>>About Hyperopia
Hyperopia or Long sightedness, is a common vision problem, affecting almost a fourth of the population. People with hyperopia can see distant objects clearly but have difficulty seeing objects that are near. Long sightedness or hyperopia, occurs if a persons eyeball is too short or when the cornea is too flat when compared to the normal eye. The light entering the eye focuses behind the retina, instead of directly on it hence close objects look blurred. Young people with mild to moderate hyperopia are often able to see clearly because their eyes can adjust, or accommodate to increase the eye's focusing ability. However, at later years the eye gradually loses the ability to accommodate and blurred vision becomes more apparent.



>>What are the causes of Hyperopia ?
* Long-sightedness is often present from birth, when the eyeball is short or the lens is too weak compared to the normal eye.
* Family history also contributes to long sightedness.
* Long sighted patients have a blurred vision of close objects.
* They suffer from eye strain and headache after doing close work.
* Iritability and nervousness after prolonged concentration.


>>How can we diagnose Hyperopia ?
Hyperopia can be diagnosed by general eye examination.


>>How can Hyperopia be treated ?
The treatment for hyperopia depends on several factors such as the patient's age, activities, and occupation. EYEGLASSES: Glasses (spectacles) or contact lenses are the most common method used to correct most long-sightedness. A person may need to wear glasses, only when reading , working on a computer or while doing other close work. Some patients may have to wear it constantly.
SURGICAL OPERATIONS: Refractive surgery is another option for correcting hyperopia. It may reduce or eliminate your need to wear glasses or contact lenses.
USES OF EXIMER LASER: In LASIK, (laser-assisted insitu keratimileusis) a thin layer of the cornea is cut and gently lifted then laser is used to reshape the cornea. The corneal flap is carefully repositioned. This procedure allows light to focus more precisely on the retina, resulting in clearer vision.
CLR (Clear Lens Replacement): In this topical drops are given to make the eye numb. The natural lens is gently removed with ultrasound and replaced with an intraocular lens of desired power.
LTK (Laser Thermal Keratoplasty): It is a non-contact procedure that utilizes a beam of laser energy to shrink the fibers of the cornea, makes the outer surface of the eye more steep and images appear more sharp.
ICLs (Implantable Contact Lenses ): It is the implantation of plastic corneal rings, which also alter the shape of the cornea.
