Laser eye surgery vision can still be affected by presbyopia

LASIK Eye Surgery

20th November, 2012  


Laser eye surgery is available to many people who suffer from myopia, hyperopia and astigmatism. As long as your prescription has stayed stable for at least 1-2 years, you don’t have any medical conditions such as diabetes or rheumatoid arthritis and your corneas are thick enough, it is likely that you are eligible for laser eye surgery. If you’re unsure if you would be suitable for eye laser treatment, then book an appointment with yourlaser eye surgery clinic to discuss this with your eye doctor.

There is no age limit as such for eye laser treatment. It is not generally performed on those younger than 18, as there is more of a chance that the prescription will change for children, but even those over the age of 60 can still qualify for treatment.

The procedure is certainly effective in the long term, with people who had the treatment over 10 years ago still reporting good vision. However, your eye doctor may have suggested that you could still need reading glasses later in life, even with laser eye surgery. This may leave you dubious as to how effective the treatment actually is.

the laser reshapes the cornea, which is the transparent outer layer of the eye, to help focus light entering the eye directly onto the retina. This happens by either making the cornea more curved or flatter, depending on which correction is needed. Despite this being an excellent treatment to correct vision, your vision will still deteriorate as you age. This is called presbyopia and cannot be prevented.

Presbyopia onset is usually around age 40, though it can affect some people sooner and is known as early-onset presbyopia. This is basically when the lens of the eye loses its power to focus light properly, which results in deteriorated close vision. This can affect activities such as reading, and is why many people require reading glasses later in life.

Since the cornea is corrected and not the lens, it does not prevent or delay in any way the onset of presbyopia. If you are over 45 years of age and considering laser eye, it may be a good idea to discuss with your eye doctor methods to remedy presbyopia. For example, monovision is a common option, where one eye is corrected for distance vision and one eye is correct for close vision. Also, remember to have regular check-ups with an eye doctor to make sure your eyes are healthy and to detect any early signs of presbyopia.
