The different sorts of LASIK Surgery
The PRK and LASIK eye surgeries would be the two surgeries performed with varying forms of modifications. Whichever procedure is performed within the Lasik surgery clinic, the patient remains awake while drops are put within the eye for your numbing effect.

Under the PRK category, these surgeries all involve using an ablation technique that removes only the outermost layer utilizing a rf laser. The cornea is then reshaped having an excimer laser that uses UV light to cause tissue to disintegrate instead of burning it well.
Other sorts of laser surgery by using this surface ablation technique would be the PRK (Photorefractive Keratectomy). This method involves manually scraping away the epithelium with the cornea. The excimer laser then reshapes the tissue which is located underneath the top of the cornea. The epithelium layer will come back and also this procedure works well for patients that have a skinny cornea. This may be more difficult to heal and is also more painful. The potential risk of an inner eye pressure pushing out which in turn causes a bulge having a worsening in vision, is kept to a minimum because the PRK doesn't penetrate deep enough in to the cornea.

LASEK (Laser Assisted Sub-Epithelial Keratomileussis) is another approach to PRK that utilizes alcohol solution that softens and removes the epithelium. The excimer laser then reshapes the framework of cells and ligament. The epithelium is then replaced. This action does heal faster than the PRK.
The Epi-LASIK is a similar procedure towards the LASIK and runs on the separator in order to save a full time income layer with the epithelium. This really is replaced following your excimer laser has reshaped the connective tissue. This assists in easing pain and supports the recovery process, a lot more so than LASIK.
The LASIK (Laser-Assisted In Situ Keratomileusis) works with a microkeratome metal blade to cut the corneal flap and also the excimer laser to reshape a person's eye. The flap is then placed back over the cornea. This is usually a painless procedure and answers are immediate. There could be some blurriness for your first day and vision is constantly improve over a few weeks.
The Custom Vue Lasik uses the same equipment as the regular Lasik does. Wavefront software guides the excimer laser for further precise measurements. This equipment piece measures and maps the vision and optical arena with a lot more accurate data and techniques.
The Conventional IntraLasik uses a femtosecond Intralase laser that produces the corneal flap. A lot thinner flap is manufactured plus it eliminates imperfections that can be caused by metal blades. It is a far better system for your flap creation. It will take approximately 1 minute many is more expensive.
The Custom Vue IntraLasik laser eye surgery combines good luck rolled into this one surgery. It uses the laser for that cornea flap as well as the Waterfront technology to guide the excimer laser. Needless to say, this is actually the most expensive procedure.
A number of the LASIK negative effects are unwanted visual effects such as sensitivity to light, how each eye refracts light, as well as differences in how each eye perceives the dimensions of objects.
The laser surgery risks can include blurred vision as a result of tiny imperfections within the corneal tissues plus a insufficient defined edges which was obtained with previously corrective lenses. Risks are relative few for many patients.
