What Are The Corrective Eye Surgery Types That Anyone Could Avail?
Nowadays, with the continuous evolvement of modern technologies, even the issue of improving one’s vision isn’t hard to accomplish. In fact, anyone suffering from a refractive or focusing error can now avail various corrective eye surgery types to correct their visual problems.
For those individuals who have been mostly dependent on the wearing of prescription glasses or contact lenses in order to see things clearly at various angles and distances are now ideal candidates for a refractive eye surgery.
Once diagnosed on what type of refractive error one has, the eye doctor will suggest any of these eye correction surgical procedures commonly practiced and recognized worldwide to be among the safest methods of eye surgeries.
- Lasik (Laser In-Situ Keratomileusis)
- Wavefront-Guided Lasik (Custom Lasik)
- PRK (Photorefractive Keratectomy)
What is Lasik eye surgery?
Among the most popular eye surgery methods is the Lasik surgery. It is often advised by eye specialists to patients with refractive problems like nearsightedness, farsightedness and astigmatism. During a Lasik treatment, the eye surgeon uses an excimer laser system to reshape the underlying surface of the cornea. The entire surgical procedure may only take 10-15 minutes and no discomfort can be felt. Patients can even go home afterwards with quick laser eye surgery recovery time where healing process will usually take up to 3-6 months, but functional vision is back within 24 hours or less.
What is Custom Lasik (Wavefront-Guided Lasik) or Advanced Surface Ablation?
Custom Lasik is the newest and most advanced form of correcting a patient with a more complicated case of refractive disorder. The Wavefront-Guided Lasik gives a more accurate measurement of the patient’s optical distortions. With this latest technology, Lasik surgeons can use this as a roadmap to assess the optical map of the eye focusing on the patient’s abnormalities related on how light becomes distorted as it passes into the eye. Another amazing feature of the Custom Lasik is it helps the surgeon make the necessary adjustments on the laser beam settings to arrive at a more detailed procedure. The final outcome for patients choosing a Wavefront-Guided Lasik is sharper and clearer vision with a reduction to nighttime vision difficulties.
What is PRK surgery?
Prk also known as Photorefractive Keratectomy is another laser eye correction that uses the same excimer laser used in a Lasik procedure. In this type of eye surgery, the laser beam is generally used to reshape the cornea by removing the microscopic cornea instead of creating a flap which is done in a Lasik treatment. The PRK surgery uses a computer to check the eye’s surface and get an accurate measurement on the corneal change.
Who are the ideal candidates for these corrective laser eye surgeries such as Lasik, Custom Lasik or PRK?
Based on the guidelines submitted by the FDA, the ideal candidates for Lasik, Custom Lasik or PRK corrective solutions are as follows.
- Individuals must be 18 years old and above with a stable eye prescription for at least a year or two.
- Patient’s refractive error must fall within the acceptable range set for a laser treatment in order for it to become successful.
- Patient must be free from any eye disease, scarring of the cornea or any problems relating to his/her retina.
- Candidate must have a realizable expectation after the eye surgery and be open for further re-treatments in case the surgeon may require one.
The main objective of most patients undergoing a refractive surgery is to completely remove the need to wear prescription glasses or contact lenses and live a normal life with the chance of seeing things in a brighter perspective. Ask your eye doctor what is the most suitable type of eye surgery for your concern.
