Wavefront can be used for virtually all laser eye surgery techniques including All-Laser Lasik, Lasik, PRK, LASEK, and Epi-Lasik.

In wavefront custom Lasik, PRK, LASEK, and Epi-Lasik, the excimer laser uses wavefront information to change the shape of the cornea by ablating tissue.

In all refractive surgery procedures, wavefront or conventional, HOA tends to increase.

A wavefront diagnostic can determine if an individual has aberrations that would be exacerbated by refractive surgery to the point of causing vision problems.

Custom wavefront-guided Lasik, LASEK, PRK, and Epi-Lasik directs the excimer laser to change the shape of the cornea using a more detailed mapping system than conventional refractive surgery.

Wavefront-guided laser ablation for custom Lasik and other refractive eye surgery has been a significant improvement for most individuals, but not for all.

Virtually every person considering Lasik, LASEK, PRK, or Epi-Lasik should have a wavefront diagnostic evaluation.

It is a type of refractive surgery which reshapes the cornea by removing microscopic amounts of tissue from the corneal stroma, using a computer-controlled beam of light .

Some people’s eye shape may not permit effective refractive surgery without removing excessive amounts of corneal tissue. According to surveys of members of the American Society of Cataract and Refractive Surgery, approximately 948,266 refractive surgery procedures were performed in the United States during 2004 and 928,737 in 200 Although the risk of complications is decreasing compared to the early days of refractive surgery, there is still a small chance for serious problems.

This year, an estimated 5 million Americans will have refractive surgery, and it is no longer something just for risk takers. If you’re considering refractive surgery, it’s imperative that you learn from comprehensive, unbiased and up-to-date information sources, and make a well-informed decision about whether LASIK or other refractive surgery is right for you.

Epi- LASIK Epi-LASIK is a refractive surgery procedure used to treat nearsightedness , farsightedness and astigmatism.

When treating myopia, or nearsightedness, certain refractive surgery techniques reduce the curvature of the cornea to lessen the eye’s focusing power. You may not be a good candidate for refractive surgery if you are generally satisfied with glasses or contact lenses and unwilling to accept the uncertainty in the outcome of refractive procedures. Phakic IOLs are designed for people with high degrees of refractive errors which cannot be safely corrected with corneal-based refractive surgery.

PRK is an outpatient procedure generally performed with local anesthetic eye drops. Decrease in Best-Corrected Vision: After refractive surgery, some patients find that their best obtainable vision with corrective lenses is worse than it was before the surgery. With that approval, the agency also restricted use of the laser to practitioners trained both in laser refractive surgery and in the calibration and operation of the laser. Pregnant women should not have refractive surgery of any kind because the refraction of the eye may change during pregnancy.

The most common methods today use excimer lasers to reshape curvature of the cornea. Refractive eye surgery is any eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses.

James Salz is currently involved in an FDA-sanctioned clinical trial at Cedars-Sinai Medical Center in Los Angeles, which is now studying the laser system specifically for farsightedness with astigmatism. Although routinely performing laser eye surgery, he still encourages a small percentage of his low to moderately nearsighted patients to undergo radial keratotomy, or RK, an earlier refractive correction procedure that does not require the excimer laser. Goldstein underwent refractive eye surgery, an elective procedure intended to correct common eye disorders, known as refractive errors, such as myopia , hyperopia , and astigmatism .

In 1986 Dr Swinger improved the surgery but it was still a slightly imprecise technique.

Lens implantation inside the eye can also be used to change refractive errors. Visit the Consumer Guide to LASIK & Laser Eye Surgery for more information about LASIK and vision surgery.

Images that are focused beyond the retina, due to a short eye or flat cornea, are pulled closer to or directly onto the retina following surgery.

CK is a non-invasive, thermal refractive surgical procedure used to correct mild to moderate farsightedness in people over age 4 FDA is aware of a few instances of severe eye injury requiring corneal transplant.

Although there are several types of surgical techniques being performed today to correct refractive errors, laser refractive correction is fast becoming the most technologically advanced method available, according to the American Academy of Ophthalmology in San Francisco.

Is it painful?

“Initially, I wanted the quick recovery that LASIK offers,” Goldstein says, “but the bottom line was, which surgery will give me the best results, and after considering everything, eventually we agreed on PRK.”

When will I be able to return to work?

If you are considering LASIK eye surgery, your first step is to choose a good LASIK surgeon choose a good LASIK surgeon who can evaluate whether LASIK is right for you.

If you are ready to choose a doctor to be evaluated for conventional or wavefront custom Lasik, All-Laser Lasik, PRK, LASEK, Epi-Lasik, NearVision CK , RLE , or any refractive surgery procedure, we highly recommend you consider a doctor who has been evaluated and certified by the USA Eyes nonprofit organization.

CONCLUSION: Toric ICL implantation was better than wavefront-guided LASIK in eyes with high myopic astigmatism in almost all measures of safety, efficacy, predictability, and stability, suggesting that toric ICL implantation may become a viable surgical option to treat high myopic astigmatism.

While the non-dominant eye will need to be undercorrected with a conventional ablation, the dominant eye may be fully corrected with a wavefront-guided ablation.

TLC Laser Eye Centers strive to make LASIK affordable.

LASIK stands for Laser-Assisted In Situ Keratomileusis and is a procedure that permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser.

Patients can expect a short LASIK surgery recovery period LASIK surgery recovery period but there is usually little to no discomfort following the procedure.

Patients who have experienced an eye infection or injury in the past year should not undergo LASIK.

.

The Wavefront LASIK device collects information by using light reflected off the retina and through the pupil, and into the device, creating your unique map reflecting your lower or higher order aberrations. A patient’s unique visual irregularities are contained in this map, which is then sent to the laser via computer.

With a wavefront measurement system, some extremely precise, individualized vision correction outcomes may be achieved that would be impossible with traditional LASIK surgery , contact lenses or eyeglasses. Uncorrected visual acuity of 20/20 or better was achieved by similar numbers, however: 72 percent of the wavefront group and 70 percent of the regular LASIK group.

Wavefront can be used for virtually all laser eye surgery techniques including All-Laser Lasik, Lasik, PRK, LASEK, and Epi-Lasik. Something very important to understand is that not all aberrations are reduced with custom wavefront or wavefront optimized Lasik, PRK, LASEK, or Epi-Lasik.

Wavefront technology as a diagnostic device is unsurpassed. This technology can diagnose and measure aberrations that no other system can even see. It is important to understand that without a wavefront diagnosis, it is impossible for a doctor to accurately determine if wavefront-guided ablation is necessary for a good Lasik, PRK, or LASEK outcome.

The first is a wavefront evaluation and diagnosis of existing aberrations. The second is using what is learned from the diagnosis to create a wavefront-guided ablation for Lasik, PRK, LASEK, or Epi-Lasik. In wavefront custom Lasik, PRK, LASEK, and Epi-Lasik, the excimer laser uses wavefront information to change the shape of the cornea by ablating tissue. The primary difference between conventional Lasik and wavefront custom Lasik is the mapping system that guides the laser.

The doctor looked in my eyes and told me that I was a candidate for regular Lasik and Custom, or Wavefront, Lasik. For the vast majority of patients, Custom Wavefront Optimized LASIK will produce excellent results. For more complex prescriptions, a true Custom Wavefront Guided LASIK will be the procedure of choice.

This creates an optical map of the eye, highlighting individual imperfections. Wavefront technology functions as a roadmap for LASIK surgery, providing benefits to the patient during both the evaluation and treatment process. Wavefront Diagnostics & Custom Treatment Summary Wavefront-guided LASIK is a promising new technology that provides an advanced method for measuring optical distortions in the eye.

Measuring and treating these distortions goes beyond nearsighted, farsighted, and astigmatism determinations that have been used for centuries.

BACKGROUND: The aim of this study was to analyze the distribution of total, corneal, and mainly internal human third- to sixth-order aberrations (HOA) and investigate possible correlations between wavefront errors and patient age.

PATIENTS AND METHODS: For this study 140 eyes of 140 subjects (age range 17-77 years) were measured three times each using Nidek Optical Path Difference scan.

CONCLUSIONS: The internal, corneal, and total wavefront aberrations varied widely among patients.

A reflecting mirror within the telescope that can be deformed is adjusted using wavefront data to eliminate aberrations induced by the Earth’s atmosphere.

RESULTS: There was wide individual variation in the internal wavefront aberrations. A wavefront diagnostic can determine if an individual has aberrations that would be exacerbated by refractive surgery to the point of causing vision problems. No other technology can achieve this level of diagnosis.

Wavefront diagnostic can determine if a wavefront guided ablation is an absolute requirement, conventional ablation would be fine, or the patient should not have surgery at all. A conventional eye exam can map LOA. A wavefront diagnostic can map LOA and HOA.

Laser eye surgery based upon the LOA determined with a conventional eye exam is like using a map of your state to find your way around. That works pretty well if you are trying to get from Los Angeles to San Francisco.

HOA may increase no matter what you choose, but it will probably increase less with wavefront. Because HOA is likely to increase, if your natural HOA are already elevated, refractive surgery may elevate them farther and cause poor vision. In this situation, it may be that no corneal-based refractive surgery is appropriate.

Wavefront is a very old technology that has only recently been applied to human vision. Wavefront has been used for years by astronomers who need to adjust the optics of their telescopes.

Wavefront technology enables the surgeon to improve overall vision quality better than in the past.” Wavefront-guided LASIK may be less likely to induce higher order aberrations than conventional LASIK, according to discussion in the April 15, 2005 issue of Ophthalmology Times. A 2005 survey revealed that most refractive eye surgeons now use wavefront-guided LASIK in their practices.

A 2006 Staar Surgical report estimates that about 1.4 million LASIK procedures currently are performed annually in the United States, about half of all procedures worldwide. Custom LASIK usually costs significantly more than traditional LASIK, partly because a fee is paid to the device manufacturer for each procedure.

Since I was already paying for the procedure, I decided that I might as well pay for the best and chose the Wavefront approach.

To achieve a customized corneal shaping, it will require measuring the higher order optical aberrations using a wavefront analysis system called an Aberrometer and then digitally interfacing it with a laser, using high speed computerized control to direct the delivery of a very tiny beam of laser energy across the cornea.

If the wavefront is advanced (in front of the referenced wavefront), the laser must remove less tissue. It should be noted that wavefront treatment does induce some minor second-order spherical errors, but to a significantly lesser extent than conventional refractive surgery.

In this way, a wavefront-guided treatment is customized to the characteristics of each eye and intended to minimize higher-order aberrations so that the greatest quality of vision can be achieved. To clarify the confusion about light traveling as waves instead of rays, waves are just perpendicular to light rays.

These light waves are wrinkled or distorted as they pass through imperfections in the eye. These errors can be displayed on a color map of the wavefront image, which is the tool that is used to diagnose, and then determine corrections, for abberrations in the eye.

The amount of wrinkle or error in the wavefront reflected from the back of the eye, as compared to the reference wavefront that was projected into it, defines the compensating optical correction.

If the wavefront is retarded in relation to the reference wavefront, the laser must remove more tissue from the part of cornea related to that pattern. Light can be thought of as traveling in a series of flat sheets, known as wavefronts.
