Cataract is when the natural clear lens that sits behind our coloured iris and is responsible for fine focusing gradually goes cloudy leading to a reduction in overall vision. Cataract Surgery is the most common surgical procedure undertaken in the UK. It can be undertaken in approximately and can be very routine. However, it is not minor surgery and should not be trivialised. Once the cloudy lens has been removed a clear artificial intraocular lens (IO
There are numerous choices of lenses available for implantation inside the eye to achieve a range of desired outcomes. These include monofocal, extended depth of focus (EDOF) lenses, toric lenses and trifocal multifocal lenses.
Not all lenses are suitable for all patients. It is not the lens but the surgeon which is the most important determinant of a “successful outcome”. A skilled surgeon will not only perform the surgery safely, they will also have the knowledge and experience to choose the appropriate lens for to achieve the desired outcome for the patient.
Monofocal IOL
These lenses correct only for distance or near. Usually used to correct for distance whether they are shortsighted or longsighted. They will require reading spectacles.
Dr Tint only uses the highest quality monofocal lenses on the market allowing his patients to achieve “HD” quality vision.
Extended Depth of Focus Lens (EDOF) IOL
These are new lenses are designed to give a more seamless visual transition from distance to near. They are a variant of multifocal lenses. One such IOL is the Tecnis Symfony lens. Dr Tint was the first in Edinburgh to implant this lens.
Trifocal IOL
These lenses are designed to all the greatest freedom from spectacles. They focus for distance, intermediate and near. There is a high success rate for total spectacle freedom.
Toric IOL
These IOLs are available in as monofocal, EDOF or trifocal and help to correct astigmatism. They allow for better vision without spectacles.
Blended Monovision
This is a concept whereby the dominant eye is made good for distance whilst the non-dominant eye is corrected to see intermediate/near. The difference between the two eyes are kept as small as needed to allow the patient to blend the two eyes to see both distance and near.
