MC Clinical Notes Cont’d
Rationale for KeraSoft ® fitting
MC had heard of KeraSoft ® lenses and wished to see if he could achieve sufficient levels of vision to avoid
undergoing corneal graft surgery. He had been informed by his hospital practitioner that no rigid lens type
would offer him sufficient visual acuity to enable him to continue driving.

When the flat fitting RGP lenses were discontinued, it was expected that the cornea would become steeper,
as it went through the demoulding process. The patient was advised that he may require steeper KeraSoft ®
IC lenses to be fitted at subsequent visits as the cornea settled.
MC decided to go ahead with the fitting as the improvement in his acuity was better than he had anticipated.
The above KeraSoft ® IC lenses were supplied. After 2 days wear, he reported a significant reduction in
photophobia, a considerable increase in comfort and achieved 18 hours wear comfortably. MC kept in
contact during the following weeks and his acuity was regularly checked to ensure he did not fall below the
driving standard whilst his corneal shape fluctuated during the “demoulding from RGP” process.
3 month follow up
Both lenses now appeared tighter than at initial fitting but movement was still acceptable and the left lens
rotated 15 degrees clockwise (CW). MC reported vision had reduced slightly but was still better than with his
previous RGP lenses.
