PRK laser eye surgery can be used to correct nearsightedness, farsightedness, and astigmatism by removing surface cells of the cornea. Traditional laser correction works on the tissue within the cornea by using a computer to control pulses. PRK eye surgery stands for photo refractive keratectomy, a type of surgery that is recommended for some individuals based upon the makeup of the eye's anatomy. This procedure requires removal of some surface cells within the cornea without blades and may be more painful than traditional laser surgery. Many people want the freedom of being able to see without the use of glasses or contacts. Advances in technology have made this possible and technology is continuing to provide individuals with options over using eyewear.
There are multiple procedures available for correcting vision and an ophthalmologist will want to perform an examination in order to recommend which procedure will work best for the patient. PRK laser eye surgery may seem a little dangerous when thinking about what is actually being done to the eye, but choosing a specialist that is experienced will help to set one's mind at ease. To be eligible for the procedure, patients must be in good health with no major health problems that affect vision. Illnesses that can affect vision include diabetes, rheumatoid arthritis, overactive thyroid, hardening of the arteries, high blood pressure, leukemia, among others. An ophthalmologist will need to know all the medicines that are taken by the patient because certain prescription drugs can affect vision. Viruses in the body can also affect vision including, herpes virus, and syphilis infections.
Using a high-powered telescope, an ophthalmologist can capture tiny imperfections within the cornea. The data is fed into the laser to develop an individualized treatment plan. The technology can be used to customize PRK eye surgery and correct the tiniest vision problem. Some of the imperfections with vision are not correctable by using glasses or contacts but customizable procedures can improve vision to the smallest detail. PRK laser eye surgery does not require any injections but drops that contain anesthesia are used to numb the eye before the procedure is done. Healing time for photo refractive keratectomy is longer than traditional laser correction because of the location of the correction within the cornea. Improvements in vision may be more gradual than traditional procedures.
Ophthalmologist will usually require that the candidate for a procedure have a stable vision prescription for at least one year. Young adults may experience changes as they mature so doing PRK eye surgery too soon might mean that it will have to be done again later. Since hormonal changes can affect sight, most specialists won't perform the procedure on women who are pregnant. Candidates that have extremely dry eyes are not good candidates because the procedure can make this condition worse. Those who have undesirable risks to PRK laser eye surgery might want to consider implantable lenses. Implantable lenses are surgically implanted within the cornea altering the way light rays enter the eye. At this time implantable lenses can only be used for candidates who are near-sighted.
The options today for improving sight are very promising as research continues to make new options available. Even patients with eye problems such as glaucoma, macular degeneration, cataracts, and other diseases can benefit from new technology. It can be very discouraging to not be able to take advantage of current PRK eye surgery because of an illness but there may be other options for individuals who suffer with these kinds of problems. Fear of trying something new can make one apprehensive. Trusting in God and having the faith in Him to guide one down the best path in life can bring rejoicing. "For our heart shall rejoice in Him, because we have trusted in His holy name" (Psalm 33:21). God's Word offers great and precious promises that give His children hope and peace in the midst of life's troubles and uncertain circumstances. If one procedure isn't the answer, consider some of the other options available to achieve better sight.
People who are skeptical about having vision corrective surgery may want to consider other options to correct vision. Some of the contact lens technology today has created a lens made of a substance that makes it possible to wear them up to 30 days without taking them out. This provides some freedom and flexibility but not as much as prk eye surgery would provide. It is also important to consider that corrective procedures won't correct deterioration of focusing abilities associated with aging. Even after a corrective procedure it may still be necessary to wear reading glasses. If the patient decides to try monovision, then reading glasses might be eliminated. Monovision means that one eye is corrected for distance and the other is corrected for reading or close up work. Monovision can be simulated with contacts before PRK laser eye surgery is performed, so the patient can see if it is a desirable option.
