Patients seeking permanent improvement of tasteless vision problems such as nearsightedness now have a option in the middle of surgically implanted lenses, called phakic Iols (intraocular lenses), or the original Lasik surgery. Both procedures work by changing the way light rays enter the eye and both procedures can help grind vision and greatly diminish dependency on glasses or palpate lenses. The type of laser eye surgery 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 vigor 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 dismissal of tissue from the cornea of the eye, thus changing its shape. The eye surgeon uses a computer to hypothesize the exact estimate of cornea that needs to be removed from each patient's eye, and then he creates a thin cellophane flap on the outside of the cornea. The surgeon then lifts the flap, positions the laser and delivers a pre-determined estimate of ultraviolet light pulses onto the newly exposed part of the cornea. Every pulse of the laser removes a wee layer of cornea.
When the Lasik surgery is perfect the flap is put back in place without stitches so that it can adhere naturally to the treated cornea. This course flattens the town of the cornea, enabling light rays to be more focused and literal, on the retina, thus manufacture images more sharp and clear. Some different 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 inherent candidates for surgically implanted lenses, also called phakic Iols (intraocular lenses). This new option offers a more permanent improvement of tasteless vision errors such as myopia (nearsightedness). These implants, which bear a similarity to palpate lenses, are located in the middle of the cornea and the iris. Some eye surgeons consider Iols the best option for greatest nearsightedness. Unlike original lens implants, which typically provide clarity in whether near, intermediate, or distance ranges, multifocal and accommodating lens implants offer the anticipation of good vision at more than one range.
Unlike Lasik, surgically implanted lenses do not wish 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 keep enough focusing ability. Convenience and reversibility are just a few of the advantages of this procedure.
