Understanding Laser Eye Surgery
Those who have long suffered from refractive errors will be glad to know that there are revolutionary laser techniques that can help rid them of the hassle of wearing corrective eyewear and benefit from a newfound sense of freedom. These types of laser eye surgeries have grown in popularity in last couple of years – with the advancement of technology and extensive surgeon research in this field - which has resulted in a broader range of people who fall into the suitability bracket.
The most common (and successful) forms of laser eye surgery used to treat refractive errors are LASIK and LASEK (PRK) procedures. Although very similar in terms of results – with most patients regaining 20/20 or 20/40 (driving standard) vision – the procedures themselves are slightly different. After undergoing a thorough screening process, your surgeon will determine your suitability for one of the above surgeries. While LASIK is the most common of all laser eye surgeries, candidates that have a cornea that is not thick or too flat to withstand the LASIK method can be deemed suitable for the LASEK procedure.
The laser eye surgery procedures
The LASEK procedure entails preserving the corneal epithelium – in this way it differs from LASIK surgery as the ophthalmic surgeon does not create a corneal flap or scrape and remove the epithelium. Instead, your laser eye surgeon will treat the area with a diluted alcohol solution which loosens the epithelium. They will then roll back the loosened tissue and work with a laser on the exposed corneal tissue beneath. One the surgery has been completed, the surgeon simply rolls back the epithelium cells smoothly into their newly reshaped position. This reshaping process changes and channels the refraction of light which results in vastly improved vision.
During LASIK eye surgery, your surgeon would have examined your cornea to ensure that it is thick enough to withstand the treatment which entails a laser or a computer-controlled instrument creating a very thin, circular flap of tissue in the outer epithelium. Once this has been cut away and moved aside, the surgeon is provided with a working space in which he reshapes the cornea to change the light refraction in the eye.
Who has benefitted?
Countless people have benefitted from a revolutionary laser eye procedure. The British television Presenter, Phillip Schofield, featured his laser eye surgery experience on ITV's This Morning Show – where he clearly illustrated his delight in the instantaneous results and drastically improved vision. The world–famous golfer, Tiger Woods, also underwent laser eye surgery to correct his vision – it's no wonder he knows how to keep his eye on the ball. In fact, after undergoing the procedure, he went on to win his next five tournaments! A few years ago, Adam Clayton, who plays the bass guitar for U2 also underwent laser eye surgery to correct his refractive error. He reported an improved ability to play the bass as well as improvement in his vision when driving at night. Some other famous celebs that have benefitted from laser eye surgery include: Drew Carey, Elton John, Barry Manilow, Brad Pitt, Cindy Crawford, Nicole Kidman, Michael Bolton, Carlos Santana and Kim Kardashian.
When looking at the list of various international celebrities, it is clear that there are various fields of occupations that can benefit from laser eye surgery. No matter who you are, laser eye surgery can make the world of difference to everyday activities. On top of the vast improvement in vision, many people who have undergone this procedure boast of an improved self-confidence and a mighty boost to their self-esteem.
Which refractive errors are correctable?
Laser eye surgery is one of the ideal options when it comes to correcting the following refractive errors:
• Long-sightedness (hyperopia)
• Short-sightedness (myopia)
• Astigmatism (irregular shaped cornea)
The results, benefits and freedom
Not only are numerous people benefitting from improved vision, but many stand testimony to the incredible difference this procedure can make to everyday life. A LASIK or LASEK laser eye surgery procedure means that the patients who were previously hounded by the financial qualms of glasses or contacts are free of the hassles and afforded the freedom to make their form of corrective eyewear, redundant. Simple tasks like catching a ball, reading the paper or admiring a view are made simpler and more enjoyable. Another fantastic feature of this particular form of laser eye surgery is the fact that patients hardly experience pain, in fact – the procedure involves little to no discomfort.
Post laser eye surgery treatment
To ensure a speedy recovery and relieve any possible temporary discomfort, patients are given prescribed medicated eye drops. To avoid the accidental rubbing of eyes while sleeping, patients are provided with a night shield for roughly the first week. In some cases, patients are fitted with soft contact lenses which also provide further protection and aid the healing process.

Modern eye care has seen great strides made in countering serious eye conditions. Not least amongst modern procedures like laser surgery, which has proven itself capable of treating many of the common conditions affecting us all.

In order to correct vision, surgeons use lasers to reshape the cornea by intervening on the tissues on the underlying or stromal layer. The medicine currently comprises two very effective types of laser eye surgery: the Photo Refractive Keratectomy (PRK) and the Laser-Assisted In Situ Keratomileusis (LASIK).
New surgical techniques now make it possible to significantly reduce or permanently eliminate the need to wear corrective eyewear. This holds true even for people with a very high degree of refractive errors and have to use thick lenses. This article discusses refractive surgery and its role in correcting common refractive errors such as short-sightedness, long-sightedness, and astigmatism.
LASIK surgery is the most common of all laser eye surgeries performed and the procedure has, to date, allowed many individuals across the world regain their waning eyesight. Find out more about this vision correction procedure.
