Presbyopia Correction

Improve Your Vision with Presbyopia Correction

Presphobia Corrective Surgery‘Presbyopia’ is the technical term for Adult Long-Sightedness.  It is an age related reduction in the ability to focus on objects which are too close to the eye, making the image or vision become blurry.  Presbyopia typically affects people over the age of forty.

This is different from Hyperopia, which is the name given to the inability to focus on objects which are close to the eye in people at a young age.  This is a result of the eyeball being shorter than normal.

Many people find Presbyopia very difficult to deal with, as changing from distance to near in everyday life requires people to wear things such as reading glasses.

Those who are Myopic and already need a form of vision correction may now find themselves needing a separate pair of glasses for their near-sighted vision.  

This can effect daily life and may require the person to use glasses more than they would like to view things such as computer monitors, mobile phone screens and messages and so on.

Fortunately, with Presbyopia Correction Treatment, it is possible to correct this condition and improve your vision.

 

Symptoms of Presbyopia

  • Eyestrain, headaches or fatigue when doing close work.
  • Difficulty changing focus from distance to near.
  • Blurred vision at a normal reading distance.
  • Holding reading material at arm's length to see it clearly.

If you notice any of these symptoms if you are over forty years of age, it is quite likely that you suffer from Presbyopia.

 

Causes of Presbyopia

Presbyopia is an age related process which develops as the natural eye lens undergoes changes which make it harder and less elastic.

The ciliary muscles around the lens also weaken with age and are thus unable to contract as and when required.  All of these factors cause the eye lens to lose its elasticity and flexibility over time.

When performing near-by visual work, the eye muscles and lens are used to focus on objects which are close-by, however with the loss of elasticity and flexibility of these muscles and degradation of the lens, the eye is less able to focus on close objects, leading to strain and Presbyopia.

 

Options for Presbyopia Treatment

Corrective spectacle wear for presbyopia correction:

 

Reading Glasses:

Bifocals:

Bifocal is the name given to the spectacle technology which allows for two types of lens within one pair of glasses. 

The upper part of the lens is for the correction of near-sightedness, whilst the lower part is used to treat Presbyopia – these lenses will be unique to each person, depending on the severity of the problem and your optician’s prescription.

 

Varifocals:

These lenses correct Presbyopia in the same manner as Bifocals.

Varifocals are lenses with no visible line that are used to correct distance vision, at arm’s length and close-up viewing.

 

Presbyopia Surgery

Various surgical options for presbyopia correction & repair are available.

Here's a brief look at the options available:

 

Monovision with LASIK:

With the help of laser technology, Monovision will be produced in your eyes.  This means your dominant eye will primarily have far vision, whereas the other eye will have near vision.  

Some ophthalmologist are known to correct one eye to good vision and but intentionally leave the other eye with -0.75D refractive errors during LASIK in preparation of the on-coming presbyopia for their middle age clients.

Others produce a multifocal effect, designed so both eyes can see equally well both far away and up close.

 

Disadvantage of LASIK for Presbyopia:

Once you understand the causes of Presbyopia, you will begin to understand that it is only a temporary solution.  A few years after the LASIK operation, the patient may find their vision deteriorating again due to the natural ageing of their eyes.  

 

Refractive Cataract Surgery:

Refractive Cataract Surgery is the term used to describe modern cataract surgery where the goal is to reduce a person's need for corrective eyeglasses after cataracts are removed.

In the past, most people who had cataract surgery had some near-sightedness, farsightedness or astigmatism remaining after the procedure.

In modern eye surgery, our patients want to be as free from glasses as possible after cataract surgery, and with the use of premium lens implants such as accommodative lenses, multifocal lenses or the Light Adjustable Lens.

 

Refractive Lens Exchange (RLE):

RLE is virtually the same as cataract surgery, but instead of removing a cloudy lens, the surgeon removes the lens from the eye when it is still clear.  

Refractive lens exchange was originally developed to correct large amounts of near-sightedness using traditional monofocal intraocular lenses.

With the development of accommodating IOLs, such as the Crystalens AO and multifocal IOLs, RLE now can correct presbyopia as well.

 

Conductive Keratoplasty (CK):

With controlled radio frequency energy, the collagen around your cornea is shrunk.

Your cornea therefore becomes steeper and your eyeball is lengthened, both of which help to correct presbyopia.

Conductive Keratoplasty, or “CK Surgery” is generally performed in one eye only – A mild laser heat can also be used to perform the same surgery. In that case the surgery is called Laser Thermal Keratoplasty (LTK).

Each lens has its own benefits and suitability for an individual.
