Revolution in fitting of postoperative and irregular corneas
The “HydroMed” soft contact lens is a revolutionary concept, designed for fitting corneas with irregularities.
Both, the back and the front surface are individually parameterised.
The unique back surface is designed to avoid pressure on any part of the irregular corneal surface (improving comfort and tolerance) whilst also promoting a smooth refractive front surface
The front surface of the contact lens can be optimised to compensate irregularities. Because the resulting lens periphery is similar to a standard lenses comfort levels are excellent. New Silicone Hydrogel materials allow an optimised oxygen permeability for the cornea.
The “HydroMed” is available in two versions, bi- and tri-curve back surface. One or other variant can be selected depending on the shape of the cornea.
After refractive surgery (post-LASIK) the bi-curve version will match the flat centre and steeper periphery
For Keratoplasty (PKP) the tri-curve version is recommended
Other irregularities as well as those in the conjunctiva should be considered ocasionally.
Both curves and diameters (central and peripher) can be parameterised individually by the Bi-curve contact lens to produce the best possible fitting result on the patients cornea.
Made up of two peripheral and one primary curve each are individualized based upon the corneal topography. The corresponding diameter of the contact lenses is also freely selectable.
The “HydroMed” is available in all materials supplied by SwissLens. So the best contact lens material can be selected depending on the nature of tears and oxygen demand. Currently seven different materials are offered.
Link to list and recommendations
Fitting HydroMed is easy and time efficient.
There are two possible fitting methods.
The HydroMed S1S set includes 4 lenses. It is perfectly made for post-Lasik cases
For the HydroMed S2S exist no trial-set at the moment.
Given information about the topography and vision, SwissLens will recommend the initial trial lens. After this first lens has been observed in situ any modifications can then be applied to a subsequent lens.
The trial lenses are manufactured with cyl -0,01 dpt. Using an autorefractometer and after a classic eye examination you can determine the definitive correction Sph/Cyl/Axis.
The parameters can be changed. Parameters outside the delivery ranges are possible after consultation our professional service team. For example cyl > dpt 8.00DC as far as technically feasible. We recommend to work with the online order tool.
