Advanced PRK

What Is Advanced PRK In New York, Manhattan, NY?

PRK, which stands for photorefractive keratectomy, is a type of refractive eye surgery that is used to correct mild to moderate nearsightedness, farsightedness, and astigmatism through the use of a laser. When the laser is directed over the eye, our ophthalmologist can change the shape of the cornea to alter how light is focused on the retina to improve vision. PRK can limit how often you need to wear glasses or contacts, or it could eliminate the need for them completely. Since the laser targets the surface of the eye directly to modify the shape of the cornea, PRK may be the better option for those patients with thinner corneas, irregular or scarred corneas, or a history of dry eye.

Getting Advanced PRK

Even with advanced PRK technology, it is important to understand what this procedure can and can’t do. This is why our ophthalmologist will discuss in detail your treatment goals as well as your lifestyle to determine whether PRK is a good option for you. PRK allows people to perform many of their everyday routines without resorting to contact lenses or glasses; however, there are certain tasks such as reading or driving, where you may still need your glasses.

If you’re deemed an ideal candidate for PRK, this procedure is performed right here in our office as a simple outpatient procedure, which means that you will be able to go home the very same day. The advanced PRK procedure only takes about 15 minutes. Eye drops will be placed in the eyes to numb them. Next, a special solution or brush is used to remove the epithelium, the outer layer of cells on the cornea. From there, you will be instructed to look at a light, which our eye doctor will use to shape the cornea. Once the procedure is complete, your doctor will place a protective contact lens over the eye.

Vision will not be perfect immediately after the procedure. During your healing time (7 days), it is common to experience blurriness, light sensitivity, dryness, and grittiness. As healing occurs, your vision will get better.  It is recommended to rest for the first 2 days when both eyes are treated together and oral pain medication, as well as topical eye drops, will be given to keep you comfortable. Newer PRK techniques we now use have shortened the recovery time from some of the older methods. Your vision may slightly fluctuate over the next few weeks to months before optimal vision is reached.

Candidates for Advanced PRK

Patients who are ideal candidates for PRK will be at least 18 years old, have a stable eye prescription that hasn’t changed in a year and have healthy corneas. Those patients who lead an active lifestyle may be better candidates for PRK over LASIK surgery because PRK does not require making a micro-flap in the cornea, which could later become dislodged during certain intense physical activities.

  • "Cannot recommend Dr Coad & his lasik coordinator Nicole enough. They are wonderfully supportive and gentle that even if you are nervous it will be difficult to stay that way around this supportive duo! Without a doubt recommend going to see them, they are worth the additional care and cost for a full-service experience that are there just to help you & give you the best vision possible. Thank you Dr Coad & Nicole."

  • "Dr. Coad and his staff made the experience of having a cataract removed the best it could possibly be, from evaluation to discussing options to being reassuring when the surgery began, to follow-up. The evaluation process was efficient, yet at no time did I feel as if it was anything but personal. His staff at all times were both professional and welcoming. Vace, the surgical coordinator, did everything to make sure the surgical process went smoothly.
    As to Dr. Coad himself, I can't say enough. His skill is absolutely top-notch, but it was the concern that he took in making sure that I understood all of my options, and his reassuring manner before, during and after the surgery which makes it easy to recommend him to the fullest to anyone who needs ophthalmic care."

  • "Had a five star experience at Chelsea Eye! I went to Dr Yoon for an eye exam and she was extremely friendly, helpful and down to earth! I have met all the staff and they are very friendly and easy to talk to. Hugo in particular was wonderful to work with during the exam. It was a breathe of fresh air coming to this practice and I highly recommend going here for an Optometry appointment or Opthalmology appointment with Dr Coad."

  • "Can I please take a moment and talk about how awesome Dr. Jay Yoon is?!

    I would be friends with this woman! I went in freaked out about a blood vessel on my eye and in total hypochondriac mode (is it a stroke? Is this connected to my brain? Is it gonna spread?). She laughed and calmly said "looks like you've always had this and it's fine and here are some drops cause your eyes are dry and here's my great primary doctor who I recommend since you don't have one."

    She was very funny and relatable and cool - she didn't try to rush me away and she was honest about everything too and so helpful.

    I've already started recommending her and now I'll do it on here: book an appt and be treated so warmly."

  • "Dr Coad and Nicole were both absolutely wonderful. After my brother had LASIK surgery, I decided to go ahead and do the same.

    Both Nicole and Dr. Coad are very proficient in their work. They answered any and all questions that I had, and calmed every nervous feeling that arose from the start, up until the surgery.

    Going through the surgery I was EXTREMELY nervous and Dr. Coad walked me through the entire procedure (before and during) and made my whole LASIK experience a breeze.

    I can not recommend them enough. If you are interested in LASIK Dr. Coad is the only doctor I would trust."

  • "This team is the absolute best. Christine is a gift from the gods and makes you feel comfortable supported and amazing. She really got me through my anxieties about my recent lasik surgery - which went great! Dr Coad is the best. A fantastic team, a simple process - I highly recommend this team - if you've ever considered lasik (like I have for the last 20 years) make an appt with this great group. You'll be happy you did."
