Contactology | Innova ocular
The Contactology Department of Innova Ocular IOA Madrid is made up of optometrists with a long professional record. It is them who assess and offer the solution to each patient in adapting any type of contact lens.
As well as disposable, conventional and gas permeable soft contact lenses, other lenses are adapted for visual rehabilitation after implanting intrastromal rings in patients with Keratoconus or post-lasik ectasia and corneal transplant, and even night treatment with orthokeratology.
The adaptation of a contact lens must be strictly personalised for each patient due to the multiple geometries, materials, curvatures, etc. We therefore recommend our patients to be treated by our contact lens specialists to study their case.
Keratoconus and irregular astigmatisms
This is an eye pathology that is characterised by the thinning of the central or para-central area of the cornea and usually causes high astigmatism producing changes in the visual acuity and refraction.
In initial stages of keratoconus a good vision can be achieved by correcting it with glasses or soft personalised contact lenses. The more advanced cases will require rigid contact lenses to correct the irregular astigmatism.
These astigmatisms can be corrected, even after the corresponding surgeries, with semi-rigid (RPG), semi-scleral or piggyback contact lenses.
This same treatment could be used for post-lasik ectasias and corneal transplants and the rest of corneal pathologies.
Orthokeratology (Orto-K) is a method that allows correcting the vision while sleeping and not having to wear glasses or contact lenses throughout the day.
This technique has been practices since the 1970's yet it is currently used with special technology that achieves better and faster results.
For that, a contact lens with a personalised design is used that the patient only has to wear while he/she is sleeping. This lens is not uncomfortable, due to the personalised design yet also because as we do not blink when sleeping the lens does not move.
Ortho-K works changing the shape of the cornea, which allows temporarily reducing myopia.
Unlike surgery, this treatment is reversible; it is suitable for any age group and allows, especially in the case of children, to control myopia slowing down ocular growth.
The correct use of these lenses would include using these lenses only at night, a good cleaning maintenance and attending the visits considered by the contact lens specialist.
The ideal candidates for this treatment would be the groups of children with a short-term myopia evolution (to control myopia), youths who can not undergo an operation yet, patients with dry eyes (intolerant to soft contact lenses), sportsmen and women, opponents and adults who can nor undergo an operation, among others. Patients with pathologies on the eye surface, keratoconus/corneal ectasia, sever eye dryness, high astigmatism; those who have undergone surgery or suffer from general diseases such as diabetes would not be suitable for this type of treatment.
Once the patient has started to use the ortho-k lens, his/her vision will be stable after 15-20 days counting from the first night he/she wears them, although it must be taken into consideration that the higher the myopia the grater the stabilisation time.
n short, it is a personalised technique in which each eye needs its own lens. It is only used at night and is as safe as any other conventional contact lens.
