LASIK for those who are suitable, is still the preferred and most reliable form of corneal refractive treatment and together with femtosecond laser it is still the treatment of choice.
They say 50 is the new 40 and 40 is the new 30 but regardless of where we draw the line in the sand, aging is inevitable and so is the need for reading glasses.
Presbyopia – the loss of the ability to focus at near, for most people, begin in their early 40′s, resulting in the need for visual hardware or correction for any near tasks, like reading, computer work, knitting, sewing even reading a menu or shopping list. In this day and age of convenience needing reading glasses or contact lenses for such tasks is the epitome of inconvenience.
Reducing the need for reading glasses is a possibilty via Clear Lens Exchange or via Laser Vision Correction.
The aim of vision correction or refractive surgery is to reduce dependency on glasses and contact lenses to achieve clarity of vision.
There is now very little that cannot be treated or corrected. While there have been leaps and bounds to refractive surgery with Laser Vision correction and Refractive Lens Exchange now becoming the “norm”, it is always important to understand that these procedures can have their limitations – realistic expectations is a must to avoid dissappointment. Furthermore by choosing an experienced surgeon you trust, increases the likelihood of success, whether it be Laser Vision Correction or Refractive Lens Exchange.
Since the dawn of Surgical treatment of cataracts in the mid 1700′s, surgical techniques have improved in leaps and bounds – sutureless wounds, incision getting smaller and a wide array of Intraocular lenses becoming available to make it possible to treat short-sightedness, long-sightedness, astigmatism and even presbyopia. Resulting in better vision post operatively with little or no need for visual hardware and shorter recovery time.
Now there is “Laser Cataract Surgery” – is it worth the extra cost?
Currently, research shows post operative results with “laser” cataract surgery is no better in comparison to conventional cataract surgery performed by an experienced surgeon.
With improvement of technology and a wider knowledge of who is suitable, the risks of Laser Eye Surgery is at its lowest.
We face risks day in day out, wether its crossing the road or driving a car it is an inevitable part of life – it is all around us, however there are ways in which we can reduce them.
The best way to reduce risks associated with Laser Vision Correction is to choose an experienced surgeon, who has proven track reckord and who utilises the latest technology.
Ensuring suitability and completing a full comprehensive eye health check prior to the procedure is also imperative to a successful result.
People are living longer, more active lifestyles and often find visual hardware such as glasses and contact lenses inconvenient.
Freedom from visual hardware to see clearer is now a posibilty for more and more people. These days, there are a myriad of corrective procedures that can be performed in order to have clear unaided vision, so being unsuitable for one procedure, doesn’t automatically mean the end of the road.
Shortsightedness (also called Myopia) Longsightedness (Hypermetropia/Hyperopia), Astigmatism and Presbyopia, can often be confusing for patients enquiring about Vision Correction. The question “Which one are you?” is often the first that is asked.
Myopia or Shortsigtedness usually means your eyes may be longer than normal or the cornea is steeper than normal – the eye focussing images in front of the retina without correction. Depending on the amount of shortsightedness a person has, people who are shortsighted normally have clearer vision up close and blurry distance vision.
Longsightedness or Hypermetropia/Hyperopia usually means your eyes may be shorter than normal or the cornea is flatter than normal – the eye focussing images behind the retina without correction. Depending on the amount of longsightedness a person has, people who are longsighted normally have clearer vision at distance and out of focus for near.
Astigmatism has to do with the shape of the cornea – simplified, the “normal” cornea is shaped like half a basketball however people with Astigmatism have corneas shaped more like a football – steeper in one direction and flatter in the other.
Presbyopia on the other hand usually affects those 40 and above, gradually losing the ability to read things at near without visual hardware. This is due to the Lens inside the eye losing its elasticity, thus becoming unable to foccus when things are at a close range.
Confusing as they may be, all these conditions can be corrected with either Clear Lens Exchange or Laser Vision Correction, to reduce and sometimes even completely remove the need for visual hardware to attain clear vision.
Blended Vision or Monovision is a term coined to describe when each eye is corrected differently to each other – focusing one at distance and the other either near or intermediate distance, in view to reduce the need for visual hardware at both distance and near. Blended vision can be attained via laser eye surgery or intraocular lens implant.
Understanding presbyopia is the first step in grasping the concept of blended vision. As with any procedure what is most important is choosing an experienced surgeon and ensure thorough understanding of the pros and cons.
A trial prior to a decision is important to “test drive” what blended vision is and whether or the difference between each eye can be tolerated.
Reserved for presbyopic patients who have lost the ability to read unaided, blended vision is yet another option for those looking to reduce dependency on contact lenses or glasses.
The key to attaining the clearest, sharpest vision possible after laser vision correction is having customized laser vision correction. This is made possible through wavescan technology that allows the surgeon to take a “fingerprint’ scan of the eyes and evaluate their unique characteristics.
This technology essentially allows the surgeon to customize or personalize the treatment not just between patients but of each eye.
Whatever your choice of vision correction is, it is of utmost importance that your procedure is customized – tailored not only to your eyes but also suited to your lifestyle.
Whether it is customized laser eye surgery or cataract surgery, full informed consent and counselling of the procedure, its benefits and risks should always be discussed with you before a decision is made.
Full understanding of both the benefits and limitations of any procedure will increase the likelihood of a successful outcome.
