Implanted Contact Lenses: What Are They?

The most general form of correcting sight surgically involves reshaping the cornea (front of the eye) with a laser (e.g

. PRK or lasik). Those who will not meet the stringent criteria essential by laser eye treatment like this would find other methods to be more appropriate for them.

One alternative would be implantable contact lenses. For this surgery, a premade plastic contact lens would fundamentally be placed within the eye. Don't mistake implantable contact lenses with the conventional ones that individuals often use on a daily basis as an option to glasses. Implantable contact lenses are designed to sit between the iris (coloured part of the eye) and the natural lens within the eye.

They are shaped with wings to keep it in place and for them to sit flawlessly in the eye. Equipped with the specific power essential to rectify your sight, the center of the lens is round in shape. The glasses prescription calculated before the operation begins determines the power.

A local anaesthetic is necessary to introduce this thin piece of plastic into the eye. To soothe patients' nerves, mild sedatives can also be taken orally while the brief procedure takes place. To enlarge the pupils and dilate the hole where the implantable contact lens will be placed, another eye drop will be used; between the iris and lens.

Roughly 3mm in length, there would be two minuscule incisions to be made at the edge of the cornea. The implantable contact lens is slipped into this minuscule incision with a mechanism which rolls up the artificial lens. The contact lens, once within the eye, is ejected out of the implantation mechanism unfolded. The precise orientation is done with a metal prong inserted into the second incision, as the lens is maneuvered to sit behind the iris.

The surgical process takes approximately 30 minutes in total.

The corneal incisions cure promptly on their own so no stitches are required. Soon after the operation, filmy shields will be set over the eyes which should be removed the following day.

There are a number of advantages to implantable contact lenses over conventional laser eye treatments such as lasik.

For instance, lasik cannot be performed on thin corneas as it involves reshaping the cornea so enough thickness is essential. Lasik also cannot be performed for those with moderate to elevated amounts of myopia (shortsightedness) or astigmatism as more of the cornea needs to be removed. An option then, would be implanted contact lenses.

Should the prescription modify after the procedure, the implantable contact lens can still be removed and replaced with a brand new one. This surgery can be performed many times. Lasik can only be done for a limited number of times as the cornea becomes thinner with each operation.

Nowadays, implantable contact lenses are becoming an increasingly normal refractive surgical procedure. As materials and lenses continue to bebetter and designed, this may very well be the touchstone in sight improved in the future.
