James Ball discusses the causes of presbyopia and whether it can be prevented.
We use PRESBYOND ™ laser eye surgery to correct presbyopia. Though it cannot restore distance vision and near vision in the same eye, laser eye surgery can correct presbyopia by using the PRESBYOND ™ blended vision technique.
The majority of people in their forties and fifties who need glasses for distance and reading are suitable for PRESBYOND ™ blended vision laser eye surgery. As part of our comprehensive assessment of your vision we simulate the effect of the PRESBYOND ™ and can predict your tolerance to the blended vision optical set-up.
The majority of clinics only offer lens replacement surgery for this group of patients. At Custom Vision Clinic we carefully assess your suitability for both PRESBYOND ™ LASIK and Lens replacement. If your natural lens is still crystal clear and has some residual accommodation ability then we should try and keep it in your eye.
If your cornea is not suitable for laser eye surgery or if your prescription is too large for laser eye surgery then lens replacement can be an excellent alternative to give you decreased dependence on spectacles. Also, if you have signs of cataract then it makes sense to perform lens replacement because not only will we provide you with spectacle independence but also we will have treated your cataracts.
Lens replacement surgery has been given various names: ‘lens exchange‘, ‘clear lens exchange’, ‘Clarivu ™ ‘. These names are all describing the same procedure.
At present there are only four clinics in the country which are able to offer PRESBYOND ™ blended vision LASIK. This may be the reason that most eye clinics will only offer you lens replacement.
