I love travelling and the tropics are one of my favourite destinations. Great food, bath tub warm seas and beautiful beaches. However travellers wearing contact lenses should be extra careful in tropical climes. The warmth and humidity are great environments for fungi, amoebi and bacteria to flourish, and a contact lens related infective ulcer can bring a rapid end to your holiday and worse still, permanent loss of vision in some cases.
Laser eye surgery has until now been an irreversible procedure. A year long experimental project I undertook whilst in Singapore, now published in the scientific journal PLos One, describes our pioneering, innovative work on developing a reversible type of laser eye surgery. The technique is based on a new type of laser procedure called ReLEx performed with the Visumax femtosecond laser.

The light from distant stars is distorted and bent as it travels through space to reach us on earth. Astronomers use a technology called wavefront analysis to measure and compensate for these changes in the light path as it travels through the universe to allow them to see the stars in their undistorted true form. This technology is now used during laser eye surgery to detect any aberrations or distortions in the optical system of the eye. These measurements go beyond a simple vision correction based on your glasses to refine and optimise the optics of the eye. Wavefront guided and wavefront optimised custom LASIK/LASEK laser vision correction gives the best possible quality of vision by attempting to correct all aberration within the visual system.
Scientific discovery is far reaching and mans quest to understand the heavens means that laser vision surgery is better than ever before.

Did you know that the US military has been performing laser eye surgery on frontline personnel for over a decade?
However, it's not LASIK, but LASEK and PRK that is performed on military personnel likely to see active war zone duty. Many large studies have shown that surface procedures such as LASEK and PRK give the same excellent visual results as the more popular LASIK procedure.
So why not LASIK if your a elite Navy SEAL? The first step of LASIK involves making a precise flap in the cornea, which allows the vision correction laser to be applied beneath the flap. If you're in a profession where you're likely to suffer facial trauma (as in a war zone) this flap can be dislodged resulting in temporary loss of vision. Clearly, not ideal if you're in the middle of a gun battle! Surface procedures such as LASEK and PRK don't have a flap. The laser is applied directly onto the surface of the eye, which then heals over.
If you're in the military, police, or like full contact or extreme sports, your doctor may recommend LASEK or PRK rather than LASIK. You can be reassured that these procedures have been tested in some of the toughest theatres of war around the world.
LASEK and PRK also disturbs less corneal tissue than LASIK and your doctor may recommend this of you have thin corneas. The results are exellent with all these techniques.
Contact lenses give great vision to many people, but as a corneal specialist I see many patients with corneal ulcers caused by poor lens wear. It is essential to follow strict hygiene when wearing contact lenses. Always wash your hands before handling your lenses, and never wash your lens or its case in tap water. Tap water in the UK can contain an organism called Acanthamoeba, which can cause devastating corneal infections and permanent visual loss. For this reason you should avoid splashing shower water into your eyes if you're wearing your lenses during a shower. Swimming with contact lenses either in your local pool or the sea is a definite no no!
Whilst patients are often hygienic with their lenses, they often forget that the contact lens case is a reservoir for bugs. So, if you wear monthly disposible lenses make sure you change the container each month too. Sleeping with lenses in deprives the cornea of oxygen and increases risk of infection.
As a rule, if your eyes are red, feel uncomfortable, or have a discharge, dont wear lenses till they feel back to normal. And if you dont like the hassle of lens wear and their inherent risks and costs, there's always glasses or LASIK.

JT's new album cover titled 'The 20:20 Experience' shows the singer in a dinner jacket standing behind a phoropter, a common ophthalmic instrument used to measure the power of peoples glasses. Whilst the cover photo and title of the album are a laser eye surgeons idea of dream celebrity marketing. The album has received mixed reviews

Mr Angunawela was recently interviewed by Askimo TV, an internet 'TV station' that interviews experts around the world on various subjects. He was asked some common questions about laser eye surgery.
