What's new in LASIK procedures?
Lasik Alternative Approved by the FDA. The Food and Drug Administration in September approved a new laser eye procedure known as Small Incision Lenticule Extraction, or SMILE. Noel's doctor recommended giving it a try. The procedure employs a laser, similar to the one used in LASIK, to remove a small piece of the cornea to reshape the eye.
Is Lasek more like LASIK or PRK?
PRK has been around much longer than LASIK, but both are still widely used today. LASEK, like LASIK, also corrects major refractive errors. What Happens During a LASEK Procedure?
What is the latest laser eye surgery technology?
The latest laser eye surgery procedure The latest development in laser eye surgery is ReLex SMILE. This is a minimally invasive, bladeless form of keyhole laser eye surgery which offers a superb alternative to more traditional forms of surgery.
What is the newest LASIK technology?

The WaveLight® EX500 Excimer Laser system combines a number of innovations in refractive technology to produce fast, effective and reliable procedures. 1–4 Its proven, state-of-the-art technology results in excellent Wavefront Optimized® and Wavefront-Guided laser vision correction.
What is the most advanced LASIK technology?
Wavefront-Guided This technique is the most advanced type of custom LASIK. It creates a three-dimensional image of your eye, measuring exactly how light enters the cornea and travels to the retina. It precisely attempts to correct all higher-order aberrations, in addition to myopia, hyperopia, and astigmatism.
Has LASIK technology improved?
These advances in technology have significantly improved the safety and effectiveness of LASIK surgery today. In fact, it's never been safer.
Which laser is best for LASIK?
The introduction of Femtosecond laser increased the precision and accuracy of flap making as compared to the micorkeratome blade. Hence Femto-Lasik was also called bladeless LASIK. Femto-Lasik thus allowed the laser vision correction surgery to become even more safer by adding extra precision.
What is the difference between LASIK and ultra LASIK?
In femto Lasik, the laser used is femtosecond laser an extremely precise laser beam is directed on the cornea to create a microscopically thin corneal flap. While in ultra Lasik, the laser creates an ultra-thin corneal flap. This allows the surgeon to place the flap at the most ideal position for best results.
Whats better LASIK or PRK?
If you're active, you might prefer LASIK because you'll have clear vision faster. But if you're into contact sports, PRK might be best because LASIK requires the doctor to cut a flap on your cornea, and it could get knocked loose. PRK may be a better choice for people with thin corneas and dry eyes.
Who is not a good candidate for LASIK?
Patients with autoimmune diseases are not good LASIK candidates. Many autoimmune conditions cause dry eye syndrome. A dry eye may not heal well and has a higher risk of post-LASIK infection. Other conditions such as diabetes, rheumatoid arthritis, lupus, glaucoma or cataracts often affect LASIK results.
Does eyesight deteriorate after laser eye surgery?
Eyesight After LASIK Many patients will never have to wear contact lenses or glasses ever again. Your vision may change after surgery, but if it does, LASIK will still be beneficial. Changes in vision after LASIK are typically minor, and most people report improved eyesight for a lifetime after their procedures.
Is Wavefront LASIK the best?
Custom Wavefront LASIK is the most superior form of laser vision correction. If you are looking to treat vision impairment and would like to learn more about this advanced technique, schedule an appointment with Dr.
What LASIK Cannot correct?
This results in presbyopia, also known as age-related farsightedness. LASIK corrects vision by reshaping the cornea, and it is unable to reverse the physiologic changes happening in the lens which cause presbyopia.
What age is good for LASIK surgery?
Generally speaking, most LASIK eye surgeons agree on 25-40 as the ideal age range for LASIK eye surgery candidacy for a few reasons. By the age of 25, eyeglasses and contact lens prescriptions have most likely stabilized. A stable prescription is one of the hallmarks of a good LASIK candidate.
What are the 3 types of eye surgery?
There are three main corrective surgeries: LASIK, LASEK, and PRK. All three of these procedures are designed to reshape your cornea.
Is Wavefront LASIK the best?
Custom Wavefront LASIK is the most superior form of laser vision correction. If you are looking to treat vision impairment and would like to learn more about this advanced technique, schedule an appointment with Dr.
What is SBK advanced LASIK?
SBK – Advanced LASIK Sub-Bowman's Keratomileusis (SBK) is a modern and advanced LASIK alternative. SBK is individually customized to each eye using only bladeless technology. It offers a rapid recovery with incredibly accurate results.
Which eye corrective surgery is best?
Without a doubt, the most famous type of corrective laser eye surgery is LASIK, or laser-assisted in-situ keratomileusis. For those with refractive errors like nearsightedness, farsightedness, or astigmatism, LASIK has become the gold-standard procedure.
Which is best femto lasik or SMILE?
In that early study, 96% of SMILE patients achieved 20/20 or better uncorrected with 12% at 20/16 or better, compared with 88% and 4% respectively for femto-LASIK three months after surgery, Dr Ganesh reported.
What is wavefront optimized lasik?
Wavefront-optimized LASIK is a conventional procedure with the added benefit of a built-in correction for spherical aberration. The laser algorithm is optimized by factoring in the population average for spherical aberration from a data set of wavefront exams. By attempting to counter this average induced spherical aberration and maintain the natural prolate shape of the cornea, optimization does improve upon conventional treatments. However, the treatment that is delivered is still phoropter-based. It has nothing to do with the individual patient’s preoperative wavefront or actual induced spherical aberration, so in patients with significantly more or less spherical aberration than average, an optimized procedure may be less beneficial.
What is the correct manifest refraction for lasik?
These treatments are based on a subjective, phoropter-derived manifest refraction. The surgeon determines the correct manifest refraction is –3 D and plugs that into the laser to perform a –3 D myopic correction. Some physicians make nomogram adjustments to account for the fact that the excimer lasers were originally designed to perform PRK. Conventional treatments, because they are based on the phoropter, are limited to 0.25 D increments, making them somewhat imprecise. We can correct 3 D, 3.25 D, 3.5 D or 3.75 D, but not 3.36 D, for example.
What is topography integrated wavefront guided lasik?
Topography-integrated wavefront-guided LASIK relies on a high-resolution aberrometer to objectively measure refractive error and calculate the treatment based on the custom wavefront. In addition, coaxially obtained keratometry and topography measurements influence the pulses, particularly to prevent the cosine effect, which can otherwise reduce the effectiveness of laser pulses to the periphery.
How does topography guide lasik?
Topography-guided LASIK combines custom and conventional approaches. Topographical information determines where to deliver the pulses to smooth out irregularities and homogenize the corneal surface, but the refractive error correction is determined by the manifest refraction from the phoropter. The rationale for topography-guided LASIK is that it makes sense to correct only the corneal aberrations on the cornea; aberrations from the lens or other internal structures might change over time and should not be changed on the cornea. The challenge is that the topography-correcting pulses influence the refraction, so additional calculations are required to avoid overcorrection or undercorrection.
Why are excimer lasers limited to 0.25 D?
Conventional treatments, because they are based on the phoropter, are limited to 0.25 D increments, making them somewhat imprecise.
Is Smile a LASIK procedure?
Small-incision lenticule extraction is not a LASIK procedure. In SMILE, the cornea is reshaped by removing a lenticule of tissue rather than ablating tissue. In the U.S., SMILE can be used to treat myopia and astigmatism, but not hyperopia. Figure 2.
Is lasik a successful procedure?
LASIK has been a successful procedure now for many years. The basic steps of the procedure, including a femtosecond lamellar flap and excimer laser ablation, are well understood. However, there is still a lot of confusion out there among patients — and, frankly, clinicians — about the terminology we use to describe the various LASIK platforms ...
How is wavefront lasik different from conventional lasik?
Wavefront LASIK is different from conventional LASIK because of the way the eye is measured for the procedure. Conventional LASIK required the surgeon to objectively measure the eye with handheld instruments or an automated device. These measurements were then applied to the entire reshaping process. The deficiency in this system is that the eye is not uniform so applying the same measurement was not the best option and resulted in less than ideal results for the patient.
What is Wavefront LASIK?
Wavefront LASIK is the latest in LASIK technology and has helped to correct the deficiencies of conventional procedures. The Wavefront mapping of the eye makes the LASIK procedure more accurate and reduces the side effects that had been seen with conventional LASIK. Eye Michigan offers the same technology that is referred to as Wavefront tech in that of their Wavelight Allegretto Laser, which offers some of the most precise LASIK eye Surgery in the Metro Detroit area.
How accurate is wavefront lasik?
Wavefront technology takes a waveprint of the entire eye’s optical system. This system is considerably more accurate than conventional methods and takes hundreds of data points over the entire eye. By taking measurements over the entire eye a map for the LASIK procedure is developed so that the surgery will be more precise. During the procedure the wavescan instrument will monitor and record each correction as it takes place and prevent unnecessary changes from being made. This type of monitoring during the procedure was not possible with conventional LASIK.
What is a laser assisted in situ keratomileusis?
LASIK or laser assisted in situ keratomileusis is a procedure that uses two types of lasers to access and reshape the cornea of the eye. The result of this procedure is an improvement in many eye conditions that cause vision to be blurry. The procedure has been around since the 1980s and continues to evolve as doctors learn more. The latest in LASIK technology is Wavefront LASIK.
CUSTOM LASIK
Custom LASIK, on the other hand, is a bit more complex with its procedure. The procedure follows much of the small principles of LASIK, including making a flap on the cornea.
iDesign
Out of the options we have discussed before, iDesign is most definitely the most expensive of the bunch. Much like Custom LASIK, advanced technology is utilized in order to scan the eye and map it out. However, this tech, in particular, is more precise than its counterpart.
