Vision CorrectionVision correction surgery provides a phenomenal sense of freedom for those who have depended on glasses or contact lenses.
Outcomes have improved significantly with increased availability of options. Laser vision correction is now the most commonly performed elective procedure in the world and accepted to be as safe (if not safer) than continued use of contact lenses.
For those whose vision has deteriorated with age, a wide range of special lens implants are now available to address the need for reading glasses as well as tackle short or farsightedness if necessary.
But as with any surgery, your surgeon's expertise and experience is as important as the procedure and technology used. Seek out a clinic where your eligibility for surgery is assessed by an eye surgeon (not an optician) and one who is a specialist in the cornea (the front clear window of the eye).
Laser vision correction
IntraLASIK is the GOLD STANDARD for laser vision correction and is the safest and most precise laser vision correction procedure available today.
The use of a second laser (Intralase) to create the micro-thin flap needed on the front of the eye has over 100 times the accuracy of a traditionally used blade microkeratome or LASIK.
The main benefits are BETTER vision, improved predictability, less dry eye and elimination of blade related complications. In addition because IntraLASIK accurately cuts thin flaps, many deemed unsuitable for LASIK because their corneas are too thin for their level of prescription, are able to benefit from the procedure.
Higher levels of correction are performed with IntraLASIK compared to LASIK. Treatable prescriptions range from +5 dioptres (longsighted) to -15 diopters (shortsighted), and up to +5 dioptres of astigmatism
Age related options
If you have passed your fourth decade and only recently found yourself reaching for reading glasses, it is likely to be the lens inside your eye causing your visual problems. This is called presbyopia and unfortunately comes to everyone eventually. Some clinics recommend laser surgery using 'mono' or 'blended' vision. Here the surgeon under-corrects one eye to aid near vision and corrects the other for distance. While it can be very effective, not everybody likes it. If you are considering this option it is well worth taking the time to mimic the same effect using contact lenses for a few weeks first ' some clinics will insist on this.
Considering lens implants may be a better alternative if you are in your mid fifties or more. This procedure has many names include Refractive lens exchange, Prelex, Multilex, Multi-focal Implants and Added-Value lenses. The surgical process is the same as an early cataract replacement and has the added benefit of eliminating the need for cataract surgery later in life. As with cataract surgery your natural lens is removed, but rather than replacing it with a single focus lens, a special lens is inserted that allows you to focus on near and distant objects. There are a number of lenses available, all of which are extremely effective. A good centre will have a variety of lenses available and the choice should be made by your surgeon based on you as an individual and your lifestyle requirements.
Implantable Contact Lenses
Implantable Contact Lenses (ICL) are a superb option for those not suitable for Laser vision correction. As the name suggests, a small lens not dissimilar to a contact lens is surgically implanted into your eye. They provide superb and highly predictable visual outcomes, and have the added advantage of being removable and reversible!
'Centre for Sight' is a world renown facility based at the famous McIndoe Hospital in East Grinstead, and headed by one of the most innovative Ophthalmic surgeons in the UK Mr Sheraz Daya, who has won many accolades for his ground breaking work in this field of vision correction.
