Patients seeking permanent revision of tasteless vision problems such as nearsightedness now have a selection between surgically implanted lenses, called phakic Iols (intraocular lenses), or the primary Lasik surgery. Both procedures work by changing the way light rays enter the eye and both procedures can help sharpen vision and greatly diminish dependency on glasses or feel lenses. The type of laser eye surgical operation or lens implant recommended will be based on the age of the patient, corneal thickness and the condition and lifestyle of the individual.
[b]Lens[/b]Lasik Eye Surgery
Lasik uses power to reshape the cornea and is productive in treating nearsightedness (myopia), but is not recommended for patients with severe vision impairment. The reshaping of the cornea in Lasik is permanent as it involves extraction of tissue from the cornea of the eye, thus changing its shape. The eye surgeon uses a computer to intuit the exact whole of cornea that needs to be removed from each patient's eye, and then he creates a thin cellophane flap on the face of the cornea. The surgeon then lifts the flap, positions the laser and delivers a pre-determined whole of ultraviolet light pulses onto the newly exposed part of the cornea. Every pulse of the laser removes a little layer of cornea.
When the Lasik surgical operation is unblemished the flap is put back in place without stitches so that it can adhere simply to the treated cornea. This policy flattens the town of the cornea, enabling light rays to be more focused and precise on the retina, thus making images more sharp and clear. Any separate forms of Lasik are used today, each depending on how the flap on the cornea is created.
Lens Implants
Patients that do not qualify for Lasik because of very high myopia or very thin corneas are potential candidates for surgically implanted lenses, also called phakic Iols (intraocular lenses). This new selection offers a more permanent revision of tasteless vision errors such as myopia (nearsightedness). These implants, which bear a similarity to feel lenses, are placed between the cornea and the iris. Some eye surgeons think Iols the best selection for extreme nearsightedness. Unlike primary lens implants, which typically provide clarity in whether near, intermediate, or length ranges, multifocal and accommodating lens implants offer the expectation of good vision at more than one range.
Unlike Lasik, surgically implanted lenses do not need tissue extraction from the eye. The patients natural lens remains in place to focus from far to near in a natural way, it is intended for younger patients who are still able to focus well, but may also be used on older patients as long as they retain enough focusing ability. Convenience and reversibility are just a few of the advantages of this procedure.
