Many people are tired of wearing glasses or putting in those contacts on a regular basis, so they decide that laser surgery might be the right option to get their vision corrected once and for all. However, many people do not realize that laser surgery might not completely remove the need for external devices. After seeing your Traverse Vision Midland optometrist, it will be possible to determine whether or not laser surgery will likely take care of your vision correction needs.
Laser surgery to correct farsightedness, nearsightedness, and astigmatism was inaugurated in the 1990’s. It is performed by an ophthalmologist, (an M.D. with special training who performs eye surgery), generally a referral from their Midland optometrist. There are two common types of laser surgery done to correct vision. Lasik is the traditional and more common type where the ophthalmologist cuts into the cornea and makes a flap on the surface. The surgeon then reshapes the cornea using a laser to correct the vision problem and return the eye to what is considered perfect vision at 20/20 to 20/40.
The second type of surgery is called PRK or photorefractive keratectomy. In this technique, micro-fine layers of the outer cornea are scraped off instead of making a flap, and then correction to the cornea is made. Research has shown that nine out of ten people who undergo this surgery return to vision between 20/20 and 20/40. These ratings are considered perfect and near perfect respectively and typically patients do not need external vision correction like glasses or contacts following the procedure.
However, it is important to know that your chances of a completely successful vision correction surgery that requires no glasses or contacts drops after the age of forty. A condition called presbyopia, the normal loss of the ability to focus well on objects at close range, continues to increase with age. Laser surgery is unable to correct presbyopia or prevent it from occurring in the future. Thus, people forty and over have likely begun to experience this phenomenon and may have to still wear glasses or contacts to focus on objects up close. This is the same reason many people end up needing reading glasses as they get older. It is possible that even after surgery, your Midland optometrist will still need to prescribe glasses to be worn when reading or viewing close objects. Many people consider this a tremendous benefit and an alternative to having to wear glasses or contacts all the time. However, if you are in a profession (or have an avocation) that requires viewing things regularly up close, it may not be worth having the surgery.
