Our Technology

CustomVue – ReSTOR – Crystalens – NearVision CK

A key component in quality vision care is technology.

When you decide to undergo LASIK or other types of vision correction, you want to know that the equipment being used on your eyes is first class. Dr. David I. Malitz believes that much of a surgeons responsibility to his patients applying advanced technology in a safe and effective manner. To stay on the cutting edge of LASIK laser vision correction, Dr. Malitz constantly evaluates new technologies that can offer the best treatment options for patients.

Among the latest technology in use at the Southwest Eye Institute is:

WaveFront Mapping and WaveFront Guided LASIK
Now its possible to capture, measure and treat both lower and higher-order visual errors with the new and advanced WaveFront Mapping technology.

CustomVue Technology- The Fingerprint of Your Vision

Your vision is unique – as personal as your fingerprint or your DNA. WaveScan technology provides your eye doctor with a map of your eye.

WaveScan Technology-

Southwest Eye Institute was among the first in the region with this technology. Initially you will meet with your eye doctor for a complete medical evaluation and eye history to determine whether you are a good candidate for the CustomVue procedure. Your doctor will discuss the benefits and risks of the procedure with you. A WaveScan measurement will be taken to map the unique characteristics of your eye. With this map, your doctor will be able to:

  • Accurately assess whether you’re a good candidate for laser vision correction. Anyone who is considering laser vision correction should obtain a WaveScan measurement as the first step.
  • Along with the other diagnostic tests that your doctor performs, an individualized treatment plan can then be developed to address your unique vision needs. 
    Once it is confirmed that you are a good candidate, your doctor will schedule you for a CustomVue procedure. Your doctor will provide details to you on how to prepare for the day of the procedure.

Nidek OPD Wavefront Analyzer-

Southwest Eye Institute was among the first in the region with this technology and is the only one still. We feel that one of the most critical components of a successful outcome is accurate and percise measurements. This is why we not only use one but two wavefront analyzers to capture your perscription and minimize the uncertainty of a patient chosing between “choice one or two”. This device captures not only a wavefront of the visual system, it also captures the topography of the cornea (shape) and the refraction (presscription to the hundredth of a diopter!). This yields a perscription that is 25 times more percise than a standard phoropter (standard device to test vision).

The CustomVue Procedure-

On procedure day, you will be seated in a reclined position. Anesthetic drops will be placed in your eyes and a flap will be created on your cornea. Your individualized treatment information is reviewed and modified by the surgeon and is transferred from the WaveScan to the laser in order to drive the CustomVue procedure. The actual laser procedure typically takes less than thirty seconds. Most individuals feel no pain during the procedure.

After CustomVue, you will notice results immediately and your vision will continue to improve over the next few days. Typically, you will be scheduled for a follow-up visit the next day, again in about a week and again around a month after the initial procedure.

CustomVue Technology – Star S4 Laser

The VISX STAR S4 Excimer Laser System-

The VISX STAR platform’s heritage of dependability and performance is well known. The STAR S4 from VISX has taken that reputation to an even higher level. Our excimer laser system represents an advanced laser technology platform. The Visx platform is chosen by more surgeons in the USA than any other laser. By integrating data collected by the WaveScan WaveFront System, the STAR S4 utilizes these exclusive VISX technologies to deliver precision custom ablations:

 

 

 

 

  • Variable Spot Scanning (VSS): Variable beam sizes from as small as 0.65 mm up to 6.5 mm scanned over the treatment area, conserving tissue and optimizing treatment times
  • Variable Repetition Rate (VRR): VRR delivers treatment at varying repetition rates, optimizing treatment time
  • ActiveTrak 3-D Active Eye Tracking: Captures all 3 dimensions of intra-operative eye movements ®no dilation required
  • ActiveTrak Automatic Centering: Locates, and then automatically sets the treatment center to the center of the pupil.

Beyond Glasses and Contacts-

  • Glasses and contacts are limited in their ability to correct unique imperfections in each individual’s vision. In fact, thousands of individuals have the same prescription. With the CustomVue procedure, no two ®prescriptions® are identical.
  • This precise level of measurement and treatment can enable individuals to achieve the full potential of their vision.

Clinical Study Results-

VISX’s FDA clinical study results were remarkable. Among other things:

  • At one year after the VISX CustomVue procedure
    1. 100% of the clinical study participants could pass a driving test without glasses or contacts
    2. 98% of the clinical study participants could see 20/20 or better without glasses or contacts
    3. 70% of the clinical study participants could see 20/16 or better without glasses or contacts.
  • Four times as many clinical study participants were very satisfied with their night vision after the VISX CustomVue procedure compared to their night vision before with glasses or contacts.

Crystalens

crystalens_imageCrystalens offers significant advantages over other kinds of lens implants and corrective lenses. Standard (single vision) lens implants don’t have the ability to provide a full range of vision. Most people who have single vision lens implants MUST wear glasses for middle and near vision. Crystalens has the unique ability to focus on objects at varying distances using the eye®s natural muscle. This means the Crystalens can provide sharper vision, without corrective lenses, throughout a full range of vision from near to far and everything in between.

 

Crystalens® FDA one-year clinical study results indicate:

  • 92% of the people enrolled in the study (implanted bilaterally) could see 20/25 or better at distance
  • 96% could see 20/20 at arm®s length
  • 73% could see 20/25 at near
  • 98% of these people could pass their drivers test
  • 100% could see their computer or put on their makeup
  • 98% could read a magazine, all without glasses or contact lenses.

Also, your ability to see at approximately arm®s length (middle vision) will be greatly enhanced with the Crystalens. In addition, the quality of vision compared to wearing bifocals and/or trifocals is significantly improved. You’ll have a full range of vision by simply looking at something. Crystalens, mimicking the natural focusing ability of your eye, will automatically focus your eye at near, arm®s length, or distance.

ReSTOR – What is is?

restor_imageThe AcrySof® ReSTOR® Apodized Diffractive Optic Posterior IOL (ReSTOR®) is a permanent artificial lens. ReSTOR® is implanted in the eye to restore vision after the natural lens is removed because of cataract with or without presbyopia (over 40 vision). Ask us about the new ReStor 3 plus. Designed to enhance near without sacrificing intermediate vision.

The ReSTOR® lens is convex on both sides and made of a soft plastic. It is folded and inserted into the eye through a tiny incision smaller than the optic diameter of the lens. After insertion, the lens gently unfolds to restore vision. The supporting arms (haptics) of the lens maintain proper positioning within the eye.

How does it work?

The AcrySof® ReSTOR® IOL replaces the natural lens. It has a patented optic design using apodization, diffraction and refraction technologies. The apodized diffractive optic design gives it the ability to focus light correctly on the retina for images at various distances without mechanical movement of the lens.

  • Apodization is a gradual reduction or blending of the diffractive step heights.
  • This unique technology optimally manages light energy delivered to the retina because it distributes the appropriate amount of light to near and distant focal points regardless of the lighting situation.
  • Apodized diffractive optics are designed to improve image quality while minimizing visual disturbances. The result is an increased range of quality vision that delivers a high level of spectacle freedom.

When is it used?

The AcrySof® ReSTOR® IOL is used in adult patients with and without presbyopia, who desire near, intermediate and distance vision with increased independence from glasses following cataract surgery.

What will it accomplish?

The AcrySof® ReSTOR® IOL has been shown in a clinical study to provide good near, intermediate and distance vision with increased independence from glasses in patients who have undergone cataract surgery.

CONSIDER THE PRICE:

What is the price you put on reading the print in a book? Or on a menu? To clearly follow your golf ball as it sails over the fairway? Your vision connects you to your world and your loved ones in so many ways. With ReSTOR®, you don®t have to miss any of it.

Insurance coverage varies greatly from policy to policy and state to state. Generally speaking, private insurance may cover the cataract surgical procedure and anesthesia and may also allow a certain additional amount for the artificial lens implant. The insured is then required to pay a deductible as well as any additional amount above the primary coverage. (Some patients are responsible for the total payment. Not all insurance companies will cover some.)

Your surgical counselor will review your insurance coverage and your surgical alternatives prior to your cataract surgery. It may also be beneficial for you to contact your insurance carrier.

CLINICAL RESULTS:

The FDA-approved AcrySof® ReSTOR® is a breakthrough in intraocular lens technology for most people with cataracts, with or without presbyopia, that may restore the eyesight of youth. Results from a controlled clinical study of the AcrySof® ReSTOR® IOL revealed that maximum visual performance is achieved when implanted bilaterally.

Clinical data demonstrates that AcrySof® ReSTOR® IOL greatly reduces dependence on glasses or bifocals:

  • 80% of patients reported that after lens implant surgery with ReSTOR® lenses, they never needed glasses or contact lenses to see clearly at all distances.
  • 94% reported being able to drive or read the newspaper without glasses or contacts
  • Nearly 94% were so satisfied that they would have the procedure again.

In addition, the quality of vision compared to wearing bifocals and/or trifocals is significantly improved. You®ll have a full range of vision without having to tilt your head to find that portion of your glasses that allows you to see clearly.

Everyone®s focusing ability is different. Most people will be able to see clearly in the distance, have very good reading vision and good middle vision without glasses, but some people may be more comfortable with additional correction, particularly at night or in dim light or for long periods of computer work.

It is important to remember that implant surgery cannot resolve pre-existing visual conditions such as floaters, flashes, or visual field loss that are a result of conditions of the eye and not related to the lens. While virtually everyone experiences much improved vision after cataract surgery, some people will have better uncorrected vision than others.

It may be necessary for some people to wear glasses for distance, intermediate and/or near vision to obtain optimal visual acuity. The difference from standard lenses is that most people will not be dependent on these supplemental vision aids to function normally.

RESTOR® IOL CANDIDATES:

Virtually everyone who has cataracts and is in good general health may be a candidate for implant surgery. But people with chronic infections, uncontrolled diabetes, or other health problems may have to wait until these conditions are under control prior to surgery.

People who have had prior corneal refractive surgery (i.e. LASIK or PRK) may be acceptable candidates for ReSTOR® implantation as long as their eyes are in good health. After a thorough examination, we will be able to better advise you if you qualify for the ReSTOR implant.

If you’ve already had cataract surgery, you’re not a candidate for the ReSTOR® procedure.

ReZoom – What is is?

ReZoomThe AMO ® ReZoom® Implant or “IOL” is a permanent artificial lens. ReZoom® is implanted in the eye to restore vision after the natural lens is removed because of cataract with or without presbyopia (over 40 vision).

The ReZoom® lens is convex on both sides and made of a soft acrylic. It is folded and inserted into the eye through a tiny incision smaller than the optic diameter of the lens. After insertion, the lens gently unfolds to restore vision. The supporting arms (haptics) of the lens maintain proper positioning within the eye.

How does it work?

The AMO ® ReZoom® IOL replaces the natural lens. It has a patented multifocal optic design. The optic design gives it the ability to focus light on the retina for images at various distances without mechanical movement of the lens.

  • Refractive Zonal-Progressive design.
  • This unique technology optimally manages light energy delivered to the retina because it distributes the light to near, intermediate and distant focal points regardless of the lighting situation.
  • The optic design allows improved image quality while minimizing visual disturbances. The result is an increased range of quality vision that delivers a high level of spectacle freedom.

NearVision CK – Conductive Keratoplasty

ck_imageWhen we turn 40, our eyes begin losing their ability to easily focus on near objects. This can be the result of two different conditions:

Presbyopia: When the lens in the eye loses flexibility because of age. This causes problems in the way our eye focuses light. Most people over age 40 and everyone over age 50 suffers from this condition.

Farsightedness (hyperopia): When the surface of the eye (cornea) is too flat, changing the way our eye focuses light. Young eyes are often strong enough to compensate, which is why it may only be a problem after age 40. CK can change how the eye focuses light by reshaping the surface of your eye (cornea). When the shape is changed, light can be refocused on the correct part of your eye (retina).

To produce this reshaping, CK uses the controlled release of radio frequency energy (instead of a laser) to heat and shrink corneal tissue. This steepens the cornea and allows light to properly focus on the retina again, improving near vision. CK is intended for people over 40 years of age who want to improve their near vision. If you are over the age of 40, had good vision without glasses and contact lenses for most of your life and now need reading glasses, you may be a candidate.
