Your Eyes in Focus
Your eyes are little short of an optical miracle. But if your focus is imperfect (i.e. when the cornea, lens or eye is an irregular shape), light cannot focus accurately on the retina and the image you see is blurred.
Laser eye corrective surgery is ideally suited to the treatment of such conditions.
Your eyes work just like a camera. Light rays pass through the clear part at the front (the cornea) then through the lens, which focuses them onto the "screen" at the back of the eye (the retina). There, millions of photoreceptors (light-sensitive nerve cells) turn the image into electrical impulses that are transmitted to your brain through the optical nerve.
Normal (Emmetropic) Eye
In a normal (emmetropic) eye, the cornea and lens are matched to the length of the eye, focusing light directly on the retina.
This produces a perfectly focused image at all distances.
Shortsightedness (Myopia)
If distant objects are blurred, you may be shortsighted.
In this case your eye is too long, so that rays of light fall in front of the retina and not directly on it. A laser eye operation to correct shortsightedness is possible up to -14.00 at Accuvision.
Longsightedness (Hyperopia)
If close objects are blurred, you may be longsighted.
Your eye is too short, causing incoming light rays to fall behind your retina and not directly on it. A laser eye operation to correct longsightedness is possible up to +8.00 at Accuvision.
Astigmatism
Both shortsighted and longsighted eyes can also have astigmatism.
The cornea is not perfectly round but shaped more like a rugby ball. Therefore, rays of light are bent in different directions and do not form a sharp focus point, resulting in blurred images.
Age Related Longsightedness (Presbyopia)
This occurs in many people as they get older, traditionally requiring reading glasses or bifocal lenses to correct.
The lens in the eye gradually stiffens as it matures and thus loses its ability to accommodate light rays efficiently. Presbyopia Treatments are available that incorporate laser eye corrective surgery from Accuvision which can offer excellent results for people with this condition.
Is Laser Eye Corrective Surgery Right for You?
At Accuvision your safety and total satisfaction are paramount. Laser eye corrective surgery may not be suitable for everyone and a successful outcome is dependent on many factors which must be carefully considered.
Laser Eye Treatment and Eligibility
Whether or not laser treatment can be performed on your eyes depends on a number of factors that need to be assessed by our eyecare specialists at your initial consultation.
Although the majority of people who come to us are eligible for treatment, due to the high prescription levels we are able to treat, we may decline to treat you if the outcome cannot be accurately predicted or if laser eye surgery treatment is likely to cause complications to your sight. Your lifestyle and occupation may also be an important consideration.
In general, the suitability of our laser eye corrective surgery procedures for you depends on factors such as:
- The degree of optical error
- The thickness of your cornea
- The existence of any eye disease
- The size of your pupil
- Corneal mapping data
- Wavefront analysis results
You should ideally be able to answer YES to the following:
- Do you suffer from shortsightedness, longsightedness or astigmatism?
- Are you over 18 years old?
- Is your prescription stable?
- Are your eyes healthy and free from any eye disease?
- Would you rather not wear glasses or contacts on a permanent basis?
Please note that this is only intended as a general guide and there are always exceptions. Detailed analysis of your eligibility for treatment using laser eye corrective surgery can only be achieved at your consultation, but please call us if you wish to discuss the current condition of your eyes and their suitability for treatment on 0845 000 2020.
