PRK or photorefractive keratectomy is among the safest and most time-tested laser eyesight correction treatments offered. Similar to LASIK, it reshapes the cornea to enhance eyesight. In PRK the surgeon utilizes an excimer laser to vaporize a tiny amount from the surface of the cornea. LASIK, by comparison, cuts an in-depth flap within the cornea utilizing a sharp microkeratome blade. This weakens the actual cornea, can make it hard to switch the flap in exactly the correct spot, and may trigger some other problems such as flap irregularity, epithelial ingrowth as well as corneal ectasia. PRK helps prevent these types of dangers.
What Can I Expect from My PRK Procedure?
Research indicates that 90-95% of people having a correction as high as -6.00 diopters accomplish eyesight of 20/40 following PRK, and as much as 70% accomplish 20/20. People requiring less correction usually attain much better outcomes. The potential risks of PRK include things like infection, haze, gradual healing, scarring, over- or under-correction of the visual condition, as well as growth and development of astigmatism.
PRK eye surgical treatment is an ambulatory treatment, which means it’s executed on a walk-in, walk-out basis. Actually, the surgery usually takes only 15 minutes. You’ll be awake throughout the treatment, however your eye doctor could give you a gentle oral sedative that will help you relax.
Numbing eye drops are placed on your eyes, with an instrument known as a lid speculum is utilized to keep your eye lids wide open. Your doctor then guides the excimer laser over your eye, which is designed to your precise prescription.
You’ll be asked to look at a target light for a small amount of time while your doctor watches your eye by way of a microscope as the laser transmits pulses of light to your cornea.
The laser energy eliminates microscopic levels of tissue and reshapes the cornea. Many people usually do not feel any pain, even though you might feel some pressure in your eye. Your doctor has complete control over the laser and may power it down anytime.
PRK is completed on each eye individually (frequently one by one on the same day), with each treatment taking no more than 5 minutes. Although some people have both eyes handled on the same day, other people decide to have the surgery on their second eye one or two weeks later.
Your doctor covers the treated cornea using a bandage contact lens. Within just days, new epithelial tissue grow back, and the bandage contact is taken off.
