In a normal (emmetropic) eye the light is focused on retina (fovea). In presence of refractive error the light is focused in front of retina ( Short sightedness/myopia) or behind the retina (Longsightedness/hypermetropia).
It may also not form a point or circular focus but form a line focus called astigmatism which can be in front or behind the retina or mixed. In presence of refractive error the image visualised is blurred.
The Excimer laser removes the corneal tissue and aims to neutralise the refractive error significantly by reshaping the cornea, thus reducing or eliminating the refractive error/ blur vision.
You must be at least 21 years of age with healthy eyes & wear glasses or contact lenses for distance vision with a stable refraction. You must fall within treatment parameters and protocols of our clinic & have realistic expectations with good general health.
LASIK is not the only type of refractive surgery available to patients. Although you may not be eligible for LASIK, you may be eligible for a different procedure. You will need to discuss your options with your ophthalmologist. For more information on these options, please have a consultation with our experienced surgeon.
The primary objective of the consultation is to determine whether you are a candidate for laser vision correction, and if so, which procedure is most appropriate for you. Learning everything you can about your options is the key to making an informed decision. We will help you understand what results you can reasonably expect after the procedure given your particular prescription and circumstances.
If you schedule a consultation, there is no obligation to move forward with the procedure.It is important for you to realise that even if it is determined that you are not a candidate today, it does not mean that you will not be a candidate in the future. The technology for vision correction is constantly being enhanced, enabling higher and more difficult prescriptions to be qualified.
However, laser vision correction is not for everyone, and some patients (those with certain diseases of the eye involving the cornea and retina) will never be candidates. The best way to find out more is by having a free consultation at Lumivision laser eye clinic.
Reduce or eliminate dependence on glasses. Ability to play sports unhindered. Improved appearance and confidence.
One year after treatment over 95% of people with low to moderate prescriptions are able to pass a driving license vision test without corrective lenses.
Yes, you can have bilateral simultaneous LASIK (both eyes done at the same time). In fact, the practice is common. We are happy to treat each eye individually on separate visits if patient requests. Patients should discuss their options with their surgeon.
The procedure is performed using anaesthetic drops which numb the eye. One can experience the stretch or discomfort on lid from speculum and sensation of pressure from suction ring when the vision fades but the laser do not cause any pain or discomfort. From our experience most patient says that there is no pain but it is overall very strange experience.
Yes. 5-year follow-up studies indicate that after the healing process is complete your vision remains stable. Lasik is a surgical procedure that permanently removes corneal tissue to reshape the cornea in order to improve refraction. The physical results are permanent.
Laser vision correction cannot prevent the natural ageing changes within the eye and if you are over 40yrs of age than reading glasses may be required for near vision. It may be possible to have monovision treatment for selected suitable patients after full counselling. This can correct for distance vision in one eye (normally the dominant eye) and reading vision in the other.
Depending on the cause, retreatment is possible but you would need to see your lasik surgeon to determine the cause of the change and to determine which option is best for you.
After LASIK your eye should be white and clear the next day in most cases and some can see red spot on white surface which occurs from suction pressure on small blood vessels and normally disappear in a week. The healing process can take 4-5 days with LASEK and the eye may appear red.
Most LASIK patients can return to all normal activity within 2 to 3 days. We advise LASEK patients to be off work for one week.
