Presbyopia or adult longsightedness is an age related reduction in the ability to focus on objects too close to them as the image appears blurred.
Presbyopia typically affects people who are 40 years and older. This is different from hyperopia, which are people whom are not able to focus on near objects at a young age as a result of their eyeball being shorter than normal.
Many people find presbyopia very difficult, as changing from distance to near in everyday life requires the dreaded reading glasses. For those who are myopic and already need vision correction for distance, may now need a separate pair of glasses for near vision. This is especially inconvenient as work often requires them to use the computers, read their mobile phone messages and so on.
Fortunately, with presbyopia correction, it is possible to treat this condition and improve your vision.
If you notice any of these symptoms if you are over 40 years of age, it is quite likely that you suffer from presbyopia.
Presbyopia is an age related process. The natural lens undergoes changes maker the lens harder and less elastic.The ciliary muscles around the lens also weaken with age and are thus unable to contract as required. All these factors cause the eye lens to lose its elasticity and flexibility. When performing near visual work, the lens and muscles has to be more flexible to focus on near objects. As a result of the loss of elasticity and flexibility, the eye is unable to focus on close objects, thus leading to presbyopia.
Corrective spectacle wear for presbyopic correction:
Various surgical options for presbyopia correction & repair are available nowadays. Here's a brief look at them:
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 ageing of their eyes. Their option then would be to put on glasses again, or go for LASIK again.
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 nearsightedness, 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.
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 nearsightedness using traditional monofocal intraocular lenses. But with the development of accommodating IOLs , such as the Crystalens AO and multifocal IOLs, RLE now can correct presbyopia as well.
With controlled radio frequency energy, the collagen around your cornea is shrunk. Your cornea thus becomes steeper and your eyeball is lengthened, both of which help to correct presbyopia. CK surgery is generally performed in one eye only. 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. Contact one of our specialists to see how we can help you.
