Surgical Vision Correction

There are several surgical and laser options for the correction of short sight, long sight and astigmatism. Although no single vision correction procedure will be suitable for all eyes.

Unlike some centres which may offer only excimer laser treatment or only non-laser surgical options, our ophthalmic surgeons can offer a wide range of both laser and surgical treatments. This means that we can consider treating all degrees of short and long sight with or without astigmatism.

Before deciding upon which may be the best treatment option for your eyes it is important for you to have a thorough eye examination. Our experienced ophthalmic surgeons can then discuss with you the procedures that may be suitable for the correction of your sight.

You may consider our Treatment Guide for your possible treatment options.

If an individual has signs suggestive of early cataract development then it may be more appropriate to perform a lens extraction and intraocular implant regardless of the refractive error. For details see Refractive Lens Exchange.

Refractive Lens Exchange

Refractive Lens Exchange is exactly the same procedure as carried out with a cataract extraction together with the insertion of an intraocular implant, except that the removed lens has no cataract and is therefore clear.

The power of the implant to be inserted is calculated to give as close a final prescription to zero as possible, thereby correcting the underlying refractive error.

The AKKOMMODATIVE® 1CU represents the latest development in artificial lenses and can provide patients with a better quality of life. The lens is designed to change shape providing a similar function to that of your natural healthy lens.

The AKKOMMODATIVE® 1CU lens gives most patients the ability to perform normal daily life activities without the need for glasses or contact lenses. Unlike traditional artificial lenses, distance and near objects can both be seen in focus without spectacles.

Phakic Implants

Phakic implants are similar to the implants inserted after cataract or refractive lens exchange, however, the persons own lens is not removed but augmented with the addition of a synthetic intraocular implant.

They are of three main types. One, the implantable contact lens (ICL) is placed behind the iris, whilst the other two types are positioned in front of the iris.

Phakic implants are a relatively new development in refractive surgery and can be used for patients unable to be treated with LASIK, particularly those with very high degrees of short sight.

Astigmatic Keratotomy

In astigmatism the corneal shape is not symmetrical. It tends to be steeper in one direction (like a rugby ball).

Astigmatic Keratotomy consists of making relaxing incisions into the mid-periphery of the cornea, these relaxing incisions allow the steep axis to flatten and improve the overall corneal shape.

For some individuals who have astigmatism without any other significant refractive error this procedure may improve their unaided vision.

It may also be used as an adjunctive treatment to other forms of laser or surgical vision correction where there are high degrees of astigmatism.

Intrastromal corneal ring segments (Intacs) are an exciting new way to achieve vision correction for short sight by reshaping the cornea using tiny, virtually invisible segments.

Unlike other forms of refractive surgery, Intacs intrastromal corneal ring segments offer the potential for permanent vision correction but without permanently altering the central optical zone of the eye.

There are many benefits associated with vision correction. The benefit one receives depends mainly on the person and their visual requirements.

Some of the potential benefits include:

All forms of surgery carry some degree of risk and complications are possible. On the whole refractive surgery enjoys a high safety record, it is however an elective procedure and there are certain potential complications and risks you should be aware of before considering treatment.

Our patient information brochure outlines the potential complications and risks in greater detail. The complications will be discussed in-depth at your assessment consultation.

All forms of Surgery have associated risks and complications.
