What are the different types of foresight surgery?

There are several surgical treatment procedures for repair of hyperopia, which is better known as the area. Most of the possibilities of surgery for foresight use special lasers and heat sources to transform the cornea. Various laser surgical possibilities are hyperopic laser in-Situ keratomileusis (H-alia), excimer laser photorefraction keratectomy (H-PRK), laser epithelial keratomileusis (H-LAZEK) and laser thermokeroplasts (LTK). Implant surgery and conductive keratoplasty intraocular lenses (IOL) usually do not include laser during the procedure.

The prudent degree, along with other factors, will determine the type of surgery to be performed. In most cases, mild to medium foresight can be treated with H-alia, H-PRK, H-Land and thermal Keratoplasty procedures. People who have a serious foresight are usually treated with IOL implantation. With any type of surgery, certain risks and complications should be carefully considered. Complications Crozhsah from altitudeCorrection after the scarring of the cornea, which could eventually lead to blindness.

One of the more common surgical procedures for foresight is H-alia. As with other laser-correction procedures, the H-alien changes the shape of the central cornea by being steeper. Using a knife or laser, a thin flap is cut out of the cornea, allowing contact between laser and central cornea. Many people experience little or any pain after completing the procedure.

both H-PRK and H-LANEK Farsiittedness surgical surgery use surface ablation to change the shape of the central cornea. In the H-PRK, the surface cells of the cornea are removed to transform the cornea while the H-lake is released and eventually replaces the surface surface of the cornea. Unlike H-alike, H-PRK procedures, so h-lake do not include cutting into the cornea to create flaps. Generally ends the time and intensity of pain involving H-PRK and H-LANEK FARSIATEDNESS procedures are longer and more painful than in the procedure of H-alia.

Thermal keratoplasty can be performed by non -contact technique or contact technology. Non -contact technique, LTK, uses laser to apply light pulses to the cornea. Contact technology called conductive keratoplasty uses probes to deliver radio frequency energy to the cornea. In both techniques, collagen fibers in the corneal contract cause the corneal to be transformed. A common complication of both thermal keratoplastic procedures is the risk of formation of astigmatism.

There are different procedures of Iol surgery, which are effective for severe foresight, such as the extraction of pure lens (CLE) and facial intraocular lens (piol). In the CLE, the natural lens is replaced by IOL or clean refractive lens. The ability of the eye to concentrate far on close is very reduked after the CLE with the IOL implantation procedure. The piol procedure deals with Iol implant in addition to the natural lens of the eye.
