Wavefront Technology and LASIK
LASIK (Laser in Situ Keratomileusis) is one of the most exciting and successful surgical procedures performed today. Over the years since its development, we have continued to improve to it, increasing the success rate and decreasing the complications, making it a safer and better procedure, with superior visual results and more rapid rehabilitation. In the past few years, we have had advances such as the addition of scanning spot laser delivery and eye tracking technology, which increased the precision of the procedure and decreased the risk of glare and halos. Now with Wavefront technology and the CustomVue procedure, the next generation of laser vision correction has arrived.
Wavefront technology is a new way of recording the irregularities of the eye and allows us to customize the laser treatment to the individual patient's eye. Wavefront sensing, performed by the WaveScan device, examines the eye's important structures and creates a Waveprint of the eye. This information is then compared to the other measurements taken during Dr. Sperber's careful preoperative examination, and then a customized laser ablation pattern is created by the WaveScan machine. Once completed, the customized ablation pattern is transferred to the excimer laser which then uses this information to perform a CustomVue treatment, eliminating the eye's aberrations, improving the patient's vision beyond what was possible with previous treatments.
The results with CustomVue excimer laser treatments are vastly superior to standard laser ablation. During the clinical trials, 98% of patients achieved 20/20 vision or better, with 70% of patients achieving 20/16 vision at the 12 month follow up visit.
These outstanding results and tremendous patient satisfaction have prompted us to adopt the use of this exciting new technology, as we continue our commitment to provide our patients with the best quality care possible.

New Technologies in LASIK
LASIK (Laser In Situ Keratomileusis) is one of the latest developments in laser vision correction. In LASIK, an instrument called a microkeratome is used to create a thin flap in the cornea. The excimer laser then gently reshapes the cornea beneath the flap and the flap is then put back in place. By reshaping the cornea, LASIK can correct nearsightedness, astigmatism and farsightedness.
LASIK, as with any other new and innovative technology, is in constant evolution. The first generation excimer lasers used in LASIK were broad beam lasers. These lasers used a single laser beam that was acted upon by an iris diaphragm to control and change the diameter of the laser ablation. These lasers provide excellent results, with hundreds of thousands of patients around the world benefiting from improvement in their vision thanks to these lasers. We continue to make improvements in excimer laser technology and as these advances become available, we evaluate them and select the best of these advanced laser systems to use on our patients.
Two such innovations have now become available and, in keeping with our tradition of offering the best that technology has to offer to our patients, we are now using them to perform our LASIK procedures. The first of these technologies is the use of a scanning or flying spot laser for ablation. A scanning spot laser uses a smaller spot (typically 1 or 2 mm) to treat the cornea, moving it around the ablation zone in an exact, computer-controlled fashion. The scanning spot represents an improvement over the broad beam laser in that the laser ablation is much smoother. The only disadvantage to the scanning or flying spot laser is that the laser ablation takes a little longer. Once again, technology has offered a solution. Our laser system offers the best of both worlds. Using a combination of broad beam and scanning spot technology, the laser ablation offers the speed of broad beam technology and the smoothness of a scanning spot laser. The second innovation we are using is the addition of an eye tracker to our laser system. An eye tracker follows the movement of the eye with pinpoint precision, directing to laser treatment to follow the motion of the eye, and placing the pulses carefully centered on the patients' pupil, thus minimizing the risk of an off-center ablation, which could lead to problems in vision.
These two technological advancements, the combined broad beam and scanning spot laser and the eye tracker, have greatly improved upon the precision and accuracy of our LASIK procedures, improving the outcomes and minimizing the risk of side-effects like glare and haloes around lights.
The constant addition of technological innovations to this already outstanding LASIK procedure is part of our commitment to provide the best in quality care to our patients.

Laser Cataract Surgery
There have been many exciting innovations in cataract surgery over the past few decades, but none as exciting as the most recent development in cataract surgery: Laser Cataract Surgery. Dr. Sperber has been working with Dr. Jack Dodick (the inventor of the procedure) on this most exciting development in cataract surgery known as Dodick Laser Photolysis. This technique uses laser energy to break up the cataract, which can then be removed through an incision that is less than 1.5 millimeters in length (less than half the length of the incision used in the current procedure for cataract removal).
There are several advantages of this procedure over the present technique, ultrasound phacoemulsification. First, because much less energy used in the cataract removal, it is safer to the surrounding tissues inside the eye. Second, because the incision is so small, this allows for even more rapid healing than the present techniques we use in cataract surgery.
The Laser Photolysis procedure starts with the surgeon making two small incisions with a specially constructed diamond blade. The capsule of the cataract is opened in the conventional fashion and the two probes used in the procedure are introduced into the eye. The cataract is broken up into small pieces and aspirated out of the eye through these extremely fine probes. After the cataract is completely removed, the incision is enlarged slightly and a foldable intraocular lens implant is inserted into the eye. Before the surgery is completed, ORA™ System technology can be used to confirm the type and power of the lens is appropriate. The tiny incisions seal without any stitches and the patient can get up and walk out of the operating room almost immediately after surgery.
Because the incisions are so small, recovery is extremely rapid and the patient can return to normal activities the next day.
Laser Photolysis has been used in Europe, South and Central America and in Canada for several years now. Dr. Sperber has worked with Dr. Dodick and experts all around the world in the development of this device. Because of his work, Dr Sperber is one of the most experienced Laser Cataract Surgeons in the world. The Food and Drug Administration Device Advisory Panel (FDA) approved this procedure in June of 2000 and we have been performing this exciting new procedure on our patients, with great success since that time. If you are interested in Laser Cataract Surgery and the tremendous advantages it has over conventional surgery, please contact Dr. Sperber to see if you are a candidate for this exciting, innovative procedure.
