Lens Implant

What are Lens Implants?

Phakic Intraocular Lenses are prescribed in cases where a patient is either not a suitable candidate for Lasik surgery, or has a refractive error that is too large to be corrected with laser surgery, or cannot be corrected with laser surgery alone. In these cases a lens is implanted in order to provide the extra lens power the eye needs to focus an image on the retina of the eye.

Spherical refractive errors (myopia and hyperopia), as well as astigmatism (with or without myopia/hyperopia) can be treated by Phakic Intraocular Lenses.

Unlike Lasik surgery, the cornea is not modified in any way, but rather the refractive properties of the eye are changed by the lens itself. Phakic lenses also provide a wide optical zone which is beneficial for low light vision.

The Procedure

This specific type of refractive eye surgery involves the permanent implantation of a lens either in the anterior or posterior chamber of the eye. Various lenses suit various conditions and after a consultation with your doctor he will determine which lens is suitable for your vision correction.

The procedure is performed on one eye at a time, and can be performed under either local or general anaesthetic, depending on what your surgeon deems most suitable.

Post-operative check-ups and hygiene are imperative.

Should I do it?

Candidates for Vision Correction surgery are typically people who are unhappy wearing spectacles or contact lenses, or those who have an extreme visual disability, and want to wear a more comfortable, thin-lens spectacle.

If you are over 20 years of age and have not had any significant change in your vision (or spectacle prescription) over the preceding 2 years, then you will most likely be able to have the surgery.

This is a long term solution that has had very favourable results on thousands of patients around the world.
