Conventional LASIK vs. iLASIK

Vision correction has come so far from the first eye glasses introduced in the 13th century, we have evolved from specs to surgeries. The first Laser Vision correction surgeries started with PRK in early 1990’s, followed by the LASIK procedure late 1990’s and then iLASIK in the early-mid 2000’s. If you are interested in LASIK eye surgery and have come this far, you’ve likely been doing some research on Blade vs. Bladeless. What do these terms really mean? What are the advantages and disadvantages? Is it worth it? We want to clear the air and answer some of these common concerns.

LASIK 101

Let’s start by telling you what happens during the LASIK procedure, this will help you understand the difference! During LASIK, the cornea (the outermost layer of the eye) is reshaped to correct vision including nearsightedness, farsightedness, and astigmatism. In order to get to the corneal tissue that needs to be reshaped, the LASIK surgeon must create a thin corneal flap. The flap is the very exterior layer, often described as thin as “saran wrap” or “skin on an onion”. The flap is then lifted for application of laser energy that reshapes the eye for vision correction. The flap stays connected to the eye, when the LASIK procedure is complete and the cornea has been reshaped, the surgeon “closes” the flap, which naturally starts to ahere right away.

What is Conventional or traditional LASIK?

In a conventional LASIK procedure, the surgeon will use a bladed instrument known as a microkeratome to cut a thin flap into the cornea. The hand-held blade comes in direct contact with the cornea in this type of procedure. The flap (door into the cornea) created by a microkeratome is not always precise and may be thinner toward the middle of the flap because of how the blade works. This has the potential to cause certain types of flap defects including buttonholes (where the flap is shaped like a button) and flaps that become detached from the eye or incomplete.

What does “Blade-Free” LASIK means?

In a 100% blade-free LASIK procedure (AKA bladeless or all-laser LASIK procedure), the surgeon will use the advanced technology of a laser to create the flap (door to the cornea). At Bense Vision, our iLASIK procedure exclusively uses the advanced IntraLase iFS™ femtosecond laser – the most advanced Laser Vision Correction used worldwide. This laser uses high-energy laser pulses to separate the corneal tissue. Using this advanced laser technology to create the corneal flap means a more consistent thickness throughout the flap and reduces the number of complications that can result from using the bladed microkertome instrument.

What are the advantages of blade-free flaps

It is a fact that iLASIK technology is 25 times more accurate that conventional LASIK. It is so custom, so precise, and so accurate that we are able to treat many more patients, those that would not have been candidates for “conventional” LASIK are more likely to be good candidates for iLASIK today. As well, using a laser to create the corneal flap during LASIK will lead to fewer flap complications, that we used to see when doing cornea bladed LASIK. This can translate to additional benefits in terms of long-term quality of vision following this iLASIK procedure. Numerous studies have demonstrated the benefits of using a laser to create the corneal flap in a LASIK procedure. Some of the advantages compared with conventional LASIK include:

  • Less flap complications
  • Increased accuracy creating the corneal flap
  • Unprecedented control and precision during the procedure
  • Less patient anxiety without the “blade”
  • Reduced occurrence of halos and glare associated with blade
  • Better long-term vision quality
  • Treat more patients
  • Dry eyes more associated with blade

Is Blade-Free really worth It?

There are many advantages to blade-free LASIK, and there are certainly associated costs with this type of procedure. However, at Bense Vision we believe so strongly that the blade free iLASIK procedure, is the standard of care for today – we do not pass on that cost difference to our patients. It is our opinion that patients who receive the bladed LASIK for the same cost as Bense Vision’s iLASIK are simply overpaying. Did you know? The blade-free iLASIK procedure is the only approved laser vision correction procedure for use by NASA and US Military branches! Now that you understand the advantages compared with conventional LASIK, it’s up to you to determine if the benefits are important to you! When it comes to your vision, you decide what you want and deserve!

Don’t underestimate Surgeon Experience!

While blade-free iLASIK offers many benefits compared with conventional LASIK, the most important aspect is that the patient is in the hands of an expert surgeon. We are talking about tools, and tools are only as good as the surgeon who is using them. For example, a novice surgeon does not have the experience and skill as a seasoned surgeon who has been performing LASIK for many years. While both of these surgeons may use the same femtosecond laser, the seasoned surgeon would be more skilled at using the laser to provide patients with optimal vision outcomes. So don’t let the appeal of blade-free LASIK technology blind you to other important LASIK considerations, such as surgeon experience. We believe in the best, that is why we practice exclusively blade free for our LASIK patients – we are the only iLASIK certified provider in the province.

Experience Blade-Free LASIK from the Best!

At Bense vision you will receive 100% blade-free iLASIK technology in the hands of an experienced and skilled iLASIK surgeon who has performed almost 30,000 laser vision correction surgeries! Because we remain committed to using leading-edge technology and being Newfoundland’s most experienced and qualified iLASIK surgeon, we have helped 95% of our iLASIK patients see 20/20 or better following their procedure, with the majority seeing even better than that….20/15! At Bense Vision we are a “true centre of excellence” for LASIK eye surgery in the province.

Life after LASIK

Posted on by Maria Afonso in Bense, Bense Vision, Eyes, iLASIK Leave a comment

You can begin enjoying the advantages of LASIK immediately after the procedure! The recovery process is so quick that, if your workplace has a low risk of eye injury, you can return to work one day after getting LASIK. Before you can enjoy your new eyes, it’s important to follow the doctor’s instructions and be aware of what you can and cannot do.

Immediately After LASIK Surgery

After your surgery, it is important to do whatever you can to protect your eyes. Your doctor will provide you with sunglasses or eye shields, which you will have to wear while sleeping. You will also be given eye drops to prevent inflammation, infections and to keep your eyes moist during the healing process.
It is crucial that you have transportation arranged for after your surgery, as you will not be able to drive immediately after the procedure has been completed. Once you’re home, you may feel like scratching and rubbing your eyes, but it is very important that you do not touch your eyes during recovery time at all. After your procedure, your corneal flap is healing, and rubbing your eyes can halt the healing process by displacing the flap. You may also experience red, watery eyes during healing, but these are all normal, temporary symptoms and nothing to be worried about!

The Next Few Days After LASIK

Your doctor will likely want to do a check-up within the first 24 hours of your procedure to make sure your eyes are recovering well. This is when you will be advised as to when you can drive, and if it’s safe to return to work. After 3 days, you may be able to resume regular outdoor activities, if you are wearing protective eye gear and are being very careful.
You can also resume applying make-up at this time, as long as you stay away from your eyes. This means no mascara or eyeliner just yet, ladies! Additionally, when washing your face make-up off, don’t forget to stay away from the eyes, which can be done by using make up wipes instead of a full-face wash. This alternative will help prevent you from being tempted to rub your eyes during make up removal.

One Month After LASIK

In the weeks following your procedure, you may feel as though there is something in your eye at times, but this is just a normal side effect of LASIK. As long as you are not touching or picking your eyes, this symptom should go away in due time. At this time, you can now resume wearing make-up, and play your favourite sports without eyewear protection!

A Few Months After LASIK

You’re free! A few months after your procedure, you can finally enjoy your new eyes without any restrictions at all. Of course, we always recommend wearing sunglasses and eye protection for high trauma activities, such as outdoor sports, or exposure to the sun. Now go ahead, and savor a life without glasses and contacts!

The Value in Seeing Clearly: 3 Benefits of LASIK

Posted on by Maria Afonso in Bense, Eyes, Vision Leave a comment

Quick, safe, and effective, LASIK has become one of the most popular methods in treating common eye conditions. If you are nearsighted, farsighted, have an astigmatism or glaucoma, LASIK might be for you! Here are 3 reasons why you should consider LASIK to permanently correct your vision:

Benefits of LASIK

  1. Glasses and Contact Lenses

If you have glasses or contact lenses then you know all too well that they can be a hassle. From itchy, red, irritated eyes to random blurs in vision, contact lenses can be quite uncomfortable. In addition they require routine cleaning and maintenance which, if you’re not an avid cleaner, can increase your risk of bacterial eye infections. In addition, remembering to take them out every night can be a real pain in the neck when you’re about fall asleep. Why not make your life easier by dropping the rules and responsibility of having contacts and get LASIK! With LASIK you can also forget about the frustration of losing or even breaking your glasses.

 

2.   Cost of Contact Lenses

The lifetime costs of contact lenses can be significantly more than the one time procedure required for LASIK (depending on factors such as your age and the type of lenses you require). Just think about the number of boxes of contact lenses you purchase a year. Bense Vision’s price match guarantee means if you spot a lower price advertised for LASIK, we’ll match it!

 

3.   Seeing Clearly

Did you know that over an average lifespan you see close to 24 million images. Don’t you want to see the world around you with the sharpest vision? In most cases, vision can be restored to 20/20 with LASIK. What could be more perfect than perfect vision! With the Bense Lifetime Satisfaction Plan if we are unable to correct your vision to 20/20 the first time, we offer free enhancements for life if you meet the requirements of the plan. Eligibility for the plan can be determined at your initial free consultation.

Bense Vision uses the new HD Analyzer Optical Quality Analysis (OQAS) System for Refractive Surgery Screening

Posted on by Maria Afonso in Bense Leave a comment

1236883_570052123059372_863987095_nSt. John’s, Canada, 14th October 2013

Bense Vision has announced the use of the next generation of the Optical Quality Analysis System, the HD Analyzer, following the system becoming available in North America and after recent issuance of the European CE mark for the system.

The HD Analyzer is a unique diagnostic system that allows for an objective analysis of optical quality in a persons eye. The system provides an objective measure of ‘light scatter’, which is caused by a host of ocular factors including corneal disease or imperfections on the ocular surface as well as cataract formation, which can lead to degradation in retinal image quality. Light scatter is not measurable using traditional wavefront aberrometry techniques such as the WaveScan measurements and presents a diagnostic challenge that only the HD Analyzer is now able to answer.

An objective Analysis

This latest generation Optical Quality Analysis System, the HD Analyzer Optical Quality Analysis System (OQAS), is based on the double-pass technique and provides an objective measurement of the quality of the retinal image, including higher-order aberrations and scattered light.1,2 When scatter is present, the quality of the retinal image is degraded.3 The higher the OSI, the worse the patient’s quality of vision (retinal image quality).

Unique Technology

Employing double-pass retinal imaging, the HD Analyzer uses a near infrared light source that is imaged on the retina. The size and shape of the light are analyzed by the system in order to determine the higher order aberrations present as well as scattered light. The system provides ophthalmologists and optometrists with a Point Spread Function (PSF), Objective Scattering Index (OSI), as well as the derived Modulation Transfer Function (MTF) and its cutoff.

The HD Analyzer has been well received by US ophthalmologists. The HD Analyzer gives ophthalmologists the ability to go beyond traditional subjective means of vision assessment, which is increasingly important in today’s ophthalmology practice.

The HD Analyzer OQAS is versatile and can be used for:

 v Diagnosing and monitoring the evolution over time of ocular pathologies such as an unstable tear film in dry eye situations or of refractive disorders.

v Evaluation of the level of ‘objective light scatter’ (OSI) for the early detection of a cataract and the determination of its effect on retinal imagery.

v Optometric or ophthalmic screening of refractive patients: the OSI is an invaluable tool to predict if a good visual outcome is likely. (see below)

v Comparing pre and post-cataract and refractive surgery measurements.

v Precise measurement of MTF (Modulation Transfer Function), which is often overestimated by WaveScan aberrometers when scattering exists, as in cataract patients.

v Evaluation of tear film quality.

v Objective measurement of the amplitude of accommodation and pseudo-accommodation in IOL patients.

v Objective assessments of the pre and post-KAMRA insert client. (Corneal Vertex, P1 Image, Angle Kappa, Inlay placement and more).

A Unique Approach to Selecting Patients for Refractive Surgery including KAMRA Vision clients

 We use this unit as a diagnostic device that measures light scatter, which allows optometrists and ophthalmologists to identify the origin of patients’ visual problems. We measure the position and direction of the client’s Corneal Vertex and Pupil Centre in order to establish the 1st Purkinje Image that will guide surgeons as to best centration spot for a KAMRA Vision Inlay.

Obtaining images with the HD Analyzer is easy and straightforward. Most traditional measurements of visual quality are subjective. The HD Analyzer, in comparison, objectively measures the quality of the retinal image and provides eye doctors with an understanding of what the patient likely sees. This analysis quickly identifies whether the visual problem is ocular or neurologic in origin and allows eye practitioners to know the limits of the patient’s current vision.4

Diagnostic Value

New patients who come to Bense Vision for a candidacy evaluation for refractive surgery, all undergo testing with the HD Analyzer. Patients who wear contact lenses or glasses are tested while wearing them. Those who meet the traditional requirements for refractive surgery and who have an OSI of less than 2 are generally considered good candidates as far as retinal image quality is concerned. An OSI higher than 2 indicates significant optical scatter advocating caution.

We do not recommend laser vision correction if the origin of the scatter (>2) is due to cataract formation. If poor tear quality or a decreased tear volume is the cause,  we treat the problem accordingly and reassess the OSI in 2-4 weeks time.

Patients who are good candidates objectively still go through the consultation process. Knowing what level of vision patients are starting from, helps us to set appropriate expectations for the client. If their expectations are reasonable, we proceed with treatment.

To date, the most valuable use of the HD Analyzer at Bense Vision has been for patients who achieved good results with refractive surgery (LASIK/PRK) initially the 1st time around, but who are now experiencing a decline in their vision and seek further enhancement or touch-up surgery. They may have an acceptable 20/20 or 20/25+ corrected DVA in an examining lane, but still show a significantly increased OSI (for example >2). If the tear film and tear volume are satisfactory, the optical scatter is likely due to cataract formation. Here we recommend against further laser treatment and suggest considering cataract extraction if appropriate.

Improved patient outcomes

Patients enjoy seeing their HD score pre-operatively as well as the simulation of their retinal image. In our experience, the HD Analyzer has improved the selection of patients for refractive surgery and the consultation process. Knowing the optical limits of a clients’ vision is important in making the appropriate choice for their needs.

To summarize: Performing refractive surgery on individuals with significant light scatter (OSI) in hopes of correcting their visual problems will often lead to their disappointment. Our early experience with the HD Analyzer has been positive and has given us more confidence in selecting patients who could benefit from an initial or repeat laser treatment.

NEWS: Bense Vision obtains an iDesign® Advanced WaveScan Studio Aberrometer, the world’s most advanced diagnostic LASIK tool.

Posted on by Bense in Bense 4 Comments

abbott-idesign-1

St. John’s, NL, Canada

Bense Vision announced today it has obtained one of only a handful of iDesign® Advanced WaveScan Studio aberrometers available in North America. iDesign is the industry’s most advanced, high-definition measurement device for Custom LASIK (Wavefront-guided LASIK) procedures and is a next-generation diagnostic tool for mapping and analyzing corneal aberrations in the eye for wavefront-guided LASIK procedures.

The iDesign system measurement makes an individual “blueprint” of the eyes, mapping the imperfections and creating a treatment plan. Once a corneal flap is created using the iFS Femtosecond laser (the only such laser in Atlantic Canada is at Bense Vision), this iDesign treatment plan is then executed using the STAR S4 IR Excimer Laser system for a computer-driven custom laser correction, unique to each patient.

“The use of the iDesign Advanced WaveScan Studio, further enhances the three-step iLASIK process to set a new standard for laser vision correction in Canada,” said Mike Bense MD, president Bense Vision.

Dr. Mike Bense: “Since the introduction of our iLASIK technologies to St. John’s several years ago, we have remained the only LASIK provider in this region to offer iLASIK in Eastern Canada and organizations with the highest standards for safety and visual acuity, including the U.S. Military and NASA, have embraced iLASIK for their most elite personnel, including sharpshooters, fighter pilots and astronauts because of our exclusive, validated safety and precision performance. No other LASIK provider in Atlantic Canada including St. John’s, provides this advanced state-of-the-art LASIK technology”

The iDesign benefits include:

• More accurate, customized corneal and wavefront measurements

• Five diagnostic ocular measurements within a single capture sequence that

determine the eye’s refractive error, wavefront error, corneal topography and

corneal curvature, as well as pupil size

• The iDesign aberrometer represents a new and exciting technology that allows patients with highly blurred or distorted vision, the benefits of a truly customized, wavefront guided LASIK procedure

Dr. Mike Bense: “We are extremely pleased with the acquisition of the iDesign aberrometer, because we know that patients, treated in clinical studies where it was used to map their eyes, were some of the most satisfied patients they had seen to date, according to Prof. Bruce Jackson, M.D. clinical investigator, University of Ottawa Eye Institute”.


Bargain LASIK Fees: Are they for real?

Posted on by Bense in Bense 37 Comments

Believe it or not, about a 1/3rd of North American LASIK centres, and especially discount LASIK centres, still use a metal blade instead of a laser to create the LASIK flap, despite the fact that blade-free Femtosecond laser technology has been shown to be much safer, more predictable, and can achieve superior outcomes.

Dr. Bense is the only centre in Atlantic Canada that has an iFS Femtosecond laser (for the past several years). We have totally abandoned the use of outdated steel blades in all our LASIK surgeries several years ago despite the fact that Dr. Bense introduced bladed LASIK to Eastern Canada over a decade ago.

So, why would any laser centre today still offer this outdated blade technology that has been shown not to be as safe as blade-free technology? The answer should be obvious: cost. The price of a new Femtosecond laser exceeds $400,000, which does not include an annual maintenance fee of over $60,000. A new microkeratome that carries a steel blade used in discount LASIK surgery, costs less than $40,000, and there are no annual maintenance fees. A steel blade is around $50 and is used for cutting the flap in both eyes. This explains the magic of using cheaper technology that allows for significant savings to a laser centre, which offers this outdated technology with a microkeratome.

At Bense Vision, we acquired the first very latest, 5th generation blade-free IFS laser in Eastern Canada, which has a much faster (2.5X) speed of speed of 150 KHz. In addition, the new iFS technology can create a tailored flap of almost any configuration, which leads to a more stable flap position.

Our new iFS laser, is likewise used in our advanced KAMRA Corneal Insert procedure, which can replace reading glasses as well as in the FSAK procedure that gets rid of astigmatism in many situations.

Despite using cheaper technology, we have discovered that bladed LASIK procedures offered at some discount LASIK centres are priced but an average of only $100 – $200 cheaper than our safer and more advanced iFS blade-free iLASIK procedure.

So, are those ‘low’ advertised prices for real? Go find out for yourself.


LASIK/PRK Xtra™ Surgery now available in St. John’s and Eastern Canada

Posted on by Bense in Bense 9 Comments

We are pleased to announce that Bense Vision is the first centre in Atlantic Canada to offer LASIK/PRK Xtra™ Surgery with the corneal crosslinking system from Avedro®. Internationally this revolutionary technology has shown a remarkable efficiency in reducing the risk of developing secondary keratoconus or corneal ectasia after refractive eye surgery in selected patients, and an enhanced precision and outcomes for many refractive errors like hyperopia, high myopia, high astigmatism cases, and in patients previously thought to be poor candidates for refractive eye surgery.

Although Traditional LASIK or PRK Surgery is considered to be one of the safest and most successful procedures performed in medicine today, there are definite risks involved with these surgeries. Important examples applicable to this discussion include the development of corneal ectasia (a type of keratoconus) one to two years following surgery, and regression of treatment effect in many cases especially in hyperopia and high myopia patients.

Although some of the steps are still performed manually with a steel blade (microkeratome) by about 30% of North American surgeons, the majority of surgeons have now abandoned the use of this outdated technology and have now adopted the use of blade-free Femtosecond Laser technology instead. Despite these advancements, there remains a certain percentage of patients that are not ‘suited for surgery’ because of thinner corneas, abnormal topographic assessments, and other outliers or are at a higher risk of developing the two above-named coplications.

This is where LASIK or PRK Xtra™ is totally and undeniably of great use. By adding a simple 2- minute painless procedure to the standard LASIK or PRK procedure, Bense Vision can virtually guarantee a profoundly better and safer outcome in the type of patient we recommend to undergo the Xtra™ procedure. The procedure involves saturating the corneal stroma beneath the flap with Riboflavin (Vitamin B2) for about a minute then irradiating the stroma with UV light after the flap has been replaced for a minute or two.

The Avedro System is the only such system in St. John’s and can now automate many of these steps, adding a greater amount of precision to the entire crosslinking procedure and potentially make surgery even safer and more predictable.

A reproducible precise procedure, improves the predictability of the final visual and refractive outcome. This procedure may allow ophthalmologists to meet the demands of a certain segment of their refractive patient base that desire a safer LASIK or PRK procedure, and to obtain the same results that have been accomplished with other laser vision correction procedures.

All patients that are seen at Bense Vision who meet the recommended criteria will be offered this new technology. If they decline this treatment option, the Traditional Blade-free LASIK/PRK options are still available if no contra-indication exists. The fee is $500 per eye in addition to the LASIK or PRK procedure fee.


Bense Vision offering KAMRA™ Corneal Inserts in St. John’s

Posted on by Bense in Bense 1 Comment

images1The most significant advance in presbyopia surgery in the past 100 years has been the development of the KAMRA™ Corneal Insert. We are proud to be one of the first centres in Canada to offer this incredible surgery with the AcuFocus™ presbyopia system. This system utilizes the small-aperture technology used in the KAMRA™ inlay. This is a very simple yet elegant approach to improve ones near vision whilst not affecting the distance vision in a significant way.

Using the AcuTarget Diagnostic Unit (ADU) to precisely measure the position and direction of the pupil centre and the corneal vertex (coaxial viewed light reflex) which is needed to accurately centre the corneal implant enhances the precision of the system. It automates many of the steps that were previously performed manually with a direct ophthalmoscope or the use of non-coaxial excimers. The precision of the laser allows for enhanced safety and excellent visual outcomes.

The AcuFocus KAMRA Corneal Insert® has a number of unique advantages over traditional presbyopia Surgery:

  1. No intraocularinvolvement
  2. Avoiding many of the traditional side-effects seen with LASIK and PRK
  3. Lower risk of infection
  4. Adjustable (centration) and removable
  5. Can be combined with other refractive surgeries or procedures
  6. Potential for clearer vision early postoperatively with very little adverse effect on ones distance vision
  7. No further adjustments needed with further aging

The AcuFocus KAMRA Insert is a revolutionary presbyopia treatment that is safe and precise. The advent of this technology has made it possible for more patients to seek treatment and obtain simultaneous clear near and far vision, including patients with astigmatism.

This technology can be applied to people who:

  • Have had previous cataract surgery and now need reading glasses
  • Have had previous LASIK/PRK surgery and now need reading glasses
  • Simply need reading glasses at age 40 years or beyond

To learn more about the KAMRA Insert surgery in St. John’s, contact Mike Bense, EyeMD at Bense Vision to schedule a complimentary comprehensive consultation.
