In current years laser eye surgery has been a common procedure for the correction of vision. It usually involves reshaping the cornea, this is the clear layer that covers the anterior part of the eye. This surgery is normally done using a special laser referred to as excimer. There are different procedures used in the correction of hypermetropia (long sited), myopia (short sighted) and antagmatism.
The following are some of the common types of procedures used in laser eye surgery:
Photorefractive keratectomy (PRK)
- The procedure has been used from late 1980s. However, after the growth of LASEK and LASIK, it is now used only for low prescriptions correction.
The Laser in situ keratomileusis (LASIK)
- This procedure has been executed ever since mid-1990s. It can be used in the correction of both short and long sightedness. However, it may not be appropriate for high prescription correction.
- It is an ideal form of LASIK that decreases the natural abnormalities of the eye and eyesight correction.
The Laser epithelial keratomileusis (LASEK)
- This method is similar to PRK, however, in this case, the epithelial layer of the cornea is reserved as a flap. The epithelium retention is alleged to speed up the healing process and prevention of complications.
The expectation after the laser eye surgery
After the surgery, you will be capable of seeing, but blurry for a few days and you may also feel some grittiness in the eye. Please don’t rub it, instead use eye drops to reduce the itching. If you wore eyeglasses before the surgery, you will not require them because at this point you will rely on your natural eyesight.
In the following day, you will be required to go for a check-up with your eye surgeon for testing of your vision. At this time, most of the patients have 20/40 vision. After a few days, you will be able to see clearly, however, your vision will continue to recover for some weeks. According to Optilase scheduled check-ups with your eye Doctor should be followed to monitor the progress in your eye/eyes.
The duration of the effects of laser surgery
A complete recovery of your vision is achieved in most cases after three to six months. However, some patients may still require glasses. If your vision is still blurry, a visual enhancement will be suggested to obtain visual sharpness
Approximately 10% of patients may need this small procedure. However, if your eyesight still has a vision 20/30 or poorer, your optician will recommend for you a pair of low power eyeglasses. For those patients who are between the age of 40-45 and over that prefer laser surgery for correction of their long sightedness, short sightedness or astigmatism, their vision will improve and remain so for many years.
The risks of laser eye surgery
Complications normally occur in less than 5% of patients who undergo laser eye surgery. Some of these complications includes; the problem of drying eyes that normally occurs some months after the laser surgery. Some patients have a glare problem or halo effects some few months or weeks after the surgery. This is most common after the short or long sightedness correction procedure.
Those patients who wear glasses are in a position to note the continuous changing of their eyes and therefore, it is advisable to always change your lenses every time. It is unfortunate that laser eye surgery does not stop the weakening and natural changes in your eyes as you grow old.
Some of the major changes in our vision usually occur in our forties. Especially the vision of very close objects becomes blurred, this condition is referred to as ‘Presbyopia‘. It is the loss of the ability to concentrate on objects that are close to you. This problem is very common.
Natural weakening of your vision will still continue whether you have the laser surgery or not. Generally, most patients who undertake laser surgery get immediate improvements in eyesight and do not require to glasses again. Some patients who had undergone laser surgery ten years ago have shown excellent results of having long lasting vision and others have maintained the normal vision of 20/25. Therefore, this advantage can last for so many years, making it a worthy treatment.
