Surgical developments have advanced tremendously since the advent of the first eye glasses the thirteenth century ago. Today, developments in vision-correction surgery can minimize or eliminate a person’s dependency on glasses or contact lenses and potentially improve their vision to better than 20/20.
It’s not surprising that people with vision-problems are encouraged by the array of new procedures and technologies. Before choosing which the most optimal vision-correction procedure will work best for you, it’s important to research their advantages and disadvantages. It’s also important to know what to expect before, during and after the procedure. Mostly importantly you must have trust in your vision-correction surgeon. Our doctors undergo extensive training for each vision-correction procedure or technology implemented at the Laser Eye Center. Collectively, the surgeons and staff members have over 15 years of vision-correction procedures in refractive surgery.
Myopia - Short Sighted
Myopia is the term used to define short sightedness. Light from a distant object forms an image before it reaches the retina. This could be because the eye is too long, or the cornea or crystalline lens is too strong.
A myopic person has clear vision when looking at objects close to them, but distant objects will appear blurred.
Myopia is easily corrected at your local Vision Express optician using prescription glasses or contact lenses specifically designed to counteract the effect. A concave lens (minus powered) is placed in front of a myopic eye, moving the image back to the retina and clarifying the image.
Hypermetropia (Hyperopia) - Long Sighted
Hypermetropia means long sight and is where the image of a nearby object is formed behind the retina. This could be because the eye is too short, or the cornea or crystalline lens does not refract the light enough.
A hypermetropic person may have blurred vision when looking at objects close to them, and clearer vision when looking at objects in the distance. By placing a convex (plus powered) lens in front of a hypermetropic eye, the image is moved forward and focuses correctly on the retina.
Presbyopia describes the condition where the eye exhibits a progressively diminished ability to focus on near objects. It is a perfectly natural condition that eventually affects everyone but because the effects are gradual, you may not notice that anything is wrong with your eyesight initially.
However, as the condition progresses, you may find yourself struggling to read small print or books unless they are held at arm's length. With presbyopia, there are many factors (such as deterioration of lens elasticity) that affect the eyes ability to accommodate over varying distances; causing light (and therefore images) to be focused behind the retina. This leads to the eyesight becoming blurred. Presbyopia can be easily corrected with glasses or contact lenses with a combination of options such as, varifocals, bi-focals, separate glasses or mono vision for contact lenses only.
Astigmatism is the optical term for more than one point of focus. It occurs when the surface of the cornea or crystalline lens is not spherical. Light from an object does not focus exactly on the retina but at two separate points. An astigmatic eye has curves that are steeper in one direction than the other. An example of this could be where the cornea is not spherical and shaped more like a rugby ball than football - of course this is not noticeable by just looking at someone's eyes.
As a result, the eye is unable to focus a point or object into a sharp focused image on the retina. There are two types of astigmatism, regular and irregular. Irregular astigmatism is often caused by a corneal scar or scattering in the crystalline lens and cannot be corrected by standard prescription lenses, but may be corrected by contact lenses. Regular astigmatism arising from either the cornea or crystalline lens can be corrected by a toric lens.
A cataract is a clouding of the lens in your eye and can develop in one or both eyes. The lens is normally clear and sits behind the iris – the coloured part of the eye. The lens helps focus light to produce a sharp image on to the retina at the back of the eye and changes shape to allow you to see close objects. A cataract acts like a frosted glass coating that scatters light, causing blurring and lack of clarity.
Cataracts are painless and usually cause a gradual worsening of sight. The main symptoms are:
Blurring: Your vision may become misty or blurry so that you cannot see details at a distance, or your glasses seem scratched and dirty.
Dazzled by lights: You may find that you have poor vision in bright light, suffer from glare, and that bright lights such as car headlights are more blinding than usual.
Double vision: You may start to notice double vision for either close or distance objects.
Changes in colour vision: You may notice that colours appear faded or washed out.
The procedure is conducted not using metal blade. We create customized flap (corneal flap) with high technology of iFS Plus all laser LASIK which has minimal side effects and a quick recovery. LASEK: This procedure is not an alcohol LASEK surgery. We use high technology of Amaris 750s LASEK, which produces less pain, fast recovery and has minimal side effects.
This surgery requires planting a specialized lens for vision correction. The advantage of Implantable contact lens is that it does not damage the cornea during or after the surgery. Patients with high nearsightedness or with very thin cornea, have difficultly receiving LASIK, LASEK or other procedures that involves laser, They may receive implantable contact lens as an alternative.
LBV multifocal laser presbyopia refractive surgery allows you to see the depth of focus. By adding monovision's advantage, It allows patients to see short distance, in-between distance, and all areas of long distances. LBV improves night blindness, blurred light and etc. This procedure has minimal side-effects and increases the quality of everyday life.
Laser surgery involves the removal of the fogged-up lens and replacing it with a new artificial lens. Therefore, this treatment not only improves cataract but also treats myopia, hyperopia, and astigmatism all at once with the highest level of ophthalmic surgery.
