What Is Lasik Eye Surgery and How It Can Help You

The medical sector has seen many innovative developments over the past decade, and none are as groundbreaking as Lasik laser surgery, which is a new and exciting treatment for both near and far sightedness. The term “LASIK” stands for Laser-Assisted in Situ Keratomileusis, which is refractive eye surgery that uses a special laser tool, and this treatment is FDA approved, making it both safe and also very effective in correcting common sight issues.

Laser Vision Correction

Such is the pace of development, the eye surgeon no longer has to rely on manual adjustment, as modern laser treatment involves computer controlled settings, which are incredibly accurate and therefore much safer than using manual adjustment. If, for example, you are planning to have San Antonio LASIKtreatment, there is an excellent eye surgeon who is very experienced with this cutting edge technology. Not every person can have LASIK eye treatment, and the surgeon would thoroughly examine the patient to determine whether or not LASIK treatment is suitable. If a person has cataracts – or any condition that might hinder the healing process – the eye specialist would either recommend another form of treatment, or postpone the treatment until such a time when the condition has improved.

Outpatient Procedures

Laser eye treatment does not require the patient to undergo a general anaesthetic, and a few drops of special eye anaesthetic makes the prodecure completely painless. There is very little discomfort after the surgery, which lasts no more than an hour in total, and the patient is advised not to drive home, as it is normal to have blurred vision for a short time after the treatment, so make sure you are accompanied by a driver on the day of the treatment, who can take you home.

How Does LASIK Surgery Work?

The process begins with the eye specialist using a special laser to create a thin flap over the cornea, which is then pulled back while still hinged to the cornea, and then the surgeon uses an excima laser – which removes tissue from the eye surface – using special, short wave, ultra-violet light. The excess corneal tissue is carefully removed by vaporising the selected tissue, and the specially formulated laser can be very finely adjusted.

Pre-Op Preparation

Typically, the eye specialist will map a patient’s eyes prior to carrying out the treatment, and this data is used to configure the laser, thus reducing the risk of human error, and one of the reasons LASIK surgery works so well, is it holds very complications, something that cannot be said about its predecessor, namely, photorefractive keratectomy, or PRK, as it is known. This was the first generation of laser eye surgery, and the LASIK prodecure is far less complicated and this greatly improves the chances of success.

For nearsightedness, the cornea must be flattened, while it is given a steeper surve for farsightedness, and rather than completely removing the outer cornea layer (as with PRK), the LASIK surgery retains this layer, which is replaced after the targeted tissue is removed. If the layer is removed, it will grow back naturally within a few days, but by peeling it back and replacing it after the tissue removal, recovery is much quicker.

Laser technology allows they eye specialist to correct vision issues by altering the shape of the cornea, and for many people, wearing corrective eye glasses is firmly a thing of the past.
