People with age-related diopters (presbyopia) usually have a subspecialty examination.
The subspecialty examination is a detailed examination and consists of anterior segment examination, as well as diopter determination (new diopter, diopter change, hidden diopter examination) and examination of the posterior segment of the eye (fundus and optic nerve).
If necessary, additional diagnostics such as OCT are performed.
OCT is an Optical Coherence Tomography – it examines the structure of the macula and the optic nerve to find out if there are any defects in that structure that are invisible when viewed with a magnifying glass. In people over 60 years of age with diopters, this diagnosis is made due to the possibility of macular degeneration.
If the patient is interested in multifocal lenses that allow vision at all distances (near, far and middle), an examination for multifocal lenses is performed.
The examination for multifocal lenses consists of:
- Determining visual acuity;
- Measurement of intraocular pressure;
- Examination of the fundus – retina;
- IOL master.
The examination is performed by a team of ophthalmologist, optometrist and nurse. The team is trained to make: an appropriate detailed examination of the eye, appropriate measurements of the intraocular lens and all diagnostic tests needed to detect the presence of a hidden eye disease, which could affect the quality of vision in the future.
