LASIK with the Technolas ACE Eye Tracker

Beverly Hills, Rancho Cucamonga, Burbank

from Technolas Perfect Vision.

No other LASIK system available in the US can compensate for eye rotation during the LASIK treatment. Both the Technolas ACE and VISX S4 IR (Abbot Medical Optics, Santa Ana, CA) trackers compensate for the cyclorotation of the eye that can occur between the sitting position during critical diagnostic measurements and lying down on the LASIK bed. However, only the Technolas ACE tracker can adjust the delivery of laser pulses in response to eye rotation during the LASIK treatment. Further, the Technolas ACE system is enabled for both conventional and custom wavefront-guided LASIK treatments, while the VISX S4 IR tracker cannot adjust for cyclotorsion associated with conventional LASIK treatments.

The eyetrackers of the Wavelight and Ladarvision lasers (Alcon Laboratories, Fort Worth, TX) cannot compensate for eye rotation at all. The Wavelight system employs a four-point LED illumination pattern that the patient views, known as NeuroTrack™, which the company claims prevents any rotation during the procedure; however, no clinical data is available to confirm that this is indeed the case. In fact, a recent large study by Emory University using the Wavelight laser demonstrated that astigmatic eyes were nearly twice as likely as non-astigmatic eyes to require a touch up or enhancement procedure following LASIK. Increased enhancement rates among astigmatic eyes could be indicative of eye rotation during the treatment that goes unchecked.

This new eyetracker also doubles the speed of tracking so as to allow the laser to rapidly adjust to the eye’s movements; response time with ACE is now under 7 milliseconds, or 0.007 seconds. ACE also adjusts for the pupil center shifting that can occur between light and dark settings, critical to the proper centering of customized LASIK treatments over the pupil.

To find out more about how this system works, and to learn more about LASIK eye surgery, join us for a free consultation! Sit down with Dr. Vishteh to determine if LASIK is right for you. We’re available toll-free at (888) 514-2020.

Cataract Surgery

Beverly Hills, Rancho Cucamonga, Burbank

from The Foundation of the American Academy of Ophthtalmology

What is a cataract?

A cataract is a clouding of the eye’s naturally clear lens. The lens focuses light rays on the retina—the layer of light-sensing cells lining the back of the eye—to produce a sharp image of what we see. When the lens becomes cloudy, light rays cannot pass through it easily, and vision is blurred.

What causes cataracts?

Cataract development is a normal process of aging, but cataracts also develop from eye injuries, certain diseases, medications, or long-term exposure to sunlight. Your genes may also play a role in cataract development.

How can a cataract be treated?

A cataract may not need to be treated if your vision is only slightly blurry. Simply changing your eyeglass prescription may help to improve your vision for a while.

There are no medications, eyedrops, exercises, or glasses that will cause cataracts to disappear or to prevent them from forming. Surgery is the only way to remove a cataract. When you are no longer able to see well enough to do the things you like to do, cataract surgery should be considered.

In cataract surgery, the cloudy lens is removed from the eye through a surgical incision. In most cases, the natural lens is replaced with a permanent intraocular lens (IOL) implant.

What can I expect if I decide to have cataract surgery?

Before Surgery

To determine if your cataract should be removed, your ophthalmologist (Eye M.D.) will perform a thorough eye examination. Before surgery, your eye will be measured to determine the proper power of the intraocular lens that will be placed in your eye. Ask your ophthalmologist if you should continue taking your usual medications before surgery. You should make arrangements to have someone drive you home after surgery.

The Day of Surgery

Surgery is usually done on an outpatient basis, either in a hospital or an ambulatory surgery center. You may be asked to skip breakfast, depending on the time of your surgery.

When you arrive for surgery, you will be given eyedrops and perhaps a mild sedative to help make you comfortable. A local anesthetic will numb your eye. The skin around your eye will be thoroughly cleansed, and sterile coverings will be placed around your head. You may see light and movement, but you will not be able to see the surgery while it is happening.

Under an operating microscope, a small incision is made in the eye. In most cataract surgeries, tiny surgical instruments are used to break apart and remove the cloudy lens from the eye. The back membrane of the lens (called the posterior capsule) is usually left in place.

A plastic, acrylic, or silicone intraocular lens is implanted in the eye to replace the natural lens that was removed. After surgery is completed, your doctor may place a shield over your eye. After a short stay in the outpatient recovery area, you will be ready to go home.

Following Surgery

You will need to:

  • use the eyedrops as prescribed;
  • be careful not to rub or press on your eye;
  • avoid strenuous activities until your ophthalmologist tells you to resume them;
  • ask your doctor when you can begin driving;
  • wear eyeglasses or an eye shield, as advised by your doctor.

You can continue most normal daily activities. Over-the-counter pain medicine may be used, if necessary.

Is a laser used during cataract surgery?

Lasers are not used in cataract removal surgery. However, the lens capsule (the part of the eye that holds the lens in place) sometimes becomes cloudy several months or years after the original cataract operation. If the cloudy capsule blurs your vision, your ophthalmologist can perform a second procedure using a laser. This procedure, called a posterior capsulotomy, uses a laser to make an opening in the cloudy lens capsule, restoring normal vision.

Will cataract surgery improve my vision?

The success rate of cataract surgery is excellent. Improved vision is achieved in the majority of patients if other vision-limiting problems are not present.

Complications after cataract surgery

Though they rarely occur, serious complications of cataract surgery are:

  • infection;
  • bleeding;
  • swelling; and
  • detachment of the retina.

Call your ophthalmologist immediately if you have any of the following symptoms after surgery:

  • pain not relieved by nonprescription pain medication;
  • loss of vision;
  • nausea, vomiting, or excessive coughing;
  • injury to the eye.

Even if cataract surgery is successful, some patients may not see as well as they would like to. Other eye problems such as macular degeneration (aging of the retina), glaucoma, or diabetic retinopathy may limit vision after surgery. Even with these problems, cataract surgery may still be worthwhile. Talk to your ophthalmologist to learn more about cataract surgery and its risks and benefits.

10 Key Facts about LASIK

Beverly Hills, Rancho Cucamonga, Burbank

From: WebMD

You can hardly turn on the TV or the radio without hearing ads about a new, low-cost eye surgery to rid you of those bothersome glasses or contacts. But how can you be sure you’re not playing Russian roulette with your eyes?

WebMD Health professional Bill Lloyd, MD, is a board-certified ophthalmologist qualified to perform laser refractive surgery. LASIK is one of the most frequently performed operations in America. In order to shed some light on this very popular surgery, Lloyd outlines ten important things to know before undergoing laser refractive surgery.


1. Know Yourself — Why do you really want to have this surgery? You will live with its results forever, so don’t be caught up in a fad. There are no guarantees. Many LASIK patients are still wearing glasses!

2. Know Your Surgeon — Look for an experienced, board-certified ophthalmologist. Ask direct questions regarding your surgeon’s experience and complication rate. Will your surgeon continue to take care of you after the surgery, after surgery, or will you be redirected to a non-physician?

3. Know Your Refractive Error — The more nearsighted (myopic) you are, the more likely you may need a repeat procedure (euphemistically called “refinements”). Ask your doctor what the chances are that you’ll need a refinement.

Continue reading below…

4. Know if You Are Eligible — LASIK is not for everyone. People with severe dry eyes, certain corneal diseases, and other select eye conditions should not undergo LASIK.

5. Know What Happens — Be sure you fully understand the entire procedure. Since you will be awake for the surgery, you don’t want any surprises.

6. Know the Odds — After laser refractive surgery, most patients enjoy improved (not necessarily perfect) vision without their old glasses. Nobody guarantees 20/20, 20/25, or 20/30 vision. If you hear such claims, consider looking elsewhere.

7. Know the Risks — Laser refractive surgery is surgery. There is no such thing as “minor eye surgery.” Complications such as overcorrection, undercorrection, making the pupil off center, damaging the cornea, inflammation, and infection can leave you miserable. You may hear statistics about 2% or 5% complications, but if it happens to you, it’s 100%!

8. Know the Limitations — LASIK is used to help correct nearsightedness and astigmatism. Laser refractive surgery will not prevent you from needing reading glasses as you approach middle age. There may be future advancement but, as of this writing, LASIK patients will need help to read later in life just like their parents did.

The majority of people with mild or moderate nearsightedness can expect to have uncorrected vision (without glasses or contacts) of 20/40 or better after LASIK surgery. Some may have 20/20 vision or better. Good results are less certain with more severe nearsightedness.

9. Know Your Postsurgical Care — Be sure both you and your partner understand the postoperative eye-drop routine. Since these medications influence corneal healing, your final visual outcome will depend heavily on the correct use of your eye drops. Make sure you find out what kind of care you will receive after the surgery and how often your doctor will want to see you. Be sure to ask about any limitations you may have after surgery, such as sports or makeup.

10. Know About Alternatives — Alphabet soup! LASIK, LASEK, PRK, INTACS, and many more. Don’t hesitate to ask your surgeon, “Is this the very best way to treat my situation? Are there other methods?” Experienced eye surgeons typically know three or four ways to manage the same patient. Carefully weigh any decision to participate in any innovative research trials. It’s hard to beat solid experience!



Beverly Hills, Rancho Cucamonga, Burbank

Frequently Asked Questions:

How much does LASIK/PRK cost?

Your LASIK counselor will go over pricing as well as discuss any applicable discounts with you when you meet at the end of your consultation.

Can I finance my procedure?

We do not offer in-house financing at this time, but have a number of financing options available through CareCredit. Applying is quick and simple and can be done over the phone by calling (800) 365-8295 or online at carcredit.com/apply. Just provide a little information about yourself and your income and you’ll get an instant decision. We can even apply for you at your consultation if you have two forms of ID!

Where will my procedure take place?

Right here in our Rancho Cucamonga office, ask for a tour!

Will I be able to drive myself home after my procedure?

No. Since you are undergoing a procedure on your eyes, your vision will be impaired immediately afterwards. Additionally, we provide a mild anxyiolytic to ensure that you are calm and comfortable during your procedure, so it would not be safe or recommended to operate a motor vehicle under those conditions.

Can I bring my friends or family to watch my procedure?

Absolutely! We have a private viewing corner where your friends and family can watch your procedure on a TV monitor.

Does LASIK/PRK hurt?

Patients sometimes report an uncomfortable sensation of pressure during LASIK or a mild stinging sensation during PRK. Dr. Vishteh will discuss all the risks and benefits with you at your consultation.

How long will my procedure last?

Expect to be in the office for 1-1 ½ hours on surgery day. You will be in the operating room for about 10-15 minutes and the laser itself will only run for about 10-30 seconds per eye, depending on your level of treatment. The actual procedure itself is incredibly quick, it’s the prep-work (readying the instruments, calibrating the laser, double- and triple-checking our treatment numbers) that take up most of that time.

How long will my treatment last?

LASIK/PRK is not reversible, the corrections made to your eye are permanent. Adjustments can be made, when deemed safe and necessary by your surgeon, to ensure that you are satisfied with your level of correction even if it’s years down the line!

What if I wear contacts?

You may attend your consultation if you currently wear contacts, and even wear them to your consultation if you’re not able to or comfortable with removing them beforehand. We have lens solution and disposable contact lens cases on hand so that you may remove them in-office to complete your exam. It is necessary, however, that you discontinue wear of your contacts immediately prior to both the dilated exam and your surgery, as determined by your surgeon.

Can I go home and watch TV after my surgery?

No. For the first 4-6 hours of your recovery after surgery, it is imperative that you rest your eyes as they begin to heal. After about 20-30 minutes from

What if I move during surgery or blink?

You can’t! During the procedure, the operative eye is held gently open with an instrument called a “speculum.” You are also positioned in a special headrest to help you remain still. We also have a new ACE Eye Tracker software in place to track any movement of your eye by using your pre-operative iris-registration photos. This means that we lock onto your eyes before the laser runs and track and follow any movement they make. If your eye moves out of range, the laser ceases firing immediately!

What to Expect from Your Consultation

Beverly Hills, Rancho Cucamonga, Burbank

Thank you for considering us for your laser vision correction. Here at Rancho Laser Vision Center, we pride ourselves on our level of patient care. We understand that trusting someone with your eyes is a lot to ask and it is very important to us that we ensure that our patients are happy and comfortable. We know how scary it can be to visit a doctor, let alone one who could be operating on you! That is why Dr. Vishteh makes it a priority to meet all of his patients and evaluate them personally. Not only will he assess your candidacy for surgery, but he will also be sure to thoroughly explain the LASIK/PRK process and all of your options to find the treatment that is right for you.




Your appointment will take place at one of our three offices in Beverly Hills, Burbank, or Rancho Cucamonga. Dr. Vishteh divides his time between these locations so that he can meet with, treat, and follow-up with his wide patient base. We have appointments available throughout the week as well as one Saturday a month for your convenience.


When you check in, you will complete a brief questionnaire explaining a little bit about yourself; how you came to find us, your medical and ocular history, and what you hope to gain from your treatment with Dr. Vishteh. After completing this form, you’ll watch an introductory video that offers some basic information about the procedure and will hopefully answer some questions you may have before we get started with your exam.


Your exam will consist of three parts: first, the work-up; second, a thorough examination by Dr. Vishteh; and last, a closed meeting with your LASIK counselor. During your work-up, your ophthalmic technician will conduct a series of tests to help determine your candidacy including an automated refraction and topographical corneal scans. Your tech will also go over your medical and ocular history so that the doctor has a clear and broad understanding of your needs when he meets with you. Dr. Vishteh will join you to complete his exam and review your options with you. At this time you are encouraged to ask as many questions as you like to be certain that you have a clear grasp of both the doctor’s recommendations and your prospects for treatment. After you’ve finished with Dr. Vishteh, you’ll sit down with your LASIK counselor who will explain your pricing and answer any additional questions you may have.



Once you’ve been cleared for surgery, the next step is to schedule your dilated exam and surgery date.


The dilated exam must be completed before your surgery. At that time, we acquire your iris registration photos and custom wavefront-guided readings, followed by a manual and cycloplegic refraction. These tests provide the information that Dr. Vishteh needs to determine your treatment plan and tailor it specifically to you. We will also dilate your pupils so the doctor can perform an internal examination of your eyes to be certain they are healthy inside and out. A word of caution: dilated pupils are very light sensitive and can cause blurry near vision. It is recommended that you be prepared with dark sunglasses (if not, we carry disposable sunglasses that we provide at no charge) and understand that you may not be able to function at full capacity (if, for example, you do a lot of close-up work or fine motor tasks) for the few hours that your pupils will remain dilated. These symptoms are temporary, and will dissipate with time.


Before you are discharged after your dilation, we will provide consent forms for your review and completion. You are encouraged to read these forms in the office in case you have any questions. Your counselor will prepare and review the forms and all that applies to you before you sign them. Afterwards, we will collect your payment (we accept cash, MoneyOrders/Cashier’s Checks made out to Dr. Armin Vishteh, and all major credit/debit cards except American Express). Finally, you will be provided with a written prescription for your post-operative medications to be filled at your pharmacy of choice. If you prefer, we carry the medications in-office and can provide them for a small fee to save you a trip. This is all done at the time of your dilated exam so that you have nothing else to worry about or bring with you on your surgery day!
