Keratoconus is an ocular condition in which the normal structure (shape) of the cornea gradually thins, creating a conical type of cornea and resulting in a gradual increase in astigmatism. It is a condition that usually occurs in the ages of 15-20 years.
People who have keratoconus, depending on the type of keratoconus and its extent, have very different needs when it comes to its treatment. Some can achieve very good vision with the use of simple glasses of small degrees, some can mainly see better with one eye, some achieve good vision only with the use of contact lenses and with wearing their auxiliary glasses the possibilities are significantly limited.
Therefore, if we want to help and make life easier for the people close to us with keratoconus, we should consider the following:
- People with keratoconus require some extra time during the day to apply their contact lenses. The use of special contact lenses should not be continuous for many hours (maximum 14-16 per day), so a person with keratoconus should be given the required time for breaks, in order to rest their eyes.
- You need to plan some activities differently, based on their needs. Activities that require a lot of detail or night driving can be especially demanding for people with keratoconus. Therefore, you should plan work shifts, travel curriculums, lighting conditions and workplace ergonomics, according to their needs.
- People with special contact lenses, recommended by specialized eye health professionals, have better vision. Patients with keratoconus are often provided with different correction prescriptions, which have significant differences. This is perfectly normal. Since their astigmatism is asymmetric, there are many different degrees in the patient's visual specter, and only some of them can be corrected with glasses. In addition, the optical diaphragm of our eye, the pupil, changes its diameter based on the current lighting conditions. This fact alone could result in different prescriptions. Better vision can only be achieved with the use of special contact lenses (ex. Delta Conus, Epsilon, Dualascon). Optical health professionals can choose the best possible solution for the needs of each individual.
