LASIK Surgery & Its Benefits:

While some people find wearing glasses inconvenient or feel self-conscious because of their glasses – the reason why most people choose LASIK is that their vision can significantly improve, and they can eliminate their dependence on glasses or contact lenses.

LASIK or Laser-Assisted In-Situ Karatomileusis is a kind of laser eye surgery that corrects astigmatism, near or far-sightedness.

The purpose of the LASIK procedure is to improve the patient’s vision by reshaping the cornea. The cornea is (the clear dome) the clear outer layer of your eye. It is a lens that focuses the light very similar to the lens in a camera.

LASIK reshapes your cornea based on your prescription so that light rays fall into your eye with minimum scatter and optical degradation. The result is greater visual acuity – in other words – the sharpness of your vision is restored.


A life-changing procedure that takes as little as 20 minutes!

Immediate Benefits and Long-Lasting Results

The most important benefit that you will experience is the improvement of your vision almost immediately after the procedure. 20 minutes is all it takes to perform the procedure and the one to two-day recovery time seems insignificant considering the unlimited years of improved vision that you will experience thereafter. There could be a little pain, swelling or discomfort during the healing process but this disappears within a few days.

LASIK achieves stable and long lasting results for almost all patients – although very few can experience an ever so slight change in their vision over the years.


Those of you who juggle one or multiple pairs of glasses, continuously misplace their glasses, experience discomfort and headaches because of heavy glasses and frames, or are tired of handling and cleaning glasses and contact lenses can look forward to being able to be active again without limitations.

LASIK impacts activities like swimming or playing sports (especially contact sports). You don’t need to tone down your performance, guesstimate distances or fear that your contact lenses are simply washed away.

Some of you might be feeling self-conscious or less confident because of your glasses. LASIK can improve your appearance and comfort. It lets people see your face without frames and thick lenses.

While LASIK can appear pricy, over the years, your investment will be smaller compared to ongoing costs of glasses and contact lenses.

Who Should Perform LASIK?

Cornea specialist

LASIK is performed on the part of the eye called the cornea. A fellowship-trained cornea specialist is most suitable for performing this procedure safely and accurately.
Please note that some ophthalmologists may claim that they are cornea specialists but are not fellowship-trained. Ask this question: “Do you perform corneal transplants?” only a true cornea specialist does.


The Screening Exam

A critical step!

The screening exam is an extremely important part of the LASIK process. keep in mind that LASIK is one of many available options for vision correction. The purpose of our comprehensive screening exam is to answer the following questions:

01What is the procedure that will give me the best vision in the safest manner?

02Am I a good candidate for LASIK?

03What type of LASIK is best for me?

04What can I expect after LASIK?

How is LASIK Performed?

LASIK is a relatively quick and simple outpatient procedure that is entirely pain free. Here’s an overview of the individual steps:



Preparing the eye for surgery. Dr. Cohen will use eye drops that numb your eyes completely. You won’t be feeling any pain. Then we will make you comfortable in a lying position.

Creating the flap

The next step is to create a flap in the cornea. In order to achieve maximum safety and accuracy. We use two different lasers. The first laser creates the flap.

Reshaping the cornea

The following step performs the corrective treatment with a second laser. This whole treatment is done without any blades.

Closing the flap

When the cornea has been corrected, Dr. Cohen replaces the flap and smoothens it into place. It will adhere to your eye naturally and without stitches.


You rest for 15 minutes and can then return home. It is important that you follow all post-operative instructions issued by Dr. Cohen and his team.

Choosing the Right Surgeon.

For the last 20 years, Dr. Cohen has helped tens of thousands of patients achieve their best vision. A fellowship-trained cornea specialist like Dr. Cohen is most suitable for performing this procedure safely and accurately. And while some ophthalmologists may claim that they are cornea specialists, they are not fellowship-trained and it is important that you do your research and choose a qualified and experienced professional.

A trustworthy and experienceD cornea specialist performs a thorough screening exam as this is an extremely important part of the LASIK process.

You should research the following details:

Which Option is Best for Me?

Considering that there are many available options for vision correction, your cornea specialist should always recommend the option that is best for you even if that is not LASIK. Dr. Cohen’s comprehensive screening exam leads to answering the following questions:

01What is the procedure that will give me the best vision in the safest manner?

02Am I a good candidate for LASIK?

03What type of LASIK is best for me?

04What can I expect after LASIK?

Be confident about your choice

It is natural to be somewhat apprehensive about an elective procedure that involves your most important and sensitive structures – your eyes. That is why we will take you through a thorough screening exam and will lay out realistic expectations for you.

Rather than letting fear and worry prevent you from experiencing a lifetime of better and more comfortable vision, our staff and doctors will provide you with all the information you need to make an informed decision that allows you to go into the surgery as confidently as possible.

Should you not be a perfect LASIK candidate, then we will explore other options. These may include LASIK alternatives or not having surgery at all.


All-Laser or Bladeless LASIK

All laser LASIK means that the whole LASIK process is done purely with laser and without the use of any blades for the flap formation. All-Laser LASIK is believed to be safer than old fashion LASIK and is the standard practice in the Cohen Eye Institute.

Each of us have imperfections in our eyes that contribute to the degradation of the image quality that our eyes can see. That is believed to be the main reason that most eyes are limited to 20/20 vision.

Contoura® is a type of topography-guided LASIK that is aimed at visual results that could be better than 20/20. 

Prior to the LASIK procedure, the Contoura Topolyzer device first obtains a fingerprint-like image of the cornea. It then maps irregularities present on the cornea to each specific fine point on the cornea.


This map is then imported into the LASIK treatment device which converts the map into a specific treatment for each unique fine point on the patient’s cornea.

This is different to traditional LASIK, which treats the eye based on a prescription measurement alone. This point-to-point map data along with the patient’s prescription produces visual results that are significantly more accurate than the prescription data alone. In fact, topography-guided treatments are often used to improve vision in patients that have visual limitations due to problems like corneal scarring, irregular astigmatism, and other eye issues where solutions like glasses are ineffective.

Multicenter clinical trials show that other than just the visual acuity, Contoura® improved the quality of vision in patients. This means that not only the sharpness improved but there were fewer complaints of visual symptoms compared with glasses or contacts. In this study, 64.8% of patients achieved visions of 20/16 or 20/12.5 (the lesser the denominator the better the vision. For example, 20/12.5 is 60% sharper than 20/20).

PRK is a different type of laser eye surgery. It doesn’t create a flap in the cornea, but instead removes the surface cells of the cornea.The laser is then used to reshape the cornea to correct the vision problem.


What are the
Alternatives to LASIK?


As shown above. PRK is a LASIK alternative that can correct your vision without creating a corneal flap.

Refractive Lens Exchange

Also called lens replacement surgery. It is similar to cataract surgery and the natural lens of the eye is replaced with an artificial lens


or Small Incision Lenticule Extraction – a procedure that reshapes the cornea through the creation and removal of a piece of tissue (lenticule) within the cornea


or EVO Visian Implantable Collamer® Lens – This is a flexible lens that is implanted in the eye to correct vision

The Fear Factor:

It is natural to be somewhat apprehensive about an elective procedure that involves sensitive structures like your eyes. However, you want to avoid fear, robbing you of a lifetime of better and more comfortable vision. At the CEI, we will take the time to do a thorough screening exam and will lay out realistic expectations for you. We are certain that our staff and doctors will make you extremely comfortable with your decision. If you are not a LASIK candidate we will explore other options. These may include LASIK alternatives or not having surgery at all.

Is the LASIK procedure painful?

During LASIK eye drops are used that numb the eyes. So you won’t be feeling any pain.

During the screening exam, Dr. Cohen will thoroughly examine you and recommend the best solution for you.

Why Lose Precious Time & Suffer with Less than Optimal Vision?

Lasik surgery can help anyone see better

LASIK after 45 Years of Age - Presbyopia

Although LASIK can provide excellent distance vision at any age. After the age of 45, reading and close-focus activities become more difficult. LASIK can solve this near vision problem for most people by using a method called mono-vision.
Monovision allows proper functioning of the eyes for both near and distance. However, it has certain limitations and is not suitable for everyone. Some people may find that a different procedure called Clear Lens Exchange, may be a more appropriate procedure for them.

Managing the Risks

Saving money through cutting corners doesn’t serve you

Your eyesight is invaluable. It enriches your life in innumerable ways and gives you freedoms that you don’t want to miss out on. And because eyesight is such a precious possession, private equities and other corporate entities have started to take notice of LASIK. Not necessarily with the health of the patient in mind but instead with a keen intent of maximising profit.

In the New York and New Jersey area alone, many of these corporations have purchased or set up practices with the intent of maximising profit through reducing costs and winning market share. But not while being led by ethical patient care principles but rather by false efficiency and cutting costs and corners such as:

The Results of Cutting Corners

The results are increased risks that include flap complications during the surgery, infection, scarring, and what’s known as ectasia – glare and haloes at night. Stories that talk about complications like that can be found aplenty.

What is important to realize is that many of these complications could have been avoided if a more thorough screening exam was performed prior to surgery or if a more thorough surgical procedure was followed by a conscientious and skilled surgeon.

Dr. Cohen adheres to one of the strictest criteria for LASIK patient selection. These criteria were formed and refined during his over 20 years of surgical experience.

In addition, he performs a wide variety of vision correction procedures so that he can tailor the approach and procedure that you need to achieve the best possible vision in the safest fashion.

Can I Afford LASIK Surgery?

It is tempting to say: “How can you not afford LASIK surgery?” Considering that it is a procedure that you undergo once in your lifetime, and that this procedure improves your quality of life on many accounts – it makes sense to consider this procedure an investment rather than a costs. And you have the choice to influence the return of that investment by choosing the best and safest option for you.

Costs for LASIK in the New York area can vary widely and sit between $1,500 - $4,000 per eye.

Factors that you need to consider when selecting your surgeon are:

The fact that Dr. Cohen has hundreds of international visitors each year that come for their LASIK to New York, speaks volumes.
