What Is LASIK Laser Eye Surgery?
By Dean Brooks
LASIK laser surgery is an intricate surgery procedure used to treat all degrees of nearsightedness. The doctor who performs it uses a small scalpel to cut a flap of the cornea, then removes part of the underneath tissue with a laser and put the flap back in its place.
In LASIK surgery, the skills of the physician or surgeon are more important than in the PRK procedure, where the computer does most of the work. This is the reason why it is mandatory to find a high-skilled and experienced surgeon who has done several such procedures before to perform it. The success of this procedure depends mainly on the doctor.
Advantages Of LASIK Surgery
Most physicians agree that this kind of surgery is very appropriate for correcting very severe vision problems. It also allows a faster recovery than PRK and other procedures. In addition, patients who have undergone a LASIK laser surgery can see accurate enough to drive and read within just a week or so.
Does LASIK Laser Surgery Have Risks?
For a limited number of patients, LASIK laser surgery can have some negative side effects, which include over or under-correction, scarring of the cornea, astigmatism, corneal infections, lower contrast sensitivity or problems with driving at night.
LASIK Laser Surgery versus PRK & RK
There are physicians that still consider other surgical procedures as well. Some patients who had previously decided on LASIK laser surgery are often advised to undergo a so called PRK or RK procedure
instead. After studying all the options they have and consider the possible side effects, many of them eventually agree on other methods.
Many clinical centers, while they do perform LASIK laser surgery in many situations, they claim that other procedures or methods are in some cases more suitable. For instance, some physicians believe that for a small number of patients with low or moderately nearsighted conditions, a RK (radial keratotomy) is more appropriate.
RK is an earlier correction surgery procedure that does not need an Excimer laser. The incisions are made radically along the exterior portion of the cornea with a hand-held scalpel. Such procedures are intended to help reshape the curvature of the cornea and allow light rays that enter the to focus properly on the retina. The success of the method depends on the length and number of these incisions. Some surgeons use this type of surgery for a small number of people with a disorder called mild myopia.
In contrast, other physicians and surgeons consider LASIK laser surgery as the best option whatsoever. While they do mention other options to their patients, such as PRK or RK, they don't recommend them in favor of these procedures.
Others claim that a RK procedure involves penetrating around 90 percent of the cornea, which can have negative impacts on the structure of the eye. Moreover, once you have undergone a RK surgery, you can never repeat it or have a PRK. This is the reason why some doctors would never recommend this method to anyone.
