Laser vision correction

Laser refractive surgery


Z-LASIK is a long-term solution to vision correction. For many people, being free from glasses and contact lenses makes many activities and even daily living much easier. Not having the hassle of contact lenses and glasses makes everything from seeing the alarm clock in the morning to staying up late at night with friends less complicated. Life is fast and busy in the new millennium; Z-LASIK gives you one less thing to worry about. 98% of patients are satisfied with their vision after LASIK.

The Procedure : Z LASIK (STEP 1)

You are given a sedative to help you relax. Anaesthetic drops numb your eyes. You will be lying on a comfortable bed .

Step 2:

The Z LASIK Femtosecond Laser is used to create thousands of tiny bubbles to precisely separate a corneal flap at a specified depth in the cornea.

Step 3:

The flap is then carefully lifted.

Step 4:

The Excimer Laser is used to reshape the cornea, using customised treatment specific to each patient .

Iris recognition technology fixes and tracks alignment of the laser in multiple dimensions. This ensures delivery is absolutely precise and you do not have to worry if your eyes move! (The technology has the added benefit of confirming the correct treatment is being applied to the correct eye!)

Step 5:

When the treatment is complete the flap is replaced and allowed to dry. The flap attaches without the need for stiches and more eye drops are administered to prevent infection and avoid discomfort.

Our eyes are as unique as the rest of our body. Z-LASIK is a premium procedure that takes your unique differences into account. Each Z-LASIK plan is customized to the patient for optimal correction. Astigmatisms and small differences in the surface of the eye are calculated and corrected giving you the best outcome. The following spectacle scripts  are treated :

Short sightedness (Myopia ) : under -6.5
Astigmatism : under -4
Farsightedness (Hyperopia): under +2

If your spectacle refractive error  is higher than the above , there are alternative corrective surgery solutions.  The excimer laser removes tissue with microscopic precision , sculpting the cornea in a pain free procedure.

In general, the following criteria should be met before considering Z-LASIK:

• You are older than 21 years.
• Your vision has been stable for 2 years.
• You don’t have any medical conditions that would inhibit normal healing (auto immune conditions)

Having an allergy to contact lenses  or pre-existing dry eye does not exclude you from considering LASIK. If you are not a candidate for Z-Lasik we will advise you of alternative procedures including PRK.

Frequently Asked Questions (FAQs)

In our practice, LASIK is performed as an outpatient procedure. The entire treatment takes about 5 to 7 minutes per eye or approximately 15 minutes for both eyes.

Yes. Following an initial healing period of two to three months, the effect of the treatment is lifelong.

Generally, patients under 40 years of age read well without glasses following the treatment. Patients over 40 may need magnification for reading fine print. Presbyopia is the term that refers to the natural weakening of the focusing muscles that occurs in our early to mid 40s, causing us to need the magnification that reading glasses provide. The LASIK treatment does not correct or prevent presbyopia. We also will be glad to discuss another option called monovision.

Most patients are usually seen the day following the treatment, at one week, and then at least 1 month and 3 months following the treatment. Some patients require more visits.

You can bathe the same day as the treatment but you should not shower for 2 days after the treatment. As always, avoid getting soap or water directly into your eyes. Avoid rubbing your eyes during the first month after surgery.

You should not drive the day of treatment. After that, you may drive when you feel confident that your visual acuity and eye comfort allow you to drive safely.

You may resume wearing eye makeup starting 1 weeks after your treatment. We strongly recommend that you purchase new eye makeup, specifically mascara, to avoid potential infection following your treatment.

Non-contact sports can be resumed as soon as you feel capable. Eye protection is always recommended for racquet sports or rough sports where there is a risk of being hit in the eye.

You should stay out of swimming pools for one week after your treatment, and rivers, lakes and oceans for two weeks following your treatment.

Numbing eye drops are used. Sometimes an oral medication is used to help with relaxation. Don’t worry -no needles or intravenous drugs are used.

Treatment can be performed on both eyes on the same day. This decreases the troublesome effect of being nearsighted in only one eye between the two treatments. You may elect to have one eye done at a time.

The treatment itself is painless because we put a few numbing drops in your eyes to make you even more comfortable. You will feel pressure on and around the eye during treatment. With LASIK, some patients may experience a feeling of “something in the eye” for a day or so after treatment.

You will be “awake,” but very relaxed. You will not be able to see any of the details of the treatment. You will see a number of lights, but the images will be blurred.

Some patients experience a feeling of burning or scratchiness. This feeling generally lasts from one to three hours following the treatment. Most people feel fine if they can take a nap soon after the treatment.

Each patient is different. The eye drop medications cause some blurring, but most patients notice a dramatic improvement even as they leave the office. More than 4 out of 5 patients can pass a driving test without glasses or contact lenses after the treatment.

No, but clear, protective eye shields will be placed over your treated eye(s) following the treatment, and will be removed in our office the next morning. You will continue to wear these eye shields at bedtime for 1 week for protection.

Most patients are back to work full-time the day after treatment. An additional day or two is rarely required before returning to work. If you can’ we recommend that you take it easy for a couple of days.

The goal of refractive surgery is to reduce your dependence on glasses and/or contact lenses, but LASIK patients still may benefit from reading glasses or distance glasses when they desire perfect near or distance vision. A nominal percentage of patients wear a thin pair of prescription glasses for night driving.

Laser vision correction is an excellent option to correct vision. This results in most patients experiencing a dramatic increase in quality of life, eliminating the need and costs for glasses or contact lenses. Laser correction procedures can often correct common conditions such as farsightedness (hyperopia), near-sightedness (myopia) and astigmatism.
