What people think of when they hear vision correction – Lasek
Most people when thinking about vision correction still think of LASEK. As it was the first widely adopted and reliable procedure, it’s the go to very any type of vision correction conversation. In fact, many people even use the words vision correction and LASEK synonymously so as to mean the same thing. Vision correction has come a long way in recent years and now vision correction has become fantastically evolved, with various options available to suit each patient’s needs and concerns.
How vision correction has evolved
Vision correction started in the 1980’s with a procedure called ASLA, advanced surface laser ablation. This then developed into PRK or LASEK, which was introduced in 1995 in the USA and is still used today. Unfortunately, PRK takes a while to fully recover and the discomfort is slightly more pronounced compared to other procedures. After LASEK, Blade LASIK was developed which sped up recovery and reduced discomfort. Then by the use of the femtosecond laser, LASIK become a bladeless procedure which ushered in the modern era of vision correction. Since then, two new techniques have been developed for vision correction. One of them is called SMILE, created by the Medical Technology segment of Zeiss, which corrects vision by just making a small incision as opposed to removing the flap, as is the case with LASEK and LASIK. Lastly PIOL, lens implantation, is a procedure where a lens is implanted into the eye in order to correct vision.
These are the basic forms of modern laser vision correction: LASIK, LASEK, and SMILE
First, we have the three basic laser vision correction options, namely: LASEK, LASIK and SMILE. These are just your basic modern options.
LASEK – All laser LASEK is a procedure during which the corneal epithelium is removed with an excimer laser, and vision is corrected before the cornea is covered with a protective lens.
LASIK – All-laser LASIK is a surgical method that involves opening the cornea with a femtosecond laser and correcting vision with an excimer laser before closing up the cornea.
SMILE – With a highly differentiated femtosecond laser, it is possible to penetrate the corneal surface of the eye which will allow direct laser irradiation to the corneal stroma. Therefore, surgery can be performed in just a few minutes, with a minimal incision thus preserving the front corneal tissue structure, without creating a large corneal flap.
Customized options
In recent years vision correction has progressed so much that it has become much like going to a tailor to have a suit fitted. These new vision correction methods are called customized options. Customized options are ways which you can customize your vision correction procedure.
XTRA VISION(Corneal Crosslinking) – Is a procedure that helps make the cornea stronger by increasing the binding force of collagen in the cornea. This is done by applying a type of serum to the exposed corneal bed and then diffused to it. Once the serum has penetrated the stroma, it is prepared to cross link with the cornea. Then using UV light, the cross linking is further facilitated. XTRA VISION is available for SMILE, LASIK and LASEK.
Contoura vision – Is a technique that checks for refractive errors in your eyes, including: corneal shape, myopia, and astigmatism. It does this through examination of your eye’s corneal topography. These results are then linked to the excimer laser which then makes corrections in accordance with the corneal status of each patient. Contoura vision can be used in conjunction with LASIK and LASEK.
Wave vision(Wavefront) – This type of technology creates a 3D image of the eye. This helps the laser be extremely accurate during treatment of each individual patient. Wave vision can also be used in conjunction with LASIK and LASEK.
LASEK Streamlight – This method also sometimes referred to as the “No Touch PRK” method, removes the surface of the corneas using a very precise and accurate laser. Streamlight is only available for PRK.
