Long Sightedness Treatment
Long-sight is a vision disorder that gets increasingly common with age. Longsight is also known as farsight in the United States. The correct medical term is hyperopia.
If the patient suffers from long-sight, it is the close vision that is first affected. Near objects become blurry, such as reading a newspaper or seeing a text or number appear on a mobile phone. This blur for near objects gets worse as the patient ages, and eventually even the far vision can also become blurry.
With long-sight the close vision will always be worse than the distance vision. The name refers to the fact that it is the long sight which is always the better. The patient normally simply wears glasses for reading, particularly in the early stages. Later, the person may graduate to wearing varifocal glasses.
Laser surgery for long sight
Treatment has developed greatly over the past 10 years. Using an excimer laser we can now correct up to 6 dioptres of hyperopia, with or without astigmatism, although correction works best for up to 4 dioptres.
Longsight treatment with our LASIK procedure involves creating a very thin flap using a femtosecond laser, which at Focus is the advanced Ziemer LDV, and then using the WaveLight Allegretto excimer laser to remove tissue in the outer part of the cornea so steepening the central zone. This central steepening makes the cornea into a more powerful lens, compensating for the effects of long-sight.
At Focus, we prefer using LASIK rather than PRK for the correction of hyperopia. Because it is a progressive condition which continues to get worse with age, it is important for the patient to realise that this is not a permanent solution even though they will always retain benefit from having had the treatment. It may be possible to improve the vision further when the patient is older and has more farsight, with a second enhancement procedure.
Hyperopic patients are often the happiest after treatment. This is because higher degrees of this refractive error is a very unpleasant condition, because vision is blurred at every distance. This compares to shortsight, where at least the near vision is in clear focus.
