Cataract surgery involves removing the natural lens which has become discoloured and hard and replacing it with an intraocular lens (IOL). Laser cataract surgery is also available and can offer cataract patients an alternative option for the surgery.
Most IOLs are fixed mono-focal lenses designed to deliver optimum vision, they can be used to provide vision for distance and near with ‘monovision’. Other types of IOLs include bifocal, multifocal or extended depth of focus IOLs which provide focused vision for both distant and for reading distance in the one IOL; in many cases, this will mean reading glasses may only be required for low light or very small print.
Your doctor will advise you of the best option for you depending on your individual requirements and lifestyle. Cataract surgery is usually done under local anaesthetic in a day surgery environment and takes approximately half an hour. Cataracts cannot be cured by any type of medication, eye exercise, alternative therapy, diet or glasses. Surgery is the only way to remove a cataract.
