Vision correction for people under 45 with Large spectacle prescription
- More than minus 8 dioptre (i.e -8.5 or -10 etc ) or
- More plus 4 dioptres (i.e +5 or +4.5 etc ) and/or
Furthermore if astigmatism (the second number in a standard prescription) is :
- >5 dioptres (whether plus or minus)
For people who have spectacle prescriptions above certain dimensions (click on the info box) we now have a range of specialised lens implants that can help to correct eyesight and minimise the need for glasses.
As the natural lens has not yet started to show the characteristic age related loss of near vision, we at Bettersight would not usually recommend a Refractive lens exchange unless the spectacle prescription was very large/extreme or there were already some early signs of cataract formation.
For large value prescriptions laser vision correction is not usually feasible as too much corneal tissue would require sculpting to correct the prescription. This can lead to unwanted visual aberrations and some decline in vision quality.
For this reason lens implants have been created that are designed to be inserted into the eye and to work in conjunction with your natural lens.
These marvellous lens implants are called Phakic lens implants.
