To improve the results and safety of your refractive procedure, Dr. Lin has helped develop a technique called, “MICRO-LASIK”. He has performed over 30,000 procedures using the MICRO-LASIK® technique and has published and lectured on this technique nationally and internationally.
Typically used to treat:
· Higher prescription Myopia
· Patients with thin corneas
What is Micro-LASIK®?
Micro-LASIK® is one of the options used to create the corneal flap in Step 1 of the LASIK Procedure to gain access to the corneal stroma.
Stage 1: Accessing the corneal stroma
· Micro-LASIK®– specially designed technique that creates a flap, using a Microkeratome, which is nearly half the thickness of standard flaps.
Stage 2: Laser Treatment
Stage 3: Closing Stage
Micro-LASIK® is a corneal-flap-creating-LASIK-technique that creates a corneal flap that is almost 50% thinner than flaps that are created using other microkeratomes. Micro-LASIK® utilizes a specially-designed microkeratome to create a 100 micron flap, preserving more corneal tissue, which allows IQ Laser Vision to correct higher prescription of myopia with much greater results.
How does Micro-LASIK® work?
As one of the options for “Stage 1: Accessing the corneal stroma” in the LASIK procedure, Micro-LASIK® is a technique used to gain access to the corneal stroma. The Micro-LASIK® technique doesn’t differ much, in its process, from standard LASIK flap creations. The difference is that it uses a special microkeratome that creates a flap that is 100 microns thick versus the standard 180 microns. The flap is gently created and the corneal stroma is revealed for the laser to treat to correct your vision.
The thinner flap, created using the Micro-LASIK® technique, decreases the risks involved with the procedure, increases the quality of the outcome, and decreases the recovery time.
What are the benefits of Micro-LASIK®?
· Increased cornea strength and stability
· Increase the quality of procedure outcome
· Decrease risks and side effects – dry eyes; halos; cornea ectasia
· Decrease recovery time
With MICRO-LASIK®, corneal flaps are almost 50% thinner than flaps created by other microkeratomes.
A thinner flap means there is more corneal tissue under the flap to give the cornea more strength and stability. The extra corneal tissue available with MICRO-LASIK® allows Dr. Lin greater flexibility in treating your eyes, and can reduce side effects such as halos, cornea ectasia and dry eyes. Patients will benefit from this extra margin of safety, especially those patients with larger pupils and higher refractive errors, because more corneal tissue needs to be treated. The thinner corneal flap also decreases recovery time because the natural bandage can heal much faster than with a thicker flap. Dr. Lin’s MICRO-LASIK® technique results are superior to most published LASIK results.
For example, if you came in for your ‘Free Consultation,’ and your cornea was measured to be 520 microns thick.
520 μm original tissue
The traditional LASIK technique will create a 180 micron flap
(see image above)
Micro-LASIK® creates a 100 micron flap (see image above)
Traditional = 180 μm flap
Micro-LASIK® = 100 μm flap
Based on your current prescription 100 microns of your cornea will need to be treated with the laser in order to reshape the curvature of your cornea.
100 μm of treatment
RESULT (residual tissue):
240 μm = Traditional
320 μm = Micro-LASIK®
520 μm – 180 μm - 100 μm =240 μm
520 μm – 100 μm - 100 μm =320 μm
When the pupil is large, a larger optical zone should be used to decrease glare and halos at night. Therefore, more corneal tissue will be removed. Currently most surgeons agree that the residual cornea should be at least 250 to 300 microns (µm=1/1000th mm). With LASIK a 180 micron flap is usually created so we are unable to safely utilize the 6.5mm optical zone. With MICRO-LASIK®, a 100 micron flap is created, so we are able to use a 6.5mm optical zone. More residual cornea is available to give the cornea strength after reducing side effects using MICRO-LASIK®
Who is a candidate for Micro-LASIK®?
Good candidates for the Micro-LASIK® technique include patients who:
· Individuals who are over 18 years old
· Have healthy corneas and no major vision-related issues
· Stable vision – No significant change in their vision within the past 12 months prior to the procedure
· Patients who use glasses or contact lenses to improve their vision are ideal candidates
There may be times when IQ Laser Vision may need to turn away patients because they are not a good candidate for the procedure because our number one concern is not the number of patients we bring in but the quality of care and high level of service we provide. That is why it is important to come in for our FREE CONSULTATION, in order for IQ Laser Vision to determine your candidacy and provide the best vision correction options for you.
What can you expect with Micro-LASIK®?
With the Micro-LASIK® technique, like LASIK, our goal is to eliminate, if not reduce, your dependency on corrective lenses. The benefit of the Micro-LASIK technique is that you increase the positive results of your LASIK procedure. The technique retains more residual cornea tissue and reduces the risk of potential side effects of LASIK, such as halos.
What are the risks of Micro-LASIK®?
Micro-LASIK® does not increase risks associated with LASIK correction. The risks associated with Micro-LASIK® are the same as with any standard LASIK procedure. Some potential risks may include:
· Dry eyes
· Halos (typically at night)
· Variations in recovery time – nutrition, adherence to IQLV recovery guidelines, and activity level are some factors that may have an effect on recovery time
· Genetic variations – age, gender, ethnic background, family health history – these may have effects
· Corneal abrasion – in very rare cases
All risks are discussed and addressed before, during and after the procedure. IQ Laser Vision is dedicated to answering any and all questions you may have to ensure complete conformability and proper expectations with the procedure.
FAQs about Micro-LASIK®
Q: What are the odds of no longer needing glasses for distance with the laser procedure?
A: Studies have shown that nearly every patient experiences a marked improvement in their vision as compared to their previously uncorrected vision with glasses or contacts. Over 99% of patients will attain corrected vision that will meet or exceed the DMV licensing requirements.
Q: Will I experience any pain with this procedure?
A: Every effort is made to ensure that our patients have a very comfortable experience during and after their procedure. Most patients experience no pain and are able to return to their routine activities the following day. You may feel some slight pressure, but should not experience any pain.
Q: I am over age forty. Will laser vision correction eliminate my need for distance and reading glasses?
A: Laser procedures are very effective in correcting myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. These disorders are a result of a corneal curvature that is either too steep or too flat for the length of the eye. Vision is improved when the laser reshapes the curvature of the cornea. After reaching the age of forty most people experience a decline in the quality of their reading vision. This problem is age related and is due to a weakness of the focusing mechanism of the lens of the eye. Although laser vision correction cannot directly correct this problem, LASIK can give good distance and reading vision to many patients by readjusting the focus of their eyes. During your consultation, we will let you experience what you can expect after your procedure.
Q: If I have LASIK and my vision changes later in life, what can be done?
A: Once you eyes have stabilized after surgery, the correction is permanent. In the rare event that your vision does change, re-treatment is a possible option. We would perform a thorough examination and ensure adequate corneal thickness is present before any further correction.
Q: Are there any long-term side effect of LASIK?
A: Over 17 million people, including Dr. Lin, have had LASIK over the last 20 years. Refractive surgeons have been performing a similar procedure for over 50 years, a procedure known as automated lamellar keratoplasty (ALK). There have been a few reports of the cornea becoming unstable years after the procedure is performed. These cases are very rare, and occur mostly in cases where the stromal bed is below 250 microns (0.25mm). When I perform the LASIK procedure, I measure the corneal thickness during the surgery to ensure that we leave at least 280 microns in the stromal bed. With the MICRO-LASIK thin flap LASIK technique we often have more than 360 microns in the stromal bed. We can discuss this and any other concerns you may have at your consultation.
Q: How long does the eye take to heal after surgery?
A: The cornea is about 90% healed in the first 24 hours after the LASIK procedure. You can resume full activity after two weeks. However, there will be continuous healing for 3-6 months.
Q: Will I have perfect 20/20 vision after having LASIK?
A: This depends on your best correctable visual acuity. Some of our patients achieve better than 20/20 vision! Most patients achieve their full desired visual acuity. If the desired visual acuity is not achieved, an enhancement procedure is usually performed three months after the initial procedure.
Q: What will I see during the procedure?
A: During the procedure, we will ask you to focus on a blurry, blinking red light. Immediately after the procedure the red light should become much clearer, and you should notice an improvement in your vision.
Q: I am very concerned about being able to remain still during the procedure?
A: This is a common fear many patients have. Since every patient moves during the procedure, the laser treatment is designed to stop instantly if necessary. Our lasers, the Alcon Nidek EC-5000 and the Alegretto WaveLight Eye-Q 400Hz, have eye trackers that will follow your eye during the procedure. The laser delivers the pulses wherever they are supposed to go, despite any eye movements.
Q: What if I blink during the procedure?
A: To minimize blinking, your eye will be numbed by an aesthetic. Even if you blink, the eye is held open by a small device called speculum, a minimal discomfort, and the Eye Tracker will still track your eyes to ensure proper laser placement.
Q: Will I need to wear anything over my eye(s) after the procedure?
A: Patients will wear a clear shield immediately after the procedure and during sleeping hours.
Q: Will I have any scars?
A: The minimal scarring that occurs will be out of the visual axis (will not affect vision) and can only be seen with a microscope.
Q: In the event that I am not fully corrected, can I still wear contact lenses?
A: Yes, in almost all cases, you will be able to wear contacts after the procedure. However, it is rare for patients to wear contact lenses, except cosmetic colored contact lenses.
Q: Who is a good candidate for LASIK?
A: In general, patients who see well with glasses or contact lenses, have healthy eyes and are in good health are good candidates for laser vision correction. Whether or not you should undergo the procedure is a decision that should be made after a comprehensive exam by a skilled ophthalmologist who specializes in laser vision correction. Our exams are part of a no-cost consultation that will allow the patient and surgeon to discuss all options available.
Q: Is LASIK safe?
A: Laser vision correction is very safe, when performed by a skilled surgeon. Dr. Lin, himself, had LASIK over 15 years ago. He has performed over 30,000 refractive procedures, and has performed MICRO-LASIK® on his parents, and two brothers, one who is a doctor, and the other a lawyer. Dr. Robert Lin is a nationally known, and well-respected surgeon who operates with his patients’ safety as the top priority. Most complications can be treated with eye drops or a repeat procedure. More serious complications are rare because the procedure is limited to the front surface of the eye and not in the eye itself. There have been no reports of blindness caused by LASIK and none of Dr. Lin’s patients have lost significant vision. Without glasses or contacts lenses all of Dr. Lin’s patients have had improved near or distant vision. Dr. Lin and our staff will thoroughly discuss any risks and benefits before the surgery
Q: What takes place during a complimentary consultation at IQ Laser Vision?
A: At the FREE consultation, we will gather data about your eyes including: visual acuity, refraction, measurement of current glasses, biomicroscopy, infrared pupillometry (measurement of nighttime pupil size), pachymetry (measurement of corneal thickness), corneal topography (using up to 3 different systems to measure both anterior and posterior surfaces), and if applicable, wavefront analysis. Based on these findings, our surgeon, Dr. Robert Lin will select the best treatment for your eyes. He will take as much time as necessary to thoroughly understand your expectations and explain the risks and benefits of the procedure.
