Laser eye surgery

Laser-Assisted in Site Keratomileusis usually referred to as LASIK is carried out to correct eye problems caused by myopia, hyperopia and astigmatism. The procedure is carried out by a specialist in medical and surgical eye problems commonly called an ophthalmologist. This eye treatment uses a laser to redesign or restructure the cornea. The procedure is meant to improve visual accuracy and make images clearer and sharper.

Lasik procedure

Lasik eye treatment is no different from other surgical procedures such as photorefractive keratectomy, and the person who undergoes the procedure usually feels after affects at the conclusion of surgery. After surgery the person might experience some problems such driving at night, seeing circles around lights, dry eyes and patterns or lines originating from a center point in the shape of stars (starburst). Patients who do need eye surgery can use spectacles or contact lenses.

Advantages of laser surgery

Every year around 100,000 people in the UK undergo this procedure because it causes no pain, takes only ten minutes to be carried out and completely heals in a few hours. People opt for this procedure because it frees them from the hassle of spectacles or contact lenses. People do worry about this procedure, but if performed by a competent surgeon, it is absolutely safe. It is better if you check out a few surgeons before deciding upon the person who will perform your procedure.

Different types of Lasik

Basically every procedure is performed with a particular type of laser which is commonly known as an ‘excimer laser’. All Lasik procedures are the same, but the lasers used are supplied by different manufacturers. However, there are different types of laser ablations patterns that are carried out. These include wave-front optimized treatment and wave-front guided treatments. Femtosecond is a completely dissimilar type which can also be used instead of the traditional mechanical microkeratome for eye treatment.

Conventional Lasik

Conventional Lasik is the ablation or prototype that is part of most lasers. This form of eye treatment operates directly on the patient’s eyeglasses, and has specific notable characteristics for each patient. This surgical procedure works on most patients but it usually has more side effects than other common procedures. The side effects are problems with brightness, seeing circles around light and reduced vision at night. Other surgical procedures do not have these problems as often as Lasik.

Vision when we age

When a person is young, the normal lens possesses the capability of transforming its form and capacity. This accommodates concentration on objects that are near through a means of lens dominance. With the advent of old age, this normal lens loses its flexibility and cannot change its shape. This is presbyopia which is the impairment of vision which leads to using reading glasses or other visual equipment to be able to read or do work that requires near sightedness.

Although Lasik cannot repair this accommodation, but there are some adaption’s which are successful such as blended or mono-vision. This procedure corrects one eye for farsightedness and one eye is corrected for nearsightedness.
