Lasik and Contact Implants

11 Jan

lens_implantLasik, or laser-assisted in situ keratomileusis, is an operation performed on the eye to treat refractive errors. These are errors in how well the eye focuses and can include nearsightedness, farsightedness or astigmatism. Before Lasik was developed, ophthalmologists actually used to take the cornea out of the eye, freeze it, reshape it and replace it. This was called keratomileusis. In situ means that the reshaping of the cornea can now be done without it being taken out of the patient’s eyeball. Now, the cornea is mapped very precisely and a laser is used to reshape it.

However, there are times when Lasik can’t be used to correct refractive errors. The error might be too large for the surgery to repair. In that case, many patients opt for intraocular contact lenses. These lenses are indeed what they sound like. They’re contact lenses that are inserted into the eye instead of being worn on top of the eyeball like most other contact lenses.

When intraocular contacts like contact implants from Hoopes Vision are inserted, the patient’s real lens is removed. The lens is a transparent structure that’s held within the eye by certain fibers and is full of fibrous cells that are arranged in layers. The intraocular lens that replaces it is made out of very thin and flexible plastic. The surgery is very much like surgery done to remove a cataract, which is a lens that has clouded up and interfered with the patient’s vision.

Like Lasik, contact implant surgery is done after the patient’s eye is numbed by topical anesthesia. The natural lens is simply replaced by an implant that’s been adjusted to give the patient sharp vision. The operation requires no sutures and for the great majority of patients the recovery time is short and recovery is complete. This also includes a noticeable improvement in the patent’s vision. Some people’s recovery is so rapid that they can return to their usual activities even a day after the operation. However, an ophthalmologist might suggest that it’s best for the patient to rest for a day or two.

Before either Lasik or contact implant surgery, the patient will need to be evaluated to see if he or she is a good candidate. The person will need to be free of some conditions or diseases of the eye, be at least 20 years old and enjoy good health overall. Women who are pregnant and are interested in either Lasik or contact implants will need to wait till they give birth to have the procedure done.

People who are interested in learning more about contact implants should get in touch with their ophthalmologist for a consultation.
