With so many options available for LASIK laser vision correction in Manhattan and across New York, New Jersey and Connecticut, coming to a decision regarding your treatment can be a confusing experience. You may have heard various terms and phrases, whether from friends or in the media, that have left you feeling quite baffled. What are the differences between LASIK, LASEK, Intacs®, PRK, surface laser, intracorneal implants, phakic implants, clear lens extraction and conductive keratoplasty? Which technology is best for me; iDesign®, Wavefront®, CustomVue®, IntraLase®, bladed or bladeless technology, excimer laser, topography, pachymetry or Pentacam? It is an alphabet soup of choices!

Your Laser Eye Surgeon
Let’s start off this explanation of LASIK laser eye surgery with a metaphor. Imagine your LASIK surgeon as a master carpenter. A master carpenter who does not use the best tools will get suboptimal results. Similarly, a merely average carpenter, even when using the best tools, will also get suboptimal results. That said, the quality of your results will depend heavily on which doctor you choose to perform your laser eye surgery. Some patients mistakenly think that anyone with top-notch equipment can achieve a superior outcome. Laser eye surgery, the most popular form of which is LASIK surgery, is a surgeon-dependent procedure. No amount of high-tech equipment can replace a skilled surgeon. So, choose your surgeon carefully. A good surgeon will spend time with you during your evaluation, get to know you and your individual visual needs, answer all of your questions and address any concerns you may have, in addition to providing you with a detailed guide to your post-operative care.

New Technology in Laser Eye Surgery
Now, let’s move on to the laser eye surgery technology used in our New York LASIK location, serving New York, New Jersey and Connecticut.
LASIK is the most commonly performed procedure for laser vision correction. It can correct visual errors in the vast majority of farsighted, nearsighted, and astigmatic patients. First, our iDesign® Refractive Studio is utilized to obtain the most accurate pre-surgical measurements. Then, during laser eye surgery, a paper-thin flap in the cornea is created using the femstosecond IntraLase laser to give a custom-designed laser access to the corneal tissue underneath. The laser that is used is an excimer laser, which Dr. Mandel began researching at Columbia in 1984, more than a decade before it received approval from the FDA for use in human treatment. The replacement of the flap after the laser treatment allows for a fast recovery. In fact, the day after their laser eye surgery, most patients are able to return to work or even exercise. It is not just the laser, but the longstanding technique that makes LASIK so popular.
As with LASIK, the iDesign® Refractive Studio is utilized to obtain the most accurate pre-surgical measurements. Then the same excimer laser used to correct vision in LASIK is used for PRK. Unlike LASIK, PRK does not involve the creation of a flap in the cornea. In both LASIK and PRK, Dr. Mandel reshapes the tissue beneath the epithelium, the very thin top layer of the cornea. In PRK, the epithelium is removed. Because the epithelium is affected, the healing time is longer with PRK than with LASIK. Patients need to wear a bandage contact lens for one week following the laser eye surgery, during which time the vision is somewhat blurred. In addition, after the surgery, steroid eye drops are used for longer than with LASIK, and Vitamin C tablets are taken for six months.

Frequently Asked Questions about Laser Eye Surgery
Why would someone have PRK when quicker and more comfortable results can be achieved with LASIK?
Patients with thinner corneas and those in occupations in which they have a higher chance of sustaining eye trauma are usually better candidates for a surface laser procedure, like PRK, rather than LASIK. For example, when Dr. Mandel consults with patients about laser eye surgery at his New York offices, also serving New Jersey and Connecticut, he often recommends PRK surgery for those in the armed services and law enforcement, as well as those engaged in contact sports like kick boxing.

I want the best technology in laser eye surgery; are custom treatments with the iDesign Regractive Studio the way to go?
The iDesign Refractive Studio is the latest generation in customized LASIK treatments. Mandel Vision is proud to be the first and only practice in New York to offer this state-of-the-art technology to our LASIK patients. This technology uses a proprietary INSIDE+OUT approach that combines both corneal topography measurements and wavefront analysis.

How do I know if I am a good candidate for laser eye surgery?
Combining two screening technologies, called topography and tomography, with a comprehensive eye exam enables us to determine your candidacy for laser eye surgery. Topography is a two-dimensional representation of the three-dimensional contour of a cornea. Tomography is a measurement of the thickness of a cornea. Mandel Vision uses advanced Pentacam technology to measure the corneal thickness. When patients from Manhattan and across New York, New Jersey and Connecticut come to our office for a consultation to determine their candidacy for laser eye surgery, we take both their eye exam and information about their lifestyle into consideration.
What is the difference between bladeless and bladed laser eye surgeries?
While it is a common misconception among patients that the bladeless laser technique does not involve the creation of a flap, both bladeless and bladed laser eye surgery requires the creation of a corneal flap that is reproducible in both diameter and thickness. During bladed laser eye surgery, the flap is created with a microkeratome, a precise microscopic blade oscillating at a very high rate. With bladeless surgery, the flap is created using a special laser. The laser that creates the flap is different from the laser that corrects your prescription. The laser used to create the flap is a femtosecond laser, called the IntraLase® laser, and the laser that corrects your prescription is an excimer laser. The femtosecond technology has evolved considerably over the past two years.
What if I am not a candidate for these laser eye surgery procedures, are there other options?
The answer may be yes. Patients with very high prescriptions can consider intraocular implants. There are two types of implants for patients who suffer from extreme nearsightedness or farsightedness. There are implants that can be inserted near the iris, the colored part of the eye, and therefore do not require the removal of the eye’s natural lens; however, this technology is still at an early stage of development. A clear lens extraction, in which the natural lens of the eye is removed and replaced by an intraocular lens, is a more reliable procedure. In addition to distance correction, ReZoom® and ReSTOR® lenses are two types of multifocal intraocular lens implants which can improve near vision for reading.
Other alternatives to laser eye surgery
Conductive keratoplasty is a technique in which the collagen fibers of the cornea are heated with radio waves to induce a steepening of the cornea. One reason this procedure is quite popular is that it can be used to treat presbyopia, something that laser surgery is not yet capable of. Only small farsighted prescriptions can benefit from this technology, and it cannot correct astigmatic prescriptions.
Intacs are thin, circular plastic strips that are placed into the cornea in order to flatten the central part of the cornea. They cannot correct astigmatism but may be helpful in patients with abnormally shaped corneas, which occurs in keratoconus.
There is a new player in the refractive surgery world called SMILE. If LASIK and PRK were not available, it would be a fantastic option. However, as usual for any new procedure, there is hype and then the reality.
So, why are LASIK and PRK still favored over SMILE?
It begins with how you correct the prescription on the cornea. The correction with LASIK and PRK is achieved with an excimer laser, whereas a femtosecond laser is used for the SMILE procedure. Simply put, the excimer laser is more precise because it utilizes customized wavefront technology integrated with topographical analysis, something SMILE and the femtosecond laser cannot do. Dr. Mandel uses the iDesign Refractive Studio, which is the only system with this proprietary technology. In addition, patients see better sooner with LASIK than with SMILE.
