There are many different corrective eye surgeries and research should be done before making this important decision. Those who have been wearing corrective lenses for many years may find their choices are many and information is needed to fid the surgery that is best for them.
Conductive Keratoplasty (CK) is a form of surgery that uses very mild heat from radio waves to round out the cornea. It changes the overall shape of the cornea by shrinking collagen in the periphery of the cornea. This procedure is a simple procedure that only takes about five minutes per eye.
Implantable Contact Lens
Another popular form of corrective eye surgery is the Implantable Contact Lens. This procedure can correct both nearsightedness and farsightedness and usually takes between six to twenty minutes for each eye. This procedure will treat severe forms of nearsightedness and farsightedness.
This reversible procedure places the contact lens behind the iris and in front of your eyes natural lens. These implantable lenses do not need any maintenance and you cannot feel the lenses in your eyes.
Intraocular Lenses are normally implanted during regular cataract surgery. The eyes natural lens is replaced by the implants. Cataracts caused the eyes natural lens to be cloudy and weaken vision. This technique has been used for several decades. Formerly this surgery would be used to provide distance vision and glasses were also needed for any close reading or handwork.
New IOLs have since been introduced that allows your vision to be corrected so it is possible to see near, medium, and far distances without the aid of extra glasses. The new surgery allows the lens to move around in the eye and is limited to those who need cataracts removed.
Researchers hope to gain FDA approval to use this new surgery to correct myopia, hyperopia, and presbyopia. Some surgeons will use this corrective surgery to provide other vision corrections in some circumstances.
Intacs are inserts made of plastic and were once used to treat mild nearsightedness and astigmatisms. These inserts are now mainly used to correct bulging corneas. The inserts are placed in different parts of the cornea to flatten it. This treatment is meant to be permanent but can be removed if necessary. This procedure takes about fifteen minutes and has been approved by the FDA in 2004.
Laser Thermal Keratoplasty is another corrective surgery that uses a mild heat to shrink the collagen at the edge of the cornea. This surgery will correct farsightedness and presbyopia and takes about three seconds.
Scleral Expansion Bands
Scleral Expansion Bands are new and are used to treat presbyopia. The FDA has not approved this corrective surgery and the surgery takes about 30 minutes. The surgeon places four pieces just below the white surface of the eye.
Research is still going on to refine and improve corrective eye surgeries. If you feel you cannot be helped by corrective surgery now, you may be a good candidate for surgery in the future as technology advances. Scientists and researchers continue to look for new and better ways to correct faulty eyesight.
