Question
I had a cross linking procedure 6 weeks ago due to post lazek ectasia,now I am suffering from hypermetrope, would it stay as is or improve back
Also is there any other solution as contact lenses after the procedure than the RGB since they are real tough to use, I have heard about hybrid lens, and scleral fixation which one to use and from where to purchase Thanks
Answer
Dear Ahmed,
C3R is done to prevent progression of the anterior bulging of the cornea, however since this is after a laser procedure on the cornea, it may or may not stop progression. It has been shown in literature that some cases of post LASIK ectasia continue to progress even after C3R and may need to repeat C3R.
Hence, it requires you to follow up with the centre for topography tests to monitor this.
Usually, we need to wait till 3 months minimum, repeat the topography and compare it with the pre-C3R topography... if its the same, then we need close followup... if its worse, then probably the ectasia is still progressing... then we need to take a call as whether to wait and watch or repeat the C3R.
Post C3R visual rehabilitation has many options like using spectacles, contact lenses ( best fitting - ROSE - K lenses), surface ablation, INTACS, PHAKIC IOL, other incisional corneal procedures for astigmatism... etc. but this can be decided only after we evaluate the patient and hence can be best answered by your treating doctors.
Hope this helps.
