Surgical procedures and technology
At the Lumivision Laser Eye Clinic we offer the industry-leading wavefront Lasik performance of the VISX™ Star S4 CustomVue™ system; the first wave front platform FDA-approved for all three prescription types nearsightedness, farsightedness and astigmatism.
This latest generation visx laser platform incorporates dynamic eye tracker, variable beam technology and iris registration to reshape the cornea with extreme precision.
VISX™ Star S4 Smooth Scan Laser
The infrared eye tracking system follows the eye in all three dimensions. The variable spot scanning with its seven variable sized beams allows for faster, smoother and more precise treatment. The Blend Zone feature enables a larger treatment area and is available for those with larger pupil, to minimize night time glare.
The iris registration helps in accurate axis alignment which may occur from sitting to supine position and this is crucial for patients with astigmatism.
LASEK
LASEK is performed by first loosening the skin (the epithelium) on the surface of the eye with a drop of diluted alcohol and gently brushing it aside temporarily. The cool beam of excimer laser reshapes the surface over in few seconds (depend upon individuals prescription) and the skin is rolled back into position.
A contact lens is placed onto the eye for 4 days to reduce any discomfort as the skin (epithelium) heals.This is a procedure of choice in patients with thin cornea and also for patients who are prone to injury from contact sports or trauma and dry eyes.
LASIK
(Laser-Assisted-In-Situ Keratomileusis) is currently one of the most frequently performed elective procedures in most countries including ireland,uk,canada and USA. It is a highly effective outpatient procedure that is suitable for most low, moderate and higher prescriptions. LASIK uses a cool beam of light from the excimer laser to gently reshape the front surface (cornea) of your eye.
The LASIK Procedure:
- Anaesthetic drops are applied to the eye
- A protective flap is created using a micro-keratome and gently lifted by the surgeon, revealing the inner corneal tissue
- Computer-controlled pulses of cool laser light are applied to the inner layers of cornea. The inner corneal layer is reshaped with the laser to mimic your contact lens or glasses prescription
- The surgeon gently replaces the flap and aligns it to its original position. It heals naturally and securely
The laser application takes only a few seconds to a minute depending upon individuals prescription.The entire treatment is completed in less than 15 minutes for both eyes.
Most patients experience a marked improvement in vision within 24 hours. We recommend patients do not return to work until after we have examined them the following day after surgery.
Custom LASIK
Enables your surgeon to further customise the conventional(Premier) LASIK or LASEK procedure to your individual eyes. This customised procedure may result in patients seeing clearer and sharper than ever before. FDA studies show that Custom LASIK may produce better vision than is possible with contact lenses or glasses.In clinical studies, Custom LASIK has been able to provide patients with:
- A greater chance of having 20/20 vision
- The potential for better vision than is possible with contacts or glasses
- Less incidence of glare and halos
- Potentially better overall vision, even at night
Better quality vision
Clinical studies show that Custom LASIK may improve not only what you see but also how well you see it.
With Custom LASIK
Surgeons are able to focus on the quantity as well as the quality of your vision. Many patients who have had Custom LASIK are reporting the ability to see clearer than ever before.
Higher Order Aberrations
Several types of visual imperfections, referred to as lower- and higher-order aberrations, exist within the eye and may affect your vision (the amount of these aberrations vary from person to person). Previously, only lower-order aberrations (such as nearsightedness, farsightedness and astigmatism) could be measured and treated.
Higher-order aberrations may also have a significant impact on vision and have been linked to glare and halos. Now Custom LASIK may help to further customize your treatment of these higher-order aberrations that, in the past, could not be adequately treated with glasses, contacts or conventional LASIK treatments. Your surgeon will recommend the best procedure for you based on your wave scan aberrations measurements.
Custom LASIK
Uses a wavefront analyzer to measure the way light travels through your eye. The wavefront analyzer creates a customized 3-D map of your eye that looks at your entire optical system. This map provides information about the unique visual characteristics of your eye which adds an additional level of data about your vision, enabling surgeon to further customize your vision correction.
Not all patients are suitable for Wave-front treatment particularly those whose pupils are small . Your suitability for this procedure will be assessed at your consultation.
