Patients seeking permanent revision of base foresight problems such as nearsightedness now have a option in the middle of surgically implanted lenses, called phakic Iols (intraocular lenses), or the former Lasik surgery. Both procedures work by changing the way light rays enter the eye and both procedures can help sharpen foresight and greatly diminish dependency on glasses or contact 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 health and lifestyle of the individual.
[b]Lens[/b]Lasik Eye Surgery
Lasik uses power to reshape the cornea and is efficient in treating nearsightedness (myopia), but is not recommended for patients with severe foresight impairment. The reshaping of the cornea in Lasik is permanent as it involves dismissal of tissue from the cornea of the eye, thus changing its shape. The eye surgeon uses a computer to suspect the exact number 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 number of ultraviolet light pulses onto the newly exposed part of the cornea. Every pulse of the laser removes a exiguous layer of cornea.
When the Lasik surgical operation is unblemished the flap is put back in place without stitches so that it can adhere plainly to the treated cornea. This course flattens the center of the cornea, enabling light rays to be more focused and precise on the retina, thus manufacture images more sharp and clear. Some dissimilar 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 possible candidates for surgically implanted lenses, also called phakic Iols (intraocular lenses). This new option offers a more permanent revision of base foresight errors such as myopia (nearsightedness). These implants, which bear a similarity to contact lenses, are settled in the middle of the cornea and the iris. Some eye surgeons think Iols the best option for ultimate nearsightedness. Unlike former lens implants, which typically furnish clarity in whether near, intermediate, or distance ranges, multifocal and accommodating lens implants offer the prospect of good foresight at more than one range.
Unlike Lasik, surgically implanted lenses do not want tissue dismissal 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 support adequate focusing ability. Convenience and reversibility are just a few of the advantages of this procedure.
