Laser Vision Correction - LASIK

Laser-assisted in-situ keratomileusis

LASIK was introduced in the early 1990s. It has become the most widely performed laser method for the correction of refractive errors. Over 10 million successful procedures have been performed worldwide.


Femto LASIK is a bladeless procedure used to create a precise thin flap in the clear front covering of the eye (cornea). The flap is then gently folded back exposing the inner cornea which requires the treatment. An excimer laser reshapes the corneal tissue which corrects the refractive error. The flap is then repositioned and adheres on its own within a few minutes.

WHO Is Suitable?

Good candidates are over the age of 21 with a stable refraction for greater than 12 months

Suitable patients include both myopic (short sighted), hyperopic (far sighted) and patients who have astigmatism

Patients must not be pregnant or breastfeeding

Good vision in glasses or contact lenses

Moderate corneal thickness with a normal

LASIK can treat from +4 to -10 dioptres

What to expect on the day of surgery

Please expect to be in at the facility for 1 hour. This includes pre-operative administration relaxing medication and drops, along with some instructions on what to expect when you are in the laser suite.

It is important to have a friend or family member accompany you on the day. Wear comfortable, warm clothes as the laser room is set at a specific temperature and humidity.

The actual LASIK procedure takes about 10-15 minutes per eye. It will be a pain free experience as topical anaesthetic will be administered to numb the front part of the eye. You will have a special instrument inserted under your eyelids to stop you being able to close the eye.

The doctor will talk to you throughout the procedure with instructions where to look. The Femto - LASIK component will take approximately 20 seconds, to create the flap. The bed will be moved under the excimer laser.

It is common to feel a bit of tugging as the doctor lifts the flap. Once the flap is lifted the laser will be applied to re-shape the tissue this will be quite quick but does depend on the amount of treatment per patient.

Once the treatment is complete the doctor will put the flap back into position and wait about a minute for it to adhere.

The doctor will then apply both an antibiotic and steroid eye drop. You will then be taken to a consulting room where the surgeon will run through instructions and check the position of the flap. It is normal for vision to appear hazy.It is very important not to rub the eye after surgery as it can dislodge the flap. Hard eye shields will be given to wear.

Frequently asked questions

What are the advantages of Femto - LASIK?

The femtosecond laser is fast and highly precise and blade free. This enables the surgeon to quickly and predictably create a hinged corneal flap.

Is it a safe procedure?

Complications during and after LASIK are rare but can’t be completely ruled out. During your consultation the surgeon will discuss these.

Complications can be divided into intra operative and post operative.

Intra operative complications are issues that arise at the time of surgery. These may include incomplete, irregular flaps, “free” flap- the hinge is not preserved and in growth of cells under the flap edge. Flap related complications are very uncommon and are treatable.

Post operative complications may be divided into: post operative over/under correction, regression and can be remedied with re-treatment (enhancement) or mild glasses for the required distance. Dry eye is usually a short-term problem and resolves as the cornea heals. Lubricating drops are given to all patients as some level of dryness is expected. Patients with pre-existing dry eye are at an increased risk of severe dryness post LASIK. Visual changes such as increased glare or haloes may be noticed while driving at night. This is more prevalent in people with high prescriptions or pre-existing night vision problems.

Corneal ectasia can occur when the cornea becomes progressively thinner after a laser procedure and the vision is distorted and blurred. Glasses or contact lenses may be prescribed to correct the vision and Collagen Cross Linking may be performed to halt any progressive thinning.

All efforts are made by your surgeon to screen out any patients who are at a greater risk of this complication. Presbyopia/ age related reading changes affect everyone over the age of 40 to some degree or another. Short sighted people simply take their glasses off to read while normally sighted or long sighted people wear reading glasses. While we cannot halt the natural processes as the eye ages your surgeon may discuss monovision or deliberately leaving one eye a little near sighted to maintain reading vision. This is often trialled with contact lenses prior to surgery to assess your suitability.

How long does the treatment take?

The treatments take between 10-15 minutes per eye.

How do I prepare?

If you wear contact lenses please cease wearing for soft lenses three days before and hard lenses 3 weeks before the procedure.

What should I expect after the procedure?

Avoid eye rubbing. Protective plastic shield will be given to wear to bed. Drops will also be administered to stop post operative infection.

When can I return to normal activities?

Most patients are able to return to work a few days after surgery this includes driving.

When will I see better?

Most patients notice vision is clearer quickly after surgery it is normal to experience some haze initially.
