ZD VISION, ZD LASERVISION, and ZD LASIK

ZD VISION is our term for our comprehensive approach to Vision Correction Surgery, which includes ZD LASIK and ZD LASERVISION. ZD VISION incorporates a number of individual items which we have found important in or goal of providing our patients with the best quality of vision, in the safest way we know how.

ZD Vision has a number of components which are common to ZD LASERVISION and ZD LASIK.

ZD VISION includes:

• Zero Defects Vision- our quality assurance program. Although we cannot guarantee every patient will have perfect vision after surgery, we are committed to constantly improving our results. We utilize computer programs to measure many aspects of vision and ocular dimensions pre-operatively, and then asses our surgical outcomes using specific outcomes analysis computer programs for both out lens based surgery and our corneal refractive surgery. The goal is to have the best outcomes, and the way to move closer to that goal is to measure the parameters involved, and the visual outcomes, and assess them to see where we can improve. No human enterprise is perfect, but highly technical human activity like eye surgery requires a commitment to constant improvement, which is what has brought it to its current state of development and will lead to future improvements.
• Zero Down Vision- our payment plans designed to help make vision correction surgery affordable for all. We have payment options for corneal laser vision correction as well as lens based vision correction, and accept most medical insurances, as applicable.
• Zero Dry eyes- our program to proactively assess dry eye before surgery and to improve the tear status before surgery, address it during surgery, and treat it after surgery to maximize vision and comfort. This is especially important in LASIK and other forms of laser vision correction.
• Zero Disappointment Vision correction surgery- our commitment to providing you accurate and specific information about your options, so that you can make an informed choice and understand not only the benefits of the surgery, but the potential risks and side effects as well. Although no surgery is risk free, we attempt to look at the different elements involved and ask ourselves how we can make it better and safer, and achieve the highest level of patient satisfaction that we can. . It is very important that you understand what the varieties of vision corrections are for you, both with glasses, contact lenses and surgery, and understand the inherent risks involved, so you can make an informed decision regarding whether surgery is a reasonable option for you. We view eye care as a partnership between our staff and our patients, and want you fully involved in your care. Your suggestions are an important part of our goal of constant quality improvement, and we welcome them.
• Zernike Derivative Vision correction surgery - not only do we attempt to correct your vision with regard to nearsightedness, farsightedness, and astigmatism, but we also evaluate the focusing power of your cornea and lens across the pupil, and evaluate the corneal topography and the wavefront of light entering your eye. The ability to measure these parameters allows us to customize your surgery, and address the higher order aberrations in your eye, described mathematically by the Nobel physics laureate, Zirenicke. These are important elements in the quality of vision post-operatively, especially for vision under low light situations or under conditions when light is shining in your eye, collectively often referred to as Night Vision Defects, as discussed below.
• Zero night vision Defects. Originally, LASIK surgery was very successful in reducing or eliminating the need for glasses, but a significant minority of patients noted some night vision problems. Advances in the consistency of laser beam delivery, selecting appropriate central optical zones and peripheral transition zones, understanding the effect of pupil size on visual quality, and evaluating and where appropriate correcting wavefront aberrations in laser vision correction are all examples of our program to minimize aberrations after vision correction surgery by customizing the technology to each eye.
• Zero Discomfort refers to our desire to have your surgery experience be as comfortable and pain free as is possible. This not only adds to the experience, but increases safety and the quality of the result.
• Zero Displacement refers to our desire to assure that patients do not move during surgery and do anything which might diminish their chances for a successful outcome. For lens based surgery, we provide what we have found to be the best and safest form of local anesthesia, and we secure the patient head so that it does not move during the procedure. For LASIK, topical anesthesia and sedation have been found to be the best solution, and we assure patients that, although it is important to look at the laser beam during surgery.
• Another aspect of Zero Displacement surgery is centering the eye during LASIK, and assuring that it stays centered during treatment. A device called an eye tracker is used to.
• An emerging area of focus in vision correction surgery is comparing the centration of laser vision correction over the pupil as opposed to centering it over the line of sight. Briefly, inmost patients, these two points are so close together as to not be a problem and to be clinically unimportant, but in some patients, the visual axis of the eye and the center of the pupil are not coincident.
• Z Dimension Vision refers to our options of providing you with vision at distance and close up. In middle age, the lens in our eye loses its flexibility , needed to bring the focus form distance to close objects, That is why middle age people begin to need reading glasses, or if they wear glasses need to wear bifocals, trifocals, or a progressive addition lens ( no line bifocals). We have options for patients considering LASIK, utilizing monovision (intentionally leaving one eye slightly nearsighted to allow for reading vision), doing the same for lens based surgery patients, or utilizing the new premium presbyopia correcting intraocular lens implants for patients having lens based surgery.
