With advancing age, (beyond the age of 40) the crystalline lens in our eye becomes larger and harder and less able to change shape. The lens is used to fine focus and enable us to read in earlier life. The ability to do this decreases over time and we then require reading glasses.

Presently laser eye surgery does not correct presbyopia accurately and predictably and is not offered at Centre for Sight. However often patients in their 40s or older are able to read following laser eye surgery and this can be for many reasons, including mild residual shortsightedness or a multifocal cornea.

Another option is Monovision or "Blended vision" where one eye (the non-dominant) is purposely made a little shortsighted to enable reading. We do offer this treatment in those who are already wearing Monovision contact lenses. We do not offer this routinely as patients often find monovision / blended vision difficult to get used to and can be unhappy having one eye seeing very well at distance and the other (reading eye) blurred.

Correcting Presbyopia

The best available and highly effective solutions for Presbyopia are implantation of added value lenses : CrystaLens, ReSTOR, Acri.LISA and Tecnis.Multifocal. Centre for Sight has extensive experience in this type of refractive lens exchange surgery and is amongst the most experienced in implantation of CrystaLens in Europe.
