What are contact lenses?
Contact lenses are a great option to correct refractive errors and also, as a treatment for certain ocular pathologies. They are suitable for myopia, hyperopia, astigmatism and presbyopia and adapt to the patient’s visual requirements and lifestyle.
They allow the patient to have an optimal vision with a greater vision field than when using glasses and are recommended when practicing some sports and in certain occupations.
Nowadays, the use of contact lenses is not only limited to correct refractive errors and for esthetic purposes, but also involves the treatment of some ocular pathologies.
- In people who suffer important anisometropia (significant difference in focusing ability between eyes), as they do not tolerate wearing glasses which have an optical correction that differs by more than 3 diopters.
- In pathologies involving corneal deformation such as irregular astigmatism or keratoconus, contact lenses are sometimes the only suitable optical correction, as life quality when using glasses is very poor.
- Therapeutic lenses: in some occasions, contact lenses are used as an “ocular bandage” in order to protect the eye surface so that the eyelids do not rub against it, avoiding pain and facilitating corneal regeneration. Contact lenses are indicated for this purpose in chronic or traumatic corneal ulcers, after corneal foreign body extraction and in corneal degenerative pathologies such as bullous keratopathy, corneal dystrophy, etc.
The type of contact lenses to be worn depends on a series of parameters including the patient’s refraction power, eye characteristics and lifestyle.
Which factors influence adaptation?
- Hours of regular daily use
- Weekly use
- Tear type and quality
- Eye measurements (cornea, curvature, pupil diameter, etc.)
- Necessary oxygen supply
Custom adaptation carried out in Clínica Rahhal enables patients to have the best possible vision keeping eyes healthy.
Every eye is unique, so in order to achieve maximum quality vision, custom adaptation is necessary.Contactology Unit
