Visx Custom Vue LASIK Laser Procedure for Hyperopia Dr Vidushi Sharma SuVi Eye Kota India.mpg

This video illiustrate management of hyperopia (plus 6 diopter) by AMO Visx Custom Vue Lasik Laser procedure performed by Dr Vidushi Sharma & Dr Suresh K Pandey at SuVi Eye Institute & Lasik Laser Center, Kota, India. Installed as first machine in the state of Rajasthan, the AMO Visx Star S4 IR CustomVue Lasik Laser procedure is the first U.S. approved wavefront-guided laser treatment for hyperopia. LASIK is a recently developed operation, which can correct both long and short sightedness and also astigmatism. An excimer laser is used to sculpt the cornea to a new curvature that will correct the optical defect.LASIK surgery is carried out with a local anaesthetic (eye drops). A small metal suction ring is placed on the surface of the eye around the cornea. This stabilises a cutting device (microkeratome) that shaves 130 (or less based on corneal thickness) microns of tissue from the surface of the cornea to create a very thin flap. The microkeratome (ML7 in this video) and metal suction ring are then removed from the eye and the tissue flap is temporarily folded to one side. The exposed area of cornea is sculpted by an AMO Visx Star S4 IR excimer laser and steepened centrally. The laser treatment takes 3 or 4 minutes to complete, after which the flap of corneal tissue is folded back and a plastic shield protects the eye. LASIK is a modification of PRK in which a tissue flap covers the laser-treated area. There is no raw area of cornea exposed at the end of the operation, and so little or no pain after the surgery, and the eye settles down much more quickly. The optical recovery is faster and the vision generally stabilises rapidly. It is rare to encounter scarring in the visual axis after LASIK. The amount of corneal tissue that can safely be removed by the laser is limited by the thickness of the cornea. To minimise the amount of tissue that needs to be removed by the laser, the optical correction is restricted to a small central area of the cornea. It can be seen from the diagram that the optically corrected area is generally smaller than that achieved by a contact lens. Provided that the treated area is directly over the pupil then the optical performance of the eye is satisfactory. If the pupil is very large (e.g. when driving at night) then the light rays may pass through both optically corrected and uncorrected parts of the cornea and this can lead to glare and poor vision. If the optical area treated is not perfectly centred on the pupil the quality of vision may also be reduced. If the strength of the optical correction achieved by the treatment is inaccurate, it is possible to carry out further treatment by lifting the flap and applying additional laser to the bed. A small optical correction requires less laser treatment than a larger correction. The greater the refractive error that is being corrected the greater the chance of a less than perfect outcome. The combination of an experienced LASIK surgeon, state-of-the-art technology, careful preoperative selection, and attention to detail greatly enhance the success rate of Lasik surgical operation. We have had the opportunity to evaluate every technology available and ultimately chose to invest in and have the most experience with the VISX STAR S4 excimer laser, which is also the most popular laser in the United States. The VISX, used at SuVi Eye Institute Kota India, has advanced scanning capabilities, as well as three-dimensional infrared eye tracking to ensure that minor eye movements will not interfere with the quality of the custom LASIK treatment. In addition, we are the first Center in Rajasthan, India that utilizes state-of-the art Visx Customvue wave front technology with Iris Registration, which allows us to correct complex refractive disorders, not just nearsightedness. In fact, VISX CustomVue™ technology can identify, measure, and treat imperfections in the human visual system 25 times more precisely than standard methods.
