HYPEROPIA AND IT'S DIFFERENT TYPES

 Hyperopia

What is ‘Hyperopia’ or ‘Far-Sightedness’? People who have hyperopia can focus on distant objects but cannot clearly view objects in the near distance. The rays of light come to a focus behind the retina.

What are the causes of Hyperopia? The cause of hyperopia is the failure of the lens to return to its normal rounded shape. Hyperopia is also caused by the eyeball being too short. Both these conditions result in the image being focused on a point behind the retina.

Different types of hyperopia include

Axial hyperopia This condition occurs when the antero-posterior diameter of the eye is too short and the retina is too near the optical system.

Curvature hyperopia– This condition occurs when the curvature of the cornea or the lens is too flap.

Index hyperopia– This condition occurs under any of the following circumstances.

• The refractive index of the aqueous humour is too low.
• The refractive index of the vitreous humour too high or
• The refractive index of the lens is too low.

The absence of the crystalline lens in its normal position in the eye causes high hyperopia which is also called ‘aphakia’.

Symptoms that indicate hyperopia

• Blurring of vision for close work
• Eyestrain
• Headache
• Muscular fatigue, the symptom of eyestrain

Treatments for hyperopia There are a variety of correctional methods for hyperopia. These include

• Spectacles Convex Glasses
• Contact lenses – Soft & Gas Permeable
• Laser surgery for Hyperopia – Lasik & Custom LASIK
• Phakic Intra Ocular Lens – ICL & Phakic & Verisyse Intra Ocular lens
• Refractive Lensectomy

In the hypermetropic LASIK procedure

• The doctor first creates a thin protective flap of corneal tissue using an instrument called the Microkeratome or by using Intralase femtosecond laser (blade-free LASIK).
• He gently lifts this flap, thereby exposing the deeper corneal layers.
• He then removes the tissue from the central and and mid-peripheral portion of the cornea with an Excimer laser.
• This steepens the central corneal curve, refocusing light back on to the retina.
• He gently replaces the protective flap, where it heals naturally and securely.

This procedure is quick, painless and in most cases you can return to your normal activities very quickly, usually within hours.
