If you’re tired of wearing contacts or glasses there are a number of different types of corrective laser surgery.
Here at Ashfield Eye Clinic, we recommend Photorefractive Keratoplasty, or PRK. PRK uses the latest innovations in laser technology and is a fast, safe and effective solution for a number of vision problems.
What is PRK?
If your doctor decides you’re a good candidate for PRK he will use excimer laser technology on the surface of the eye to reshape the cornea. The laser beam is computer guided based on parameters, or measurements of your eye and its shape.
Who is suitable?
Dr Den and his staff will first assess your general health history, and eye health to determine if you’re right for this procedure. You’re probably suitable for PRK if you’re over 18 with a refractive error of between -9 and +3 and have astigmatism. For patients who aren’t suited to this technique there are a number of alternatives, including intraocular lens surgery.
Advances in laser technology now allow us to treat the cornea with pinpoint accuracy. You may have heard of LASIK, a technique utilised successfully by other surgeons, which involves cutting into the cornea. This is no longer necessary with advanced PRK techniques. This means that the procedure is simpler, and many complications are reduced or eliminated altogether. Some of the problems eliminated by the PRK procedure include incomplete flap, buttonhole, chronic dry eye syndrome, retinal detachment and interface keratitis.
What does the procedure involve?
The PRK procedure lasts about 10 minutes for each eye. The area is completely numbed beforehand with anaesthetic eye drops. A plastic drape and a soft speculum are used to hold the eye open to ensure there’s no blinking. Then the cornea is gently wiped with a damp sponge to remove excess moisture in preparation for the procedure.
During the procedure, the laser is used for a very brief time, about 10 to 50 seconds. During this time, the patient looks at a small target light, and the laser software tracks any eye movements to the treatment is applied in the right area. Afterwards, a sponge soaked in a special antibiotic is then placed on the eye for a short period. This helps to ensure a good outcome to the procedure. The eye is then rinsed and a specially designed contact lens is placed on the surface of the eye for comfort and protection.
How does recovery take place?
The contact lens is left in place for 4 days after the procedure to allow for healing to take place. During this period, the eyes are sensitive to light and it is recommended that you stay mainly indoors. Medication is given for discomfort and to assist with sleep and with healing.
After this period, the patient is reviewed and the contact lens removed. The vision is generally dramatically better at this stage and then continues to improve back to sharp vision in 1-3 weeks. Generally one will required a week off work following the procedure, depending on your occupation.
