    Benefits of Bladeless LASIK

    Last updated 6 years ago

    LASIK surgery has been the vision correction procedure of choice for decades. However, a fairly recent development in LASIK surgery now offers patients more options. Bladeless, also called all-laser LASIK surgery, uses a laser, as opposed to a blade, to make the corneal flap necessary for the procedure.

    To better understand LASIK, it is best to explain that LASIK is a two step process.  LASIK is a type of laser vision correction surgery called “lamellar refractive surgery” because it is performed between the layers of the cornea. Step one of the laser vision correction process involves the creation of a “flap”.  A LASIK flap is a circular strip of the outer corneal tissue dissected away from the underlying corneal layers but left attached in one segment called the hinge. The most common location for the hinge is either the nasal (on the side) or the superior (upper) position.  The LASIK flap is necessary in order to expose the deeper corneal layers to the excimer laser energy that reshapes your cornea to improve your vision.

    Simple Procedure

    The procedure for bladeless LASIK surgery is similar to that for traditional LASIK surgery. However, instead of using the microkeratome blade to create a corneal flap, your doctor will use computer software to guide the femtosecond laser beam and create a corneal flap with a precise depth using millions of microscopic air bubbles. The corneal flap created by the laser has a precise structure and shape that improves how well the flap stays in place.  The doctor calculates the depth of the bubbles in the computer software with the data he/she receives from your preliminary evaluation.

    Fewer Complications

    LASIK procedures with a blade have a low incidence of complications. However, on extremely rare occations, a blade  can create a flap with uneven edges, which can result in abnormal corneal surfaces. Rare incidents of vision-threatening scars can also occur after LASIK has been performed with a blade. With bladeless LASIK, infrared lasers create the corneal flap. The laser divides tissue at a molecular level and works rapidly to create corneal flaps that have more defined and better angled edges, resulting in fewer complications.

    Available to More Patients

    Previously, patients with thin corneas or dry eyes were not candidates for LASIK surgery. However, due to bladeless technology, many more patients are now candidates for LASIK surgery.

    Steps of the PRK Procedure

    Last updated 6 years ago

    Photorefractive Keratectomy (PRK) was the first FDA-approved laser eye surgery. For patients with dry eyes or unusual curvature of the cornea, PRK offers a good laser surgery option. In this video you can learn step-by-step how PRK laser eye surgery is performed.

    First, the outside of the cornea is lifted away, providing room for the excimer laser to reshape the corneal tissue beneath. Once the cornea has been effectively altered, a contact lens is inserted to facilitate healing.

    A Patient's Guide to LASIK Options

    Last updated 6 years ago

    LASIK eye surgery is today’s  preferred vision correction procedure. If you are interested in undergoing LASIK to correct your vision, read on to learn more about your various treatment options:

    LASIK is a two step process.  First we have to get to the cornea, then we have to reshape it. 

    Getting to the cornea can be done in several ways:

    • Microkeratome – bladed mechanical device
    • Femtosecond Laser
    • PRK

    LASIK eye surgery begins with the application of numbing eye drops and the use of a lid holder to keep the eyelids motionless. Next, a flap is created in the front surface of the cornea with the use of an instrument called a microkeratome or a femtosecond laser like the Davinci.  A hinged flap is created to expose the corneal tissue below. 

    Unlike the microkeratome, DaVinci LASIK does not create a corneal flap with a cutting device. Instead, it quickly and accurately creates millions of air bubbles in the front surface of the cornea that overlap to form one large bubble that can then be lifted. Some patients who have been ineligible for LASIK eye surgery due to thin corneas or dry eyes may be candidates for DaVinci LASIK. 

    With PRK, an alcolhol based solution loosens a very thin layer of tissue, which is removed to expose the corneal tissue below.  This tissue will regenerate but will require a couple of additional days of recovery.

    Reshaping the cornea:

    Traditional LASIK Surgery

     The excimer laser used for LASIK utilizes a cool, short beam of light to alter the shape of your cornea, helping you see better without eyeglasses or contacts. The laser has built-in safety features that shut it down if the eye moves during the procedure, ensuring accuracy and safety.

    Zyoptix Customized LASIK

    Zyoptix is a personalized type of LASIK surgery. During the diagnostic process,  our  office utilizes multiple types of testingto develop a specialized treatment plan. The testing  process uses two types of equipment: The Orbscan II collects information on the structure of your cornea, while the Zywave measures your optical system. The data obtained during the testing will be used to determine a treatment plan that is unique to each eye. Zyoptix LASIK offers better-quality results when compared with standard LASIK, particularly for night vision.

    Meet with the experienced ophthalmologists at Clear Advantage to determine which type of LASIK eye surgery is best suited to your needs. Located in Portsmouth, NH, Clear Advantage uses the latest and most advanced LASIK technology to permanently correct your vision.  Call us at (603) 379-6817 to schedule a consultation.
