Laser Eye Surgery

Laser Eye Surgery – Procedure and Options Abroad

LASIK (Laser Eye Surgery), a common type of refractive surgery, is offered to correct vision problems and reduce or eliminate the need for eyeglasses and corrective lenses. The idea of the lasik procedure is to reshape the cornea of the defective eye in order to refract light rays properly. In this way they can focus on the retina with more precision and produce a sharper vision.

The procedure is also referred to as laser vision correction and is performed by and ophthalmologist using a microkeratome. Lasik surgery represents constant advances in the treatment of refractive errors for patients who suffer from the following conditions or vision problems:

  • Myopia – also called nearsightedness, when the person sees close objects more clearly than those far away.
  • Hypermetropia – also called farsightedness, when near vision is blurred and also distant vision in some cases.
  • Astigmatism – the disruption of focus both in near and distant vision.
  • Presbyopia – refers to eye changes due to the aging process, which reduced the ability of the eye to change focus.

Laser Eye Surgery Procedure

A pre-surgical exam is made to take detailed medical history, using specialized equipment to measure the cornea, its shape and irregularities.

The doctor also determines the areas of the cornea that need reshaping, allowing the specialist to chart the eye and remove the tissue precisely using highly specialized instruments. With the help of wavefron tech the aberrometer, a map of the eye, is created.

The doctor uses this information to program the laser. Each pulse of beam removes an amount of corneal tissue, allowing the surgeon to flatten, or make steeper the curve of the cornea.

During surgery, usually completed in less than 30 minutes, the patient lies on his back in a chair, takes some relaxing medicine and a few drops are administered to numb the eyes. The doctor places an instrument to hold the eyelids open. Before cutting the corneal flap, some pressure is given.

A special blade cuts the flap to allow access to the cornea. Then the laser is used to adjust specific parts of the cornea, while the patient, as instructed, fixes the vision in a light. Then the flap is folded back. Some burning odor can be felt during the lasik surgery procedure.

It is important to shield the eyes during one month in the evenings, to protect it while healing. It takes a couple of months before the sight is stabilized.

Common Risks of Laser Eye Surgery

Depending on the condition, the ophthalmologist will suggest corrective lenses or eyeglasses before laser eye surgery. It is also important to consider the risks and discuss the benefits of the procedure.

Some of these risks require additional surgery in order to correct the results and they should be performed within a year. Some lasik surgery risks are:

  • Astigmatism – caused by uneven tissue removal.
  • Double vision, glare and halos – could be treated sometimes with eyedrops containing crticosteroid, but usually requires second lasik surgery.
  • Undercorrections and Overcorrections – happen when too little tissue or too much tissue has been removed.
  • Dry eyes – due to the lasik surgery, tear production is reduced. Lubricating eyedrops are recommended.
  • Some other problems may arise during surgery, for example infection, swelling or excess tears, due to flap folding.

Despite the risks, lasik surgery is usually a safe procedure with excellent success rates.

Some health conditions like autoimmune disorder, rheumatoid arthritis, HIV, dry eyes, unstable vision, pregnancy and keratoconus can increase the risks associated with laser vision correction. Individuals considering lasik surgery should talk to their doctor and ask about how the surgery can help.

Laser Eye Surgery Abroad

Lasik eye surgery is considered an elective surgery, so medical insurance companies do not cover the laser eye surgery cost. Laser eye surgery abroad is a good option for those considering having the procedure and care to save up a few thousands of dollars on medical costs.

In the U.S., the laser eye surgery cost vary enormously, from less than $1,000 to more than $5,000, but most patients pay an average $2,000 per eye depending on the condition to be treated.

Countries like Brazil and Colombia offer high quality service for a fragment of the North American.
