About PRK Surgery
PRK surgery is a type of laser vision correction that treats the surface of the eye. Unlike LASIK Surgery, a corneal flap isn’t made. At EyeSight Hawaii, we use the latest technology for our pre-operative exams and vision correction procedures including LASIK and PRK surgery.
PRK Surgery Pre-Operative Examination
PRK surgery pre-operative examinations are just as important as the actual surgery. During these exams, we gather the information that is used for surgery including measuring corneal thickness and pupil size and dilating the pupils to examine the retina. EyeSight Hawaii is the only laser eye center in Hawaii to perform VISX WaveScan measurements before all laser vision correction procedures. The VISX WaveScan maps your entire visual system in an extremely advanced way that was never before possible and creates a “Fingerprint of your vision”. The WaveScan system produces a very accurate and objective measurement of each patient’s vision which leads to better results.
Laser Vision Correction: PRK Surgery
For LASIK and PRK surgery, we use the VISX Star S4 IR excimer laser, which has the only FDA-approved 3-Dimensional tracking system. There is no need to worry if your eye moves because the laser will follow resulting in more safety and accuracy for the patient.
Numbing drops are used prior to surgery then tiny layers of the cornea are removed. The VISX Star S4 IR excimer laser corrects the vision and then a contact lens is put on the eye which will act as a bandage. This contact is removed about 3-4 days after surgery.
PRK Surgery Post-Operative Examinations
Post-operative exams after PRK Surgery are extremely important. This is when we can see how the eyes are healing. If you ever have any concerns about your PRK surgery, we are more than happy to take a look at your eyes at any time. Full post-operative instructions will be provided to you once a consultation appointment is made and will be discussed during your consultation.
LASIK surgery vs PRK surgery
PRK and LASIK surgery are both laser procedures that correct vision. Both involve a laser to reshape your cornea and the procedure takes just 15 minutes. They both provide great results with low risk of complications.
LASIK is a laser vision correction surgery procedure that permanently changes the shape of the cornea to reduce or eliminate nearsightedness, farsightedness, or mixed visual irregularities due to an abnormal curve in the cornea. LASIK surgery involves creating a flap of the surface of the cornea (the front surface of the eye). Then, the VISX Star S4 IR excimer laser is used to gently and precisely reshape the remaining cornea. Find out more here.
PRK (Photorefractive Keratectomy) is a type of laser vision correction but unlike LASIK, no corneal flap is made. PRK is a surface treatment. Numbing drops are used prior to surgery then tiny layers of the cornea are removed. The VISX Star S4 IR excimer laser corrects the vision and then a contact lens is put on the eye which will act as a bandage. This contact is removed about 3 days after surgery.
In Conclusion, Disadvantages of PRK surgery are more post-operative discomfort, a slower recovery and the risk of hazing on the surface of the eye. PRK is most useful for patients with corneas that are too thin for LASIK, or who are otherwise not candidates for LASIK. Vision with LASIK will be corrected almost instantaneously, there will be little to no pain and full recovery is a few weeks after surgery. With PRK, you may experience blurry vision for a minimum of 4 days after the surgery and full recovery takes about 4-12 weeks after surgery.
