Non-invasive eye surgery procedures to improve eye sight

Inventive Takes On the Invasive, Surgery May No Longer Be the Only Option

Although laser eye surgery has become a low risk and easy-to-execute procedure, it is still invasive.

Gary Rodney, the Founder of Smart Vision Optometry and a leading Smart Vision Optometrist at Eyes InDesign Mosman, discusses an alternative non-invasive surgery to correct and improve vision.

Many patients do not qualify for eye laser surgery, as they may have irregular corneas, or other conditions, such as inflammation, and bacterial infections often caused by poor hygiene. Additionally many patients are worried about eye surgery given the burning of the inner layers of myopia correction surgery can have permanent negative effects. Many “laser surgeries involve the burning of the matrix of the inner layers of the corneal tissue to flatten and reshape the cornea to correct vision, however this is not always a once-off fix, because the underlying issues of what caused them to become short-sighted in the first place has not been addressed and so the process may need to be repeated and burnt again,” says Rodney.

Laser surgery, such as LASIK, is invasive to the eye and can cause damage or injury to the eye, such as cornea damage, and may cause other complications such as eye infections and permanent dry eyes.

Invasive surgeries are no longer the only option for vision correction, as smart vision optometrists offer non-invasive methods and procedures.

Smart vision optometrists use vision therapy, therapeutic spectacle and contact lenses to improve comfort, enhance performance and optimise visual development.  Visual therapy is a “non-invasive method used to improve and manage different eye conditions,” says Rodney. This technique involves exercises that help improve the visual system.

Orthokeratology (Ortho-K)

Orthokeratology, also referred to as corneal reshaping treatment, is “a non-surgical vision correction alternative,” says Rodney. Corneal reshaping (CR) is a therapeutic process which reshapes the cornea using reverse geometry contact lenses. This flattens the cornea to reduce nearsightedness.

There is “no age barrier to this procedure as it is safe for both children and adults,” says Rodney. The non-surgical vision correction procedure can correct refractive errors such as mild to moderate and even large (in some cases) myopia, hyperopia and astigmatism. Ortho-K is safe and effective for children as it has been proven to treat myopia effectively. Evidence based practice has made the process very safe provided a minimum standard of care is followed. Thus includes regular checks with your orthokeratologist, tap water never used on the lenses or case at any time, hydrogen peroxide disinfection, 12 monthly lens replacement, and a perfectly fitted lens from an experienced orthokeratologist. The procedure is not effective on certain shaped corneas. “Ortho-K is also suitable for sportsmen and women, swimmers, and simply those who do not wish to wear glasses or contact lenses,” says Rodney.

Like refractive surgeries, Ortho-K gives clear unaided vision, however it has no surgical risks and is reversible. The most important part for children though is the proven effectiveness against minimising myopia progression. So it has a large preventative effect.

The Ortho-K gradually reshapes the front surface of the cornea to reduce myopia, hyperopia and astigmatism. The vision retainer is similar to contact lenses, but are worn at night while sleeping.

While asleep, “the lens uses the force of the eyelid and tear fluid beneath the lens to reshape the top of the cornea,” says Rodney. Upon awakening the patient’s vision remains clear throughout the day, without using contact lenses or glasses.

“This procedure is non-surgical vision correction is painless and reversible,” says Rodney. Ortho-K does not permanently change the shape of the eye. “The eye shape will revert to its original state within one to two weeks if the lenses are no longer worn,” says Rodney. However, improvements are visible the day after, and the procedure stabilises after a week. The process for high myopia, astigmatism and hyperopia, can take up to two to four weeks to achieve full correction.

The Ortho-K lens “offers relief from problems associated with contact lenses, such as dry eyes, and dust that may get trapped in and under the contact lens,” says Rodney.
