Several types of corrective eye surgery exist today and these different types of corrective surgery fall under two main categories:
Excimer Laser procedures (Laser Vision Correction)
Non-Excimer laser procedures
As is the case with other conditions that affect the body, major technological advances have been made in recent years in the field of corrective eye surgery. The following is a brief introduction to the two categories.
Understanding Laser Vision Correction Eye Surgery, LASIK, PRK, Excimer Laser Procedures
Excimer Laser Procedures – ‘Laser Vision Correction’
An Excimer laser is a tool that was approved for the treatment of near sightedness, ranging in severity from mild to moderate. Use of the Excimer laser for vision correction is complicated, and it’s important to work with ophthalmologists who are both trained in the surgical procedure and who have demonstrated the ability to properly operate and calibrate this precision instrument.
The Excimer Laser was originally approved for PRK, or Photorefractive Keratectomy and its usage was later expanded for LASIK procedures, or Laser in situ Keratomileusis.
With ‘PRK’ Laser Vision Correction, the cornea is reshaped by eliminating excess tissue from the cornea’s outer surface. With each computer calculated lightening-fast laser pulse, a microscopic ultraviolet light beam removes the excess tissue. After only a few minutes and the application of local anesthesia, the procedure is over. In just a day or so, patients can resume normal activity.
With ‘LASIK’ Laser Vision Correction, the eye doctor rather than the laser’s built-in computer determines where incisions will be made and how much tissue will be removed. This is a more complex and invasive procedure and it is one that is recommended for more severe refractive conditions. Using a microkeratome (a knife), the eye surgeon slices and then pulls back a flap of the tissue covering the cornea. With the tissue out of the way, the laser is then used to remove tissue and reshape the cornea. The flap is put back into place and the patient typically can see well enough to drive home after the procedure. LASEK and epi-LASIK are variations of the LASIK Laser Vision Correction procedure.
On the other hand:
dental condition affect also your body condition. Even if we are talking specially about your eyes, here is a little brake and we give you some places to find over-seas some cheap but good dental specialists. For Eastern Europe we recommend Romanian guys like this one: medic stomatolog brasov . If you are in UK: dentist UK cost is a useful directory to start searching.

These are procedures that rely on artificial implants, surgery and reshaping to correct eye problems. Lens implants are effective for individuals who have cataracts, nearsightedness and farsightedness. Intraocular lenses or IOLs are used as replacements for the damaged cloudy lenses caused by cataracts. New and improved artificial lenses now incorporate the use of hinges that allow the eye to move and act like a real lens.
Other types of implantable contact lens can correct nearsightedness and farsightedness. They act much like removable contact lenses but require no maintenance and wearers cannot feel these lenses and implants.
Thermokeratoplasty involves the use of heat to manipulate the collagen within the cornea. In doing so, refractive errors can be corrected in a matter of minutes. There are two types of Thermokeratoplasty procedures. Laser thermal keratoplasty or LTK involves the use of holmium YAG laser and CK or conductive keratoplasty involves use of radiofrequency waves.
Astigmatic Keratotomy (AK) involves cutting the cornea in order to reshape it. However, its use has diminished since laser treatments involve less risk and are far more effective at reshaping the cornea.ng!
