After discussing various contact lens options, actual diagnostic contact lenses will be placed onto your eyes. Your Optician will then perform another slit lamp examination to determine if a particular lens fits correctly, ensuring proper movement of the lens. A visual acuity test will be then be performed to determine how well a contact lens corrects your vision.
If you’ve never worn contact lenses, you will be taught the proper way to insert, remove and disinfect them. Most Opticians will place extreme importance on hygiene, cleanliness and disinfection. They will probably allow you to wear the contact lenses for a week and then return for a follow-up visit. At the follow-up visit, they will reassess the contact lenses and solve potential problems. Either a new lens will be tried or the prescription will be finalized.
If your vision and comfort is not satisfactory, additional follow up visits may be required. Some types of lenses, such as toric lenses for correcting astigmatism or multimodal lenses for correcting presbyopia, tend to take more time to achieve a perfect fit.
Fitting contact lenses is both a science and art that requires a certain level of expertise.
