Intacts - Frequently Asked Questions
The INTACS procedure does not prevent you from having a corneal transplant in the future if this is required. However, INTACS may ultimately be found to delay or prevent the need for a corneal transplant, by helping to keep the cornea nearer to its natural shape.
INTACS treatment may sometimes not provide the desired outcome; the INTACS segments may extrude and need to be removed; the cornea may attract growth of blood vessels and the segments may need to be removed; and sometimes there can be thinning of the cornea over the INTACS segments.
The main alternative to INTACS is to continue with glasses or contact lenses as the main route to visual rehabilitation. If these have been unsuccessful they are likely to remain so as time passes by.
INTACS have a high success rate for treating contact lens intolerance and allowing patients to wear contact lenses more comfortably.
The success rate reduces the more advanced the keratoconus, so it is not possible to provide an overall success rate as a % since every case will be different and should be assessed individually.
The shape of the cornea will typically take three months (or longer) to stabilise, and during this time your vision will fluctuate. Only once the cornea has become stable should you consider glasses or contact lenses for definitive correction of any residual refractive error.
Some people choose to seek temporary glasses or contact lenses during the recovery period. There is no objection to this, but the prescription may change until the cornea becomes stable.
