Many patients at SightMD know that they want laser vision correction by our board certified LASIK doctors and LASIK surgeons. Patients arrive for their free LASIK consultation with questions about which laser eye surgery procedure is best and safest for them.

Our board-certified eye doctors and eye surgeons are pleased to answer your questions and keep our patients informed about their options. In some cases, we may decide that a patient would be better off with a procedure known as PRK.


There are certain clinical findings that might make a patient better suited for a surface laser vision correction procedure. Advanced surface ablation, also called PRK, LASEK,  Epi-LASIK, or Photorefractive keratectomy, delivers the laser vision correction part of LASIK right on the surface of the cornea without a flap.

By not making a flap, the correction is placed more superficial in the cornea. About 30% of the patients at SightMD have surface laser vision correction.

PRK is safer for patients who have thinner corneas. This is because during LASIK, corneal tissue is removed. If you have thinner corneas, removing even a small amount of corneal tissue could prove devastating! PRK delivers comparable results to LASIK, without needing to remove any tissue from the cornea.


This may be safer for patients with thin corneas, irregular corneas, high prescriptions, dry eyes and a few other clinical conditions. Surface laser vision correction is more advantageous when staying more superficial in the cornea is important.

To be a good PRK candidate, you’ll still need to keep some of the factors of LASIK candidacy in mind. You must be at least 18 years old and have a stable prescription for a year. You also need to be in good health and not have any current eye conditions. If you have a condition like dry eye, it needs to be fully under control before you can undergo PRK.


Surface laser vision correction delivers the same excellent results, but there can be more discomfort in the first few days. The final visual result arrives less quickly as well. Our doctors tell our surface laser eye surgery patients that they will get the same results as LASIK, but they have to wait longer and will have more postoperative discomfort in most cases. With PRK, you’ll also have a longer recovery period than LASIK. This is because during the procedure, the full epithelial layer is removed from the eye. It can take several weeks for that layer to grow back. As a result, you may have blurry or distorted vision for a few weeks after PRK but it’s temporary. Once recovered, you’ll notice clearer, more beautiful vision!


LASIK which describes a procedure that involves making a flap in the superficial layers of the cornea and then placing the laser vision correction ablation under the flap. About 70% of our patients at SightMD qualify for LASIK. LASIK is the most popular elective surgery you can undergo and with good reason! If you’re a candidate for LASIK, you can say goodbye to glasses and contacts and say hello to clear vision! LASIK is all about giving our patients the visual freedom they’ve always craved.


Patients like LASIK because the visual recovery is quick and painless in most cases. LASIK patients drive to our LASIK centers the very next day for their post-operative exam, in most every case.

With LASIK, many patients see results almost immediately after the procedure. If you don’t, that’s normal too! Your vision may seem smoky or hazy, as well as blurry.

This is only temporary, and will go away as your vision continues to improve and clear up. Your eyes may feel dry or scratchy as well. Within a few days, this will usually go away. You’ll need to be extra careful with your eyes after LASIK.

This means avoiding strenuous exercise, lifting, or dangerous activities. The flap in your cornea is delicate and needs to be given enough time to heal. After the first month, your vision will be stable and you’ll likely have 20/20 vision, if not better! Most side effects go away at this time as well, leaving only clear vision as far as the eye can see.


Our patients have enjoyed the very best in LASIK technology including all blade-free or bladeless LASIK with IntraLase®, the safest and most precise way to make a flap. Our LASIK surgeons also use iDESIGN custom LASIK corrections using the WaveScan WaveFront™ to create a waveprint or wavemap. A wavemap is like a fingerprint of your visual system. In this way, every correction is unique for that patient allowing us the most accurate results possible. This correction automatically centers and automatically tracks your eye movements during LASIK surgery and also uses iris registration. Iris registration uses the unique landmarks of your iris to precisely place the vision correction procedure.
