Laser Vision Correction (incl LASIK)

When light rays pass through the eye, they need to be focused sharply on the retina in order for the image to appear clear and in focus. By re-shaping the front surface of the eye (the cornea) with laser energy, we can correct the eye’s focusing error. LASIK, iLASIK, SMILE, LASEK and ASLA are all laser vision refractive procedures designed to eliminate the need for glasses or contact lenses, by correcting focusing errors of the eye, such as myopia (short-sightedness), hyperopia (long-sightedness) or astigmatism.

Each procedure varies depending on the type of laser used, an individual’s refractive condition and the corneal structure. A detailed assessment and computerised maps of the corneal surface will ensure the best and safest treatment option is recommended to you. The following is a summary of the various techniques used for laser vision correction:

LASIK

A laser is used to precisely create a small flap on the cornea, which is gently lifted by the surgeon. This is immediately followed by a second laser treatment which reshapes the area underneath the corneal flap. The flap is then repositioned. Following the procedure, the vast majority of patients are able to see 20/20, without the need for glasses or contact lenses.

iLASIK

Utilises ‘WaveScan’ technology and ‘Advanced CustomVue’ to perform the LASIK procedure. It allows the treatment procedure to be fully customised for the patient via 3D mapping of their cornea and its focusing errors.

SMILE

Small Incision Lenticule Extraction, also known as ‘keyhole LASIK’ offers laser vision correction for myopia (shortsightedness) in one step. A computer guided laser separates a thin disc (lenticule) of corneal tissue from within the cornea. This lenticule is then removed through a tiny keyhole incision, improving recovery time and comfort, and potentially reducing the incidence of dry eye.

LASEK / ASLA

(Advanced Laser Surface Ablation) / PRK – If your cornea is too thin or your refractive error prevents you being suitable for LASIK, iLASIK or SMILE, these are alternative options. Instead of the corneal flap being created by laser, the most superficial layer of the cornea (epithelium) is manually removed using a rotating brush or with alcohol solution. The underlying corneal tissue is then reshaped with laser.

For those unsuitable for laser vision correction, other techniques such as refractive lens extraction, phakic intraocular lenses and implantable collamer lenses (ICL) are available.

REFRACTIVE LENS EXCHANGE

Eliminates the need for glasses or contact lenses by replacing the eye’s natural lens with a custom intraocular lens, tailored to the individual’s refractive needs. This is a permanent pain-free procedure, with rapid recovery. The procedure is exactly the same as that performed in cataract surgery. However, the natural lens is being removed to achieve a specific refractive outcome rather than removing a cloudy lens (a cataract). Following a refractive lens exchange, you will not require cataract surgery in the future.

PHAKIC INTRAOCULAR LENSES

These are used to treat high degrees of myopia, hyperopia or astigmatism. Through a small incision, an implantable contact lens is placed inside the eye behind the iris and in front of the eye’s natural lens. This implantable contact lens offer spectacle independence, cannot be felt inside the eye, and requires no maintenance. It is also a reversible procedure.
