cataract surgery

If a person is long-sighted then they can see things at a distance much better than they can see objects which are close to them. They may be able to view television with no trouble, but struggle to focus on a book or photograph they are looking at closely. Commonly, people who suffer from hypermetropia need to use glasses to stop themselves from straining their eyes and suffering from headaches.

Hypermetropia is common in childhood. Due to their smaller than normal eyes, they are particularly susceptible to being long-sighted. In most cases, they grow out of it as their eyes get bigger.

For a person to see clearly, light must be focused to a point at the back of the eye, called the fovea, a part of the retina. If an eye is hypermetropic then it can usually focus the light from far away objects directly into the retina. This results in these objects being seen clearly. Unfortunately, hypermetropic eyes struggle to do the same with objects that are close to them.

Usually, because of the size of the eye, rather than focusing the light from near objects accurately onto the fovea, the light is focused at a point behind the retina. This results in blurred vision because the light is still disjointed and unfocused at the point at which it reaches the fovea.

There are several different ways to treat hypermetropia. ​

The point of focus for objects which are close depends on the relationship between the length of the eye and the strength of the cornea. The length of the eye is a difficult thing to adjust. However, we can adjust the strength of the cornea. The cornea is responsible for up to 80% of the eye’s ability to fine focus. This means that we can achieve excellent results by adjusting the strength of the lens or enhancing its function. This adjustment can be achieved through several different means. ​

We can offer a variety of treatments that can correct long-sightedness. These treatments are usually most suitable for adults between the age of 40 and 60. Between these ages, the eye’s lens naturally begins to lose its flexibility. This loss of flexibility means that the eye’s ability to switch focus becomes increasingly impaired. This process is usually referred to as presbyopia, but the treatments are very similar to hypermetropia.

Laser SurgeryLaser eye surgery is a common treatment for both presbyopia and hypermetropia. This involves using lasers to adjust the focusing ability of the cornea. The best way to find out if you are eligible for laser eye surgery, or whether it is the best option for you, is to go and see one of our eye-care specialists. LASIK eye surgery involves gaining access to and then reshaping the cornea. A small flap is cut on the surface of the cornea so that the cornea can be carefully reshaped. This form of surgery is highly effective in treating cases of both mild degrees of hypermetropia and a moderate degree of myopia.
Conductive KeratoplastyConductive keratoplasty (CK) which works in a very similar way to LASIK surgery reshapes the cornea by using high-frequency radio waves, restoring near vision. Unlike LASIK, CK is not laser-based.

During the CK procedure, your eye surgeon uses a hand-held instrument with a tiny probe (smaller than human hair) to apply low-level, radio frequency (RF) energy to specific spots that form a circular pattern on the outer part of the cornea. Corneal tissues as a result shrink, causing the circular band to act like a belt that “tightens” and steepens the cornea. This change in the curvature of the eye’s surface affects the way light rays enter the eye to bring near vision back into focus.
Phakic LensesPhakic Intraocular Lenses offer very good results without the same hassle and maintenance as contact lenses or even glasses. They are also highly effective in treating extreme cases of hypermetropia. The treatment involves implanting an artificial lens inside the eye which improves the refraction of light. These lenses are improving all the time and producing increasingly promising results.
Refractive Lens ExchangeHere the natural crystalline lens of the eye is removed and replaced with an artificial lens implant, which may be monofocal, multifocal or accommodative, to correct refraction errors. RLE is fundamentally the same as cataract surgery, other than your natural lens is still clear and in cataracts this lens becomes cloudy. RLE is performed primarily to change the refractive properties of the eye, to enable good clear vision without the use of spectacle correction.

There are several lenses available:
Light Adjustable Lens
Accommodative Lenses (Crystals AO)
Multifocal Lenses

If you have been affected by any of the symptoms mentioned above, please don’t hesitate to get in touch.
