

Although you won’t be driving yourself home from the surgery most LASIK patients return to life as normal in as little as twenty-four hours.  Unlike most types of surgery, eye surgery is relatively simple as far as the recovery process is concerned.

Barrier Free Vision

Although there is a cost associated with laser vision surgery, it is far less than the amount of money individuals will spend over a lifetime paying for eye exams, glasses, and contacts.  Each year individuals need to replace glasses and contacts.  This can add up over time not to mention can become quite a hassle if misplaced or broken.  With LASIK you will never have to worry about losing a contact, breaking your glasses or what not.

People started to become aware of the benefits of LASIK around the 80’s with an increase in popularity in the mid 90’s.  LASIK is a common procedure that gives patients the freedom of vision without eyewear.  With this surgery there is no need to be concerned with glasses and contacts and how they will affect spur of the moment plans like swimming.

Remembering the first laser vision correction procedure on its 30th anniversary

Thirty years ago, on March 25, 1988, Marguerite B. McDonald, MD, performed the first laser vision correction procedure on a normal-sighted human eye in Louisiana.

The PRK procedure had been studied in thousands of plastic test plates, both animal and human cadaver eyes, as well as living rabbit and monkey eyes, but had not yet been tested in a living human. However, Alberta Cassady, a 62-year-old woman with cancer of the orbit who needed the eyeball and contents of the eye socket removed, volunteered to allow the team to experiment with the procedure before she lost her eye.

LSU Eye Center used the vivarium at the Delta Primate Center in Covington, Louisiana, and due to the urgent nature of the case, the FDA allowed McDonald to rush Cassady past the monkey cages and perform the surgery on her, according to a press release from Ophthalmic Consultants of Long Island, McDonald’s current practice.

“We watched her heal on a daily basis, right up until the exenteration 11 days later,” McDonald said in an email to Healio.com/OSN. “The refractive and clinical results were excellent, and the pathology report showed the healing pattern that we now know so well.”

The surgery and its postop evaluations went so well that the FDA allowed McDonald and her research team, which included Stephen Trokel, MD, Charles Munnerlyn, PhD, and Stephen Klyce, PhD, to immediately start the blind human trials (blind eyes with normal corneas).

Since that initial surgery, PRK and other laser correction procedures have come a long way, evolving dramatically and becoming popular the world over.

“Looking back on the procedure we performed on Mrs. Cassady so many years ago, I am so proud and excited to see how far laser vision correction has come,” McDonald said in the press release.

Cassady lost her battle to cancer, and despite the fact that research centers are usually named after rich donors, McDonald and her team lobbied for the laser facility at Louisiana State University to be named after her.

“Her remarkable bravery and generosity in the face of such tragedy gave us vital information that allowed the FDA to accelerate the approval process,” McDonald said in the email correspondence. – by Rebecca L. Forand
