Refractive Eye Surgery

Refractive eye surgery is very effective for correcting refractive errors and visual decreasing dependence on glasses and contacts. It has proven itself in the reduction of myopia (nearsightness), astigmatism (elongated corneas), hyperopia (farsightedness) and many other problems caused by refractive errors.

The drug is composed of four types of refractive eye surgery procedures: procedures cornea, flap and photoablation procedures, implants and thermal procedures. Today's technology allows doctors to use lasers to reshape the cornea.

In a flap procedure, the surgeon cuts a tiny flap in the cornea to reshape the tissue underneath and correct the refractive error.

Lasik (Laser Assisted In-Situ Keratomileusis) is very popular in the field of refractive surgery can correct astigmatism, hyperopia and myopia. Initially, the surgeon uses an IntraLase laser or a microkeratome to move a piece of the stroma.

It then uses an excimer laser to remove excess corneal tissue and only after he replaces the flap.

The best candidates for Lasik are people with thin or flat corneas. A blade cuts small bit in the epithelium while a mild alcohol solution to smooth the edges. Excess corneal tissue is removed with an excimer laser and the end of the flap is replaced.

Like LASEK, Epi-LASIK cuts the epithelium, but epikeratome is used as a replacement for alcohol and the blade.

The second stage of flap procedures is because it removes excess photoablation of corneal tissue with ultraviolet radiation. The laser surgery eye surgery was original PRK (photorefractive keratectomy).

This intervention used local aesthetic eye drops to numb the eye followed by reshaping the cornea. The excimer laser is an ultraviolet beam of light controlled by the computer that causes no damage to the tissues around the eyes.

arcuate keratotomy and radial keratotomy are two procedures that alter the cornea surface of the cornea to correct refractive errors. radial keratotomy (RK) incisions made some spoken form of the cornea with a diamond knife and in doing so he can treat nearsightedness.

Arcuate keratotomy is almost the same, except that the knife cut diamond parallel incisions near the cornea.

Farsightedness or temporarily hypermetropic refractive errors can be corrected with the heat Please thermal processes. During the thermal keratoplasty procedure, the surgeon makes a ring of 8 or 16 small burns around the pupil.

The heat causes contractions and makes the cornea steeper.

includes thermal keratoplasty laser thermal keratoplasty (LTK) with holmium laser and conductive keratoplasty (CK) with high frequency electric probes.

Last but not least, we have the implants. Thank you to implantable contact lens (ICL), inserted into the cornea through small incisions, many patients suffering from astigmatism, hyperopia and myopia have been cured. ICL sits behind the cornea and refocus light provides a natural image.
